Yes, excactly the kind of info a lot of users need. Keeping an eye on this one. Thanks in advance cobkits

Having cooler cobs will increase efficiency.

Got the same light and its rocking hard. Love the very even spread. Hope you post some more to let everyone see what that light can do :)

Got contact in china for custum driver. ordered 5 of them and really impressed with them. Runs much cooler then the comparable meanwell. Guy is really great just send him the datasheet of the cob you want to use and how many and he will make the driver fit those specs. sales16@brightstarleds.com

Maybe more powerfull driver to get some more light? Seems you got the basics to get a light going.

You could look at tme they have some options

Where can i check this out? Looking into an arduino control system to control dimming of multiple light sources.

CXM 22 looking very nice. Might consider them for my next build. What do you guys think about seoul chips? http://www.seoulsemicon.com/_upload/Goods_Spec/SDWx7F1C_ZC100_datasheet_Rev3.1_161110(0).pdf

So today i have been building on the light and it is shaping up nicely. Only one concern at the moment when i wired all the fans up in parallel 1 of the fans didn't move. I checked it with multimeter and it does have a complete circuit. Could it be that my driver is not strong enough to power...

Try the citizen led calculator. Gives you fv at different currents.

Yeah, this was about the max. Can always dim when needed. Light will be used for veg and early flower. Couldnt figure out what efficiency i would get when i run this flat out, anybody got some estimate?

Hey guys, Finally got my parts together and wanted to show it here to make sure i am not overlooking anything. Will be building the light shortly. Planning to use 2 * 3000k and 2* 4000k in a H shaped frame. Wil be placed in a 90* 90 * 180 cm space. Want to run them close to the max of the...

Use the citiled calculator for your current

maybe for some mono's?

I think it is not the best. It is not the top 3500 k of the citi line. This one has lower output then the normal one. The normal 3500k efficacy 152l/W, but the one you orderded is 119 L/W. The chip you bought is under BBL and i would advise getting the same chips in 3000k and 4000k from the...

True, have seen a lot of fire from fem seeds. I just don't like the reciprocal buying of seeds. Also pheno's tend to vary widely. Would be better having a good cut to take clones from. This has a better stability and helps me getting the most out of a strain

You could also take a look at the CLU048-1212. They go cheaper in the EU then this nicha cob and they have just a little more lumen/watt. But would love to see how these nicha's perform they have a very different spectrum to the CLU048.

Thanks man, will be watching this seller. Always good to find resellers closer to home.

I am also planning to build a 1212 rig and push the chips hard. This is my choice up till now: http://www.sicomputers.nl/alpine-11-plus.html Should have a little larger mounting service and more cooling capacity, also bit quieter but also more expensive.
