Joule Thief (3 Light test) 019

Joule Thief Test to check the differences between a 3v incandescent bulb an Led and a Joule Thief Based LED..

The incandescent bulb sucked.

The LED just on Normal worked OK and would easily out shine the incandescent bulb.

But the Joule thief circuit Was Brighter and I am guessing will last much longer.

They all had fresh batteries put in them at the start of the test and I might just leave them running to see for myself which is best. I will post the results if I do.

Enjoy…

Paul.

LED light bulbs cost $40 a light bulb and last for years. They have no mercury in them. CFL’s are $3 each and last for years as well. CFL’s are still recommended over the traditional light bulb. Yes it contains mercury, so dispose of them carefully. Check your city and they will tell you how.

LEDtronics, Vincent Thomas Bridge Lighting Ceremony part 2

Pervaiz Lodhie of LEDtronics proposed the innovative idea of implementing solar-energy in tandem with the LED lights. A 4.5-kilowatt solar-panel system located near the bridge generates electricity that is then sold to the Los Angeles Department of Water and Power. While the LED lights themselves do not directly tap into the solar-generated power, the Vincent Thomas Bridge is the first of its kind to leverage solar-generated power to pay for the cost of operating decorative lighting. A total of 160 LED fixtures light both sides of the bridge, 80 LEDtronics units affixed to the apex of the suspension cables along with an additional 80 located at deck level. Each LED fixture consumes only 19.5 Watts of power, making LEDs the perfect complement to solar energy. Several variations of LED lamps were tested before the solar-powered, environmentally friendly Blue 360-LED lamp received the go-ahead. Blue was chosen because it would standout amid the amber-colored lights and maritime navigation indicators in the Los Angeles Harbor.
