Multi-Line Laser Levels
Premium 3D, multi-line and 360° line laser levels for level, alignment and square. Class 3 green beams that stand out where Class 2 lasers struggle. Built to be calibrated, repaired and used as everyday trade tools — not throwaways.
Multi-Line & 3D Line Lasers
From plumb-rotating 4-line cross lasers through to 3D 360° lasers and the electronic-levelling XLG44 — the most fully-featured line laser level we sell. Every premium model is Class 3, properly calibratable, and backed by Australian repair and support.
Pick by lines, by mounting style, or by the work you do. Cross lasers for tiling and small set-out. 3D 360° for floor-to-ceiling fit-out and squaring. XLG44 family for daily trade use where accuracy and durability matter.
Three jobs, one laser
A multi-line laser projects a set of horizontal and vertical lines from a single base, all referenced to the same self-levelled point. That gives you three core capabilities anywhere on site.
Level
The horizontal line gives you a perfectly level reference around the room — for tiles, dado rails, suspended ceilings, kitchen joinery, switches and outlets, picture rails, bench heights and anything else that needs to sit level.
Alignment
Vertical lines run perfectly plumb from floor to ceiling and let you align studs, partitions, fixtures, doorways, columns or anything else that has to be plumb. Plumb-dot models add a dot directly below for transferring points up from the floor.
Square
Multi-line and 3D lasers project two vertical lines at exactly 90° to each other, giving you instant square for set-out, room layouts, tiled areas, framing and shop fit-out — no string lines or chalk needed.
Why our line lasers are brighter
Brightness on a line laser comes down to two things — the laser class (power output) and the quality of the diodes producing the lines. RedBack premium line lasers run ahead on both.
Class 3R green & red lasers
<5mW
Power output across the premium range. Class 3R is the brightest laser class you can legally sell or use for construction in Australia (and most of the world).
- Class 3R green & red — up to 5× brighter than the Class 2 lasers most other brands sell
- Premium German OSRAM diodes on the green range — lighter, sharper wavelength most users find easier to see
- The XLG44 is powered by 9 laser diodes — one per line plus the plumb dot — vs the standard 3 diodes other multi-line lasers use
- Visible at greater distances indoors, holds visibility in well-lit spaces where Class 2 lasers wash out
Class 2 lasers
<1mW
Around 95% of line lasers on the market are Class 2 — five times less power output than Class 3R. Most competitor brands rarely advertise the laser class for that reason.
- Standard 3-diode line projection — fewer, dimmer lines
- Generic diodes — more variation in brightness, sharpness and longevity
- Visible only at shorter distances or in lower-light conditions
- Not ideal for well-lit interiors, larger rooms or daily trade use

Take a line laser outdoors
Line lasers project a visible beam — but in 99% of outdoor conditions the sun overpowers it. The fix is a line laser receiver. Pair any of our premium line lasers with a receiver and you can detect the lines anywhere outdoors, opening up most of the capability of an outdoor rotating laser plus easy vertical alignment, square and set-out.
Red beam line lasers paired with a receiver run to ~150m radius. Green beam line lasers paired with a receiver run to ~40m radius. Both work from the same receivers in the range.
Line laser receivers
Calibratable, repairable, not throwaway
If you’re shopping for a line laser in Australia, do the calibration check before you buy. A surprising number of “premium” lasers — including those sold at premium prices by some of the biggest tool-store chains — can’t physically be calibrated when they drift, and don’t have spare parts available either.
Buyer beware — big-name doesn’t always mean backed
Many big-brand line lasers cost more than half the original purchase price for a simple calibration. Others can’t be calibrated at all. Many of those brands actually direct people to us to get their lasers serviced — and we end up telling people we can’t help, because the lasers physically don’t have the calibration access they need.
Every RedBack premium line laser is designed to be calibrated and repaired in-house. Send it in, we’ll check it, adjust it, fix it where needed. If you want a recommendation on which brands to avoid, we’re happy to talk you through it.
Tripods, monopoles & brackets
A line laser is only as good as where you can put it. Indoor monopoles for floor-to-ceiling height adjustment, wall brackets for permanent mounts, full tripod and staff bundles for outdoor use — the right accessory turns a laser into a complete kit.
If you don’t need premium-grade build, our budget line laser range covers indoor cross-line, plumb-dot and entry-level multi-line work — same Australian support, calibration and repair backing.
Line Laser Questions
Why are RedBack line lasers brighter than other brands?
Is laser class important for line lasers?
Can line lasers be used outdoors?
Are green line lasers brighter than red line lasers?
Red line lasers are generally cheaper than the green equivalents, and have a wider working range when used with a receiver for outdoor work (~150m vs ~40m for green).
