He currently offers a DIY kit as well- 315w mogul lamp, socket & Philips ballast. Dunno that he offers the pgz stuff at all.
I think ( I may be wrong) that he ships voltage converters as well.
He's not the place to go if you want plug&play.

Thanks for the info. I also thinking about reflectors, like if he sells a complete luminaire kit.
Dunno. With an open fixture rated mogul lamp, it's your choice of reflector & a minimum amount of wiring at the ballast. Put two in one of those whopping big dual lamp reflectors if you want & have the room for it. Proper geometry of the light emitter in the reflector is built right in.
One of these per ballast-

plus cords, converter if you need it, plug ends & wire nuts. Plus a few tools, a little common sense & ingenuity, typical DIY. I think his efforts are geared to DIY'ers.

Yea, that's what I thought may be the case, all other components still need to be purchased (e.g. reflector, wiring, etc.). But even after buying all other needed components it's still a good deal from that company.
However, piece-mealing a luminaire is very likely to provide reduced radiation uniformity and reflection efficiency vs. than buying a luminaire where the reflector was designed for specific lamp.
It's great all these options on the market, from complete luminaires to complete kits to piece-meal kits to single components. For people who are all thumbs (me) to DIY'ers.

I think that horizontal mogul grow reflectors are designed around the geometry of standard BT37 & ED37 MH lamps & ET25 HPS lamps. The center of the emitter is basically the same distance from the base for all of them & for the mogul base 315 as well.
It's plug & play with a Wellthink ballast. I have no idea if they're good or not.

The Welthink ballast is fine, but not as efficient as the e-Vision or CeramaTek (and useful lamp lifespan is reduced, I think). The only reason the Welthink is used by some luminaire manufacturers is it can run on 120V natively.
Greenbeams offers the Welthink ballast as well as the other two, and the Greenleaf Nutrients company sells a complete luminaire (315W CMH) with that ballast:
http://greenleafnutrients.com/index.php?main_page=product_info&cPath=11&products_id=42
About reflectors, ideally they should be designed for specific lamps, as the geometry and length are different in most cases. This has to do with restrike as well as angle of incidence (the placement of the arc tube is only part of the equation). If a grower cares about optimal design then one-size-fits all is not ideal (but works fine regardless).
I've tested my newly arrived ceramatec ballasts but the dimming feature doesn't seem to work on these two. There's 13.5vdc across the purple & grey leads, but shorting them together does nothing. Supplying 9vdc to the two leads also does nothing regardless of polarity. It's also kinda weird that they both have the same S/N.
I wasn't planning on using dimming but I'd hoped to gather some information for other people. No such luck.
They're keepers, anyway. They suit my purposes just fine.
The amount of light coming out of that little ceramic egg is quite remarkable. It's a *lot* brighter than the older tech 330w CMH we use to supplement houseplants in the winter. The spectrum from the 930 lamps seems warmer to my eye, as well.
Barring an unexpected attack of ambition on my part they won't go into use until after the current round finishes, hopefully the end of July.

Hello everyone
I just registered to ask one question regardless philips 315w CDM lights.
I have read a lot about them and Im desperate to get one but my issue is the footprint. Some people says that one bulb is perfect for 1m x 1m area but others uses 2 of them or even 3 in a 1.2 or 1.5 sq m room.
What I want is to cut my bills a bit and get better light at the same time but do not want to spend £500 if will not have enough light for my grow area.
Have a 1.2m x 1.2m tent and wondering if one 315w philips fixture would be enough ?
There are only 3 things on the market Im interested with:
1) D-papillon 315w (but do not know if it will be enough for my tent, other option is d-papillon 630w with two bulbs)
2) DimLux Expert Series 315w (same issue like the above, will it be enough? if not then DimLux 630w)
3) Kind Led Grow Lights K5 Series 750w
Thats my options Im wondering about. Im a hobby grower so I want to spend as little as possible but do not want to waste money from the other side. One thing will not change - my grow area which is 1.2 x 1.2m. Im not a fan of led lights so the 3rd option is the last to consider for me.
Is d-papillon and DimLux reflectors at the same level ? Or one of them is better ... I would be really grateful if any of you could advise me with that.
At the moment I want to go with one d-papilon 315w with daylight bulb for veg and first week of flowering and then with greenpower bulb.
Thanks

I've done grows in that size tent with both one and two lamps. A single lamp works ok, but at @19.5 watts/square foot, it is really quite a bit less than optimal. Two lamps will give you 39+ watts per square foot, and works very, very well.
I can't help you with either D-papillon or Dimlux performance since I haven't used either. These lamps will outperform any commercial LED of vaguely comparable wattage that I've seen.

