Works sometimes - Competition Electronics Indoor Light

I usually shoot from a covered area. Prior to purchasing these infrared lighting screens, I built a light bar utilizing two 60W incandescent bulbs that works 100% of the time with my ProChrono but is cumbersome to setup and carry around the range. I bought these IR light screens to facilitate easier setup. I was totally disappointed that it failed to record less than 50% of the shots after shooting a couple hundred rounds over the chronograph on two outings. I am back to using my homemade light bar setup with 100% of shots recorded. I would not purchase again.
