Kingbrites SUCK! *Insert racist comment here*
2x LM301H + CREE 660 + LG UV 240w switched.
2x LM301H + CREE 660 + LG UV 240w switched.
Been reading through this thread and only made it about half way... a lot of great info here ... but about all my head can take in for now.
Ive ditched the idea of buying lights with the IR and UV built in as Ive seen some of you suggest they have a shorter life span and I would be better having my bar full of whites and reds. I like the idea of supplementing with independent deep reds (IR) (and maybe IV) anyways and then having them on an independent timer.
Now ive got myself a 4x4 grow space. I have been thinking I want two independent light rigs so I can adjust height independently depending on variation in growth. So two of the 2x4 rigs to cover 4x4.
But I cant choose out of the quantum board or the quantum bars from kingbrite.
Anyone got some recommendations? Also, are the red CREEs worth the extra coin?
Two of these 2x4 bar set ups:
Bars seem like they would give optimum spread + they got the cree.
Orrrr for QBs I would purchase 2x these that have cree.. and the boards can be moved indepdently. So would end up with 4 separate boards
Or buying two of these provides a total of 6 boards! Boosting it up to 640W total power but they are using the epistar and not the cree (the cree model is too expensive)

Imo yesCree or epistar? Is cree worth the extra $35USD?
The IR is worth it the UV isn't imo. If you want UV better to go with a UVB florescent. LED UV diodes are extremely expensive for the proper ones. I can guarantee these are not of that qualityMmm so i have to find the right 240w with cree now :'( Another 2h browsing for the right one incoming haha! Thanks anyway for helping us!

H is slightly more efficient.Thanks Aqua man.
Now just to confirm, and I think this will help others who are digging through the end of this thread.
LM301B and LM301H are essentially the same just the 'H' designates horticulture lighting
660nm red is good to have throughout the grow cycle from start to finish as it promotes photosynthesis
730nm is IR (or far red) also boosts photosynthesis but IR = heat and ideally is not run for the complete lights on cycle, so being able to switch these independently and have them on their own timer for a shorter cycle is desirable - these diodes also have shorter lifespan then LM301B/H
UV may help with resin content but it is still inconclusive. They probably help keep pests away - these diodes also have a shorter lifespan and are less efficient
Please correct me if I am wrong
Hi!
New to the forum and joined to chime in this wonderful discussion. I am new to quantum boards and was trying to figure out which one from Kingbrite would be ideal for my 4x8 room.
I am debating between 4x 240w or 2x 480w for my 4x8 room. Then there's all the different model with Cree/Epistar, UV/IR , without UV/LG, QB288/QB272 and so on. It's very confusing. Anyone with experience with quantum boards could give me some insight?
Anyone have an idea what would be ideal for a 4x8 room?
Ty for the help!
Strips are better imo.Alright, Ive changed my choon... maybe.
What if I were to purchase 8x 560mm strips and 2x 240W drivers. Make 2x frames at 4x2 each to cover my 4x4 space. Each frame would hold 4 strips and be driven by a driver each. I could then buy 4x 560mm IR booster strips to supplement throughout and run them interdependently from a 120W driver.

Only works out to be slightly more expensive then buying the complete kits. Allows me to experiment with supplemented 560mm strips (IR, UV, blue) and control them independently. Ill also build the frame so I can indepentantly move each strip (have them on rails) so I can completely control where light is.
Then if if a strip fails I just need to replace a pretty inexpensive single strip or a 240W/120W driver.
I also don't mind a DIY and do have a fair bit of electrical/fabrication experience behind me
