By the way, most - not all - T5NO fixtures, or more accurately the ballasts, can run T5HO lamps. Electronic ballasts effectively read the electrical characteristics of the lamp and output accordingly.
You get flexibility in your purchases and the correct lamps on hand if you do swap ballasts. T5HO ballasts will also run T5NO lamps, at a bit over the rated capacity. Not over driven to HO output though.
If you need a source of inexpensive lamps, check out your local hydroponics store. They sell more T5HO daylight lamps in a week than most fish shops will in a year. They purchase in bulk and usually sell at good prices.
