I talked to a club member about LED lights and how much money they saved in electricity. But he said he stocked up on incandescent lights before they were banned so he could have them for his radio room. He has had problems with LED lights causing RF interference with his radios, so he went

Quantsuff emailed us a link about a new material summarized at Newscientist.com. I have a few thoughts that I’d like to add. The stuff should be great for illumination. But I have doubts about its use for display purposes. Displays have millions of very small pixels. If one or a few get contaminated with dust

I do exercise, but when I’m reading couch potato style, I like to have my LED lights with a switch close by. So I make up extension cords with a plug, switch and outlet socket. I also like to put the on/off switch where the AC power comes into the adapter because there will be

I got another email from Designing With LEDs about removing the fluorescent lights from a bathroom and replacing them with Cree LED lights. The blog shows the charts from a spectrometer showing the difference between the fluo lights, which are deficient in the red, and the high CRI LED lights which have much better lighting

QS sent this link to me about Osram’s smart LED light called Lightify. I went and browsed the shelves at Fry’s Electronics. They have the dimmer sockets and remotes on the shelf that use Sky Link.
I got some 1 watt LEDs from Goldmine Electronics for 5 for $10 (They were on sale when I bought them). These are LEDs that do not have a mounting bracket, but were made for surface mounting. I’m not sure if the case itself is supposed to be held to the PC board only by

I have made an assortment of LED task lights that I’ve clipped onto places where I need a small, low power light, such as my keyboard, workbench and kitchen counter. They typically have 3 or 4 LEDs and run off an AC adapter of about 5 volts. I want to make a lamp with multiple

LED bulb prices are still coming down, but the general public is still not aware of the advantages and still think the prices are too high. And the public is still unaware of the long term savings in electricity from which they’ll benefit. I still see 60 and 75 watt incandescents in dollar stores, which

I found some soda straws that are thin and about the same color blue as the blue LEDs I got from goldmine-elec.com. I got the idea of using a soda straw from Quantsuff at quantsuff.com. He used two white LEDs in the ends of a short length of white translucent (semitransparent) soda straw to give

I was asked to fix a Himalayan rock salt crystal light to make it brighter. These lights are larger (and heavier) than a 1 liter bottle. The salt is kind of a rusty red due to iron dissolved in the salt. There are many examples of these if you search for Himalayan salt light. The
