LIGHT BULBS - All you need to know - VERY BRIEF

LED lightbulbs save you the most money and last the longest, although the initial cost of the bulb is higher (now around $10). 2700K to 2800K is the bulb color you have used all of you life - ANY other colors (lightbulb temperatures) will probably bother you - look much too white for normal use in lamps and fixtures. NEW LABELING LAWS call Bulb Temperature LIGHT APPEARANCE. Some names for 2700K bubs are Soft White and Warm White. LEDs and Incandescent lightbulbs do NOT contain Mercury. CFLs, Halogen and Fluorescent bulbs DO CONTAIN MERCURY. Some caution should be used with bulbs containing mercury if they break or when you dispose of them. LEAKY SWITCHES (Lighted switches), DIMMERS and TIMERs will destroy CFLs Incandescent lightbulbs may be used with any Timers or Dimmers LED lightbulbs (check label on bulb package) may be used with most Timers, Dimmers and Lighted Switches. CFLs can ONLY be used with mechanically activated switches or dimmers otherwise, you will burn it up very quickly NOTE: most CFLs are NOT dimmable. NOTE: many LEDs are NOW dimmable - READ THE BOX Halogens can be used with any Timer or Dimmer I BELIEVE - check the labeling 300 watt Halogen bulbs in lamps have set many a home on fire - I (my opinion) do NOT recommend them - they are too hot for me. In fact, I try not to use Halogens at all (my opinion). READ THE LABEL THINGS CHANGE - I MAY HAVE BEEN INACCURATE. Should “Light Bulb” Be One Word, or Two? - ONE WORD

BULB TYPES - BACKGROUND INFORMATION

CFL - Compact Fluorescent ESL bulbs produce about 40 lumens per watt, compared to 7-24 for incandescent, 12-36 for Halogen, 44-80 for CFL, and 30-60 for LED. ESLs - Electron Stimulated Luminescence - bulbs are the wave of the near (end of 2016 ?) future. Fluorescent Halogen Incandescent (normal light bulbs) LED - The BEST OPTION FOR NOW - cheapest, safest, most versatile

LUMENS per Incandescent Bulb

Incandescent bulbs are the regular bulb type, used in the last 100 years. DIFFERENT BRANDS OF BULBS PRODUCE DIFFERENT AMOUNTS OF LIGHT: I would NEVER buy a "60 watt" bulb that outputs much less than 800 Lumens. Some bozos are calling a 570 to 660 Lumen LED a replacement for a 60 watt bulb. A Typical 300 watt incandescent bulb produces about 6200 Lumens NOT the lower 3900 lumans I've seen quoted for a 300 watt lightbulb A Typical 200 watt incandescent bulb produces about 3890 Lumens A Typical 150 watt incandescent bulb produces about 2780 Lumens A Typical 100 watt incandescent bulb produces about 1275 Lumens A Typical 75 watt incandescent bulb produces about 1110 Lumens A Typical 60 watt incandescent bulb produces about 800 Lumens A Typical 40 watt incandescent bulb produces about 490 Lumens A Typical 25 watt incandescent bulb produces about 210 Lumens A Typical 15 watt incandescent bulb produces about 10 Lumens A Typical 7 watt incandescent night light bulb C7 ~ 30 Lumens CLEAR A Typical 7 watt incandescent night light bulb C7 ~ 20 Lumens WHITE (not clear) A Typical 4 watt incandescent night light bulb C7 ~ 17 Lumens CLEAR A Typical LED night light bulb - C7 ~ 4 Lumens White LED NIGHTLIGHT BULB LUMENS HAVE GONE UP - I CAN NOT FIND NEW LUMEN RATINGS. I, PERSONALLY, CONSIDER THIS (4 Lumens) TOO DIM TO BE USEFUL. But I have switched to LED nightlight bulbs - not as bright as the incandescents, but I am tired of the incandescents burning out. Night light and energy saver light test results - Updated 11/16/2009 "Beware that many low power white LEDs, even good ones, fade significantly within 10,000 operating hours at "normal power" LEDs, Lumens and Brightness - "How many lumens are they?" "LED ratings of 25,000 mcd become conceptually difficult to understand when we're accustomed to light being expressed in terms of lumens. Published lumens represent the sum of all the light emitted by the bulb in all directions." ESL bulbs produce 40 lumens per watt, compared to 7-24 for incandescent, 12-36 for halogen, 44-80 for CFL, and 30-60 for LED (10/2009).

