Yea, I'd even keep the wires from the driver cable/extension (if remote) to the boards the same length. I'd keep all wires the same length.One thought was each loop length to a light should probabley be the same length

sounds very organizedYea, I'd even keep the wires from the driver cable/extension (if remote) to the boards the same length. I'd keep all wires the same length.
I was thinking of order just 1. However I suppose I could use my multimeter. I rechecked the different my drivers on that AC meter and showing as follows.
1 185h 54a powering 2 QB96e pot maxed was255 watts 120.6 volts 2.11 amps
1 185h 54a powering 2 QB288 v1 pot maxed was 256 watts 120.4 volts 2.11 amps
1 240h c2100a powering 2 QB288 v1 pot maxed was 297 watts 120.4 volts 2.48 amps
Using generic "Kuman" ( cheap ) wall meter.
I did discover the 20 amp circuit I installed w 8 gauge wire runs 120.9 v and the preinstalled 15 amp circuit with 12 gauge runs at 116.6 v.
I measured voltage drop when install the 20 amp, and the bigger wire is under 3% and smaller one was just over 5%
You know, I was hoping someone more confident/sure would chime in. You said what I was questioning, and trying to say. Essentially, that this didn't add up. How/why would a 185w driver be putting out the same power as a 240w driver, even considering an 8-10% over boost over rated.its vey likely your watt meter is inaccurate. This driver has over current protection that kicks in at 108% of maximum, which means the driver has a max potential of 201.2 watts before the current limiter kicks in.
Did you decide on anything yet dude?Thanks for chiming in. LM301H from what I understand is an updated LM301B that is supposed to be slightly more efficient, but from what I gather they are both great diodes.
I have been looking at those Rspec QB96 builds. They are awesome but I am still questioning if the 660nm chips are worth it VS a board with only Samsung LM301B or H diodes.That being said If I'm not mistaken all the Rspec boards come with 3500K diodes and then 660nm diodes to balance it out. Now that makes me question if a 3000K board is comparable to a 3500K board with 660nm mixed in. I suppose the latter would have more red and blue like you stated instead of more red and less blue but I wonder how much or what kind of difference it makes.
And these ladies are screaming for the lights!!!Sure hope those lights come this week!!! Especially since I just dropped 5 purple nuggets from Mephisto in root cubes Friday!!! I hope q@Stephenj37826 didn't forget about me!!!???
I did! I came to the conclusion that I would go with straight up 3000K LM301H diodes and just see how that works out for me. Seems like it still has plenty of blue in the spectrum anyway.Did you decide on anything yet dude?
If you have HLG QB's, just get a lux app on your phone to see how much lux you get at plant height, then go here and divide your lux by the number they give you for the boards you're using, that'll give you a rough estimate of ppfd.I need some help deciding how high to Hang my lights in my 5x5 I feel they are too high but scared to bleach them36hbxb-hw first co air handler grow cab!
I will be logging the progress of building my new chamber out of this air handler. I have some other ideas id like to build down the road into this chamber but for now it will be a simple soil grow chamber. Materials: -Bath fan~ 3" low cfm -Small oscillating tower fan ~ need something very slim...www.rollitup.org
Any recommendations I’d appreciate! All the info is on my newest update

@2com @pop22 Pull out the old multi meter and indeed the DC watts to the boards would be lower. About 30 watts lower on average. Measured 259. watts on the 240 c2100 and 228-229 watts for the 185 54a. I am not sure i am calculating the 185 correctly ( parallel ). I am pretty much doing it the same way with the multimeter, point + to point - while load is "on" gives me volts and running the + through my meter for amps. According to the spec sheet this 185 driver should not run this high.
Calculation was 107.2 V x 2.42 A = 259.43 watts for the 2 qb288 3000k v1 240 c2100 series
53.1 V x 4.3 A = 228 watts for 2 qb288 2700k v1 185h 54a parallel
52.97 V x 4.34 A = 229 watts for the 2 qb96e v2 in parallel.
It is cool see you have messed with all of those Kelvin ratings! Were there any other differences you noted between the three like internode length, density, and resin production? If i might ask why do you like 4000K boards best? Thank you for your thoughts.I've run 3000k, 3500k, and 4000k. both the 3500k and the 4000k produced more bud than the 3000k! Not by a lot but measurable on the average. I actually like the 4000k boards best but most of my boards are 3500k and run start to finish.
