hey great job, i still use those in my sump, and i am planning to use them, although i went on the LED road for my DT, and got 108 cree's for my 150 build, i still think that there is a good market and placement for xenon lights, in the sumps or nanos for example, they are way cheaper than leds, cheaper than MH and use little wattage, (30, 55) and what i think is the best feature, they are waterproof, so they are perfect for the sump...
like jski711 said, show us some pics with the lights on, also what color temperature are they...