Bulb TEMPERATURE (the color you perceive)

NOW called LIGHT APPEARANCE

2700K-2800K is THE same bulb color that you have used ALL your Life. New USA labels now call this Light Appearance. The higher the number, the whiter and then the blue, the color.

Compact fluorescent Light Bulbs (CFLs)

Compact Fluorescent Bulbs are similar to fluorescent bulbs, but come in smaller sizes so that they can (often) be used to replace standard light bulbs. The ballast for a CFL is built into the bulb (as opposed to non compact fluorescent bulbs). Typically, a CFL creates the same amount of light as an incandescent bulb, using about one-fourth as much energy. Most CFLs these days are using electronic ballasts, rather than magnetic. CFLs will dim slightly with age. I NOW USE ONLY LED BULBS IF THE CORRECT AMOUNT OF LUMENS ARE AVAILABLE. Neon lights up in the visible spectrum when ionized. Fluorescent lights ionize mercury vapor which gives off ultraviolet light (outside the visible spectrum) this in turn energizes phosphor which coats the inside the tube and causes it to fluoresce thus the name fluorescent Light. Click here for more information about Fluorescent Bulbs H.I.D. (High Intensity Discharge) is an Arc Lamp. It's called an Arc Lamp because it shoots an electrical arc between two electrodes and the light given off is created by that electrical arc. HID lights are used in more expensive cars and work very well.

RECYCLE CFLs - they contain some Mercury

Fluorescent Bulbs contain a small amount of dangerous Mercury. Please check with your city on how to dispose of old CFL bulbs. You can also check: Where/How to recycle your old CFLs (fluorescent Bulbs). What to do with broken CFLs - SNOPES I just noticed (10/1/2008) that Home Depot now recycles compact CFLs (but not tube-type fluorescent lights). Presumably, Lowes might also be recycling CFLs? CFLs have a projected life of between 8,000 and 12,000 hours. A CFL will typically pay for itself in about 500 hours. Most CFLs, these days. use electronic ballasts, rather than the older magnetic ballasts. Magnetic ballasts have a hard time starting at temperatures below 20 degrees Fahrenheit. Electronic ballasts can usually start at temperatures around a negative 20 degrees Fahrenheit - CHECK THE PACKAGE LABEL for any details. However, magnetic ballasts will work with more photocell detectors, motion detectors, etc., so be careful when using CFLs with these types of "switches" (the bulbs will burn out much faster). A Relative says CFLs are too blue - she is buying the wrong ones, and probably a long time ago. Mine are the same apparent color as incandescent bulbs, and can now be bought in the following hues: 1] SOFT WHITE (my favorite) 2] BRIGHT WHITE and 3] DAYLIGHT. For more information about Bulb colors, warmth & Brightness, click HERE I get most of my CFLs at Home Depot (their latest brand is N:Vision) and some unusual candelabra base types at Lowes. Every time I buy a new CFL, I see that they have, again, gotten physically smaller, so that they will fit into more locations. They also keep getting faster, so that you don't see any delay between when you turn it on, and when you see its light. You can also get "covered" CFLs - they look more like a standard incandescent bulb. We DID use covered CFLs in most of our lamps (you can even clip a lampshade to them), and in places that uses the long skinny "pole lamp" bulbs. Some CFLs are supposed to be dimmable - I have not tried dimmable CFLs. We even use CFLs in our ceiling fan lights. I also have outdoor CFL Floodlights - they put out the same amount of light as 90 to 150 watt incandescent flood lights, and consume UNDER 15 watts. WE NOW USE LEDs, NOT CFLs when we can find LEDs that will do the job. Here are some of the CFL types that we use. You may not like them. Prices and stores given ONLY to give you some idea of the cost, and could be incorrect. READ THE PACKAGE - Some wattages listed indicate comparable incandescent light output (i.e., "60 watts"), while others list the actual number of watts consumed by the CFL. If in doubt about the amount of light produced by the CFL, check the number of Lumens (amount of light) produced.

