I was looking for some inexpensive lighting options and while at Home Depot I found a 48" dual 54 watt bulb T5 HO fixture for $40.It was posted as a new procuct. I bought 2 and now have 216 watts for my 100 gal tank for 80 bucks plus the cost of the bulbs. You have to wire and custom mount them in your hood but it was worth the extra trouble for that cost.
