yup, you need a uv cathode kit, the other colors are much brighter, but will not react with any UV sensitive product. If you can get two kits, one on top and one on bottom, then should get an even glow throughout the whole case. if you dont have room, one kit has two tubes, if you put the inverter in the middle, then you can put tube on top and one on bottom. (i taped my inverter in the middle on the side of one of the 3 1/2 bays so i can have a tube on top and one on the bottom.
these are the cathodes i bought:
PTS and Jab-tech have them for 5 bucks, that's the cheapest ive seen em for dual tubes.
