A good dimmable ballast is supposed to be the Galaxy. Check Growers House website. Don't quote me, but I think the phantom hood you can draw heat from, and a phantom is similar in price to sun systems.
So what would be comparable or a step up from the sunsysyem unit I'm trying to weigh my options .I used to own one of the SS units with the ballast built in and I would rather not do that again.

Lol trust me I've been on there for a few days no stop looking at things. I'm just confused why you see the DE 315 bulbs from growers choice and not the fixtures ......same thing on Amazon .And I can find the sunsystem setup with the remote ballast configuration anywhere .............
Sorry Bro :eyesmoke:

You're Talking DE Configs :idea:..my bad

Okay, so looking into the differences between the 3000k vs 4000k cmh bulbs, i realized that the lower temp 3000 kelven bulbs result in a higher frequency spectrum/shorter wavelengths.

And the opposite for the 4000k version, which has lower f/longer wavelengths.

This seems counterintuitive, as i thought hotter objects emit higher frequencies of light (e.g., hot suns are blue/blue flames/etc)?? I'm confused...

Yes it is confusing. I can only attest to what I have seen in my grow rooms. If I had to choose 1 spectrum from a bulb it would be 4200 start to finish. Since we now have a choice I am mixing them trying to achieve the best balance. Would be nice is CMH bulb makers would make a 12k bulb so we could use that to finish with.

The 4k is where it's at, everybody says the 3k for more weight, but cmh's are built for quality of spectrum, which the 4200k bulb has.
