another 10g light question.

Except for 8 watt tubes being only 12 inches (or so) long, this one looks a lot better than the other 8 watt fixtures I've seen.

you are right, for got about the length of the bulb. any cheap fixture out there has 18" bulbs?

Putting a T5 light on a standard 10 gallon tank is a waste of money. Even one T5HO bulb is way too much light, and I don't think there are any one bulb T5NO fixtures, but that would be borderline too much if there were one. To use these lights you need to suspend them quite a ways above the tank, perhaps 10 inches above the tank for a T5HO.

Why not just use cheap T8 light strips, two bulbs will give medium light?

Thats what I was looking for originally but all the hood for 10g only has single bulb, perhaps I wasn't looking at the right places.

Use 2 of them over a glass or open tank.

Alot of people are using spiral CFL lights on ten gallons with good results. Cheapo desk lamps are the only fixtures you would need.
