If you need to more light to heat your space, surely you'll need to put a heater in there for lights out.

They're advertising that it serves a few, including a 860w CMH bulb I've never heard of. https://www.sunspectra.com/product/1000w-dimmable-cmh-ballast-remote/

Ya, I figure that's the case too. Personally I think it's strange for manufacturers to put out a new product without have test data to back it up. Strange business model.

For what it's worth, I emailed SunSpectra, who makes a ballast that potentially could work for the 945w CMH de bulb, to ask to point me toward anyone with growing experience with their ballast and that bulb combination. My question... "I'm in the market for a 945w DE CMH light and your 1000w...

Well, I guess there is at least one LFSW 1000w ballast on the market... https://www.sunspectra.com/product/1000w-dimmable-cmh-ballast-remote/

True, I haven't seen that. I wish they made a standalone ballast to use with an acde hood (or any other hood).

I don't get why a bulb manufacturer or brand would put a new type of bulb out, such as the 945w de cmh, without coordinating with a few growers to post the results. They don't post the spectrum either.

There already are 945w de cmh bulbs on the market. It's my impression that there aren't any matching low frequency square wave ballasts (if that's even important). I can't find a single user experience. Obviously 945 and 1000 are effecrively the same power.

I guess therin lies the difference in our assumptions. When I was looking all around for needs and specs to build one a couple of months ago, nowhere did I find evidence that 9 COBs could serve a 5x5 scrog all that well. I was looking at closer to 20 cbxs at over $1k. I didn't want to build a...

I've been trying to find a good CMH option for my situation but haven't yet. I flower in a 5x5 scrog and short of putting 4x315s in there, plus some AC, I just don't see an option. The 630s don't have that kind of footprint and the 315s are like a 3x3 flowering footprint. I did see they have...

Seems a little premature to say HPS is dead when you haven't had a harvest off of your new lights. I'm sure they're great and all but let's be level headed.

I don't understand your reply.

A COB LED setup that would serve the same space as an 1k in a ACDE would cost twice that, how do you figure LEDs are a better buy? $100 bulb replacement every 2 years (if it's just a flower tent light...10k/12/365) makes for a long payback period on the LEDs, unless your electricity is...

While I don't have experience with HID, I'm under the impression that this fixture (below) would make a 1000de work just fine in a standard tent. https://www.sunlightsupply.com/shop/bycategory/sun-system-de-reflectors/ac-de-air-cooled-double-ended-reflector-8-in

I don't know what the deal is but I read everyone saying how great they are but I've never seen any grow journal/video that actually shows anything impressive. I like the idea and I'm sure they're great but put up against HPS in pics and vids I don't see it...other than maybe monthly savings in...

I know this light just came out but has anyone found someplace where they're flowering with it (GC-630)? I'm planning a lighting upgrade, still using my Mars II 1600 in my 5x5 tent. WARNING: MEANDERING POST...I've been tossing between COBs, CMH, and 1000w DE in an AC/DE fixture. I kinda...

So you're running 24 COBs to cover 4x4, it just seems like such a bloody expensive proposition. Hard for me to make sense of it, I've been tossing around between considering four 315s in my 5x5 or COBs. Now I'm even thinking of just going with a Gavita 1000de. Plenty of options, all of which...

Hi Realstyles, I made my way over here to rollitup. What size tent is that in the picture? Thanks

Haha, sorry. I was a few sheets to the wind last night when I wrote that. I was curious what the perimeter (outer area of light) looks like, in terms of bud development. You know, given that the buds under the light will always look great. Your assessment of a 2.5' x 2.5' strong footprint...

That's a beauty. Let's see the perimeter.
