Great thank you! I didn't think I could get pinned heat sinks for cheap enough to justify going with them over a bar. I will go with these.

Yea I have a frame with my main fixture and was going to branch off of that on the front and back to add more lighting. How much 5.886 do you think I'd need per COB? My bad missed the 4" part thanks!

I'm looking to put 8-9 Vero 13's on two approx. 40" heat sinks from heatsinkusa. I already have the COBs and want to use them as some supplemental lighting in my tent. They are being ran at 500mA about 15 watts a piece. I want them to be passively cooled. Which profile should I go with? I rather...

Okay thanks for the help. On Digikey it shows the 6th gen use 31volts the 7th gen says 34 volts. This is where I'm stuck. My understanding was even though it's 102 volts today it's not a big deal to go a tiny bit over. I just don't want to order them and find out I can't run three per driver. I...

Can't seem to get much help posting in existing threads so I guess I'll make a new one. I'm trying to decide on COBs for retrofitting an old LED fixture. It as 4 drivers 55-100v @500-550mA. I have two of these and already did one using the 6th gen Vero 13s 3 cobs per driver. Now for the second...

What's the difference between these two Vero 13s? Other than being square? I have 2 old 300w panels I'm switching to Vero 13s. I did one with 6th gens. I was going order more but came across these 7th gen and I'm wondering if I can use them. Seems they only have 3000k in stock. Also with the...

Ak49 Auto day 70. I'm thinking I still have another 3-4 weeks but figured I'd get some more experienced opinions thanks :)

About 300w 150 on the Vero 13 and Vero 29s. Grow area is 2x4.

I'm sure this has been asked but there's a lot of pages lol. Just want to confirm. I want to semi passively cool some COBs. I have 10 Vero 13s running at 500mA and I want to put a couple Vero 29s as well. What size heat sink would be recommend for this?

Thanks :)

Aluminum I had one 22 guage sheet it was a bit more flexible than I wanted so i got another so it's 2 22 guage sheets of aluminum. Plus the 2 original heat sinks and 3 fans. It is staying cooler than the original fixture.

Hi guys, first post I've lurked for a while and decided it was time to join. I wanted to share my fixture and had a couple questions. The COBs are Vero 13s 12 of them 3500k. Not sure what they are running at the drivers says 500-550 mA so I guess somewhere around there. 4 drivers 3 Cobs per...
