(new neighbor here) I can put in a 'plug' for the QB120s and 132s I've been playing with...
I just found that if your Sativas get too tall on ya, They WILL survive ,and finish out OK,with just an inch or two of clearance to the diodes...
IF I dim them down to half wattage...., and they haven't gotten damaged from the close lights...

Ive been digging thru this thread for a while and may have missed the answer earlier but whats the difference in the 288 to the 304 and which is better.

I understand that the 304s were the 'original' 288s...Before they made them more 'efficient'...and used fewer diodes to make it into the 288 version...

The 304s use LM561C diodes
The 288s now use LM301B diodes
The 288s are now more efficient than the 304s

They both use the same LEDs but the boards are wired differently. The 304 requires 108 volts and the 288 requires 54 volts, different driver selection.

No shade on the 304s ... they do the job too.

My 304 prototype light that I've had since before QBs were available to the public still kicks ass.

Budzbuddha · Oct 4, 2018

Exactly.... the 304 I added to that center panel was a S5 bin and it with the other two still grows like a champ. I would tell anyone ANY OF HLG QBs will be a step up. From the 120s on up.

The 304s are priced to sell and make a great build. I mean with the right heatsink and driver you can run a 304 up to 150 watts per board , run 2 Meanwell 320watt drivers PER set of two and spank the shit out of a lot of lights. Plus be able to run each independent and or together.

As far as longevity.... I have been running daily since dec. 2016. ( 304s )
18/6 ... 12/12 whatever the schedule ...... no probs. I just don’t run max.

Hoping for a UV board .... come on @robincnn and @Stephenj37826
Puck ?

Thanks man my first board and Plenty to run so I’m stoked

raymont · Oct 4, 2018

Thanks all. I immediately went to the bigger number is better mindset. You saved me a headache. I pulled the trigger and got

Horticulture Lighting Group 260 Watt Quantum Board LED Kit V2 2700k. Finishing a scrog in my 3x3 and will use this new one. Will buy another and start up the 4x4...Stoked....

Who sells them?

maxlev · Oct 5, 2018

HLG on amazon
not currently listed but they do occasionally appear "very briefly" before being snapped up
if you really want them, I reckon you need to be very cunning
https://www.amazon.com/s?marketplaceID=ATVPDKIKX0DER&me=A8OJ7VEXHXR8S&merchant=A8OJ7VEXHXR8S

Voltage 110+ vs 54....the qb288 V2 can be ran up to 5 or even 6 in series QB304 is limited to 2 due to the molex connector voltage rating. The V1 288 and 304 utilized Samsung LM561C where as QB288 V2 utilizes LM301B which is currently the most efficient white light led that I know of.

That's already in the works. Similar to the HLG 35 red supplement board. For real UVB that is proven to increase potency look at Sola Cure bulbs.

I'm interested in this ,and I would love to replace the big 'ol 4 ft fluorescent fixture I have now using SolaCure bulbs in it...Something a little smaller and more 'streamlined' WOULD be nice !
