Cob + board hybrids

[astonehead]

Is there a thread already for this if there is can someone link me to it please if not can I see everyone's hybrid builds please

Bump, I've been seeing these cob/qb hybrids popping up on the internet. Do these two technologies mesh well together?

 

[astonehead]

This is what I'm trying to figure, getting some inspiration and generally wondering what sort of wattage to run boards when running with cobs

@CobKits @Stephenj37826

What do you guys make of these hybrids?

2nd one looks good with the veros if they are Cs

first one id prob just push the boards harder or add a board or use different cobs as (3) 3590s run that hard arent super efficient and are prob more expensive than doing the same with boards

Interesting , looks like gromau5 is starting a new trend. I wasn't sure if this was going to be effiecnt, but looks cool to build.

I need to redo mine to fit better over a 4x4 space it's abit small, but with 9 cobs 4 boards

thats a lot of light! i imagine youre turning the cobs down. the 9 cobs are about as efficient watt per watt as the 2 boards so they would prob give the most efficient light when total cob watts = total board watts

That's so fucking sick.

Specs please. Will this be your first run with them

Nice what spectrum are you running both Qb and cobs ?

 

[astonehead]

Cobs running 100w between each bar of 3 and the 100w through 2 of the boards so far, 3k 90cri on the 3590s and 35k 80cri boards as is boards @12 inches 50000 lux cob at 30000ish

 

[astonehead]

And just doing some autos getting a feel and then got some more hoots ready to flip when done

Par-Horta will custom build these units! Just send James an email and he will give you details and price. He said my unit has room for 4 QBs if I want to add to it later.

All over the place 3k and small bits of 3500k in the strips. 3500k and 4k in the Cobs.

Iv re done mine again for now until I get more heatsinks for the boards and a bigger frame or just one big alli sheet to attach everything to.
One thing I did notice with these 3500k Samsung boards is that on 20w per board they look much more white although this could be my camera as I couldn't look at them.


And at 44w a board, 177w from the wall between the 4 quick blast test as only 2 on heatsinks



I'm running them at 35w a board so 140 at the wall.

They seem to fill in the dark top as the cobs seem to leave a dull look I think more due to useing 3000k cobs at 35-50 w each

Nice can't wait to see this thing in action.

500w at the wall

Hell ya that's bad ass man great job

Do you guys keep distance the same with boards and COBs? From pictures yes, but... is that optimal?
