This compact 4.5" dome light is the cadillac of small, battery powered light fixtures. Using 12 super-bright LEDs in a high-impact ABS case, the lamp has several features not found on less-expensive puck light fixtures. Foremost, this lamp is BRIGHT and operates for at least 12 hours on a set of batteries. It can be mounted using the integrated magnets or the lens cover can be rotated and removed to permit permanent mounting using included hardware. Designed for automotive applications like RVs, trucks and utility vehicles, it works equally well at home in storage sheds or closets in need of extra illumination. Packaged in a poly bag and factory carton. (Installation hint: if mounting where you're not using the magnetic mount feature, install a small metal piece that the lamp can adhere to magnetically. This allows you to easily remove the lamp to replace batteries when needed).
