@Frenjamin Banklin If you watch and listen to the videos on my main thread from Subcool, Pedro and SOOTDAWG they all document their grows and say a lot about the light. They all say that they love it and it's kicking ass, I highly recommend you give them a listen.
They heap praise every time and talk about their hanging heights several times, please watch and listen to the videos on my main thread and let me know if you still have questions.
Subcool has 4 Cannons over about a 4'x7' area and his canopy is perfectly even, please check out the recent videos in my main thread.
Spread is not really an issue or a selling point, I'm not sure how it became such a big question. People can get even growth over a 4'x4' with a single 1000 Watt HPS, why couldn't they do it with three 240 Watt COBs? It'll be 3 times easier. Spreading the light more than this could not possibly be more important than cost or efficiency.
I recommend an 18" hanging height for a perfectly even canopy over a 2.5' x 2.5'. You definitely do not need to worry about uniform spread of light over a 2.5' x 2.5' area at 18". Here's a picture of the Cannon's spread with and without a reflector, without a reflector the light from these COBs comes out at almost 180 degrees:
NO WORRIES! That shit is wider than all outside:smoking:
This light is designed to cover a 2.5' x 2.5' area, and its easy enough to use multiples so I definitely think its viable for commercial growers and home growers. Just clip on a $6 ratchet hanger and you're off to the races.
I don't think it means anything to say a light is "for photoperiods". If autos need less light intensity you can raise your light and cover more area. It's the same thing growers have done since the dawn of indoor, why is it a question now? Also, you can dim the Cannon 1 Watt at a time down to 120 Watts if your plants need less light. So it's for autoperiods and photoperiods, just like every other light.
Pedro is covering a 3' x 3' with a single Cannon, and he has it about 20" above the lowest part of his canopy in the center. Here's a video he just posted about his hanging height:
His entire grow and all his impressions of the Cannon are documented in the recent videos on my main thread. Spoiler alert, he's filling out an entire 3'x3' with a single COB and he says every time that he fucking loves it:smoking:
The point of the Cannon is to be a powerful, easy to use, high efficiency, low heat, fully assembled, plug & play fixture at DIY prices.
The really important metrics are
dollars per watt and
efficiency in umol/J. That's why they're on the LED Buyer's Worksheet at the start of this thread, they tell you what you're really getting.
Again,
DOLLARS PER WATT and
EFFICIENCY!!! Super, super important. How much light are you getting and how much is it costing you? Would it cost you much less somewhere else? Its all on the worksheet, 5 questions at the start of this thread.
I made it really easy for everyone to do the math for themselves, because I think that was the best way. Now nobody needs me to make direct comparisons. Seriously though, my main thread is covered in opinions and results from well known growers. Not sure how that's still in question.
Thank you for your input and your civility! I highly appreciate a good discussion, and I'm hoping people will ask questions and benefit from it. Please check out the worksheet at the top of this thread, everything you need to know about the value of an LED Fixture is on there. Happy growing brotha:smoking:
Please help me keep the peace my friend:smoking:
