Hi Robin, Thank you, for sharing the informations about the khatod optic. I was searching for a lens or refelctor with a wide beam angle for citizen clu058-1825. After checking khatod internet side, i saw they make the lens for CLU054. CLU54 have the same size like CLU058, so the lens(PL1825SR)...

:shock: what a jungle

Does it work like this for the HLG-320H-54b if i connect 5cobs, without to adjust the driver: 5,95A / 5 COBS = 1,19A per cob At 1,19A per cob it use around 51,1V(Tc=25C) 1,19A*51,1V(Tc=25C)=60,8W 60,8W * 5cobs= 304 W ? Maybe even more Watt when the driver has more Ampere then 5,95A.

Thanks bobby for your HELP. I think i will buy 2 HLG-320H-54b or 2 HLG-320H-48b. Which would be the better choose for 5*clu058-1825 for one driver? I would like to run one cob around 50watt. HLG-320H-54b = 5,95A / 5 COBS = 1,19A per cob HLG-320H-48b = 6.7A / 5COBS = 1,34A per cob could you...

Bobby do you use parallel drivers for your lights? have this parallel drivers any big disadvantages? Looks like the parallel drivers fit much better too the clu058-1825. Maybe i should buy one... or two

Thanks, the problem is i bought allready the drivers(2*HLG-320H-C1050b). I dont wanne buy some new driver if its not really necessary. It should be no problem to build my light without the cob holders or? The COB have 2 holes, i could screw it directly on the heatsink. Or alternative plan is, i...

Hi, guys could you please help me, if you have time and mood. I think my question fit good here i wanne build a new light with citizen clu058 1825chips. This cobs use around 50volt(+/-)@1050ma. I bought allready the cobs(10*clu058 1825) and and the driver(2*HLG-320H-C1050b), i bought even cob...

hi Jorge, i would like to know what do you think, can this heatsink handle CLU058-1825 @ 1050ma (passiv)?

Hi guys, i wanne build soon a new light, i will use 10* CLU058-1825. Now i wonder if the HLG-600H-54B would be a good driver for this cobs, 11,2A / 10 COBS = 1,12A for one COB. With 1,12A one cob use around 51V (=57watt one cob). http://www.mouser.com/ds/2/260/HLG-600H-SPEC-806212.pdf Looks...

Hello Sativied, i checked you":leaf:Sativied's Picture Journal:leaf:", pretty great work. Really nice photos too. I didnt checked the whole thread from you, but could i ask you what kind of light(hps/Led/... ) you use? and i think you allready tested a lot of different lights like hps or led or...

hi, if you talk about this chart which i post now, then i think the chart does specify indirectly which 90 cri version it is. I think it is Ra90 on B.B.L version, because the chart is for CLU058-1825C4 and CLU058-3618C4. for this both version dont exist a Ra90 below B.B.L. version.

hi, yeah you can veg and flower with the same cob light, 3500k would be a good choose

@Netherfly Hello, i wanted to say: thanks for sharing the link for the heatsink company from china. i bought some of the heatsinks and im happy with the quality and the price. good luck and much succes with your projects.
