Introducing CobKits.com - specializing in DIY and Citizen COBs

just to expand a little bit, i had a few of those around in an industrial environment for 24V alarm/signaling, so i thought they were cool. so i bought a 400W one to try to run a 3618 light engine out and it wouldnt light it. more like flash>click>flash>click>repeat. it couldnt provide stable voltage even though it was in spec.

i actually have the real deal hlg480-3500 coming this week so we'll see whats up with 400W cobs

Which heat sink are you going to run it on? Do you have a Coolbay Tera laying around? I know they can protect it over 450 watts. Can't find the graph right now.
 
What's up everyone. May have been addressed already but does any know when
Citizen CLU048-1212 90CRI in 3500k will be available?
 
some cobkits grown nuggage. looking dank as hell and super dense under the COBs. the colored nugs are exotic genetix "future" all of which hermied and pollinated the rest of my garden. the single stick SOGling is an ethos collective blackfire. i lost my mom for that plant but i took cuts off the flowering ones at week three. if they dont take i will pull the flowering plant out and reveg i like it so much!

as i said before, next on the agenda is air cooling everything to save even more heat. looking great so far! the layout is perfect. gonna order my aluminum sheet to replace the glass tomorrow. i should have an air cooled garden within the month. i'll build the first one to test and them replace the others. another benefit of going this route is that since im running less COBs per sq ft i can build more air cooled fixtures with my same amount of gear i already have.

i could run 3 hoods over a 4x8 instead of 2 and get amazing coverage or i could run two and crank the wattage. let me know what you guys think. in one direction they are 10" on center and the other direction they are 13"
