EBAY METAL HALIDE BULB

[The Grizz]

There is another seller from Canada called Hobby Light's. If you want a good example of how good these bulbs are just look at Dez's tank, he only uses the cheaper Chinese bulbs from what I read on his threads. I have never had a bulb dim after a few months and even if you change them every 6 months you are still ahead of the game as far as $$$ go.

EDIT: here is the link to Hobby Lights Online store
