Here is an informative article on the current state light bulb efficiency. It points out that despite manufacturers claims LED’s are still behind CFLs in efficiency.
Last year Eco Brooklyn put a lot of R&D into LEDs. We build an entire brownstone floor using just LEDs assembled by us. We welded the LED to [...]
Well before you go hooking wires up to any LEDs you should first know a little about electricity. First of all there are two main forms of electricity in commercial use today.
(All of which are dangerous even if you know what you are doing. So with that in mind do not attempt to [...]
An LED driver is a self-contained power supply that has outputs matched to the electrical characteristics of your LED or array of LEDs. There are currently no industry standards, so understanding the electrical characteristics of your LED or array is critical in selecting or designing a driver circuit. Drivers should be current-regulated (deliver a consistent [...]
Being a Green Construction company in Brooklyn, NY we like to recycle, reuse and re-purpose materials. Electronics are no exception. This post is about heat sinks. LEDs like to run at about 25 deg C or 70F. Led manufacturers give guidelines for heat sink size and configuration. With this information you can re-purpose a [...]
Lighting can account for 15-20% of your monthly electric bill. With recent advances in LED technology we are able to reproduce the same level of brightness for 1/5- 1/10th the power. This is a huge savings. If we all work together we can reduce this country’s electrical draw by 10%! That equates to a lot [...]
I went to the LED light trade show a couple weeks ago. It was way cool. They are making real progress for residential LED lighting. One technology that I especially liked was phosphorescent lenses that convert blue LED into visible light like a normal bulb. This varies from normal LED lights that combine the three [...]
Here is an example of the newest recessed LED lighting. There are two shown, one with a wider width than the other. By Juno. It is not cheap, coming in at around $225 US per light. They have heat sinks to keep them cool and each unit has the transformer built in. Why they put [...]
