Citizen leds

[giantsfan24]

Just barely over a week into flower. The PPFD is that of a 600w. 270w with fans accounted for. Two of the black, one of the red.

So 181w is light and the other 60w is fans? Am I reading that right??

No. 241w is the light, 270-241 are three fans and three drivers.

 

[Olive Drab Green]

78w of light + 78w of light + 85w of light in the middle. 241w of light.

Got it. Thanks again!

@CobKits Already have the clu058-1825, hlg-240h-c2100,and sst-x sinks just asking if the sst-x can handle the 120 watts passive as running two leds per driver or will I have to dim a bit?

Curious to know the answer to this as well.

@CobKits I Already have the clu058-1825, hlg-240h-c2100,and sst-x heatsinks. Can the sst-x heatsinks handle the 120 watts passive as it runs two leds per driver... or will I have to dim them a bit?

(The quote above was edited to represent what I think "Pulses" maybe trying to imply. Below is the reply....)

With additional air flow into and throughout the grow space... yes. The heat sinks aught to handle the intended light source arrangement. You need to remember the fact heat also transfers into the metal of the mounting frame.

"Remote" mounting the driver(s) will allow them to run at cooler operating temperatures. Which then means your chosen light emitting surfaces are brighter.

2.1 Amps is half power for the capabilities of the COB. Full power is around 4.8 amps.

sorry i missed that question and thanks for stepping up rayne. i wouldnt hesitate to run the 1825s at 120w on an sst-x. it will run a little hotter and dent efficiency a bit vs lower currents but those chips are rated for 105c case temp/140C Tj.

thats whats cool about the 1825, efficiency is pretty respectable at higher wattages. that 1825 at 120W is about where a cxb would be at like 80-90W on ppfd/W. Pushin it but not too much

SSTX is a force. Its hard to recommend anything else for 80-120W

These drivers are underrated 4 cobs with two drivers use 580w at the wall.this unit is a beast turned all the way up

sounds about right. all the meanwells are underrated, i go by test reports not by datasheets
