Ssa has one point, at low lux levels you can't see color, even at high cri.
Using headlamps for painting, it is possible to get any corded light looking dim, unless you use over 80k lumen hid lights. The Hotspot Corona can be close to rod and cones overlay of vision-so a headlamp has a huge leg up over a flood corded light, as photons are pointed only to current viewing area. At higher currents, outside colors. Though not sure the premium value over a 80cri xpl 4300k, or nichia, for average person-which I am not. I chase lumens, precisely because I can see colors better at higher lumance. Color for eyeballs is cri, gai, and luminance. My camera mainly likes cri. I am still trying to figure out how to weight these. Give me a 65cri 400 watt metal halide any day for painting, over a 500 watt halogen - the color perception contest isn't even close.
I would only buy, if a light engine I could use off two 18650s. Or if they made it in a good right angle design. Yeah probably $60-$100 is my limit, since I can make my own 374 lumen xpl v6 neutral 2s8650 186lpw infinitely variable 8h40 minutes minimum runtime headlamp for $35 to $40 and a few hours. I also may be turned off if the lpw were too low.
