But you don't have any quantum boards, so here you are talking right straight out your ass again.

And you can't grow healthy plants so your tests are completely meaningless.
Should we show results again? My garden yields more grams per square foot than yours and with much higher quality. And in compliance with Michigan rules which you could never keep up perpetually. You would have to keep to a schedule instead of play with hobby lights and post bad info online.
I referred to studies and proof. Not my opinion like you. You still have offered no results or any real information to justify your argument.
Go back to your own thread and bitch. You are already fully discredited here.

Sorry about that. I tried to post pertinent info to consider but his responses piss me off. But what I wrote about cmh is documented by professionals.
Please carry on

This one looks interesting: https://www.growersc.com/315w-3k-r
Just looking at the graphs seems to suggest more energy from
other bulbs (i.e. 4K), but I am not certain.

I don't use new untested stuff but that bulb looks nice. Just can't know if it has Phillips quality. Or if the claims are valid.
Growers house previously tested the Phillips 315 3100k cmh to have the highest par over all the bulbs they sell. Even the 4K. This one you show is new though.

Hey lec growers, I'm considering going this route for my new veg light.
I have a couple questions if you all care to help me out.
So I want to replace a 400w mh that's in a 2x4 tent. I see these LEDs at 315w, you guys think I'll get as good of growth comparatively?
I also see they are cooler, but I'd assume I still need to cool them in a tent, but the reflectors I see aren't air cooled. Will a 4inch in line exhaust fan be enough to keep the tent cool or do you guys have a different method for cooling your tents with these?
Lastly, if I'm only using it for veg, do you think a 315 lec would be better than a 4ft, 8 bulb t5? Would it be better than 2 Mars 300s? What are the pros and cons for anybody with experience with any of these?
Thanks for any help

Cramming an LEC light in a 2x4 tent is a tight squeeze, it can be done, but it doesn't allow for much airflow around the light for cooling. If you could bump it up to 6 inch inline fan in a 3x3 tent you would be golden, but I get that you're trying to work with what you already have. Using a clip on fan above the light, so its blowing on the back of it, will help keep the hood/light cool.
A 315 LEC will destroy any T5 setup or Mars LED in veg. LEC is easily the best overall light I've used, for veg, and bloom. In veg, they produce thicker stalks, and sturdier branches, which increases yield. I've vegged the same strain under a high quality T5 light, and an LEC, and the results weren't even close.
LEC > T5

My bare bulb vertical socket mounted 315W CMH will kick ass in that tent.
I can't use them anymore so I have to sell them.

Cant use them based on that new bylaw?
Or because
your switching to qb boards for better efficiency?
And the quality is the same?
Your thinking you'll be able to get 3-4 pound trees with souly qb boards?

Thanks for the reply. You made me alot more curious about these LECs.
How would a single 315w LEC compare to a 600w hps in flower?

I'm not sure because I'll use them in conjunction with other LED lighting.

Really close, but not quite the same quantity. Great quality though. Much easier to manage.

I have been using both and the 315 Phillips 3100k bulb in the sunlight supply remote reflector yields almost the same size and density but in a 2.5' x 2.5' area. Out to 3 feet the plants demonstrate some leaning and leaf adjustment to get more light.
And the lowers in my dense compact plants are slightly less dense than my Hortilux 600w and the Hps handles 3.5' x 3.5' easily.
However. The cmh seems to make plants a little greener and happier and maybe leafier but with more natural outside looking, smelling and smoking buds.
The combo is working very well. I am going to go 50% each in my room next. I have 2 to one now and am going to try a 600w Hortilux blue mh in my other hood to try to match the full spectrum to see what 2 to one the other way might be like.

Any thoughts on this one... would it run the philips 315 as a replacement? I Have leaned heavily on the "Less heat, more energy efficiency side of the MH/HPS vs. LED" side of the issue for a long time.... as well as the lifespan of the LED... But these CMH's seem to offer the best of both worlds.
Again, any thoughts / Experience regarding:

This unit was rated best value unit in the above linked info, but I like the in-line cooling the other offers (as well as the price)...Am I wrong, or should I grab this one?

That is the older tech bulb and it is actually only rated for closed reflectors but they show it open.
The new 315's are run on the newer square wave ballasts and offer more par consistently. And the new bulbs are ok for open use and universal mounting but are designed to be run vertical for best effect by Phillips.
I am sorry but have not actually used the 400 w cmh. But I wonder if a metal halide with a digital ballast may be better. I understand mag ballasts can be way less efficient and put out way less light.

All watts are created equally, a 1000w LED will produce the same heat as a 1000w hps, first law of thermodynamics.

not true. there are 2 variants of the older Philips 400. both can be run open but one had to be run horizontal, the other vertical. they were a helluva bulb. and what got me started liking the CMH concept.

I thought the old good bulbs were Phillips and discontinued and the one shown was the GE which is an inferior copy and only open rated and only available as I said.
