esshup, thanks for giving that first hand experience. I can't tell much difference between the specs of the $300 model from the $75 model listed for 1.5 acres. I can see that the $300 model has 3 bulbs and the $75 has 2 bulbs. I see replacement bulbs for the $300 are about $30 each x 3 (14" long bulb 40w) and the $75 are about $14 x 2 bulbs (12" long looks identical, 40w).

Since they hang outside, a good warranty and easy way to get replaced under warranty, even locally would be important.

Did your clients use them over a pond to feed fish or just to clear bugs from their yards?

I'd like to try one and see if I can find a way for the bugs to not be in the collector but be falling freely into the pond.
