Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month Pros: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. Cons:No documentation, no resistor value... Read more

Involvement:General (knows how to use it) - Ownership:1 day to 1 week Pros: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. Cons:Slightly overprice. Needs a cover to be protected. OtherThoughts:I use it in... Read more

Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month Pros: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 a... Read more
