Lighting Finally building my COB

[budelee]

Hey everybody!! I am jumping on the diy train with the rest of yaz!! I'll try and document as thoroughly as possible so that if anybody has a build in mind,they can see every part of the process,first off if it wasnt for @BigSm0 @arty zan @pop22 @The Elvis and @Ripper coaching me i prolly wouldnt have taken the chance,..i started slowly with getting the frame pieces cut,i chose to go with angle iron rather than aluminum ,its all good.. Grandbaby wanted breakfast so i hadda take a break

since my light will have 10 1812 cobs i am making the frame 4'4" x 3' and the spacing of the cobs in each bar will be 12" apart giving good coverage for a 16sf area

with all the parts layed out,i see i forget one pack of screws,so ill be heading back to the store

upon inspection of the heatsinks,i found some damage,one broken screw and one bent...the bent screw was carefully backed out and reinstalled to follow the existing threads...

the broken screw took about 20 minutes to drill and rethread but issue fixed..ill keep adding to the thread as i move along

I forgot to add that this will take the place of the HID MH lamp which has a set footpring area of 16sf

Nice setup. The 1812 is a 50v cob. The drivers in the pic is 48v not sure if that driver will work with your cobs? I think you will need the hlg-185-54 for 54v. For 5 cobs on each driver for 700ma each.

Heres a spec sheet for the 1812.. This is the setup most are using,i hope they work. @Ripper @arty zan @AJrexxx got anything to add?? I am the furthest from knowing anything technical about these..

I have 4 1812's running right now they work fantastic. My only concern is you using angle iron instead of aluminum I will caution you to watch the temps on that.. my aluminum gets pretty warm..

The min volts is 47.8 .. should be ok but my concern is how many cobs it will run. I have 4 on my driver.. let's get @pop22 in here since I am driving I can not look very good..
