Hey guys I have a quick question. If I want to use passive cooling for 8 vero18 on a 42" length 5.888" profile, is that sufficient?

I'm very new to this so if you have any pointers please let me know.

Thanks Jorge. So realistically I should be doing 100 cobs for 100 sqft at 50% load of the cob to be on a 5k lumen range. Or 16 cobs in a 4x4 grow tent. What should I do about the driver. Should I go with the 240h or 320h? I'm thinking the 240h c1750b is the way to go for me? Since it will...

I will be making multiple panels. I have a 10x10 grow tent. I don't plan on using all of its space but i am planning to diy 8 panels total or more if needed. I want to sort out what i need for each panel for the cleanest install but yet easy to adjust the height as in i don't mind adjusting 8...

Airwalker, can you check this out and see if i'm on the right path. vero 29 4000k cob - max current: 4.2a (4200) Vf: 36.8v Matching to driver (example) hlg 320h c2100b has output of 156v 4 vero 29 cob : 36.8v * 4 =147.2v does that mean the cobs will fit on the driver because the driver...

How do i calculate the driver's amperage to match the cobs? I'm sorry for such a noob question but i would like to learn, "for a dummy".

thanks PB

Hey guys. Thanks supraspl for all of the information that you have blessed us with so far. I have my question posted in another thread. I believe the question is more suited for this thread. I am planning to run 4 vero 29 4000k cobs with a meanwell driver. I have my choices narrowed down to 2...

Thanks for pointing that out PB. How about the hlg 240h c1050b? I'll get stranded 18awg insulated for 300v. What about the solder, what do you recommend or like to use with a 60w soldering pen? I'm having a hard time understanding the numbers on led drivers. I know on meanwell 240h is the...

Hey guys i am changing my diy setup a little bit. I am now doing 4 vero29 4000k per heatsink. I will be using 42" 5.888" profile. I will be putting in a 140mm fan for safety measures. I am having a hard time picking a driver, which one of these two would you go with. hlg 240h c1400b or hlg 240h...

Thanks for the heads up Airwalker. I will add two fans to it. I feel like i don't have enough lighting for a 10x10 area. What do you think? Do you have any experience with these cobs? which one would you use?

HI guys, like the title states i'm new to led lighting and need help with what i need to buy. I am planning to build 4 panels. Each panel will consist of: 4 cobs (cxb3070 3000k or bridgelux vero v2 4000k) 1 5.886"x42" heatsink (heatsink usa) 1 meanwell hlg-185h-c1400b (jameco) 4 cob holders or...
