That's a pretty small reflector. IME That type of reflector tends to focus the light, giving a more intense, tighter pattern than a wider reflector with a flatter top. They are more suited to a multiple lamp setup. The real advantage to them is that the smaller interior volume makes them very easy to cool, in a string. They flow air nearly as well as a cool-tube, but offer more control of the light. Adjusting the bulb position within the reflector may help some, but it won't give the more even coverage of a larger unit.

Have you tried moving the bulb at all? That's really the only suggestion I have to offer.

Hope somebody else has something more helpful for ya!

It's got an EasyCool 6" reflector... check it: Hi-Tech Garden Supply Also, the light is currently only like 15-18" over the tops (12" for the crazy stretcher). Should it be raised to 24" or so to get greater coverage? I was under the impression a 1000W would cover a 5' x 5' easily. Rating: 5
