Robert Park wrote asking about the GE "Sunshine" bulbs at home depot. They cost about $6. If you look at the tube, you'll see they are just a repackaging of our old friend the Chroma-50, which is a tri-phosphor 5000K balanced tube with reasonable CRI (somewhere between a cool white and a Vitalite). I say, go for it! - Erik --- Erik Olson eriko at wrq_com
