I'm really curious how this unit works for you guys. I built a couple of units like this myself two years ago. Did some experimenting and found that if I wanted to consistently knock bugs into the water I had to use a 3000 rpm motor I think. In order to get a diameter large enough to hit many bugs it ended up being about 1/10 or 1/8 HP (>75 watts) and 18 inch diameter. In order to get enough light I ended up with two of the circular flourescent bulbs that are probably about 30 watts combined. I've seen this stock unit before and wondered if it has the size and power to really collect some food and if so I can't believe it would run long on batteries. The ones I built cost about $40-$50 for parts and a couple hours time and they knock bugs into the water by the thousands.
