Found this from another site from these guys here for 5 bucks a pop and very cheap shipping. It's seems good for a lazy DIYfer(me) I'm thinking 2 of these in my 2 ft 40g tank and 3 for my 48" tank downstairs..... it seems a little bright from the look of the picture but maybe if I use a variable power supply I can dim it to my liking? There's a 24bulbs and a 3bulbs version... 3bulbs is probably best match....
There are also these other ones they is probably good too since it's screw on type vs. stick on as the above... and they comes 2 to a set.
