Q: 1. Can this be used with the chimera pancake softboxes?

A: Yes, as long as your Tota lamp doesn't exceed the rating of 1500 watts. For any softbox, you absolutely must check the manufacturer's watt ratings. Lowell Totas typically use lamps at 500, 750, or 1,000 watts -- far too hot for most softboxes.Many softboxes are rated only for strobes or for flourescent lights, With these boxes, Tota lights present a serious fire hazard. Even if you're within the maximum rating, remove the inner fabric diffuser, open the vents, turn your lights off at every opportunity, and keep a fire extinguisher nearby.

Q: 10. What's the CRI ?

A: In addition to the answer already here, the higher the number the better the light on the CRI value. This light is supposed to have a 90 or greater CRI value. I've seen several spec sheets that claim 93 and some 95 . Generally a high end and well-calibrated spectrometer is the only way to know for sure with each light that you own. At this price point, I'd go for the 90 value in terms of guessing;-) They are nice lights though, especially for dollars expended.