FLUORESCENT LIGHT BULBS COLOR/BRIGHTNESS

The higher the color rendering index (CRI) of the bulb, the more true the colors will appear. I've also seen CRI stated as: cri/irc: 60 (for a CRI of 60. A "cool" white bulb commonly has a color temperature of 4,100K. This is in the low range of blue color, similar to ice. A "warm" fluorescent bulb often has a color temperature of 3,000K. It imparts a more orange / red light on objects. If you decorate with reds, browns, and oranges, you want to illuminate these rooms with bulbs that have a color temperature in the 2,750 - 3,000K range. if you happen to like green carpets, or blue colors, light these rooms with bulbs that produce color temperatures of 4,000K or above. They use a color rendering index (CRI). It is simply a scale of 0 to 100. The closer a bulb is to 100, the better job it does at rendering true colors. If you want 'neutral' looking CFLs you have to find some 4100k. The only decent looking CFLs above 4100k are enhanced CRI bulbs that are a specialty item. - GE sunshine 5000K CFL 5000k / high CRI is pretty nice to work under, but you aren't going to find them for cheap. Reveal Kitchen & Bath COLOR = 2600 K (a little too pink for me) = 1125 Lumens = CRI 60 Light Bulb Color Temperature Color rendering light sources Kruithof curve - Wikipedia The Kruithof curve relates the illuminance and colour temperature of visually-pleasing light sources - Wikipedia The Color of White: Is there a "preferred" color temperature for the exhibition of works of art?

HERE are some of the more special types of CFL that we use: Feit Electric 2-Pack 7 Watt CFL Chandelier Bulb (Candelabra base w/standard adapter) - $9.98/for Two - LOWES "75 watt" CFL Flood Light (uses 23 watts) - $ 8.48 - Lowes Yellow, covered, CFL (Bug light) - uses 14 watts - $ 7.98 - Lowes 25 Watt Compact Fluorescent Light Bulb - for 3-way lamps - Lowes Bright Effects #276505 60 watt Candelabra Base - smaller than a normal 15 watt bulb. We are using these in a ceiling fan as 40 watts was not enough - Lowes. Some (all?) magnetic ballasts should be able to run on digital timers, so they say - CHECK THE PACKAGE. I, PERSONALLY, WOULD NOT RUN ANY FLUORESCENT BULB ON A DIGITAL TIMER that does not use a physically solid electrical contact to supply voltage to the bulb - Click here for information about Timers safe for CFLs. Compact Fluorescent Lights (CFL) information - Boulder County Good information about when and when not to use CFLs.

LEAKY Switches, Dimmers and Timers

Most Timers, Dimmers and Photocells allow a small amount of electricity to flow through the bulb (anything plugged into them) at all times - this causes the CFL to attempt to start without having a sufficient starting voltage, causing damage to the CFL. Most CFLs can NOT be safely used with timers, dimmers, photocells or completely enclosed housings. LIGHTED SWITCHES also leak a small amount of Electrical current (to power the light) and they will also shorten the lifespan of a CFL. My electrician confirmed my suspicion that lighted wall switches also leak voltage and could possibly shorten the life of fluorescent bulbs. We detected a current/voltage leak on my three- way lighted wall switches, and replaced them. Timers that DO work with CFLs Dimmable CFLs - Wikipedia Most CFLs are not dimmable, and, if they are, may require a new dimmer. Many new CFLs are rated to start at zero degrees Fahrenheit (older ones at 32 degrees F.). If they do start at these low temperatures, they probably will not output their full, normal amount of light. You should not use a CFL outside unless it states that it can be used in outside situations. Most CFLs rated for outdoor use have an additional glass/plastic cover over the bulb, to protect it from the environment. I have used regular CFLs in porch lamps the have glass covers to keep rain from striking the bulb. CFLs are usually easier on the eyes, when reading, than incandescent (normal) bulbs. CFLs do tend to get gradually darker as they age, so they will put produce less light as they age. While CFLs continue to get smaller in size, they can still be larger than an incandescent bulb, so check to see that the desired CFL will fit in the your bulb housing, especially if the housing has a cover. It is now possible to get both CFL and LED lightbulbs smaller than normal incandescent bulbs, although just above the base might be larger - check it yourself. Some electronic timers and photocells contain parts that are incompatible with compact fluorescent lights When to use CFLs USE LEDs wherever you can get one that fits and outputs the correct number of lumens (it's cheaper in the long run). What's the difference between a compact fluorescent light bulb and a fluorescent bulb?

