it looks like it's here.

The CMH vertical bulb … check it out …

I am so happy that this bulb has come out as, I don't have to stack multiple 315 CMH watt bulbs, and have many more ballasts than just one per vertical drop now.

Just have to find the correct ballast to run this new bulb.

What I'm wondering about is working around these bulbs?
They appear to be a single Jacket.
where philips CMH 315 in available in T-5 Single and rated for a sealed fixture.
And the T-12 thats a double jacket, rated for open fixture use.

That is a mogul based bulb. The 315 has a different base and only runs on a low frequency square wave ballast.

Yours seems to be like the old 850's (?) and 400's that run on the old ballasts.

Does it say what ballast to use?

When I searched the bulb only a new double ended digilamp 945 came up front.

I think the manufacturers are going the wrong way just like some led manu's. One advantage of 315 watt lights is better light distribution over 1000 watters.

Sunplix makes a digital that will run this lamp at LFSW but I'm not a fan of sunplix much anymore and would say a hortilux platinum would run that lamp nicely .
A few companies are pushing a uhf sine wave digital with a really clean signal , very low thd is the key to not shaking this lamp to pieces.
Solistek is one.

No I didn’t.

I have gone with 630 watt de CMH lights positioned horizontally over my garden.

If you are interested in vertical lights did you know of these …

I guess this solves the temperature and safety issues.

Now, is it better than LED?

Having worked in solid and on flat vertical panels, I'm gonna say, 'no'.

But by all means give it a shot! I'd suggest running the 6/750W DE instead of the big one.
