Taking advantage of COB technology—chip-on-board, which uses more diodes than a standard LED for bright, even light—the blue Stylus Pro COB Hands-Free Rechargeable Penlight from Streamlight is a pen-sized work light handy for many situations. The 40/160-lumen flood beam shines from a window on the side of the light. A magnet at the tailcap and a removable, rotatable clip provide multiple options for positioning so you can have your hands free for tasks. A push-button switch at the tailcap controls power on a constant-on basis. A fresh charge via the included micro-USB cable will power the Stylus Pro COB for 3 hours on high and 8.5 hours on low (there's also a flash setting for signaling, with a runtime of 7 hours.) This item comes in clamshell packaging.
