So I finally ordered a couple COBs and wired one of them up. Honestly, I was a little shocked it actually lit up lol. Even the dimming works great. So about the multi-meter...I'm thinking I just didn't order a high enough quality one. I got this: https://www.amazon.com/gp/product/B00NWGZ4XC/ref=oh_aui_detailpage_o00_s03?ie=UTF8&psc=1 On the 2/20A setting the maximum reading reached is .012a, while my driver is 1.4a. I want to use the multi-meter to bring the current down to what's showcased in the COB's datasheet so I can determine the measurement distance used in that datasheet. What do you guys think? Get a better multi-meter? Or I'm overlooking something simple? Hopefully the latter. But hey, at-least the COB actually lit up! And damn this thing is bright.
