http://www.gel-usa.com/downloads/products/ceramatek/CT375W-spec.pdf look at the spec sheets

Ceramatek Kit Part Number:

GEL375WKI 840 U Position 200-277
BUD
HOR

IDK why they state 120v-277v on the basic info..........even genuity got the same 200-277v #'s when he called
if they only realize how many people would jump on that if they had 120v... Very few people have 220/240v lines aside from washer dryer outlets.. I need a house on 1/2 an acre at least... I guess all starts are still the way to go. growers house option is over priced imo.

I know and your right..............don't wanna run a step-up, and most electricians charge $150 to run a dedicated line(depending on length) which is worth it for safety alone. BUT I rent:(

I don't understand how they can't see a demand for a true 120v option, shit would sell like hot cakes!!

do you know who makes the 375w cmh bulb in the kit hyroot??? because I can't find it anywhere

Thanks Hyroot. I'm a novice to CMH and the Elite Agros are my only experience. Is the spectrum on the 860w similar to the Elite Agro 315w. After all that's why I was wanting to use them....
http://advancedtechlighting.com/cdmea860.htm

they also have the 330w allstart too. Runs of a 400 mag mh ballast.

cococola posted a link for electronic ballasts for the elite agro that are cheaper a page or 2 back in this thread...

Philips master colour . Bulb runs on 120-277. CeramaTek ballast on the other hand 200 -277. advanced is supposed to be dropping a 120v. I'd imagine it would be a CeramaTek.

it has lower cri than elite agro and allstart... I'd rather go allstart

I was having that problem, too. Beautiful spectrum chart, hope it isn't a unicorn lol

My business partner and I are starting up an MIP for primarily providing concentrates, but also tinctures and capsules, just no cookies or lollipops. I would love to build out the grow with the exact light I'm using, but the cost would be insane.

500 plants x 9 sqft/plant (we grow trees)/9 sqft of decent coverage = 500 lights x $500/fixture = 250K..... that's more than my entire budget at present..... I'm thinking HPS unless you all think I could do it with the CMHs for a reasonable cost. Any thoughts?
I grow trees, too- and the way I'll be using these bulbs, they'll cover 25 ft² of trellis space apiece. With trees. I'm getting two per stem now, with two year old HPS bulbs. These will certainly improve things, both in terms of yield and quality.

They'll pay for themselves many times over the very first run, it seems cheap when I think about it that way.

Well depending on how many you want, a step up transformer is only $30 on amazon.

I'd be concerned about loosing efficiency/power using a transformer, and another failure point. I think I'd only do it if I had or put in a 240v circuit, 20A could run 2 of them.

I have good news. I just off the phone with the guy's GEL, and apparently due to a friday fog I misheard him. The ceramatek ballasts are actually 120-277v! :clap:

Even better news. The 315watt kits are $419 and the 375 watt kits are only $479!!! :hump:

Nice, I had noticed when I think it was hyroot mentioned that they said 120v on the main page. So it's down to this or DIY LED's.

Is it recommended to run these (vertical) bare or hood them? Have never run this type of light so no idea what would be the most efficient. For the efficiency, life, draw and cost, these seem to me like about the best bang for the buck right now. I'd be using them strictly for flowering...

People have been running the T12 bulbs in both configurations. It's the T9 that is restricted to closed fixtures only.

Awesome news, so they definitely work on 120v...........wonder why the spec sheets say 200-277v though??? whatever, I guess it's me misreading it then......

So who's gonna be the guinea pig and buy one to test the 120v input???? :)

I'm in the same boat. cmh or diy cobs...


Vert will always be more efficient and more coverage.

Yeah, thinking this and use some of those extra LED panels I have using reds only to supplement, that should grow some bud. I may just go for it and be the guinea pig. Just have to get my head around what else I'll need, thinking some form of hood with the right socket but don't those run them horizontal? Sounded like I should be getting the vertical from one of the posts earlier. I'm thinking I should run the ballast outside the room as well so will have to rig that up. I have plenty of 120v sockets in there to run lights only on a dedicated light circuit so I'm good if it runs on 120.

I'm of the opinion that the closer the ballast is to the lamp the better, yes? Isn't this true even of digital ballasts?

The way I read the spec sheets, the vertical bulb spectrum actually looked a bit better, and it was protected.

Most of these cmh bulbs are designed to run vert, some are universal position but your numbers drop running them horizontally......obviously only protected bulbs should be bought for our purposes ..

A cheap umbrella reflector will do if you go bare bulb.....but you need space from the heat though.

Good luck and keep us posted

^^^^^^ yep closer the ballast the better the performance sort of speak. Vert imo looks better too. It has plenty of deep red so no supplemental lighting is needed. Plus uv-a and uv-b and IR which led lacks... Led performs very well though. I like my ig's more than my a51. So I'm sort of leaning towards CMH... Or maybe both. I have an extra 5x8 area to use..

run bare bulb true vert and set a fan on the ground pointed towards the bulb.

I'm vertical bare bulb with HPS thouies right now. No umbrella necessary or desired. These aren't going to be a problem!

Yes that solves the heat issues in small spaces, but you lose bulb efficiencies when cooling it directly......might be worth the trade-off for some.

I never did, but had massive air circulation and exhaust.

I used the umbrella to "catch and bounce"light back towards the plants. The bulb was around 2.5 feet further down.

The 375w cmh kit will not replace a thousand watt hps for growing, lighting up a parking lot maybe:p
