4,000k or above 20watt CMH lamps? « on: July 11, 2017, 08:43:10 AM » Author: suzukir122
I have 3,000k 20watt GE CMH lamps for my track lighting... but I was wondering, is there different color temps, preferably 4,000k or above versions of them?

Common colors for CMH lamps, are 3000K and 4000K. The only daylight color CMH lamp I'm aware of, is EYE Cera Arc 5500K . Also, EYE Iwasaki, producing a wide range of color temperatures for CMH lamps, including pastel colors: https://www.eye.co.jp/lighting/sources/ceramic/

Ahh so the metal halide lamps that have a slight blue tinge to them are typically 4,000k? Sailormoon_01_uk has a pic of the exact lamp used for 3 of my metal halide track lights I'm hoping to try and find a GE 20 watt CMH-T lamp that has a 4,000k color temp rating. (or a little higher). I've looked around for a while and can't seem to find any... only the 3,000k ones.

4000K CMH lamp, looks neutral white without any blue tinge. I've seen 840 CMH lamps here in Israel.

I'm likely looking for something more 5,000k or up to 6,500k in color temp then, although 4,000k isn't out of the question.

CMH lamps higher than 4000K are rarity. The EYE Cera Arc 5500K, is the only high color temperature CMH lamp I'm aware of.

Geez. That sucks. 20watt CMH lamps are absolutely awesome, and very very bright despite how small they are, so I was hoping there was more variety of options regarding color temperatures. Are there any other companies that make the 20 watt CMH-T lamps besides GE?

Quote from: Ash on July 11, 2017, 02:04:35 PM If you look in the specs of higher power CMH's, you'll see that generally the 3000K ones are more efficient. Looks like it comes down to the Halides responsible for the warm part of the spectrum being better behaving. The 20W lamp is hard enough to make as it is, perhaps they couldnt get the "bad" Halides to work well there at all It is quite simple: The "warm color" part is the sodium, which is easier to work with at these low wattages (inherently more efficient, because it does not need that high plasma temperatures, so less thermal losses). So fro the higher CCT more portion of the light can not be generated by the sodium, so less efficacy...