CFLs should save you this many $$ over incandescent bulbs

CFLs should save you about 75% in electrical costs over it's lifetime. CFLs Last up to 10x longer than traditional (incandescent) bulbs. CFLs seem to be warranted for about 10,000 hours of use, or about 9 years at 3 hours per day, every day. Some of these are much bigger (physically) than others, There are even Mini sizes. Ensure yours will fit. Savings depends on the Brand of CFL and is based on actual watts consumed over the expected lifetime. CFL 100 watt soft white replacement should save you about $ 101 in electrical costs should cost you about $ 2.77 a year in electricity lightbulb cost ~$ 3 EACH in a FOUR Pack ($12) consumes 23 watts Outputs 1600 Lumens CFL 75 watt soft white replacement should save you about $ 61 in electrical costs should cost you about $ 2.29 a year in electricity lightbulb cost ~$ 3 EACH in a FOUR Pack ($12) consumes 19 watts Outputs 1200 Lumens CFL 60 watt soft white replacement should save you about $ 51 in electrical costs should cost you about $ 1.69 a year in electricity lightbulb cost ~$ 2 EACH in a FOUR Pack ($8) consumes 14 watts Outputs 900 Lumens CFL 40 watt soft white replacement should save you about $ 39 in electrical costs should cost you about $ 1.08 a year in electricity lightbulb cost ~$ 1 EACH in a FOUR Pack ($4) consumes 9 watts Outputs 550 Lumens Incandescent light bulb - Wikipedia "Green" Light Bulb Buying Guide

ESLs - Electron Stimulated Luminescence

ESL bulbs are the wave of the near (mid 2010 ?) future. ESLs produce about the same light for the same wattage as CFLs. I believe that ESL use less heat than CFLs for the same wattage. ESLs do NOT contain mercury. ESLs are fully DIMMABLE. Instant ON. ESL bulbs produce 40 lumens per watt, compared to 7-24 for incandescent, 12-36 for halogen, 44-80 for CFL, and 30-60 for LED.

HALOGEN BULBS

Halogen Bulbs save about about 25% energy savings over incandescent bulbs. I have very little use for Halogen Bulbs as replacements for incandescent light bulbs. I use LED bulbs instead - for the most savings. Many fires have been started by high-wattage halogen bulbs (300 watt torchieres). I am using some Halogens in the bedroom and makeup areas. Halogen bulbs produce a brighter, hotter light than do incandescent bulbs. Halogen bulbs are about 20% more energy efficient than are incandescent bulbs. see also: HEADLIGHTS I have fluorescent tube lights (30 watts) under some of my cabinets. I have noticed that items placed on the bottom shelf of these cabinets get very warm (in my opinion) - too warm for me to want to ever use these fluorescent lights when I am not in the house, for fear of a possible fire (my opinion). Halogen bulbs are even hotter. I, personally, would NEVER use a Halogen bulb under a cabinet. Since fluorescent bulbs consume about 16% of the energy of an incandescent bulb for the same amount of light, and halogen bulbs consume about 80% of the energy of an incandescent bulb, why would I want to use a more expensive-to-use halogen or CFL bulb rather than an LED? Halogen life spans seem to be 2000 to 2500 hours and they cost about Four ($4) dollars for a 75 watt halogen bulb. Just (7/2014) looked at a 100 watt Halogen floodlight replacement - it says it has a 7.7 year (8400 hour) lifespan (usually measured at 3 hours per day, everyday). Incandescent bulbs typically have a lifespan of between 750 and 1250 hours, and cost about Fifty Cents for a 75 watt incandescent bulb. CFLs have a projected life of between 8,000 and 12,000 hours. A CFL will typically pay for itself in about 500 hours. CFLs can NOT be successfully used with most electronic timers or photosensors, as these devices leak small amounts of current, causing the CFL to continually try to start when the voltage is too low - this quickly burns out the bulb. Timers that DO work with CFLs. You should be able to use Halogen bulbs with electronic timers, photo-sensors and motion detectors - just remember that these bulbs are hotter than incandescent bulbs.

LED - Light Emitting Diode - SAVES THE MOST MONEY

Most DIMMERS will NOT KILL CREE LED bulbs. CHECK THE AMOUNT OF LIGHT OUTPUT FROM AN LED, BEFORE YOU BUY IT. There are still a lot of TOO CHEAP LEDs being sold. Typical LUMENS per regular incandescent bulbs READ THE LABEL THINGS CHANGE, I MAY HAVE BEEN INACCURATE. LEDs contain NO mercury, but CFLs, Halogen and Fluorescent bulbs DO. I am now (2015) using CREE LEDs exclusively (if they have the size/lumens. They are made here in North Carlina, and have been rate the best by several big name companies, The are sold by HOME DEPOT.

