oh u showoff try two feet and get yurself a lux meter! or even better a ppdf meter, but those cost $$$ *edit its going to be hard to set a lower power and height without a meter.
I’ve read through alot of forums but see no real answer, are these copy boards any Good and has any One testen them in comparison to a hlg. Which of these suppliers can be trusted. Kingbrite Qb288 Board,Samsung Lm301b 660nm Quantum Board - Buy Qb288 Board,Kingbrite Qb288,Samsung Lm301b 660nm Product on Alibaba.com Or QB288 V2 LM301B PCB for plant grow lights, View PCB, HS Product Details from Shenzhen Hansion Technology Co., Ltd. on Alibaba.com Or R2t 120watt Qb288 V2 Led Grow Light Hydroponic With Samsung Lm301b Sk/sl Bin For Indoor Garden - Buy Lm301b,Hydroponic Grow Light,Led Quantum Boards Product on Alibaba.com
I can vouch for Meiju, I think others here like Bava too. I like the boards... as everybody else does. Kingbrite is authentic, Hansion is authentic (but pushy), and I never looked at the last one. cheers
Thanks, trying to gather as much info as i can before i pull the trigger. Would be nice to find a test between them.
I have the older diodes (the V1) and they are great. I rarely run them at higher strength. I like the boards much better than the COB style as the light dispersion is better; can just turn down the power and bring the boards close, but with cob styles (or HID) if you tried that , it wouldn't work. From my research, BRITE was the cheapest (not Kingbrite, just BRITE), but maybe using older diodes (?) Bava has some nice red 660s incorporated in their boards, so do Meijiu, but in their 800 diode boards which run a 2x4 pretty good.
I can vouch for Bava, at least as far as customer service was. I intend on testing out boards from kingbright as well. Long term is to be determined, but at this point these lights have a 10 year lifespan, so these will be old news before they take a crap.
After finishing one run under 200 watts of big cobs, the temperature difference in tent is now at least 5 degrees cooler with 301b chips. The light spread, and ability to dim is worth its in weed
The boards of R2t and hansion look so good and then there is Meiju or kingbrite. This is gonna make choosing only harder. lol Thanks for tips so far.
For what it’s worth, Meiju has some interesting, larger sized boards that I haven’t seen everywhere else. They caught my eye a little while back.
I’ll be going for 3x3 or a 4x4. For both tent sizes i was thinking of buying 4x QB288v2 on Two triple slate heatsink and maybe later adding two more boards in the middle.
I think 3x288 per 2x4 is appropriate, not wattage wise, but coverage, because you will save power using lower settings and bringing it in close. That's a good thing about the 800 board, kinda is 3x288, kinda... I like your plan, triple heatsink + boards... makes the 800s sexy. 3x3 is harder to light up, but using 4x288s would work. Please be aware that you can just buy some modules too; my 4xL09 modules ROCK and are very customizable. You can get them 1' or 2' strips. I kinda compare the 4xL09 to a stretched out 288. Better to control hot spots that you get with boards (which tend to be too bright in the middle and not enough beyond its footprint). At the moment, I have an 800 board and 4L09 is a 2x4, but I have the 800 turned all the way down. I don't think it will ever go over 50% but I have very nice even light coverage. Here's the thread to my L09 build (which you can buy strips for much cheaper from KingBrite, or Brite): Samsung HinFlux L09 build
I see hlg also makes these kind of strips and there are Alibaba alternatives. HLG SABER 100 My preference still goes to the qb288 V2 style. Had look at this 1,20m x1,20m build that migo was setting up.
I did a shopping from Meiju about a month ago.They delivered the cargo in 3 days. I got it in eight days.They work perfectly and are very helpful. If you're going to get a light from there, take a sunglasses
I had one damaged board from shipping and after a little talking they refunded me for shipping and I was able to fix the issue with a binder clip lol (loose terminal). shit happens but still cost effective and works great. here are my two FOGRO 65w boards which are basically HLG65s except these have 112 LM301Bs @3k and 16 Epistar 660 reds. The one on the left is the damaged one, you can see the binder clip. Sent from my SM-G892A using Grasscity Forum mobile app
