This question doesnt necessaraly have a TON to do with stage craft, but I think there might be a link in here somewhere. My mom has been told by her doctor that she should look into getting a "Sunbox DL" light from http://www.sunbox.com the ad she has for it says "adjustable delivery of 10,000 Lux Full spectrum Light" and not much more, but they want over $200 for it. What I would like to know is would she be just as good standing close to a theatrical light for a while everyday? They have a "research and learn" page (https://www.sunbox.com/Research/) that, to me anyway, doesnt say much. I am really wondering if this is a rip off and what comprable numbers of Lux are for theatrical lights (source 4s, source 4 zooms, and fresnels are the lights i have, but i have no idea of what bulbs are in any of them). Any ideas anyone has would be appreciated! Thanks, and who knows, i dont really mind if this turns into a discussion about lumens, lux, and other lighting measurements (yes, i read a good part of ship's 2003 post on stuff like this, but didnt understand all of it). Thanks again!
