Secure, prop, light -- the compact Ledlenser iF4R is an easy-to-transport area light that always keeps your hands free when you need them. This is an extremely bright work spotlight -- 2,500 lumens that has five 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. Thanks to an integrated power bank feature, the iF4R not only supplies up to 15 hours of light (low power mode) but it will also power up additional electronic devices via USB.
