The cheapest portable videolight

Just showing you how I made my very first video light based on 12v led COB and powered by 4 18650 li-ion batteries. It lasts about 1 hour on full power. Then lux level starting to decreasing. Cons is LED itself, it’s a bit greenish and CRI is pretty poor, but still usable for for subjects. Hope you could overcome my audio lavalier microphones augmentations. You can compare cheap lavalier zoom h4n and incamera sound at the end of the clip. That’s the cyberpunk that we deserved here in Russia. Need more - S
