This light and battery pack can quickly and effectively be mounted to most riot shields. A wider beam angle provides panoramic lighting and immediate situation assessment so that you can see and respond faster. This is helpful in close quarters (hallways and doorways). Our shield lights are fully waterproof, fire-resistant, impact-resistant and can be used in all-weather situations. Taker R40 shield light delivers a blinding 650 lumens of light. Recharge the lithium-ion Ouick Swap™ power pack with Micro USB charger (included).
