Incandescent light bulb replacements

Page 3 of 3  


In corncobs style there are no electronic parts that shake loose. Those other LEDs using voltage converters and current regulators, bigger parts can fatigue over time, also in cfl circuits.
I was just checking out led display at home depot. Pretty cool. Cool white, warm white. Some of the large aluminum fins do get warm. Bright !

Have had several "decorative" LED lights give up the ghost, haven't lasted any longer than the incandescents or CFLs that they replaced. So you're right, they can screw up almost anything. Had a couple dead out of the packages, too. Since all of the current lights, no matter what type, are the products of that great Chinese QC, it's no wonder. The LED bulb failures were total, not just a few defective individual LEDs croaking like on a cheap flashlight. And this is with a stationary floor lamp, not on any sort of vibrating tool. At least the dead ones don't have any mercury.

A study by UC Irvine's Department of Population Health & Disease Prevention has discovered that LED diodes contain unsafe levels of carcinogenic toxins. While LED's less energy friendly cousin's, CFLs, contain a measured amount of mercury, LEDs are laden with lead, arsenic and a handful of other chemicals that have been linked to different cancers, neurological damage, kidney disease, hypertension, skin rashes and other serious illnesses. Not only are these chemicals harmful to consumers if the bulbs are mishandled or broken, but extracting those toxins from the earth is a destructive process.

Is there a link to the actual study anywhere? All I can find is stories based on a press release that may or may not have any relation to the content of the paper. The same press release goes on about the copper content like the copper contend of LEDs is going to end the world, so it has to be taken with a huge dose of salt.

And ALL of the "hazardous" material is totally encapsulated in the plasic "dome" of most LEDs.

I can't remember where, probably here. I've heard the Chinese made LED corn cob lights have a high failure rate.

It would have to be a really crappy LED design to _not_ stand up to vibration better than an incandescent or fluorescent. No little thin wires, nothing working at high temperature, everything well supported, vibration resistance should be much better. However I have great confidence in the ability of industry to screw up a simple design.

They are just like Christmas strings, all in series.

If you are comparing them to a 150 watt par38, or 150 watt R-40 flood, which are typical style lamps for large recessed down lights, you'd be incorrect about the light output. Of course, both these types of lamp are no longer available in 150 watts, in an incandescent type, but when they were, either type delivered over 2000 lumens compared to the approximately 800 produced by the LED. Par's and R's also direct the light downward unlike an "A" lamp.
