CFLs May be bad for your Health

Inspired by a European study, a team of Stony Brook University researchers looked into the potential impact of healthy human skin tissue (in vitro) being exposed to ultraviolet rays emitted from compact fluorescent light (CFL) bulbs. The results, “The Effects of UV Emission from CFL Exposure on Human Dermal Fibroblasts and Keratinocytes in Vitro,” were published in the June issue of the journal of Photochemistry and Photobiology.

“Despite their large energy savings, consumers should be careful when using compact fluorescent light bulbs,” said Professor Rafailovich. “Our research shows that it is best to avoid using them at close distances and that they are safest when placed behind an additional glass cover.”

Oops! We are using them in our desk lamps.
I do wonder if really cheap ones are worse than more expensive ones. Many of ours were bought at a heavy discount.

My LED Lamps

I recently changed out our light bulbs to CFLs. At least those inside the house. Then my son gave me four (4) LED lights for Christmas! They are supposedly 60 watt equivalents; so were the CFLs. But the actual light is measured in lumens. The incandescents were rated at 800 or so lumens. Those marked “long life” yield much less light which is why they last longer. The CFLs I had were discount bulbs and were 50 watt equivalents, using 11 watts; they were rated at 800 lumens.

And they worked good if you don’t mind the brief hesitation when they start and the several minutes before they reach full light. OTOH, the LED has a second or two pause before they come on but start at full brightness.

The CFL is almost the same size as a standard light bulb but the LED is noticeably longer. And heavier. Most of the length is NOT the lighting portion; the electronics are in the metal base.

So we changed out two kitchen lamps to the LEDs which barely fit in the fixture.

The difference was stunning in how bright the kitchen was! The rated lumens are about the same but the LED light is MUCH brighter! So much that we decided NOT to put them in our reading lamps. All I can figure is that most of the light from the LED bulb is directed downward while the other bulbs are more multidirectional. Lighting the ceiling is not a big priority for us. Lol.

There is not much difference between the CFL and the LED in watts but much difference in the light created.

Anyway, I used two of the LEDs in the kitchen and eventually one for the front porch light. That one doesn’t light the yard as much but our porch is brighter!

Since I really just replaced two CFLs with the LEDs and the front porch incandescent with an LED, the net savings was 44.5 watts. But these are lights we use a lot so there will be a lot of watt-hours of saving.

And one of the best parts is the 5 year warranty! Thanks, Scott.
