Tungsten
I haven't used tungsten lights since the 60's. My church however, was getting rid of case sets of Lowel DPs and Lowel Omni lights. I couldn't pass them up. 1000 watts is very hot and very bright and that's a good thing since my studio tends to be cold in the winter. Light is light and all I do is move lights around until I match the image I have in my head. It is actually easier than strobes since what you see is what you get. No chimping needed. I have LED video lights but they don't keep my studio warm. They also are no where as bright as these Lowel lights. I may use them for video as well. Seeing how these lights have fallen out of fashion since LEDs have arrived, they are probably pretty cheap (mine were free) and bright. I think that I will go back to strobes when summer comes but they are perfect right now and for the next 4-5 months!
