I have one of the old skool ones that doesn't have the dimmer box like the newest model does. The 2 drivers have potentiometers on each and mine came from the factory set at 456 watts. The potentiometers allow running higher than the 456 watts I actually had mine set to around 500 temporarily...

Yeah I noticed that with temps. I changed 2 things at once the temp and the medium as they were slightly root bound anyways. Usually at signs of trouble I try and change only one thing at a time it's easier to troubleshoot that way. I was running in the mid 70's then check leaf temp with an...

Why is it that nearly everyone switching from hid to led has calcium and magnesium deficiency??? It's a very common occurrence and I wouldn't really think that the par difference is that great to cause it. Maybe it is the ambient temperature being too low locking out the 2 nutrients??? Any input...

The hlg 550 v2 has 1152 LEDs at 480 watts that's .416 watt per diode. So I do the math on 1212 diodes I should be at 505 watts. That would be the same driving power as the hlg 550 but for the sf4000. That is my max. I should be able to do that ok as these are the same exact diodes.

They do dim but according to the manufacturer they don't dim up. You can tell they need a better Chinese to English translator. The drivers have two potentiometers on them. They don't recommend going beyond the 456 watts that it should be adjusted to from factory. I never took a base reading and...

It's an ELG-240-48A driver times 2.

If I do go beyond the wattage they have it set at it won't be too much beyond. I want this light to last and I was doing the math and pushing these lm301bs too far isn't good for lifespan. 484.4 watts is .4 per diode. That is about as far as most people push them. I don't think I will go beyond...

I was going to see what they have today at home cheapo. Thanks

Nope not even connectors they are water tight junctions in the wiring. It goes from a standard wall plug nema 5-15p then 8 feet of cable to a water tight splitter then to each driver. From the driver's to each end of the quantum board. It's as simple as a junction x2 and extension x2 I just need...

I know I was looking at making stand offs for the driver's to be flipped upside down and making easier access to the adjustment potentiometers but then I was thinking why bother when I can move the damned things out of the area. Those type of connectors I don't know who makes them I guess I'll...

Well sort of. The radiant heat is a completely different animal but the CMH is air cooled and easier to directly pipe out of the area as oppose to the led where it is a bit harder to remove all the heat while leaving the much needed humidity and c02. I have the CMH dialed in and have done great...

I wrote the company and they said to not go beyond the 456 watt draw. I tried mine at about 600 for 10 minutes with no ill effects. It did get warm compared to the absolute minimum that I had it running at. Right now I have it set to about 320 watt and I'm getting similar readings to my 630 CMH...

I'm looking for people using the SF 4000 LED light. The factory settings were at 460 on mine but I'm looking for a maximum that is safe to use without damaging the LED bulbs. I was adjusting it and it would go past 500 watts and approaching 600 pretty quickly. Is anyone using this board??? What...
