I'm currently running air cooled 400w in a 3x3 tent, could I run a non air cooled 315 cmh instead just using the same exhaust fan and carbon filter?

Probably too small of a space to avoid heat buildup (based on my nube-ish experience), but mainly depends on how good your ventilation/air-exchange is, and where your tent is located...

i run in a 4ft x 5ft cab .. the rear 1ft or so is for fans and carbon scrubber .. so i figure a bout a 4x4 foot print .. anyway i was running a aircooled 600hps and i switched to the 315cmh non air cooled and my temps went down 6 degrees .. was runnin 79ish now 73 .... so yea you will be fine in a 4x4 cab ...

ColoradoHighGrower is right, it will greatly depend on your tents air intake and exchange. I would add to this that as long as you've got cool/cold air going into the tent a 315 would be absolutely fine.
I myself have an 8x4 with an 8" inline fan pumping in the cold night air from the outdoors. Then theres another 8" inline fan sucking it all out on the other end of the tent. Due to the heat here in Northern California I have to shut down that CMH tent from June until October every year.

Nice! What strain are you running? Fat leaves!
Is that a well-pruned mother in the back left?

Yeah, if I clip 5 clones, it bounces back with new tops in a week or two. NorthernSkunk

So im asking this on behalf of a friend who doesnt do forums, will post in a few of the knowledgeable CMH threads. Hes looking at a deal for Lumii LEC (same as cmh, right?) Ballasters, 315w at 100 euros each, and he can get cheap phillips bulbs as well. Any pros or cons on this specific setup? Cant find very much info on Lumii anywhere but i believe the ballaster being squarewave or not, and the bulb hanging horizontal or vertical are important. Not too interested in sales pitches for other lights/ballasters, were in Spain so many of the US options arent around. Price is important too, as there are about 20 x 600 hps that cant run this summer due to heat, even with cool tubes.
Also looking into leds where i am much more knowledgeable but there i kind of narrowed it down already. Any ideas? Sorry for not having more details, will try to get back with that.

if you are running 20 600 hps in cool tubes and its to hot then it will be to hot for 315 also. 315 doesn't use cool tubes as that would block spectrum. sounds like he needs a couple mini spilts or a big cooling unit.

I should've done this in veg earlier. I was expecting maybe rapid soil drying or an elevated temp. Plants perked up, 77 degrees, 50% RH, healthy moisture in the pots, 6" exhaust on Med/Low. I'm thinking germinating and cloning on a dimmer edge, like offset the light like 3", might be real sweet. 30" from the top of the pot and I love having the tables so I'm not hunched on the floor. Expandible to 100w T5 under the table for cloning and germinating. For 315w - 415w in a 4x4. Liking it

Thx, maybe im not too clear, its not a 20 light room, its spread out over 4 rooms. Manageable but with a lot of ventilation and ac in the bigger room. Im really more after advice on Lumii ballasts, anybody know if they any good? With regards to square wave etc

I tried to get the EBM lighting ballast some of you have but I did not have luck with that company and had to use my PayPal protection.
I did in the mean time buy a few Solis Tek set ups and the plants respond well to the CMH. I did end up going Dual CMH Solis Teks and it really does run really cool.
The Solis Teks are from what I understand, Ultra High Frequency square wave CMH technology. Where the Chinese brand was low frequency square wave technology. The EBM ballast where dimmable and plus lumens the Solis Tek is strictly plus lumens.
No matter what I am really happy and so are the ladies. I also have an HPS running to see what difference I do have come harvest besides the energy savings of the CMH.

EBM is a copycat of SunPlix ballast. Thanks for god they only copied our ballast appearance and some of our ballast technology, but not all. That is the reason you did not have luck with their ballasts. We are the original one.
