I build and set up a box, seperated in 4 sections. Each section containing one 1 Watt LED to support the inhabitants with light. The boxes have fans, so the air inside will be interchanged from time to time. To control the amount and - for the first experiment - the duration of the light and the fans i wrote a little script that is running on an arduino. This script also counts the time (and in case of a powerdrain stores this information on the eeprom). The LED are suspended from the top of the box using some bend metal strips, which simply clamp the star platine of the leds in place. Therefor i was able to adjust the space between LED and Pots to my liking, plus i didn't have to use any additional heatsink, as the LED were completely surrounded by air. | I build and set up a box, seperated in 4 sections.
