That could work although I want to make some 2 board lights for friends with spare sunboards and fusion boards I have. Let me know how much and where, could work for my 9 cobs

cant think off my head but what driver would I use for 2 36v boards to run 75w? I’m thinking 185-1400 but not sure il get 75w with out a 2100? Any help so I don’t have to sit and work it out would be great

Flooded out? What are you on about? Because I just watered and didn’t take out the runoff whilst I took a quick picture! Ffs come on lol, always someone trying to pick at something!

So 2 days since I flipped these we have some decent growth. These lights are great I like them

A little update on these lights. I decided I was getting such good veg growth I put all the babies under this light and they have grown so well they are all going to be flipped tonight, these are testers except the clone at the back so not sure what will happen here And the plants are...

Thanks for explaining that, the boards are pretty inexpensive anyway and pretty intense, I only use cc drivers and have over 320w available at the wall with 4 boards on a 320 c-2100 so all is good, iv only got them at 200w and with the cobs it’s 705w in the 4x4 :)

I don’t use the reflectors at all to be fair I find them too intense

I got myself 4 ish150301H boards aswell to replace my Chinese boards that do pretty well, hopefully yield stays up and quality should improve as well, just need to get the light down which is not easy at day 40 of flower :D These will join 8 cxb3590 and 1 vero 1750k. So my whole rig except the...

If that’s what they said I can’t see it being wrong

Guys any concerns just drop a message they really won’t mind, they are so helpful I just ordered 4 150 boards with the 301H can’t wait for them to arrive

These are doing pretty good even just in veg, growth is good and plants seem happy and drinking well again. No complaints here. Back one is a clone from my jaffabone f2 I’m flowering and front is a bloody berries tester from bud doctor from seed

The answer I got was is that the resistors balance the current equally across the strings, it ads longevity to the diodes. So was a good guess

It’s in their boards as well so as you say probably just a sure to be sure lol, il ask him

From a quick read is that saying it’s not a bad thing? I did wonder why invisible sun use them but hlg and others don’t, I figured they could save losing a string of diodes maybe

Let us know how you get on

I believe they keep each string exactly equal so in a way would help I suppose. Drop them a email you will be surprised at how open and helpful they are. I want to buy 4 boards but I can’t take my other light down for 4-5 weeks so not sure what to do, don’t want to buy something then change my...

Oh and I hear they are bringing out some other boards with red and far red aswell. I can’t wait to see them as may be my next upgrade

Turns out if I put a little fan above them just to move the heat the temp drops down to about 30* but lower when the temp drops at night. I don’t think 1400 would be a problem at all like stated on these

The map is in a 2x2 I have them in a 2.5 x 2.5 but would like to run them in a 3x3 if I can push it, also so I can run abit higher maybe, I don’t know why I want to run 2100ma lol Yes running at 100w whist still vegging

Currently running 100w at the wall and with a metal probe on the back of one strip it’s reading 35* I can’t feel any heat, once I flip I will know, I want heatsinks though so I can run 2100ma
