The led would likely be accompanied by a bridge rectifier and capacitor to stay on full time.

I should try that. I know that blue food tends to look unattactive to people. Perhaps you should market that.

Most of the LEDs for sale at Home Depot & Lowes emit a blue "cold' light much like the el-cheapo "cool" fluorescent lights. The "deluxe warm white" fluorescent light is a broad spectrum light which produces about a 1/3 less lumens and last about 33% longer. A "cool" light is great in a morgue but not around living people. Office buildings use cool lights because they are cheap.

If and when the LEDs mgf. start selling a warm or broad spectrum light, I be first in line.

Blue or narrow spectrum lighting can be very irritating to some people!

We have some LEDs with a more pleasant light color, but they were in the $30 to $50 range. Super Bright LEDs - MR16 and E27 Bulbs is one source.

i think a sociology book i had in college explained some experiment where they used weird lighting on foods and recorded appetite changes. it was quite profound.

Lighting does have an effect on psycology, but keep in mind here, all I am trying to do is NOT put a 40 watt heater inside my fridge.

When I am looking at my food and eating it, it's out on my dinner table.

The light in the fridge is only on for 6 seconds at a time. As long as I can see in there, it wouldn't matter if the light was red or green or whatever.

I have had the LED lights in there for a long while now, they were inexpensive, and I have had no problems running them.

Some people get uneasy when introduced to something unfamiliar to them. My sig other says LED and CFL light makes her "uneasy". Based on other observations, I believe some people do not like anything that saves money, especially if they do not have to earn that money. Change is BAD!

Arminius - the building management peeps where I work have been slowly changing out lighting over the past few years. If someone "catches" them, there are a lot of complaints. If they manage to do it over a weekend and none of the workers know, complaints are few. FWIW IMHO most of the complainers are people who spend more time working on commitees and events than the J.O.B.

(boy, am I gonna get it now from some sectors)

I think some people read reports of nausea and such then instantly assume the change is affecting them the same way, whereas if they don't recognize the change, they don't notice any difference to the way they feel. That said, there is a very legitimate beef with LEDs that aren't running off of smooth bridge rectifiers. If they are only running on the half cycle, they will flicker very noticeably and create visual artifacts when moving. Fully rectified supplies don't really produce a consciously noticeable flicker, but it still plays with the senses of some people in a negative way. Only a smoothed DC supply can provide a fully flicker free experience - and that is often the big difference between cheap LEDs and more expensive ones.

I have little doubt that the fridges that instantly nauseate some people are due to manufacturers cutting corners on the lighting power supplies.

I have CFLs in most lamps and fixtures in my house. I can't stand their colors (not all are the same which annoys me too...), so in my preferred reading locations I still have old fashioned bulbs. I also use lower wattage bulbs in places I can't physically fit a CFL (though I've found some that are ALMOST small enough to fit...). Most CFLs need a bit of time to "come on" fully, so are great in areas that need to stay lit longer. Such as, my front outdoor lighting. I do use regular tube flourescents in my garage. I've tried a variety of bulbs but still prefer the "soft" white to cheaper bluer bulbs. Cheap bulbs also seem to burn up ballasts sooner as well. The few LED bulbs I've tried don't bother me much except for the color. Never thought to try one in my fridge... Maybe I'll put one in my beer fridge. Might keep my wife out of it!!!

And I am one of the odd folks, sometimes I can detect the flicker in incandescent. Not always.

I'd like to point out that the savings from preventing heat in the refrigerator are actually smaller than the savings from the lower wattage bulb.

I was going to buy a few strands of White LED lights when they went on sale after Xmas, which they didn't (Sold Out)

I want to make a simple low wattage LED light for above my computer. As much as I love my illuminated key board, when it comes time to read something, I need more light.

I dislike having the light coming from one focused area and having shadows. Hopefully by creating an array that is 3' long by 6" wide I could easily give myself the desired lighting and also have a very energy efficient 'light'
