Product Q&A

Q:What does "16 lines" mean?

The LL-16B projects 2 x 360-degree horizontal lines and 2 x 360-degree vertical lines. Each 360-degree line appears as 4 line segments around the room (on four walls or floor/ceiling), so 2 horizontal + 2 vertical = 16 visible lines. This gives full-room reference coverage from a single setup.

Q:Is green laser better than red?

Yes. Green laser (520-532nm) is approximately 3-4 times more visible to the human eye than red laser, which means brighter, clearer lines and longer effective working range - especially valuable in brightly lit rooms and outdoor conditions.

Q:What if the surface is not level?

The self-leveling pendulum automatically corrects within 4 degrees and reaches level within seconds. If the tool is tilted beyond 4 degrees, the laser lines flash as an out of range warning so you can reposition it. For sloped applications like stair rails, press and hold the power button for 3 seconds to enter manual mode and lock any angle.

Q:How do I charge the battery?

The removable lithium-ion battery charges via a standard USB-C port using the included USB-A to USB-C cable. It can be charged from any USB charger, power bank, or laptop, and the blue digital display shows the charge percentage from 0 to 100 percent.

Q:How do I mount it?

The tool has a standard 1/4-inch thread and ships with a complete mounting ecosystem: wall bracket, magnetic bracket for metal surfaces, rotating base with fine adjustment, scissor-lift platform, keyhole mounting plate, and a professional tripod - covering floor, wall, ceiling, and metal-surface setups.
