I'm not sure how range on these things are calculated - perhaps maximum distance that an IR detector can detect the IR. I use this from a 2nd story deck ceiling to shine on my car in the parking lot, aiding the IR on my 15 meter camera IR. This unit adds to the picture, just 16 feet above the car, about like shining a dim flashlight with a dying battery. If you understand that the range is more like 20 feet, not 20 meters, and most effective under 10 feet, then this is a heck of a good bargain at 20 dollars.

Low price, work great, perfect for my board camera ordered here last time. Would come and get more!
