I've visit the driver recommendation page daily

Sorry, that wasn't very clear. I was just saying that I have two 4xQB120 fixtures, each with an HLG-240H-C2100A. You can definitely max the boards out with a 240 driver. Remember, Meanwells give you more juice than they're rated for. At full power on my first fixture, each board is at 63.5 watts.I've visit the driver recommendation page daily
I don't get the 2x240. These driver run the boards @ 50w each, right? All 4 boards would fit on one driver. Why use 2 drivers? Is this a redundancy thing?
My other fixtures are all wired in series. I wanted to run the boards @ 60w and max out the driver so I decided to try out CV. hlg-240h-c2100b240-24B should be here by the weekend.
The real problem is getting the boards..
I hear you, wouldn't mind another 8 myself
Wow! I don't get it.. Going By HLG's table on the page, the driver must be providing 2500-2600mA to get 63.5w from each board. You say it's a 2100mA CC driver. That means you're getting 20% more out of the driver in terms of current?
Based on my Kill-A-Watt, the four boards max at 254w total.
I have the same driver. B version and getting the same max watts. Still, how come a constant current provides more current than it's rated for? By at least 20%! That makes the output unpredictable (not that I'm complaining about the extra watts).
I'm given to understand that, in general, Meanwell's drivers offer more current than they're rated for, and sometimes by a significant amount. Remember, HLG's 260w kit uses a 240 driver.
Without telling us how many watts you're planning to run through each board, the answer is 'about a pound'.
Depends on driver. Im sure if you dug through this thread you could find some footprints and make an educated guess.
So total power draw at the wall is 640w to get the output of a 1,000w HPS?
Watts in is heat out, so roughly similar to a 600W lamp. Better light distribution and improved spectrum also help yields and quality. Notice the potential for savings both in terms of direct usage and energy required for environmental control.So total power draw at the wall is 640w to get the output of a 1,000w HPS?
How does the thermal output compare? Would it be similar to a 600w HID or less?
This stuff is fascinating.
If he's smart he'd spread them out over a 5x5 and give himself the opportunity to pull even bigger crops.
No, they're capable of 900 watts, so at 650 watts they'd be running cool
Check with the HLG guys about maximum wattage with and without the use of heat sinks.
150w per board according to HLG's site. So 900w across 6 boards should be no problem?
