Run the 3 off the 600 and grab one more on 185A (true watts closer to 200) and you have ideal coverage. 2 of em do great for a 2x4 area. 2 veg a 4x4 very well. I was saying the 600 isn't a great choice if you added one more fixture. Those can handle well over 150w each. Putting 600w in a 4x4...

That 600 is underpowered for 4 though. Hmmm.... I've been running each elite off one 54v 185A meanwell. So they get about 200w. Works mint and provides all sorts of flexibility around the 4 288 v2s running off the 600. I started in a 4x4, now onto a 4x8. I would recommend spending a few...

Get a 4th. You are going to have coverage problems with 3.

Better penetration on the 96. Thinking of mixing 4 of em with the 288s to run a 4x8. The 288s solo didnt do it for me. So i went for more light and some red to boot. I dont have a ton of time to be putting together strips, build a frame, etc. So the hlg board+hangable heat sink were a simple...

I believe thats what we came to about a week ago. Admittedly, i don't know much about strips and their power reqs, but iirc hes running an hlg 320 2100? Again, i don't know a heck of a lot regarding COBs, their efficiency ranges, etc, and as far as i understood, i thought mixing even the same qb...

Something like the sammy strips. Theres a million things on alibaba, but given its china YMMV.

So it looks like the elites are out. They recommend 320-2800n rather than 320-2100 on the elites. The 240-2100 would be ok though? Honestly, your beat bet might be the cobs mixed with some strips/boards? Get some red in there and use white strips/boards to supplement around the "hot spots"...

Not sure, think i read its some newer tech sammy was working on. I believe i saw pics showing multiple diodes per unit? So each chip really had a few diodes pumping out light (im sure im butchering the explanation). There was definitely a magnifying glass used to show the differences...

So youd be running 2 drivers per 4x4? That should be about perfect if those drivers will link up with the elites alright. Somewhere, someone posted all the mapping on the elites. 2 per 2x4 or 4 per 4x4 were more or less perfect. At those wattages you should be running nice and cool as well.

The qb96s do a great job mixing the best of both worlds! Plus being able to run up over 200w passive...cant wait to build my room and have some real space to experiment with. 288s, 96elites, cmh, hps all laying arpund right now. Who knew this mj thing would really turn into an obsession with...

Pretty sure the 2100 could run 2 elite v2s in series and be fine. Check out the recommended drivers portion of hlgs page to double check (i run their other drivers, cant remember which cc drivers handle what). What size space are you filling? Iirc that would rock a 2x4 no problem.

Not sure what color temps are in stock, but he certainly could change the spectrum with elites...a more negligible change qould be different color temp rated boards ckmpared to whatever he has going on with cobs. The larger footprint of a 288 for example means less of a focal point, therefor ypu...

Keep in mind a 240 type a can really push about 250-260w maxed. The type a drivers from hlg can push 5-10% more than they are actually rated for. Its the reason a 48a can max out 288v2s but 54a/b is needed for the 288v1.

Spectrum? Coverage? If anything I'd say adding qbs to the existing COBs might make sense? Cobs over each plant, qbs as side/filler lighting between the cobs? The new 96 elites are more pr less a combo of the ideas between the spacing of qb boards (288s, 324s, etc) and not needing heat...

What drivers are you running?

Leds typically bump up the cal/mag requirements. Check ph and ppms, make sure everything is kosher there. If anything id say the lights are too far away from those lights, not too close. Ive always kept my leds within 2 feet, as close as i can get them without seeing bleaching. Also, ive never...

The 288s are the lm301b if memory serves. Theyre the v2s. Interesting note on the v2s, if you buy a type a driver, you can get away with a hlg 48v type a driver (check out the tables, they max around 49v iirc, so the +/-5% of max covers the draw necessary! It fails to cover the pad hlg...

Reds are where its at fellas. I was running 4x288s off a hlg600 and slapped a 96elite on a hlg185 and threw it in there. Holy shit. The 96 is more or less centered (knew i should have ordered more while they were in stock). I run 4 plants in a 4x4, 30 gal no til homes for each. The buds in the...
