We have quite a few very talented and dedicated artists here in Texas. One of whom is Austin artist, Qiang Huang. http://qiang-huang.blogspot.com I would like to share a tip that he was kind enough to share at a recent demo. He spoke of having to paint at night which, as you well know, does not provide optimum lighting conditions. So, he set out to create his own "north light". He told us of a small halogen flood light at Home Depot and emphasized to look for the one with the blue dot in the center. Needless to say, I visited HD the very next day. What I found was a 50w, indoor/outdoor Par20 Flood, Natural Light Plus, bulb by Philips. It costs about $8 and fits in a standard size socket. This is THE bulb to get. Thanks Qiang!
