LED Panel
I propose we make an LED panel for the UV box. A guy from PTL is doing the same thing (UV Box for DNA analysis), and Sasha is interested in making a white LED panel.
The panels, when bought online, cost a lot due to their large size and weight (shipping costs), but it would be fairly cheap to build them ourselves.
Here are some pics of the way they are made:

Case study
Component:
- UV LED 5mm
- Forward voltage: 3.2 - 3.4 V
- Max. current: 20 mA
- Angle: about 25°
Power supply:
- Voltage : 20 V
- Power: ? W
Dimensions:
- Space between LEDs: ~2.5 cm
- Space between LEDs and PCB : ~6 cm
- Average PDB size: 10 cm x 16 cm
- Max PCB size: 15 cm x 25 cm
