Key features of the line laser
1. High-Visibility Laser Beams
The KLL-D600 Line Laser is available in both red and green beam models to meet different working needs. The red beam versions (KLL-D601R/602R/603R) operate at a 635nm wavelength with a powerful 100mW laser diode, ensuring sharp indoor visibility. The green beam models (KLL-D601G/602G/603G) feature a 520nm wavelength with a 30mW diode, providing up to four times the brightness of red beams—ideal for outdoor use or brightly lit spaces.
2. Fast and Accurate Self-Leveling
With a leveling range of ±3°, the KLL-D600 Line Laser automatically aligns itself in less than five seconds, allowing you to start working faster. Its precision accuracy of ±3mm over 10 meters ensures perfect alignment for tiling, ceiling installation, and framing tasks. This quick, hands-free leveling reduces setup time and increases job efficiency.

Powered by a 3.7V 4000mAh Li-ion 18650 battery, the KLL-D600 Line Laser delivers up to four hours of continuous use on a single charge. Its efficient power system guarantees steady laser brightness for consistent results throughout your workday. With an operating temperature range of -10°C to +50°C, it performs reliably in both cold and hot environments.
