The UNI-T LM550G-LD is a professional green line laser level in a 4V1H layout — four vertical lines plus one horizontal line and six reference points — for fast, all-round alignment on floors, walls and ceilings during tiling, partitions, wiring and fit-out work.
The bright 510–515 nm green beams self-level automatically within 3° (±0.5°) using gravity-pendulum magnetic damping, hold ±3 mm at 10 m, and reach 20 m on lines (25 m to a point). A rechargeable 4000 mAh Li-ion battery gives 5+ hours, and it ships with a tool box, safety goggles, target plate, strap and adapter. Genuine UNI-T product supplied by Digilog.pk with warranty and English manual.
