The STEELMAN 16102 11-Inch Flexible Gooseneck Bend-A-Light Mini Pro is a must have when you need to shed light into those small, tight spaces. Measuring 11-inches overall, this light has a 6-inch flexible gooseneck whose brass alloy construction lets it retain shape when bent or twisted to allow it to easily reach around corners and obstructions. The compact 5/32-inch diameter tip is small enough for the light to be used in a wide range of tasks including heavy machinery inspections, automotive engine troubleshooting, as a bore light for gun maintenance, or for computer and electronics repair / inspections. Two (2) AA alkaline batteries are included for your convenience. Filaments in the tiny, high intensity incandescent bulb can last for up to 4 hours of continuous runtime. When burned out or in the event of breakage, the bulb is designed to be easily replaced using the STEELMAN 12100 Bend-A-Light Pro Replacement Bulb.
