I saw a post in here that stated a cool tube puts out less light than other reflectors.
I tend to disagree, i can see no reason that the clear glass tube would cut down on output or spread of light. I would think that say a 20"x 24" reflector with or without a cooltube would put out the same lumens and coverage spread. I have a digital light meter and have measured the output in all areas under the light (cooltube) and can not find a really low or dead spot. What do all you cooltube users think.
