Line laser level

Bosch Professional GLL 12V-100-33 CG Line Laser, Green Beam, 3x360°, IP65, in L-BOXX with Battery and Charger

Three green 360° lines cover floor, ceiling and walls at once — align a whole room without moving the tool.

The Bosch Professional GLL 12V-100-33 CG line laser projects three full 360° lines — one horizontal and two vertical — with ± 0.3 mm/m accuracy. Its green beam stays easy to see indoors across a 30 m radius, or up to 100 m with an LR 7 laser receiver. It ships in an L-BOXX case with a 12 V battery and charger.

Three 360° lines to align an entire room

The GLL 12V-100-33 CG casts one horizontal and two vertical lines, each running a full 360°. You can set out drywall, suspended ceilings, tiles, sockets and door frames from a single position, with no repositioning.

Remote line control via the Levelling Remote app

Lines can be switched on and selected from your phone through the Levelling Remote app, even from a ladder or the far side of the room. The Bosch GLL 12V-100-33 CG stays put while you keep working.

IP65 protection and rubberised housing for site use

Rubber-reinforced housing and laser windows plus an IP65 rating keep dust and water jets out. The GLL 12V-100-33 CG operates from -10 to 40 °C, so it works in unheated shells and outdoor site conditions too.

Dual power: 12 V battery or AA batteries

Power comes from a Bosch Professional 12V Li-Ion battery, with four 1.5 V LR6 (AA) cells as a backup option. In three-line mode runtime reaches 6 h on the Li-Ion pack, so a flat battery never stops the job.

Compatible with LR 7 receiver and 1/4" and 5/8" tripods

Paired with the LR 7 laser receiver, the Bosch GLL 12V-100-33 CG reaches a 100 m working radius, ideal on large or brightly lit sites. Both 1/4" and 5/8" threads let you mount it on compact and construction tripods alike.
