Even the brightest bulbs will eventually burn out and need to be replaced. The STEELMAN 12120 is a replacement bulb for the 16-Inch Micro Pro Bend-A-Light part number 10250A. Using the same type of high intensity bulb as the stock Bend-A-Light it provides the same level of bright, long lasting light for far longer than a traditional bulb could manage. The grain of wheat sized bulb comes built-into in a plated brass and plastic fitting that is threaded so that installation is quick and painless, getting you back to work fast. Retaining the same 3/32-inch diameter as the original bulbs it has an approximate continuous burn time of 50-hours.
