I upgraded a Roleadro. Just switched the cobs with clu048 1212 3000k, was easy and the cover fit back on without any mods.

I only used it for a week! lol. Then it got switched out for a DIY cob light. Then I upgraded the Roleadro, still havent used it yet though. To answer your question though, it worked fine for the time I did use it and the girls responded. Even with their crappy chinese cobs

The bridgelux vero is a top quality cob.seen a few guys hack the roladro box with better cobs.
Have you looked into the quantum boards at northern grow lights? Sounds about perfect for your small tent.they have a single board kit that is 1 board,1 driver,1 heatsink kinda plug n play and these are very bright boards with top bin diodes.i have 4 here and just plugged in 2 of them to see how bright they are and i was amazed at the amount of light these things put out.

just out of curiosity, which driver is it that comes with that single 90w board kit?

LMAO I had that same thing open on another tab, great minds think alike!
I'm going to see if I cant find the parts(or their equivilants) myself and get it a wee bit cheaper.
Of course unless its all on amazon or something with free shipping, it would probably be about the same if I sourced the parts from 2 or 3 sites. I guess we shall see!

The 90w quantum kit from ngl is way more efficient and brighter than that rapidled kit.

DHgate will have the best prices but you have to wait for international shipping
I bought an Enail from there for about 1/5 the price of other places

nice. I like the full spectrum cobs too. 50w or 100w. four 50w cobs 30-32v can run on am neanwell driver HLG-185H-C1400B for 200w setup. low cost and you an use the heat sinks and fans and put them in a frame.

3x 1212's ($15-20) driven at 0.5A each on the 140mm pin heat sink $20. HLG-185H-C500a $50,
total inclidung miscs should be around $100 per engine. I'm not exactly sure, but I'm under impression that this engine has 50%+ efficiency. If you scale up - you can fit 3 engines on this driver and that will be $73 per engine and that what I build when I had extra PIN's laying around. If you want dyi - ditch cob's idea - F series gen 3 is the way to go now for less $ and better efficiency and coverage.

So what would be the suggestions if you had say $1k-1.5k to work with on a diy?

20xf564b with 2x 480h-48b 20x1" heatsinks around $500 + $200
Now double it for $1.5k
20 strips at 1a will cover 4x8 very nicely 950w). 2 of these strips equal exactly 1 qb288 just to give you an idea, 20 strips is equal to 10x qb288 :)
