Right. The T5 lights used for growing are HO (high output) and bOnger is correct on the wattage/lumens (for the HO bulbs). The bulbs that HD sells are not HO (at least not that I've seen). Also, if I recall correctly, unlike both T12 and T8 bulbs, T5 bulbs are measured in metric lengths. So the 2 foot bulb at home depot is probably more like 21".

T5 bulbs cannot be retrofitted into a T12 fixture, and I don't believe they can be retrofitted into a T8 fixture either, though I'm not sure on that.
