I got it guys and gals. I got it all figured out. Thanks and I have a working Sun System 315W. I am excited to use it. is it perfect in a 3x3 tent?
glad to hear you're up & running I'm wanting one of these myself & the 3x3 tent as well using a 400 w. hps & a single waterfarm 29x29 in. scrog this (cmh/ lec) seems like the perfect match my scrog seems a bit much for the 400 hps as my outer growth isn't as dense as the 24x24" center keep us posted my setup is working good but the cmh would be the icing on th cake

Thanks, I will keep you up to date with how well it works for me.

In no particular order;
  1. CDM/CMH/LEC lamps are all the same thing.
  2. They all MUST run at frequencies of about 174Hz or less, or they either don't strike or destroy themselves.
  3. A magnetic ballast will drive one, but not well; see the dark bars in pics taken under lights driven by mags? That's an interference pattern, evidence that the lamp is actually OFF 30% of the time! It's just flickering so fast you don't see it.
  4. A square wave ballast eliminates the dark bars and thus drives this type of lamp much more efficiently. Spectrum output also improves.
Therefore, the only ballast worth running a CMH lamp on is a LFSW type.

To be very clear, even this is a distant second in performance to COB LED. COB LED is fast becoming the new industry standard because of its performance, efficiency, reliability and durability. Costs are rapidly falling, as well.
If you use a Phillips bulb on a digi ballast that can run it but is not square wave, is it any better than using a run of the mill 400w MH bulb/mag ballast?.

What would you personally knock up for a 4x4 cob veg area?.

Your two cents definitely helped. I looked in the breaker box and they had used two breakers into one and had put something over both switches to they both go at the same time but that little piece fell off. Thanks for the help.
That little piece fell off!!?? Not good my man. That piece is to keep the breakers together called a bridge, so if one trips they both trip.
Now I have a little knowledge on electrical circuits not an electrician per say but not a laymen.
In the box there is 2 bars, A and B, both have 120 going to each adding to 240.
240 circuits on a 120/240 system will have one of the breakers on A and one on B both connected with that bridge that fell off. If A gets overloaded everything on that side will trip, if the bar is not there only one breaker on the 240 will trip and you can fry your ballast.

Thank you that is some very good information. I will think about that and I might have a double pole breaker put in instead.

No problem it's baically the same thing as long as they are tied together properly. But if your getting new breakers 2 pole would be the way to go. Just make sure they are rated the same. But these things rock a 3x3 you will be pleased

Will be dropping them in 3 days. 2 of them look like they could go weeks more but will fall with them all.
All flowered under 3×Nanolux 630w fixtures.
Do you not stagger your harvest, at least a little? I can take the first one in the batch whenever it's ready, even before term. Likewise, I can wait as long as day 70 for the last one if it can use it.

The lamps are very fragile.one of the reasons i would stay away from those 630 de ones that are nothing but 2-315 arc tubes with an outer enevelope, id thnk theyd be even more fragile and they run on an ultra high freq sine wave ballast. If the design doesnt add something to ruggedness those 630 de cmh are going to be dropping left and right and their pricey .

All that complexity and fragility and they still don't work as well as COB LED.

They are not DE, it is just a 2×315 fixture.

normally I could jus hang them in my spare room to dry and finish the others, but we are remodeling the room. So the only place left is the flower room.

one day when I don't have to worry about the law taking my Expensive toys.

Two 315 arc tubes fit in a de sleeve. This really isnt even legit. Had they doubled arc tube length and it was more than 2-315s in a de sleeve id be interested its not that so I stick with the allstart with one arc tube thats 3 times the size of the 315.