Like rives wrote, you're pushing it with just a single lamp, better would be two. But in terms of luminaires, it would be better to have two separate 315W fixtures than one 630W fixture, in terms of uniformity. So it would be better to have for example, two dPapillion rather than one Double dPapillion.
Is the canopy itself 1.2x1.2 meter, or is that the floor area of the tent? (It's generally best to leave a little space between walls and canopy for optimal air movement for homogeneous temperature vertically, as well as increased radiation reflection off of the walls for greater intracanopy and bottom canopy irradiance.)
If the canopy is less than 1x1 meter, and you want to start slow, maybe just buy one 315W luminaire and see what you think after a grow, then, if you want to buy another (which is likely optimal), you'll have two 315W luminaires (which is better in terms of uniformity vs. one 630W luminaire, anyway), and you won't have to pay as much at one time.
I haven't seen data for the Dimlux CMH reflector you're asking about, however, looking at that model you listed I see it's a specular surface, while dPapillion is a diffuse surface. So just by that fact, I would suggest dPapillion, because diffuse surface provides better uniformity of irradiance.
Knowing uniformity the data for the ePapillion reflector I would suggest them vs. the style of the Dimlux (which is very similar to Gavita style reflector) for the sake of better uniformity of irradiance.
Out of curiosity, why do you want to use the 942 for veg and pre-flowering but the Greenpower for flowering?
Either lamp will work great, and there's not a large difference between them. However, that said, the 942 does have a better spectra for plant growth (and much more UV-A with a good amount more UV-B), but the Greenpower has greater efficiency in turning watts into PAR range photons (due to the greater % red from the Greenpower, which also has less % blue).
imo the 315 covers a 3" x 3" footprint nicely, since you have just over a meter i'd say go with the 630 and make sure you can control the environment in your tent, shouldn't be too hard.
I've only used one 315 at a time, never stacked them next to each other or mixed in rooms with other lites (yet
). so i can't really speak onthem overlapping in that small(ish) space, can't imagine it being a bad thing.
I think that people using 3 x 315w bulbs in a 1.2-1.5 sq m room is a tad overkill, BUT, some fixtures arrange the bulbs vertically which (imo) reduces the footprint, so may be able to cram more lites in when arranged vertically in fixture....

It is all about the money ... single or double lamp is in similar price
I can have dimlux 630w for about £500 and the standard price of it in UK is over £800 ... minus of a single d-papillon is no dimming option (in a case I would get two reflectors that would be constant 630w and £950 out from my pocket)
Homebox Evolution PAR+ 1.2 x 1.2 x 2m, inline fan 500m3/h, currently running hps 600w
only 1.2 x 1.2m area
You just answered yourself
I will get both bulbs anyway (if decide for a d-papillon 315w, they are included) so want to take the best of itand thats the prices I can get:
d-papillon 315w (with two bulbs, 930 and 942): £475
d-papillon 630w (two 930s or two 942s): £699
dimlux 315w (two greenpower bulbs): £365
dimlux 630w (two greenpower bulbs): £520
couldn't find an edit option, if there is any then sorry for quotting
Shame I can't edit yet. I have misunderstood you. For me the canopy and the floor area was basically the same thing
I am foreigner who lives in UK and my English is not fluent. The canopy is of course less then 1.2 x 1.2m, currently I have there 6 plants in 10l pots and one pot is 25cm wide.The biggest plus of dimlux imo is that the air can be extracted from the reflector which can be very helpful during the summer period

It seems from you response maybe you want to use Greenpower in flowering due to the greater red in the Greenpower? If so, I think you're basing your plan on flawed logic, that is, the often made claim that HPS (red) is for flowering and MH (blue) is for veg. But that claim isn't correct, it's based off of very strong misunderstanding and assumptions of 'experts' from over 20+ years ago.You just answered yourself
Check out this thread to see how Cannabis absorbs spectrum from veg to flowering (there is very little change):
https://www.icmag.com/ic/showthread.php?t=293045
And this thread about how radiation is used for various plant responses:
https://www.icmag.com/ic/showthread.php?p=6718314
In other words, you can use the Greenpower for all growth stages (veg to flowering), or the 942 for all growth stages, and have great results. There's basically zero valid reason to use 942 for veg/pre-flowering and Greenpower for flowering, however.
1.2M square is 15.5 sq. ft. That's40w/ sq. ft.
CDM might be 50% more effective at converting electricity into visible light so that's the equivalent of 60w/ sq. ft of HID lighting.
1000w HID is commonly used on 4'x4' areas at 62.5w/ sq. ft. It's generally regarded as the point of diminishing returns & has worked well for me.
That's guided my thinking into the move to CDM. It'll be awhile, but I'm eager to find out if I'm right about that. I figure 40w/ sq. ft. of CDM should work great & reduce heat issues in no small way. That means I can slow down the fans & cut noise as well as saving on carbon filters. Other than the upfront costs, it looks like a winner to me.
If I can get past a lot of other stuff I need to do, I may go nuts & switch over before this round finishes.
