No Bulbs - I ripped the 110V stuff out. I am just using the Covers as a heat collectors - yes I circulate the air through the 'tunnels' with 12V fans on opposing ends. Essentially the air is being moved up one side and down another - and then into the large chamber. When the sun is shining, I can realize a 50 - 70 degree rise. I've seen temperatures in excess of 165 deg.

Is it just as effective?
