No pic but I think that my rubbermaid isn't the biggest, and it seems that the aluminum tape increased the temperature a good amount, perhaps by as much as 15 or more degrees. The bulb I'm using is actually in the redder spectrum, and I've got a variety that I can try. I also tried a 105watt big horticultural CFL and it brought the temp to over 100F. The Trueair also plays a factor, as it doesn't move as much air as the more serious fans, but it does relatively well.
