The versabrite 3 LED torch is favoured by the Police as it fits comfortably onto issue stab vests. The VB3 has 2 leds which produce 5.5 lumens (6000 candle power) from 2 CR2032 lithium batteries (supplied). The batteries last approximately 100 hours and are replaceable.The unit weighs just 30 grams and is 76mm long. Its made using Xylex polymer resin so is virtually unbreakable hence the lifetime guarantee. Its also water resistant. Our experience in the shop is that Police prefer the black unit while Paramedic units prefer yellow.
