I bought one form HD also.
I use a strip outlet. It has 8 plugs. 4 that are just constant power, and 4 that are on a timer. it has like 8 different timing on it (which obciously you dont need for lighting) But i like it much better than anything else i've had. Its like 25 bucks or something of that nature.
I use one on my fish tanks as well. Lighting is on the timers, filters, circulator and heaters are on the constant. Makes things nice. It give you a little extra length too. Light fixtures usually dont have that long of power supply, so the extra 2 feet it gives is a nice bonus
