Yes, but one tube alone won't be enough for corals.

Yes, if it's 80 watts, it's high output (HO). They make them in both standard output and HO but the 80 watt 5-ft size (actually it's 57.606" long) is high output. The HO T5 puts out about 1.7 times the lumens of a standard output T5 and nearly twice the lumens of a standard output T8.

With T5's, it is very important that each tube have a separate individual reflector because this maximizes the efficiency of the lamp, directing more light downward into the tank.

If the lighting is for a fish-only tank, you could get by with as few as two of these HO T5's but if it's for a reef tank, you will probably want at least six of them. Something like four 10,000K and two actinic would be nice.
