Now here is a weird question.. I was reading the paper this morning and there is a whole new generation of grow lights. I had no idea there was an old generation. One of them is a treated, florescent, high intensity bulb. It is blanced blue to help plants grow. There is also one balanced red I think. The blue is probably balanced to daylight since blue is historically what is added to incandescant lights to make daylight color. So the question is has anyone tried to shoot photographs under this light source. I would be curious to know what they look like but I shoot very little color. By the way: if the color was good with them, and the intensity is high, you wont have the heat problem you have with solid lights. Since florescent barely heats at all you could use them easily in a studio. Constant light is easier to work with since it is wysiwyg lighting. So if you haven't tried it, someone should break down and buy a bulb and see what it does. I would be curious even though I have no intention of shoot studio portraits at the moment.
