Do you guys think with T5 LED tubes like this can be made into a 6 or 8 bulb fixture ?
:idea:

Yes, you could make a fixture with as many bulbs as you wanted. Looks like they have their own reflective surface. You won't need a ballast as they are 12 Volts DC. So an appropiate 12 V power source is all that is needed. (depending on the amt of bulbs you use)
But, do you really want a 6000- 7000 degrees Kelvin bulb for a saltwater tank?
Thats really good for a planted freshwater, but saltwater should be between 10,000 to 20,000 depending on your preference

Wouldn't use them for corals, the LEDs won't be powerful enough for most corals. You want something that uses 3W LEDs or at least 1W.

i have 3 of them on order-should be in next week-that i am using on my plankton reactors.i'll test the par on them-but i agree that you would need a 3 watt system
