Still pricey, but cheaper.

Any other places?
Well, your ballast is electronic and can operate HPS lamps so here:
https://www.1000bulbs.com/product/57200/MHS-040093295.html
Only $31, and still CMH.
Bingo! Now I just need a daylight color one, but that's a problem for later.
If you mean 6500k, you will have to get a quartz lamp because CMH is available in the highest 4000k.
Problem is, quartz MH has bad CRI.
There is someone on here who has a prototype of a daylight 100cri QMH lamp. I think it is Trianero2012.
Can 100 CRI really be achieved? :o
yes, but unfortunately the lamp never made it to the market. It wasn't expensive or inefficient or anything which is weird.
Does he have a photo?
Yep, see here:

Maybe we should request another sample.
If you want to drop 2 grand, then that is a good idea.
In the meantime, what's the highest CRI in a MH lamp in production, and is reasonably priced?
holy mother of long extruded comment! :o
I wonder how big it can get, especially with multiple lines of text.
And what's the smallest and biggest CMH lamp ever made?
Smallest:
20w


Largest: Philips Allstart 860w.


Why not make them bigger or smaller? Why not a 5mm LED sized CMH?
A 20w arctube is around the same size but if you mean a complete lamp that is not possible. Here is the 20w lamp next to ED17 and ED28 lamps:

But are you really sure? There are incandescents the size of a 3mm LED.

I like my lamps thick, my ballasts heavy, and my fixtures tough.
