Gives alot of light, can be used to embed into any project. Can be used with an arduino and a NPN transistor (i used a P2N2222A) to dim the led using PWM or use a standard digital pin to make it work as a on/off switch. No documentation, no resistor values given (would be good to know it in advance) ... Read more
Very good light. Very bright and white.
Very less consumption (My calculation: 2.6W, 12v, 0.22 A).
Will need a radiator for the heat, although it is not very high, it is heavily recommended. Slightly overprice.
Needs a cover to be protected. I use it in combination with: http://dx.com/p/ac-to-dc-voltage-... Read more
Very bright. Nice color rendering. But color temperature not 6000K. It closer to 4100-5000k. But this are even better.
Aluminium alloy PCB, that allows easy cooling.
Low heat. So radiator size can be small. I use 5x12cm U-shaped aluminium plate. It also used as reflector.
There are easy to read marks ... Read more
