Description

Achieve Precision Leveling with Superior Green Beam Visibility

Elevate your layout accuracy with the Bosch GLL50-20GL Green-Beam Self-Leveling Cross-Line Laser. Designed for optimal visibility, this tool projects vivid vertical and horizontal green beams that are up to 4X brighter than standard red lasers, making it ideal for bright ambient lighting conditions. With a working range of up to 65 feet and precision accuracy of ±5/16 inch at 30 feet, this laser is the ultimate companion for installing cabinetry, tiling, framing, and drop ceilings. Bosch’s exclusive VisiMax™ technology constantly monitors the laser's temperature and power consumption to deliver the perfect balance of line brightness and extended battery runtime.

Versatility and durability are at the core of the GLL50-20GL design. It offers dual-power flexibility, allowing you to run off the included rechargeable 3.7V Lithium-Ion battery—which operates even while charging—or switch to standard AA batteries (sold separately) to prevent downtime. The unit is built with a rugged, full rubber overmold housing that acts like a roll cage, protecting impact points and achieving an IP55 rating for dust and water resistance. Featuring a Smart Pendulum System, the tool self-levels on uneven surfaces, blinks to indicate out-of-level conditions, and locks securely when switched off to prevent internal damage during transport.

Key Features

  • High-Visibility Green Beam: Projects lines up to 4X brighter than standard red lasers for easier viewing.
  • Dual Power Options: Runs on the included rechargeable 3.7V Li-Ion battery or compatible AA batteries (sold separately).
  • VisiMax™ Technology: Optimizes power consumption to maximize line visibility and extend battery life.
