The Spectra Precision LT180G is a professional-grade green beam crossline laser engineered for interior contractors who need maximum line visibility without the complexity of a rotating laser. Projecting full 180-degree horizontal and vertical planes plus a downward plumb point, the LT180G accelerates layout on wall framing, electrical rough-in, tile work, and ceiling grid installation. Green beam technology makes lines up to four times more visible to the human eye than comparable red beam tools — a real advantage in well-lit commercial interiors where red lines wash out.
Jobsite Overview & Applications
Designed for the pace of a working jobsite, the LT180G self-levels within its operating range in seconds and locks out of level for manual slope or alignment tasks. The compact body fits standard 5/8-11 tripod threads, mounts to the included magnetic bracket, and runs on commonly available AA batteries. Whether you are squaring a room, plumbing a stud wall, or setting tile reference lines across an open floor, the LT180G delivers a consistent, bright reference without constant re-setup.

- Automatic self-leveling with out-of-level alert indicator
- Manual mode (grade mode) for sloped layout applications
- IP54-rated housing handles dust and incidental moisture on active jobsites
- Standard 5/8-11 thread base — compatible with most contractor tripods
- Magnetic pivoting bracket included for attachment to metal studs and track
- Pulse mode compatible with Spectra HR320 receiver for extended outdoor or bright-light range
Job Applications
Wall Framing & Stud Layout: Snap the LT180G onto a metal stud with the magnetic bracket and project a vertical line across the entire wall plane to align successive studs and verify plumb in real time — no chalk line re-snapping required.
Electrical & Mechanical Rough-In: Use the horizontal line to set a consistent elevation reference for outlet boxes, switch boxes, and panel knockouts across an entire room in a single setup. Crews move faster and inspections go cleaner.
Tile & Flooring Layout: Establish perpendicular reference lines from a single center point to lay out tile grids, luxury vinyl plank, or hardwood. The plumb point lets you transfer a floor reference point directly to the ceiling for feature walls or vertical tile runs.
Ceiling Grid Installation: Set the horizontal line at finished ceiling height and work both directions simultaneously. The 180° fan covers full room width, reducing the number of tool moves needed to complete a grid.

Frequently Asked Questions
- Can the LT180G project both lines at the same time?
- Yes. The LT180G can project the horizontal line, the vertical line, or both lines simultaneously depending on which mode you select. Running both lines at once is the standard configuration for square layout and tile work.
- Does the LT180G work with a laser detector?
- Yes. The LT180G includes a pulse mode that makes it compatible with the Spectra HR320 and LD-8 detectors. Using a detector extends the effective working range significantly and allows use in brighter ambient light conditions where the beam is hard to see unaided.
- What is the self-leveling range on the LT180G?
- The LT180G self-levels within ±4 degrees. If the tool is placed on a surface that exceeds that range, it will display an out-of-level warning rather than projecting a false reference line. You can also lock the pendulum manually for grade or slope applications.
- Is the LT180G suitable for outdoor use?
- The LT180G is primarily an interior tool. Its IP54 rating protects against dust and light rain, but green beam visibility outdoors in full sunlight is limited even on this model. For outdoor or long-range work, pairing it with a compatible receiver in pulse mode will extend its practical range considerably.
