Can confirm that these new boards feel considerably more solid and durable. You can easily tell the difference if you're holding a new board in one hand and an old one in the other. Also, that is a kick-ass machine!
Somewhat. Thought Scotts co. wanting to make further acquisitions in evolving herbal scene. Hawthorne already has Gavita....Lighting good move for Marysville company !!Scott's as in Hawthorne?
Have you ever run a spectrum analysis of quantum board 5000k and 3000k mix ? also 4000 and 3000k mix ?Making QB 288 3000K in USA since October. QB 288 4000 next month

I've been running 2 qb120s in series off a hlg-120-48b. Works great for me. I posted this pic a few pages ago, but here it is again...Quick question .... Can the 120s ( pair ) be daisy chained ( molex to molex ) and powered from one driver ... If so which would you recommend ?
Looking at throwing my 4 288s with dual 120s in center .... Run the 120s for early stages then full rig power for rest of grow .....
And will Amazon get supplied as same time ... Stock says unavailable.
Still wondering about all the discussion of spectral mixing on boards and strip light combinations. Guess no one
It doesn't help that's why no one does itStill wondering about all the discussion of spectral mixing on boards and strip light combinations. Guess no one
combination much better than another.
I feel a combination of a large white light source with targeted spectrum bands for supplementation will be how led will replace conventional lightingStill wondering about all the discussion of spectral mixing on boards and strip light combinations. Guess no one

Yes, that can be done. As long as both run ok on the same current. If one requires a higher current level than the other then its not going to work well.I am wondering if it is possible to run 2 boards requiring a different forward voltage to the same driver in series.
For instance, is it possible to run a qb120 (24v) and a qb132 (36v) in series from the same driver?
Is it just a matter of total voltage?
in 10-14 daysIs there an official release date for the qb132's????
Most of the Amazon stuff has "Currently Unavailable" listed.. Thanks
Post 2 on this thread. I tried the same heatsink and it got hot. Fins too close and it did not help much with cooling.Fired up my 4 qb 288's last night for their first day. I did a DIY build so each board is on a separate Heatsink. This is my first time ever using LED's and the top of the heatsink got ALOT hotter than I would've imagined. I lined up the ducting from my 8inch inline hurricane fan so that it was blowing across the top of heat sinks the best I could but even with that I could hold my hands on the heatsink for about 3 seconds before it go to hot. Is that normal?
I bought my heatsinks from Heatsink USA. after waiting for over 2 months for them to come back in stock at HLG
The machines we had (I think they were Samsung?) at the company I worked at from 2000-2010 worked a bit differently. The placement head was stationary and the machine moved the PCB around under it as it pulled the parts off the reel. Population speed was 2-5 times faster than the moving head machines they replaced. For a single part board like the QB288, it could build it up in about a minute.Making QB 288 3000K in USA since October. QB 288 4000 next month
The pick-up head was actually a disk with either 8 or 16 (I can't remember which) vacuum operated pickup points, and it spun around, picking up a part from the reel, and rotated around to place it on the board as it moved into place. So it was actually holding on to several parts at all times, even when it changed to another reel. The reels were on a moveable rack, and it just moved the next reel into place as it needed. The thing was wicked fast to watch, especially when placing a lot of the same part close together.The machines we had (I think they were Samsung?) at the company I worked at from 2000-2010 worked a bit differently.

No problem bro. We all have brain freeze-ups now and then.lmao I must've been high when i wrote that
thanks for the correction partna
