Thanks for the reply guys, looks like I’m going the DE direction. It’ll be interesting to see how they do vs the 650w strip Samsung lm301s
Unless something has changed with them, I'm pretty sure you'll be selling it and getting another LED lol. You just cant compare to these panels now. Between the savings in cooling and being able to get the panels right ontop of the canopy. Best of luck and let us know how it turns out duder.

You pulled 10 elbows with 4-630s? That impressive if its so...I've gotten 10 elbows with my 4- 1000w and a 630s, granted I am growing all cookies, wedding cake and gelatos and hit those numbers with my very best yielding phenos.
Gelato33 x’s with og’s.

I would only recommend dual bulbs as Phillips bulb are proven to produce. That said, I am transitioning to led cause same wattage will produce same if not more gpw

Isn't the consensus somewhat that dual arc tube cmh lamps are inferior to multiple Philips 315 lamps?
I had read somewhere that arc tube stability issues was one main issue.

Well i have just completed my 1st grow with Two 315cmh lights, 4 plants in a 1.2metre x 1.2metre grow tent. I grew the plants in coco using nutrifield nutrients. No lst no scrog just some light defoliation around main budsites, an ended up with 20oz of nice buds. It was surprising that the lower flowers did end up quite solid. In my opinion they are a decent light source for growing cannabis

Awesome job bud, I love the cmh too.

Anyone bought and used one of the newer Chinese vertical 315 fixtures that are about half the cost of Sun Systems?

Examples:

I get that they are all super cheap and might have ballasts that crap out after whatever time, but they are only marginally more expensive than the Sun System hoods without ballast and one could just wire up a replacement external ballast and be back in business pretty quick. Still less than half the cost of original Sun System 315, and I think you even get a lamp (probably not as good as Phillips..)

Nothing else I've seen on the market gives that same unique light footprint through the reflector (with 5 hot points).

spending $200ish a piece sounds a whole lot better than $450-500...

If that isn't a rip off of a Sun System fix I don't know what is. China knock offs aren't even trying to hide the fact a little that they steal patent and design copyrights from their owners.

Likely, but I hope that the internal components are higher quality with the sun systems, the cost has to reflect a better quality, least I hope..

That thing, without ballast, is over $200, and no lamp. This is why I'm thinking I don't care if the ballast is sub-standard, it can just be replaced with one of those nifty Etelligent dimmable units later. ;-)

Cost difference may only relate to branding, everything, all parts are sometimes identical, lots of imported merchandise is like that, helps if rebranding outfit is in your country.

Try this again. Yeah Sun System stuff isn't cheap nor is Gavita, nanolux ,hortilux and few other brands I trust. I figure the money I spend on quality grow equipment is worth the peace of mind knowing it's less likely to burn my home down which my love ones and I live in. Getting setup to grow properly costs real money, how much is up to the grower. Personally I figure the money I spend now is money I would have spent on buying weed and other weed related products in the future so why not go with the "one and done" approach. I was okay with buying a couple of knock off lower wattage China made LED's early on but I'm not going to take that risk with higher wattage HPS/MH/CMH lights. Not long ago I installed a new LED outdoor security light for my inlaws and first had to remove their old MH light. I took the MH apart afterwards which was a cheap china made light, the ballast on it was cooked, it had melted down to a gooey mess and smelled of a horrible electrical fire. Luckily the fixture was away from the house and incased in a metal fixture that contained the fire. Imagine that happening inside of a tent in your spare room or basement? No thanks..
P.S. The CMH fixture I bought has a dimmer which is fancy but worthless unless you are running it with a controller that it was designed for.
