I have a bunch of optically isolated dual circuit arduinio relays that i got for 1$ each off ebay that have been driving 2 of our ballast for a long while now.

Rives is probably right that a slower acting fuse might solve your issues.
OTOH, returns are a snap w/ Amazon & the price delta for a higher capacity unit isn't large. I wouldn't fight it, but that's just me.
Hello! Great thread, rives! I have been reading up on CMH/CDMs for two days now and my head is swimming! :-/ (very appreciative of everyone's input though!)
A few questions:
-So the ATL guy is responding and shipping again?
-Does the ATL combo kit come with everything you need for the 315W system (including lamp) to run on 240v? Or do you need a transformer or relays as people are discussing the use of?
-Does anyone have experience running pulse-start MHs? Someone linked this site:
http://www.venturelighting.com/LampsHTMLDocuments/Uni-Form_400W_lamps.html
Anyone have any experience with any of these lamps? Does anyone have spectral analysis or experience with any Pulse Start MHs? (other than the 860)?
-Anyone know why Cycloptics have an "All-Bright" section and then the "Greenbeams" section - which appear to be the same lights, but never is one mentioned on the other...? Is Greenbeams just their "individual light systems pre-packaged and price-jacked for growers" offering, as opposed to their industrial re-lamping, regular-price "All-brights" - which are the same thing just not set up as individual plug-and play systems? Seems pretty weird...
-Does anyone have experience with a relatively cheap LED panel ($150-$350) and ideally 150-250 ACTUAL watts consumption that can veg a 2.5'X3' space well (VEG only) or two or more small panels in the same price range that work WELL for aggressive growth?
-Has anyone created a DIY light with regular screw-in (E27) bulb sockets and cheap, mass-produced CREE white LEDs?
I would like to compare results of the 315w CDM w/ cheap LED (a Red/Blue panel and/or a DIY screw-in LED fixture) for study of what will produce the most aggressive growth for the least wattage in a small (2.5' X3') garden. Since this is around the garden size many people are discussing here, I hope this will be valuable to everyone. Thanks!
Also: Here's a link to a good deal on the Sun System 315 LEC ($413) for a pretty decent rate if people want to go the all-in-one plug-and-play route.

you should number thoes points
2) atl is complete. reflector i am not sure on. the relays are to control light timing. not all timers run 220
3) yes. yes. not I
4) ask BTT
5) talk to rives
6) see #5

Atl is back and shipping, though he never called me to help me with my transformer troubles haha
and as far as the price of the greenbeams go you can probably get them to honor this - 420$ for either the 120v welthink/ or the 200-277v advanced ballast advertised on the adam dunn show

Check out the Volks led link in my sig for a cheap DIY answer that works well for vegging. It's what I still use for vegging a 30"x30" area, and could easily be upgraded with COBs.
I haven't used the Cree lamps for that purpose yet, but will be trying them in the near future.

I got the new CDM lighting system all wired up and running a heat test right now !
Doesn't do it justice
Just a short vid of the machine !

By the way, for you guys here with experience growing with these lights, my plants are 17 days old, 3 nodes pushin 4.
When is it safe to put these under the 315?
When is it safe to put these under the 315?
I've cloned and have vegged under plasma and the 315's with no problems. Lamp distance seem to be the key to not having to much intensity at those early stages and stressing them out. In cloning I've kept them at 36"-24" away and try to keep them around 24"-18" during vegging or flowering.
Have had them as close as 6" away but seemed to have had some light stress especially with the mogul versions, I assumed because of the excess UV output. In glass lensed reflectors the light stress was definitely lessened at that distance.
Afaict from a distance, it's a matter of opinion. It's hard to say if Philips developed the agro to grow better plants or to have the lamp equivalent of better bag appeal.
Marketing rules the world.
I doubt that it makes a helluva lot of difference either way.
I think that Rives has used both.
Jhhnn makes a good point. All personal preference. To many variables like strain genetics, environment, growing style, grower experience, etc.
From my experience the 4200k will do fine but seemed to not put on the same weight as the 3100k. Adversely though got more resin production from the 4200k. This is with my current style and strains though. And that's changing for me with dual kelvin runs that I'm doing right now.
Plus I use two different type a cmh lamps which plays a factor
At my work right now everyone is raving about gavita DE's but I'm a believer in cmh personally and got a few loving the dual 315 fixtures after sharing my input.
Some want as much weight as they can get others strictly want quality and of course everyone wants both.

BTT says that the agro has not beaten the 942 in his testing so far, IIRC
i've got seedlings sprouting under mine, not dimmed and they are loving it
also ATL is Just bulb and ballast
no transformer no socket - just bulb and ballast
still a great deal

Thanks man !
I appreciate the reply.
Got them all settled in to their new home yesterday!
It's ON ! :big grin:
I got tracking for my order, but I'm sure if ya just be patient and he'll take care of ya
cheers
