The rolson 61721 adjustable 6 led clip on light has been manufactured with 2 light heads each with 3 led bulbs for a bright illumination and are operated independently. Each of these light heads can pivot and rotate in any direction of 360 degrees. Both light heads have been mounted on a tall, strong and flexible neck with a length of 180mm, allowing for better manoeuvrability when aiming the light in a precise direction. The spring loaded clamp has a magnetic base allowing you to attach this light to different surfaces and with its maximum clamp jaw opening of 40mm it will clip on to most surface edges. This led clip on light requires 3aaa batteries which have been supplied. This adjustable clip on light can be used in many situations and would be ideal to keep in the workshop or garage to attach to the workbench. Its clamp allows your hands to be free when working on those small workpieces that require careful handling. The adjustable heads and neck gives you the ability to shine the lights at a precise angle to improve the visibility of the job at hand. This light would be great to help the hobbyist when constructing those models and aid in general diy repairs around the home.
