Lighting So it begins, the DIY COB addiction

I made 20 ft of aluminum angle today for the frame.

Correct. M3x8 works best for cob holders. M3x6 are a little short. Hardware stores are the best for these, amazon has limited stock and they are pretty expensive coming from USA. Coming from China takes 4 weeks. Just screws but you need them. I checked home cheapo and they don't sell them.

Thanks for verifying that I wasn't quite sure. Yeah I bet the local true value has them, I'll go check tomorrow.

My favorite store. Yes they will. Careful screwing them into the anodized sink. Might want to use one as a tap before sticking a cob under the drill. I have thrown away plenty of cobs with a philips bit impression in them lol.

They had 54 m3 x 8mm screws, I got them all. :smoking: They also had wago's for a decent price so I picked up more for the next project.

@BigSm0 What's your opinion on the best citizen color temps and cri's from seed to harvest to use?

Hope you had a good Christmas, did Santa bring you anything this year?

Subbed up!!!

That's a tough one. 3500k seems to be the favorite for flower and veg.

I would go with either 3500k 90cri or or 4000k 80cri. No matter which one you choose it will give or take from a certain area since there is only so much useable light given off.

Very tough question

Merry Christmas to you too bro.

Thanks for the graphs, that helps a bit. I got the 80 cri 3000k from cobkits cause that's all they had in stock. I guess I'll use those for this project and I'll try to get what you recommend for my next. I'm ordering more cobs next week, these HID's are ready to be unplugged.

Another ?
Do you know if the color temp and cri changes any relative to how hard the cobs are driven?

The closest match to the mc cree curve are the 3500 80cri ones. So if you don't plan to run supplemental ones to your main cobs that would be best.
