Green is close to the eye's most sensitive wavelength and far more visible in bright conditions. Red draws less power and runs longer on a charge, which is enough in dim interiors.

What do 3x360 degrees gain me?

One horizontal and two vertical planes projected around the whole room. In suspended ceilings, partitions and tiling you get a reference on every wall without moving the instrument.

The laser will not level and shows a warning. Is it faulty?

No. Self-levelling usually covers ± 3-4 degrees; tilted beyond that the instrument cannot compensate and warns instead. Levelling the base roughly by hand is enough.

Can a line laser be used outdoors?

The beam is invisible in daylight. With a detector it works; for open ground and large areas a rotary laser is the better tool.

Construction lasers use a 5/8" thread as standard, and compact models often add a 1/4" photo tripod thread. Wall brackets and magnetic bases give an alternative mount on sections and track.

Line & Rotary Lasers

A line laser projects a line or a plane into the room and lets one person work along it. This page covers green versus red beams, what extra 360 degree planes change, the self-levelling range, and where a rotary laser becomes necessary. The catalogue holds 24 products from Milwaukee, Bosch and Makita.

Green beams, planes and accuracy

Green sits close to the wavelength the eye is most sensitive to, so at equal power it appears markedly brighter than red — which shows in bright interiors and at distance. Red draws less power, runs longer on a charge, and is enough in dim conditions.

The number of planes decides the job: a cross line laser gives one horizontal and one vertical line, which suffices for back boxes and sockets. 3x360 degree models throw one horizontal and two vertical planes right around the room, so suspended ceilings, partitions and tiling never lose the reference.

Accuracy is quoted in mm/m or mm at 10 m, typically ± 0.2-0.3 mm/m. The self-levelling range is usually ± 3-4 degrees: beyond it the instrument cannot level and warns instead — that is protection, not a fault.

Rotary lasers, detectors and mounting

A rotary laser sweeps a full plane with a spinning beam rather than projecting a fixed line, and its range far exceeds a line laser's. It is the tool for setting levels across a site, foundations, slabs and large volumes. Outdoors the beam is invisible, so it is used with a detector.

Mounting comes in two thread standards: 1/4" as on photo tripods and 5/8" as on construction tripods. Wall brackets, magnetic bases and wireless alignment bases fix the instrument to sections, track and walls, and models with fine height adjustment save time in tiling and ceiling work.

Green beam: visibility in bright conditions and at distance.
3x360°: uninterrupted reference right around the room.
Detector: finds the beam outdoors and at long range.
5/8" tripod thread: the construction standard; 1/4" for photo tripods.
