Light Bulb Efficiency Update

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 [...]

LED lighting is (almost) there

Here is an interesting cost comparison between LED, CFL and incandescent. I have not checked the numbers but they seem pretty accurate. They clearly show that over the life of the bulb it makes a lot of sense to buy LED.

What the numbers do not show are the quality. I’ve tried a lot of [...]

AC/DC the shocking difference

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 [...]

LED drivers

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 [...]

LED basics for beginners

Here are some beginner to intermediate level projects. These are fun things you can do with LEDs while you learn about the technology and its uses…Plus its productive! Also remember, you do this at your own risk. (but I don’t know anyone that has started a fire with 5v. Survival situations don’t count.)

This [...]

LED Technology for the Next Generation

LED Lighting is an important design issue that we take into consideration, importantly due to being a green builder leading sustainable construction practices in Brooklyn we have to stay on top of new technology. In short to ‘build it forward’ is not just a catch phrase it is a feeling and belief in resourcefulness [...]

LED heatsinking

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 [...]

Pentagon starts using LED Lighting

In a press release from Jan 2009 it is stated that the pentagon is installing more than 4,200 recessed LED luminaries in Wedge 5.They are expecting a payback of less than four years with a reduction of 22% in overall electricity usage. A total reduction of 140 tons of CO2 per year. They even found [...]

LED heat sink and power supply salvage

So with the understanding that any experiment should be undertaken with the proper materials. I set out and found a large supply of computers and harvested anything I could use, before they were sent off to be melted down. (Or crushed) After 7 hours of unscrewing, unclipping and moderate finger jabbing I end up with [...]

LED Basics

LED lighting is not a new idea. It is only in the last few years or so that the technology’s efficiency and efficacy surpassed CFL and HID lighting. This makes it hard to find cost effective lighting replacement, without large upfront cost. But at Eco Brooklyn we are passionate about improving the energy efficiency of [...]

Lighting with LED 1

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 [...]

LED light tradeshow

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 [...]
