Help hacking a perfect sun COB / optic 6

[Jolly Green Giant]

I was looking thru that list and remembered one way that was easy to do and use reflectors and and holder..

3 3000k 90cri chips.. 3 4000k 80cri chips.. the V 18 is the same exact size as the 2520( 24mm to 23.8something mm ) with the same V and ma(test current was 1.17 your running 1.2) and the holds to mount and the les( light emitting surface) is roughly the same

9 something a chip plus a good amount of thermal paste ( that's normally one thing they skimp on and causes stuff to burn out) isn't to bad for a quick chip flip that you know what's in it..

Seeing you paid in AUD maybe www.cutter.com.au is an interesting site.

bah I hit the back button just as I was finishing typing!!!!! stupid giant fingers on a tiny tablet!

first off...great info and pictures.. you got what we needed . yes more than likely it's 1 driver per cob and 1 driver per epistar cluster ( 2.5v ish x 16=40v) with the smaller two for the fans.. and as LG said the range is great for 36v cob options( there's a bunch) we normally say 36v cobs at 1400ma = 50watts ( V x A = W 36x1.4=50.4) so your right were they need to be for driver power.

you might have to take out the heat sinks to clean them off.. ( It can be easy or hard depending on how much stuff is in the way.. you might get lucky and can leave them.. or you might have to gut everything to get them out)

I can't tell what chip that is in there... real Cree cobs have the model number opposite of where It says Cree.. to blurry for me to read.

keep asking questions.. it's why we are here my other post before I back buttoned it was longer but I can't remember what else I typed 45 mins ago stoner memory..

on this link should be 95+% of the cobs that will fit your drivers from Cree... bridgelux(Veros)...Citizen and luminus.. I did a search of 31-38volts and max current of 1.6-3amp( basically everything that would run 75% of max power on your 1200ma.... down to maybe 30% of the 3 amp max cobs) with 80/90cri and 3000k 3500k and 4000k CCT. when sorting thru I would look for highest lum per watt for the lowest price and this is just one place to buy parts... there's a good list in the general tab under where to buy parts

Thank you so much to everyone in this thread.

Not only did you help, you quickly gave me Multiple options and explained everything so clearly I think I understand a lot more now.

You guys are awesome.

I'm glad there is a forum with such knowledge and willingness to help that I can be apart of.

I'll keep you posted when I buy and install the new chips.

It looks like there room for a bigger LES in the optic, so I think my options are larger than I first thought.

Thanks again.

Anyone know how those drivers are all wired together? I build computers not lights. That's changing though
I'm assuming it's similar in that they're all drawing from a single power supply like a 400, 600, 750 watt box etc. Anyone know for certain?

The input of each one of those things takes 120VAC so I would assume they’re all tied into the input that comes in from the wall
