Upgraded version of a previous project. It essentially doubles the light output, same price. Newer kind of high-efficiency LEDs from Nichia. This module runs from 18-24V DC @ 180mA.

20lm @ 50mA, 129 lm/W according to the datasheet.

Done - two more to go :-(

I spend more time cleaning the flux residue away than with soldering. I need to get solder with a nicer to clean flux core. This stuff is terrible to clean. It doesn't become hard and brittle, but stays somewhat sticky. Almost like dried coke in a laptop. ARGH.

And there was light.

Compared to the LEDs I used for the previous version (ebay, 80mA per channel), this one uses high efficient (and quite costly) ones by Nichia. 20lm per piece at just 50mA. These are sold as 'white' and are considerably warmer than the ebay ones.

Leds are almost off
