The Spectra Precision LT360G is a professional-grade green beam line laser engineered for contractors who demand fast, accurate layout across full interior spaces. It projects three full 360-degree vertical planes and one 360-degree horizontal plane simultaneously, wrapping every wall, floor, and ceiling in sharp, continuous reference lines. Whether you're doing structural framing, MEP rough-in, tile layout, or finish carpentry, the LT360G delivers the coverage and brightness needed to stay productive without repositioning your instrument every few minutes.
Green Beam Performance Where It Counts
Green laser light is physiologically up to four times more visible to the human eye than red at equivalent power output. On a busy jobsite with ambient light flooding through windows or open doorways, that difference is immediately noticeable. The LT360G's green beam remains sharp and readable at working distances where a comparable red beam laser forces you to dim the room or use tinted glasses. Interior contractors doing layout, dropped ceiling grids, partition walls, or electrical and plumbing rough-in will find that less time chasing the line means more work completed per shift.

Job Applications
Partition Wall Framing: Set the LT360G in the center of the space and use all three vertical planes to simultaneously snap layout lines on the floor, transfer them to the ceiling, and verify plumb on intersecting walls — cutting layout time on multi-room floor plans significantly.
Dropped Ceiling Grid Installation: The 360° horizontal plane gives you a continuous level reference around the entire perimeter of the room without re-shooting. Hang your wall angle, then let the laser guide every main runner and cross tee to the same elevation without measuring off the wall repeatedly.
MEP Rough-In Layout: Electricians, plumbers, and mechanical contractors can use the vertical planes to establish consistent centerlines for conduit runs, pipe hangers, and duct drops — keeping trades aligned even when working in sequence across a floor plate.
Tile and Finish Layout: Use two intersecting vertical planes to establish a true 90° reference corner anywhere in the room, then build your tile grid or millwork layout off those lines for square, professional results on every install.

Frequently Asked Questions
- Can the LT360G be used outdoors?
- The LT360G is designed primarily for interior use. In outdoor or high-ambient-light environments, the visible working range will be reduced. Pairing the laser with a compatible Spectra green beam detector significantly extends usable range in bright conditions, making it viable for covered outdoor applications such as framing under a roof deck or working in a shaded area.
- What does the manual mode do on the LT360G?
- Manual mode disables the self-leveling pendulum and locks the laser in whatever position you've set it. This is useful for projecting intentionally off-level or sloped lines — for example, laying out a stair stringer angle, a sloped soffit, or a raked ceiling detail where a level line reference is not what you need.
- What batteries does the LT360G use and how long do they last?
- The LT360G runs on four standard AA batteries, which are widely available on any jobsite. Under normal operating conditions projecting all planes, expect approximately 20 hours of runtime. Using fewer planes simultaneously can extend battery life further.
- Is the LT360G compatible with standard laser tripods?
- Yes. The LT360G has a standard 5/8 in.-11 threaded mount on the bottom, which is the industry-standard thread used by virtually all contractor tripods, elevator tripods, and adjustable laser brackets. No adapter is required for typical setups.
