SPECIFICATIONS Measurement Model: 16 Lines Wavelength: 515nm WEIDDW 08 leser level feature 1: professional laser level with remote control WEIDDW 08 leser level feature 2: laser level 4d 16 lines WEIDDW 08 leser level feature 3: Horizontal And Vertical Laser Level WEIDDW 08 leser level feature 4: 360°Self-leveling laser level shipping time: within 2 days Choice: yes semi_Choice: yes The laser level emits a bright, clear green laser beam that is visible up to 100 feet away, making it easy to get precise results. Its high visibility and accuracy are explicitly designed for home or office use—safety class II, <1mW power output. The laser level adopts a 4Dx360° 16-line layout, with 2x360° horizontal and 2x360° vertical lines, capable of covering every corner of a room and providing precise positioning. Users can choose to turn on or off any combination of horizontal or vertical lines. Self-Leveling Mode and manual mode Manual Mode:Lock the pendulum to switch to the manual mode, meet your alignment needs from different angles. Self-leveling Mode: unlock the pendulum,the laser level will self-level with 3° （the laser will keep flashing if the inclination exceeds 3） Multi Mode Switching:You can select self leveling or manual mode,Unlock the pendulum, the laser level will self-level within 5°(otherwise the laser will keep flashing). Lock the pendulum to switch to the manual mode, meet your alignment needs from different angles. The outdoor laser level is equipped with one 4400mAh rechargeable batteries, offering a longer usage time and lifespan. 2-power supply methoo: DC removable rechargeable battery rechargeable batteries in dc loading  Multiple Installation Methods The green laser level is equipped with a 1/4"-20 thread, suitable for standard tripods or laser mounting poles. The level kit also comes with a magnetic rotating base. The two strong magnets on the base can attach to metal tracks and steel materials, and the laser tool can be flexibly rotated to the desired angle. Plus mode The laser leveler uses a green laser with a wavelength of 515nm, which is four times brighter than the traditional red light and offers greater precision. The laser has four brightness levels, adjustable according to different environments. Its powerful beam is clear and precise, suitable for both indoor and outdoor use. Additionally, the laser level tool features a pulse mode; once activated, the laser will begin to flash.
