I've always read that high frequency ballasts are bad for CMH lights? Not 100% sure on it though. I'm not a DIY'er.

She sure did stretch a ton Turbo! Did you find heat to be an issue with such tall growing plants?

Hi guys and happy 4/20...
They make a "conversion" ceramic MH bulb that uses mogul base and runs on MH ballast. I wouldn't try running a 315w on a 400 ballast though...

I kept it around 83. Lights in a closet with a fan and the door open. It's about 8 degrees hotter than the outside room temp. I will top early next time I grow sativa.
they said because they are unable to design the CMH that can work on HF ballast, also to sell LF ballast is good for their revenue.
the idea is use hps ballast to drive CMH, only change the bulb… save money on a separate ballast

Just be careful. I've heard of bulbs being fried from improper ballasts, and most cmh bulbs aren't cheap to replace!
we will narrow down the condition of usage, that helps user to avoid accident but not everyone read the instruction and do things properly.
Do you still want 315 samples?

Just got some new gavitas for sure let us know how it goes. Are the bulbs jacketed if not you might want to order a shield from growers choice it’s just a glass tube that fits around bulb to prevent fire on bulbs not rated for open fixture use. I run my de 630 bulbs in acde hoods because was worried about it after saw a post where one of the growers choice bulbs caught someone room on fire.
In my opinion some of these lighting company’s are taking a big liability releasing bulbs without much warning they are not open fixture rated. Growers choice sells a fixture to run their 630 and 1000 cmh and it’s high frequency and I don’t think it comes with the safety shield. But it’s not just cmh the mh de bulbs can be dangerous as well. I know growerchoice makes a shield you can use and I believe nanolux double jackets some of their bulbs.

The 315 bulbs are double jacketed at least pretty sure I know the Phillips ones most people use are. As far as the the other bulbs You got im not sure without looking at em but if they look just like an hps on the outside glass they don’t have the double jacket.
I’d still run em if they in work on your gavita I would just order that shield from growerschoice for peace of mind. If they work good let me know I’d love to have 1000 watt cmh but I’ve bought enough experimental fixtures and just wanted something proven this time around. (Didn’t care for de 630 and terrible luck with ballast for em.)

The DE bulb i've sent to you is thick quartz shell design, we've tested and it holds the arc tube explosion.
If you really need the outer glass shell, dont buy from Growerschoice, cuz the bulb diameter is not same as theirs. find me in conversation if you need extra shell.
