CobKits, this is what has me confused? Does that mean you get a better preforming chip with higher light output when run at those wattages, and how does the amperage play into it. CLU-1818 is a nominal 50V COB which can operate up to 4.14A max (approximately 250W). Best efficiency is seen...

Ok people, The last week, I have been trying to nut this out. Is it at all possible to get some confirmation that I am on the right track. 3x3 foot squared area ideally is 9 cobs. I have a " thing " with odd numbers, so I am thinking 8 cobs running on 2x drivers. two rows of 3 either side and...

Thanks heaps for that Thanks for that, that actually helps a lot. I have had a look around, kingbrite was my first stop. but that opens up a lot of options. I have found myself doing is exactly that, I opened up a note on the laptop and when their was something I needed for later I did pause...

Excellent, thanks for that. I priced up 16 units, but that was with the crees. with the savings on those chips may just work out pretty good. Even if I place bit by bit as in get the heat sinks, holders all the bits and pieces and then jump on the chips last. That will give a bit of time to get...

@CobKits What would be your recommendation for a 7 x 3 for amount of cobs and amount of drivers to run at a reasonable rate without putting to much load on everything. In simple terms for a average like myself. The computer analogy made sense. I am currently rewatching growmau5 channel as I...

Hi guys and gals, This is my very first post here on RIU, so I will introduce myself a little and ask a couple questions at the same time if that's cool. From Australia, and the laws are starting to crack down. I have grown in the past umpteen amount of years ago, and came undone ( due to my...