LEDs should save you this many $$ over incandescent bulbs

LEDs provide 85% more energy savings as compared to incandescents. LED lightbulbs Lasts up to 25x longer than traditional bulbs. Expected lifetime for Cree is 25,000 hours (22.8 years). Warranty is 10 Years (at 3 hours per day, everyday). I prefer Cree LEDs, in my personal opinion, it is the best brand of LED. Consumer Reports also rated it the best (this could change). CREE has a lot of LED patents, and they are MADE in the USA (North Carolina). ENSURE Your choice will fit, including the diameter. Savings depends on the Brand of LED and is based on actual watts consumed over the expected lifetime CAREFUL - Home Depot/Cree web pages seems to default to BRIGHT WHITE. You do NOT want Bright White, YOU WANT SOFT WHITE. SOFT WHITE IS THE ONLY BULB APPEARANCE YOU HAVE EVER USED IN YOUR LIFETIME. Apparently, (Cree at HD) you can also order SINGLE (standard packaging), FOUR or FIVE PACK packages. Ensure you order/look at the correct package. THESE CREE and ECOSMART LIGHTBULBS ARE AVAILABLE FROM HOME DEPOT:

More information about LEDs How fast can LEDs replace fluorescent light? I expect ESLs to replace LEDs for household use, even before LEDs make sense for household use. CREE Lighting - North Carolina, USA - bulbs made in USA LEDs almost never wear-out (typically last 100,000 hours). They usually consume the less power and run cooler than other "bulbs" (except, possibly, for ESLs. retrofit LED bulbs out later this year that can pay their replacement costs in one year We are using two different types of under cabinet LED light fixtures (obtained from Lowes, but not listed on their website 1/2008). My favorite is: Portfolio Item #240230 (50505/05) LED Puck Accent Lighting - a 4" round LED fixture with a push on, push off switch and 20 Bright white LEDs. We are using these to light our Lowboy cabinet with stained glass doors, and in my closets and other small areas. I will also put some under kitchen cabinets and many closets. Portfolio Of course, I no longer see this in retail stores - may no longer exist? Another useful LED fixture is the Portfilio #50509/05 and #50510/05 LED Strip Light Accent Light. This comes in both a 16.5 inch long (14 LEDs) and a 24 inch long (20 LEDs) LED bar. These LED light bars cane be joined together. I did not find the LEDs in these units to be as bright as the Puck LED light (see above). Of course, there are fewer LEDs in these units than in the LED Puck, but I still think that the LEDs in these are not as bright as in the Puck light. I can find a lot of useful places to put these. We bought ours from Lowes, but these are not on the Lowes web site. Of course, I no longer see this in retail stores - may no longer exist?

LIFESPAN of a Lightbulb

New USA labeling laws require that the expected lifespan in total hours and in length of time (days/years) (based on being in use for 3 hours per day, every day, over the lifespan of the bulb) BE ON THE PACKAGE, at least for normal size/shape lamp bulbs. You can often find the total estimated, bulb lifetime savings in use of electricity of the lightbulb, in the small print on the lightbulb package. Halogen life spans seem to be 2000 to 8400 hours and they cost about Four ($4) dollars for a 75 watt halogen bulb. Just (7/2014) looked at a 100 watt Halogen floodlight replacement - it says it has a 7.7 year (8400 hour) lifespan (usually measured at 3 hours per day, everyday). Incandescent bulbs typically have a lifespan of between 750 and 1250 hours, and cost about Fifty Cents for a 75 watt incandescent bulb (if you can still find them) - it will be illegal to sell standard size and wattage incandescent lightbulbs soon (in the USA) if it is not already illegal. CFLs have a projected life of between 8,000 and 12,000 hours. A CFL will typically pay for itself in about 500 hours. LEDs can have a life expectancy of 100,000 hours. I am seeing warranties for normal LED lamp bulbs of between 12,000 hours (VERY LOW) to 250,000 Hours. CHECK THE LABEL when estimating costs.

NEW USA LABEL ALSO REQUIRES

1) That expected cost of use per year (based on 3 hours per day) be listed. 2) The Color of the bulb, in Degrees Kelvin, be on the label. Remember, you have only used bulbs in the range of 2700K to 2800K all your life. The new label calls this LIGHT APPEARANCE.
