Cheers man. That's what I've been thinking. I brought a led years back. Before cob were around. It wasn't that great compared to hid.

Do you know anywhere that does good deals on cmh kits that might ship worldwide.
The old LED just plain sucked. No comparison. The new stuff needs to be worked with for awhile to see what its potential is. It CAN, but for now no one has quite answered the HOW.

There are plenty of suppliers, just gotta go hunting lol

Sorry one other thing. Can you run one of those 315w bulbs off a normal 400w hps/metal halide ballast?
NO, and here's why; the CMH lamp isn't special in and of itself. It actually would run on that ballast. It just wouldn't be very bright.

The whole reason the lamp is so efficient has everything to do with the ballast it runs on. It's a low frequency digital square wave driver; low freq because the ceramic pit can't handle high frequencies and the square wave is why the ballast is relatively expensive, but this is the key to the 30% improvement in performance.

Cheers man. One thing I'm having trouble with is understanding the adaptors. I assume to you can still use your lamp cord, or did they change the plug into the cmh ballast.

Would this work for an adaptor.

Yes, that would work. My 315W CMH lights are actually mogul socket base already, so I didn't need an adapter.

I got kits, consisting of ballast and lamp only. I cut the ballast ends off a lamp cord and a power cable and wired those to the ballast. It is one piece now, but it shouldn't be much of a problem since the ballasts are small and don't run too hot.

I was thinking of trying to source it cheap offshore. But looking at the prices, I'm just going to get raped by our customs and the duty they will charge me will just make it more expensive then buying them here. I can get a setup for about 750nzd, through a grow store, so about 500 usd.

Might be able to get it a bit cheaper through sparky mates and their wholesale rates :)

Might just get one and run it with a 600w hps

And look for kits. My kits were about $200 each. Although I'm not sure I can fully recommend their customer service, I did get them from;

Ask about 315W CMH kits and ask about mogul socket base lamps.

Here's a comparison from my last grow horizontally, same strains, except one plant less this time. Plus this photo was 2 weeks into 12/12, so a few days behind the photos above.

Which will yield more, the battle begins!!
But paulie the most important question is left unanswered..

In new zealand when you flush,does the water go clockwise or counterclockwise?

And dont try and tell me you dont flush either :bigjoint:

P.s plants look good...except the one in the far right rear...don know wtf you got going on with that one.

Haha

My toilet flushes clockwise, but I don't flush my plants. :)

Yeah the ones on the right wall are the super skunks and the ones on the left / back are the wwxbb. Next run ill be doing all the same strain.

Just waiting on some seeds. Been taking a while......well more than usual.

Cheers bro. I was talking to a Sparky mate and he is going to look at ordering them through a wholesaler. Then I can get them at cost :)
Right. Most of these bulbs do not have the mogul base, and I am here to tell you that's it's well worthwhile to get lamps that do; they are a universal position lamp so they'll fit in any reflector.

Will do. Thanks for the tip!

I'm still a little way off up grading. My 1000w needs replacing in June. So may wait till then. Just depends on how much they will cost

Those are exactly the same 860W CDM Allstart lamps I'm using now. Beware, unless your magbetic ballast is receiving 208V, it will run the lamp at 1000W and take another 100W doing it. I'm investigating some other ballast options that would significantly improve the light output of this lamp with the same thousand watts.

Our power down under is normally between 220-240v :)

Would one of these out preform a 1000w hps. I use a solarmax super hps, meant to be 147k lumen (although that doesn't matter so much) but rated for 20000 hours

On a magnetic ballast, absolutely not. On 240V the ballast would pull the same 1kW it does here, plus another 100W for the ballast itself.

I haven't run one on a LFSW ballast, but early reports from a buddy who has been are very encouraging. If it works as I suspect, such a ballast would make the 860W CDM Allstart as efficient as the 315W CMH system, only it operates at 1000W- or, roughly as bright as three of them. For comparison, guys here are reporting that HPS thouies are testing out at about two 315W CMH equivalents.

After a bit of research I think I'm better going with the latest tech being the 315w

Cheers for your help bro. You have a fuck load of knowledge on this shit!!

In the meantime i have a spare 125w cfl bulb. You think there would be any point dangling that in the middle as well, or just dangle it close to the plants and just move it in front of a different plant each day? It's spectrum is aimed at veg
