This 315W CMH lamp is indeed being run on a LFSW ballast in that very pic.
This ballast;
LEC - Light-Emitting Ceramic
- Thread starter potroastV2
- Start date

The 860W CDM Allstart lamp is designed to run on a magnetic ballast, which makes it much less efficient than otherwise similar 315W CMH lamps on LFSW ballasts. Some friends have been doing some testing with the 860W Allstart on 1kW LFSW ballasts and they report that it works great and is much brighter than when on a mag. No quantifiable data as yet.

Mine are open rated. They have two little quartz cylinders inside to contain the pit if it pops.

At about adjustable led's and use the oval?

Yea, this first time I ever seen a moguled 315w w/o an adapter would have thought it to be a MH without their information

I don't understand your question?

That's what convinced me to get them!
You could still use the oval screens if your led's were capable of tilting.

Oval screens? I'm missing something here, lol
I mean the cylindrical screens

If we're talking about COB LED lighting, my fixtures all use glass lenses.
I confess to having no idea what you're referring to here, I'm sorry?
Lol, I am referring to the half cylinder screen you train your plants to. If your led's were adjustable you could still use them

I AM still using them; I merely bent them flat!
A compact four or five sided box with COB LED lights on the outside, fans, fins and drivers on the inside, could emulate omnidirectional lighting reasonably well.
But why? Silos don't fit well in square rooms. They don't save much space in terms of the overall footprint. They sure aren't easy for someone to get inside and work, they're too cramped.
My conclusion then is that the old cylindrical shape, made necessary by the nature of the lighting it was designed for, will be as obsolete as those very same lights and the attempt to cram a square (directional) COB back into a round hole is a fruitless exercise.

LOLOLOLOL OMG I started out with those! With the silly little bag of nutes and everything!Dr. Jeffery DeMarco would be proud of you!
Hint: Phototron.
The COB LED device I was describing would look much more like 'Nomad' from the original Star Trek series... another blast from the past, lol
So hope you guy don't mind me jumping in on this forum mix... Been trying to do some serious info diggin on the 315w CMHs and the info is a little all over the place, like anything else on growing.
I currently run 4x8 tents, just two at the moment. one with 2x 600w sunpule 3k lamps, and other with 1 3k sunpule 600w and one hrtilux 600w blue, and each has a 80w hanz panel led mixed in the middle, 8 plants per tent in 10-15gal pots of supersoil style dirts and a compost tea here and there. Quality is great, but id like to improve lighting if worth it to lower electric or heat, but not lose weight. Id like to be same if not more weight.
My thoughts was trying 2 315w (either sunlights or hydrofarms models, i like hydrofarm is both 120/240v) and mixing in a hanz panel 150w led in middle in each tent as many claiming each 315w near 600w and most people claim the sunpule produces less than 600w hps. What are your thoughts? will i lose yeild?

I think lots of growers are starting to agree that 315W CMH lights are worth about 500W of HPS or MH. Spectrum output is fantastic and they don't heat up the space nearly as much.
I can personally attest to the fact that they also do veg brilliantly.

What I like and has been mentioned here a few times is LEC's penetration compaired to cobs.
+1 for LEC there
Both are fun toys though
