Well, cheap is out the window but check out where I am so far. I found out my dad has a brand new husky 400watt power inverter out at the land so today I built the light and the 20 watt solar panel will be the last step. I am going to go ahead and install the light over the water and use a charge from the wall for fishing for now and I hope to have the system connected to a solar panel in a month. I am using a 13 watt 2700 kelvin cfl for the infared bugs and a slightly stronger 19 watt 6500 kelvin for the UV blue spectrum. I will run the rig for 4 hours each night on a timer so the wattage draw will be 128 watts and with a 20 watt solar panel on the average day I will charge back in about 200 watts. I will be upgrading the inverter to a husky 750 watt inverter for $85 later but the 400 should get me by for a while. I am not a good electrician or carpenter but the rig is sound:)
