Bosch GLL50-40G Overview
The Bosch GLL50-40G is a green-beam 360° cross-line laser aimed at installers who want room-wide horizontal coverage without stepping up to a full three-plane laser. It projects a 360° horizontal plane and a vertical line independently or together.
360° Horizontal Coverage
The horizontal plane provides full-room leveling from one setup point, while the vertical line adds alignment capability for walls, cabinetry, tile and other installation tasks. Bosch specifies a working diameter of up to 100 ft and uses its bright green-beam system for improved visibility over standard red beams.
Simple AA-Battery Operation
The GLL50-40G runs on four AA batteries, which keeps power management straightforward on jobs where proprietary battery packs or charging are undesirable. A three-LED battery gauge helps monitor remaining power.
Protected for Jobsite Use
The housing uses a full rubber overmold around major impact areas and carries an IP64 rating for dust and water resistance. Bosch’s Smart Pendulum System self-levels up to 4° and locks the pendulum when the tool is switched off for transport.
Who Is the GLL50-40G Best For?
This is a strong choice for flooring, tile and interior installation work where a 360° horizontal reference is valuable but two additional vertical 360° planes are not necessary.
