The compact Ledlenser iF4R Music is Ledlenser's first-ever light paired with a bluetooth speaker. Now, not only can your light illuminate your workspace, you can connect to your smartphone and play to your favorite music, podcasts or radio station. The iF4R is an easy-to-transport area light that always keeps your hands free when you need them. This is an extremely bright work spot light -- 2,500 lumens that has 5 brightness levels so you can adjust to exactly right amount depending on the job. The iF4R has a very strong magnetic base to attach to metal surfaces and it is flexible so you can pivot and tilt the light to where you need it most. And charging is a breeze, thanks to its magnetic charge system.
