Re: 8 x 4 space - Looking to replace 4 x 315w CMH
:roll: :D Thanks mate. I'll update with some pictures now it's all finished and set up. If anyone knows what sort of volt meters I should get so I can see what the watt / amp / volts the cobs are using as I'm going to be using potentiometers to dimm. Do I get the a.c. or dc versions ? ::: edit ::: A...

Re: 8 x 4 space - Looking to replace 4 x 315w CMH
I'm also looking for options for adding 4 more cobs to each array, and not sure what would compliment the citizen 1212 3500k's. I was going to add more at a later date, but thought sod it, do it while it's down. Do they come in 3000K? Just add 4 more 1212s in the different colour temp? Or you could...

Re: 8 x 4 space - Looking to replace 4 x 315w CMH
So I mounted the drivers to the frames, these things are sturdier than I thought they would be., damn heavy too lol. I'm going to mitre some angle to cross brace the corners, and put some fish eye bolts in each corner. http://i65.tinypic.com/23wvdea.jpg I'm also looking for options for adding 4 more...

Re: 8 x 4 space - Looking to replace 4 x 315w CMH
Well I've had delivery and made a start. Pretty much done the fabrication, just drivers and cobs to go on, then wiring. I have 2 questions though. I want to add some of the digital LCD volt meters that I see people adding to their builds, can I run 2 drivers through 1 of these ? I Got 4 x 100k poten...

Re: 8 x 4 space - Looking to replace 4 x 315w CMH
Thanks for the replies mate, been a bit slack on responding due to being on night shifts. Wake up and it's dark, go to work and it's dark, rinse and repeat. The missus hasn't got a clue what I just spent and thinks the over time I've been doing is to go towards a holiday, little does she know I'll p...

Re: 8 x 4 space - Looking to replace 4 x 315w CMH
swapping watt for watt with cmh, they will CRUSH it!! 600ish w per 4 x 4 is the avg recommend by most LEDers.... over kill would be dumping like 1000-1200w in that same space. frame wise I use a 4x4 frame over a 4x4 tray/scrog in a 5x5 tent.. I'm assuming your shooting for somewhere around a 3x7 ca...

8 x 4 space - Looking to replace 4 x 315w CMH
Hello folks ! I'm about to embark on my first DIY Cob build, and I would like some advice before I pull the trigger on my purchase. I have an 8 x 4 tent that has a 10 pot modular flood & drain system, with 4 x 315w CMH's in 2 x dual bulb air cooled hoods ( Raptor 8" ). As my space isn't ideal for ex...
