Hi Guys
Preparing these for July. Will have TK put up some performance data


These will house our new 272 boards with the Cree XPG-3 660nm and new Nichia 757H series, were hopeful of >3umols/j. PCB arrives Monday for loading and some testing

Mate that assembly looks like sex on wheels!! Nice bro

Yes really happy with these, sex on a rope, if this doesnt get you hard you need HRT
cheers

Cutter has the spectrum up on IG and its real sexy.

I will test these up once Mark has them ready, it will probably be next week some time

I'm really interested in the boards with the xpg-3 supplements. I have a friend I'm meeting tonight who asked me to figure a solution for 8x8, which I imagine would be 16 boards? I would like 4 pieces too, for a total of 20.

My only problem with the QB format is I have no idea on where I could get heatsinks shipped in, so I'm wondering on 2 ghetto solutions to stay true to my style.

How hard do you think 4 of your 120w boards could be driven if I just stuck them on a 3ftx3ft or 4ftx4ft sheet of aluminum? Would a 1-5w fan on the rear of the sheet change much?

The other makeshift solution I can think of is that I found 0.6mm thick alu l-bar (30x30mm) that I used with strips successfully. I use two of them per strip, to get a 60mm wide heatsink with two 30mm fins.
Maybe I could just make a 'bed' of L-bar extrusion on the rear of the QB's, and their surface volume would be close to a QB heatsink?

I'm in Finland so I imagine shipping the boards themselves would not be that expensive.

thoses board should be amazing with some nichia optisolis 5000k + the new nichia 757h 4000k + your new cree 660 + 730
