Hey guys I know there are like a million treads on this subject but I was hoping to get some good quick answers and talk back and forth so I started a new one. I need to build an exposure box. I am planning on buying a replacement vacuum blanket for the top and using a medical vacuum pump I have handy. But as for the light source I think I am going to use B L tubes because it’s what I learned on. I know that Metal Halogens get the best detail and all but I know even less about those. I am still looking for good detail with the Black Light tube set up. Here’s the thing, how do I know what are good lights to use? What is it you look for? Strength rating, wattages ex. Obviously I am looking for non-filtered black lights and have been told that these are good, $7.78 F20T12BL 20W T12 24" BLACK LIGHT F20T12/BL INDUSTRIAL but I want to be able to know at an glance what I am getting. Thank you for any help.
