Shooting springers with flood lighted targets at night

I use a similar method. I use my ATN X-SIGHT 4K PRO night vision scope to shoot with IR flashlights and floodlights essentially doing the same thing. It lights up the pellet from behind and I've actually done some target practice with my rifles at night, recorded the video in slow motion, then analyzed the trajectory and flight dynamics of the pellets from the recorded video.
 
I bought a cordless LED light from Lowe's, put it on the highest setting and put it on a tool stand a few feet over my target. I didn't want to worry about plugging it in, yada yada, works excellently for me! I bought a backup Craftsman from Lowes as well. I can either double light the targets, or use the second one if the first one gives out.
