Is there any way to verify if the EBAY CHINA LED house bulbs use only safe radiation?
Do you use any LED light bulbs in your house ?
I noticed that EBAY sells many different LED house light bulbs that are directly shipped from China at a very cheap total price ( do an EBAY product search of "E27 LED 110 VAC bulb" ).
Do you think that there is a concern that any of these China LED E-27 size house light bulbs may not all be using only healthy LED's, such as using some LED elements's that put out too much infrared or something-else-dangerous radiation ( even if the EBAY ad says that the LED bulb is all completely safe ) ?
Is there any way to verify ( after one has received their China LED order in the mail ) if these EBAY CHINA LED E27 house light bulbs are using only safe light radiation LED's, and not any LED's that have any harmful and unsafe radiation ?
If these LED bulbs are safe, then they pay for themselves very quickly, when one considers the great cost savings from just the amount of electricity that is used. And then there is also the convenience that they don't break easily, and they last a very long long long time.
If anyone is considering ordering any of these LED's, then be very careful about the voltage as many of the EBAY ads say only 220 VAC. But some give a range of voltages for example such as from 50 to 240 VAC, which is better.
Dangerous radiation. Huh.
Are you sure you want to mess with something this complicated?
"Lossy Traps, Oh my!"
"Supporting AMSAT-NA Fox-1 Cubesat Launch in 2013!"
I think there is something missing when claiming a big power cost saving.
Only if you run it a LOT.
None of the tungsten lamps in my house are on often, for for very long. The payback period would exceed mine.

Now there is an invention sun tanning LED lights! Keep that nice glow throughtout the winter! You can get various glass filters and measure with a light meter. I have a light meter I bought off Ebay for $100 or so that I use to measure light for solar cells. Then you can get different materials that pass the frequency you want to look for. We did some playing around with IR photography and filter for that.

Knowlege can overcome fear. Learn and research the subject and you will be able to answer your own questions. However if all your information is coming from the internet be sure you learn to able the proper 'filters' to try and seperate facts from myths.
It's the UV that is bad for you -- not the IR. Since UV LEDs are a bit more spendy than regular ones, I doubt they'd put them in the fixtures.
I think the white leds start out as UV which excites a phosphor. ??

I find the 3rd hand I've grown since I started using LED's to be really, really handy, particuarly during contests.

Individual LEDs are uniform in their light spectrum output, as they are in intended color range.. Thus only one LED of an individual type need be tested for possible harmful radiation levels. Once that is accomplished, many production runs of the same LEDs may be deemed safe for normal usage.
Any light source radiates light...I kid you not...because light, like radio, is an electromagnetic radiation that travels at the speed of radio waves. At night it is usually dark when there are no lights on...Durrr...
Very high light levels may be dangerous to your eyes.
