CHM PAR flood

Another GE Constant-Color ceramic halide lamp here. This is a 35W CMH PAR20 lamp. It does have a quality of light that could be easily use as a tungsten halogen replacement. The spectrum has a nice spread of emissions across the visible range.

I agree, those lamps have a really nice light color. However, for the first version of the CMH/CDM technology with a dysprosium-based fill chemistry, I wouldn't say that their /830 color is indistinguishable from that of incandescent lamps, but the gap is certainly much smaller in the case of later cerium-filled /930 lamps.

I believe we have a Philips version of this somewhere, not sure, will have to dig.
