I'm confused. That's what 315s are made for (3x3) at 35w/sq ft. You're comparing that to HPS at 49w/sq ft?
I agree with you that having two (for more cross/lighting where their footprints meet) could improve things greatly. I think that helps *any* lighting, and can be accomplished with sidelighting around the perimeter of the tent (cheaply, with household LED lightbulbs with their globe removed. You need to power those through a GFCI outlet though because without the globe there are electrical surfaces exposed. It's not as simple as I might make it sound.).
Your 600w HPS might not benefit as much from that cross lighting because the intensity reflects better back from the walls of the tent? Or, perhaps it has a more even footprint than the CMH.
There are LED users (Amazon variety) who say the same thing. They run 80w/sq ft. (I'm waiting for someone to run 1gigawatt through a steel bar to illuminate a space.).
Doesn't light quality play a more important role? Fewer watts for the same ppfd?
I've never used HPS. I can't compare. But, googling produces many results saying CMH is more PAR efficient. Aside from topics of reflector performance, it should do better watt for watt. You said HPS runs the same temperature. But, that's with an aircooled hood, I take it? (You mentioned class front). CMH has glass-front, air-cooled hoods too. The heat of CMH doesn't seem that significant to me to incur the light-absorption of the glass.
Yoooo. The original post was kinda fun.
Firstly as you said that HPS will eventually go extinct.... NO they won't.
Because no matter how much you pay for your LED,COD or anything else will never have the penetration power of HPS.
Don't get me wrong i am rocking all LED in my tents but it's the decision of the circumstances and not my wish.
You where going on about honesty in sales... How high are you? There has never been a salesman that will tell you the truth. You just need to live and lurn.
Longevity.... Well the LEDs will last long even if you buy cheap ones... Well the cheap ones will probably last longer because they are not pushed to their limits.... But anyway they will last longer then HPS but the HPS are cheaper to replace.... So anyway you look at it your fine.
And the last thing you wrote about was why you are smoking weed. Who cares? You like it... It's your thing... Do it.
Even if it's just the way your balls feel after you smoke lt's ok. Smoke on!!
I wish you all the best.

LmaoThat dude obviously is still using mag ballasts and metal halide street lamps. :)
I resent the sales comment. I managed at car dealers and trained many salespeople. I believe in a consultative style of sales. And to never lie. If you dont know an answer to a customers question you always answer “i dont know” “but i will find out for you right away”.
Finally the LED guys on the sidelines. I know I'm a terrible person for this but honestly how many lighting debates are not involving LED.
Curious what type of led's you are using that dont penetrate well?Yoooo. The original post was kinda fun.

Noooo! Don't dooooo it. It's a trap they will will unite and turn on you.Curious what type of led's you are using that dont penetrate well?
@Burned Haze HID fight on isle 4.
Sorry guys as an LED user I just can't resist. But very good debate in learning here.
The exception doesn't prove the norm. Used-car sales (and timeshare presentations) are a meme for a reason.

I know just trying to over dramatize it a bit. It's not often we get some good debates on varieties of HID.Im not fighting. Led is still twice a reasonable price for a quality pre built and warrantied lamp in my opinion.

CMH seems to work better on the canopy of a scrog like you said it penetrates a bit less..but again HALF THE WATTAGE of a 600 watt hps.
This guys grow diary and bible sounds like he had a different experience than you. And he doesn't get paid to sell lights either. They just sell grow bibles
Afor your 600 hps watt beating your 315 watt cmh well I would guess so dude..your 600 watt puts out double the power of the 315.......I would hope it outperformed. Point is. Only 30% more for yeilds for 300watts more? Why not run two 315 watts have the same btu. Better coverage than your 600 watt hps and get 70% more yeild ?How to Grow Up to a Pound of Cannabis with a 315 LEC Grow Light (CMH Grow Light) | Grow Weed Easy
Ready to grow up to a pound of cannabis at home? All you need to do is follow the 8 simple steps of this growing tutorial using a 315 LEC grow light.www.growweedeasy.com
And there is no way your 315 watt puts out the 1 farenheight less than your 600 watt hps if you look at it scientifically/mathematically.
Your experience and variables could make an huge difference from your setup to someone else's
1 watt of power is 3.4 btu.
315 watt = 1071 btu
600 watt = 2040 btu
When u buy an AC for your tent you purchase on how many btu it needs to cool.
1000 watt btu is a big difference
Basically your saying you dont need to have extra fans or exhaust and ducting with a cmh like you do hps. Which sounds like a bonus as well. You can just run a 315 watt open (like their designed)
I have an 8x8 tent and had to put a 1x8 foot isle down the middle. And a 1x4 foor isle at the front to get into the tent. So a 315 watt with a 3 square foot flower foot print works for my situation
I didn't want to to turn this into a vs thread me and aqua man have been through that discussion many times . My statement was simply every single lighting technology has its place and each one has it's own pros and cons
That is sick. Thank god that where i am growing it's still iligal:)
what are you going to do? Grow underground for your hps?
because of the statement 315 can equal a 600hp
