Frank, I will definitely buy that charge controller. Thanks for the tip. As for the white LED drawing bugs or what color, I just dont know. Some or most bug whackers/zappers use flourescent, I was thinking of a DC flourescent. Some lanterns have them. I know that LEDs are very pure in the one color they give off. You may do some testing at your pond, I have many projects going at mine and it is a long way off. Please update this thread with progress and I will do the same, hope others will join in.
