Hello Sir, i dont belive, that this unit can cover the same size like a 600 watt hps with the same par footprint. With 600 hps i managed to got often over 600 gramms in a 4*4. https://www.amaretechnologies.com/collections/solarecilipse/products/copy-of-solareclipse-se450-uvb this unit? How is...

170 g:eyesmoke:

wow thanks @ guod, very helpfull for me. I will try it out for sure, as soon i have the materials, i would like to use this method I have a solder iron, i just need to order this parts. They are cheap, i will order some more and train my solder skills.

yes yes thanks @JorgeGonzales can you please check that picture, if that is a correct way to connect the multimeter, i didnt know how it works. I never used it, i watched now a youtube tutorial, i hope i did understand it.

Hi @JorgeGonzales if you have time and mood please help me. i would like to know if i connect one cxb3590 to a ELG-150-54b and then i dimm the cob to 50watt, how high is then the driver load %

wtf :cool::cool::cool: , i love ur grow cabinet:hump::hump::hump:. In future i will build something similar:idea:, thanks for sharing picture

Hi Psuagro robincnn did some pulse measurements at this site, if you didnt saw it allready https://www.rollitup.org/t/top-bin-cob-comparison-2.897765/page-5

In 2 days i got a new driver ELG-150-54b, then i will do 2 new tests. One @50watt and the other at @100watt. Again the same cobs, clu058-1825/ 2700k 90cri vs cxb 3590 /3500kCD 80cri . Not really fair test between the cobs, but im still interested at the numbers. As soon i have datas i will share

you offer really nice price for the CLU058-1825 at ur shop, even with cob holder8). I noticed you are even the cheapest source for them:hump:

no i dont think so, i call tomorrow the company and ask them if it is possible through a software update

8-) Thanks guod

no thats not good idea, look what Greengenes707 wrote on page 1: BOBBY_G said: ↑ take your driver and hook it up to each cob individually Greengenes707said: Bad idea. Not within spec. 64-112v

i would take products from https://northerngrowlights.com/ in compare to area 51 leds, i read here in forum that some people had trouble with area 51 customer service. At https://northerngrowlights.com/ you can choose between the best cob manufactors, cree, citizen and bridelux. I would use...

I think in this led unit are these fans: http://noctua.at/en/nf-f12-pwm/specification They are high quality fans and the efficeny is top and silent they should be too. I think you cant find better ones with same performance

your self made stealth grow box looks amazing:shock::clap:, really nice and clean built. Like your lights too, the 1st build where each cob hang individual is pretty cool:idea:

Here some datas,

Jorge can you make me please a footprint chart like last time, but this time with 7points*7 points I was not able to edit ur old chart, i dont knwo how to work with excel Its pretty easy to place the cobs to the same postion, i just need too slide the one heatsink to left and the other too. its...

OK then i can today only compare 31watt against 31watt, from the wall. I will do footprints at 60cm*60cm, from 30cm distance, footprint will have 49 measurement points. Its clu058-1825/ 2700k 90cri vs cxb 3590 /3500k 80cri Both run passive on the same type of heatsink, i let both light heat...

yes with 2 others(same model), still same problem yeah://
