QB kits

[Doctor Ledpot]

I like some things about the NL Mega including the footprint, and what I think is the relatively even coverage it affords. Looking into and comparing QB offerings in fixtures and kits; in order to approximate these Mega features, I see, as one possibility, pairs of HLG 320W XL kits, spaced accordingly. I do realize that this approach would be a more costly option than, for instance, a single HLG 600 kit(4 QBs on a single substrate), having similar total input/output. The boards on the 320 kits are apparently driven much softer than those on the 600. Thoughts?

A newb at all of this, and wanting to get off to an ok start with LEDs. Would really like to build a light of my own design, but for the time being, will have enough to do with the hobby itself, let alone a hobby within a hobby.

yeah.. 2 of the 320xl kits would be pretty dang close to the same footprint as the NLmega. I would also assume it's roughly the same diode count.. ( 1728 with 6 288's) I didn't see NL list it.

the hlg600 does push them harder.. since its only 4 they're getting 2800ma each.. which is to close to max for me... 320 kits are pushing just under 2000ma (5.95/3=1983ma) to each.

another though.. buy 6 boards, two of the slate 2 3board heat sinks, the accessory pack, and a HLG-600h-54A or B... depending on if you want to mount the driver remote for easy dimming and less heat=a type or use the driver heat and run a potentiometer out to dim.= b type.

are they NL megas dual CCT? that could be another plus of the kits.. you can mix and match spectrums.

your starting off really good imo NL.. QB's both good starting points... I just love how simple QB's are to use... why I always recommend them to newer people.

cheers

Hey, JGG, believe that we might have chatted briefly during one of the GML shows.

"yeah.. 2 of the 320xl kits would be pretty dang close to the same footprint as the NLmega. I would also assume it's roughly the same diode count.. ( 1728 with 6 288's) I didn't see NL list it."

had in my notes that the NL is 24 X 96 strips (2304 diodes) but didn't note exactly what diodes.

"the hlg600 does push them harder.. since its only 4 they're getting 2800ma each.. which is to close to max for me... 320 kits are pushing just under 2000ma (5.95/3=1983ma) to each."

Well the plus side to not pushing them as hard, might be less heat/an increase in longevity and/or efficiency, right? Or do the 320s run pretty hot anyway, idk?

"another though.. buy 6 boards, two of the slate 2 3board heat sinks, the accessory pack, and a HLG-600h-54A or B... depending on if you want to mount the driver remote for easy dimming and less heat=a type or use the driver heat and run a potentiometer out to dim.= b type."

Really hoping to not get too deep into the DIY thing at this time

"are they NL megas dual CCT? that could be another plus of the kits.. you can mix and match spectrums."

Don't know about that, but the available spectrums in the QBs looked better to me than what comes with the mega,(seemed quite blue heavy). One small plus for the mega is that it's just one fixture to hang, and daisy chainable to boot.

"your starting off really good imo NL.. QB's both good starting points... I just love how simple QB's are to use... why I always recommend them to newer people."

Thanks, and thanks for the response!

yes.. running cooler the better.. efficiency and longevity both improve.. with the slate 2 ( the triple is rated for 325w) style heat sink 2000ma each won't be bad at all... I run 2100ma (110ish watts) with my slate 1's ( only rated to 100 watts).. that's pushing it to the limit with no direct fan on it.. I only got the slate 1's because they fit perfect in the RapidLED substrate. I need to upgrade to slate 2's and make a different frame.. or add fans

and yeah.. I'm always trying to help with QB questions on GML's show sending people here to find more info or ask questions I'm sure a few others have come over... but your the first to mention it awesome!!!!
cheers

Thanks for joining!

These QBs are a great way to get your feet wet in DIY LED since they're sort of a hybrid. The design work is done for you but you still have to built the kit. I have nothing but great things to say about the products and especially the guys that stand behind them. Robin and Stephen are fantastic to deal with.

Thanks, I hadn't noticed, until you mentioned it, that the various slates have watt ratings on them. I now see that the wattage of the 320 kits actually exceeds the ratings for the included slates. Do you have pics of your build, here on the forum?

I like the way that your boards are spaced out...still in the planning stage, but with my available space, looks like my SCROGs want to be about 4X5 each. That being the case, now wondering whether to go with HLG 550s(or clones), 600 kits, or pairs of 260XL kits. The 600 puts out the most light, but a pair of 260XLs, spaced maybe around 10" apart, over each SCROG, might produce a more uniform coverage, lessening hot spots at the center, and providing more PAR in the corners?

[Jolly Green Giant]

yeah.. you would have more uniformity and better corner lighting with two xl kits.. or 4 single heat sinks like mine spread out. and the center wouldn't have the hotspot like a 600 clone..
