The Coast SX300R C.O.B Work Light is capable of running on either a Coast ZITHION-X rechargeable battery or AAA alkaline batteries. With a multi-mode focusing optic for its main beam, the dust-resistant and weather proof handheld also features two ultra-bright and independently switched LEDs with Chip On Board (C.O.B) technology. The LEDs are revealed from inside the handle when it's extended to shine white, red, or red flashing. A magnet built into the tail cap makes for a handsfree lighting solution or a signaling mount during emergencies.
