Product Description
The Plineasy LS-4JG is a compact 4D 16-line green laser level featuring four 360° laser planes for full-room leveling, alignment, squaring and layout work.
With horizontal and vertical 360-degree laser coverage, the LS-4JG provides reference lines across floors, walls and ceilings, making it suitable for professional construction, interior renovation, tiling, ceiling installation, cabinetry, partition installation and other precision layout applications.
The laser level combines ±3 mm/10 m accuracy, self-leveling operation, adjustable laser brightness, a built-in 3600mAh lithium battery and IP54 protection in a compact jobsite-ready design.
For tool brands, distributors and wholesalers, Plineasy also provides OEM and ODM laser level solutions for private-label projects.

The LS-4JG is a 4×360° laser level, meaning it projects four full-circle laser planes instead of only a conventional horizontal and vertical cross line.
The four-plane design provides laser references around the working area for floor, wall and ceiling layout.
This makes the LS-4JG particularly useful for projects requiring multiple reference points without repeatedly repositioning the laser level.
Typical applications include:
Floor and wall tiling
Suspended ceiling installation
Cabinet and kitchen installation
Partition wall construction
Door and window alignment
Electrical and lighting installation
Interior renovation
Flooring installation
Wall panel installation
Construction layout and alignment
The LS-4JG uses a high-visibility green laser beam designed to provide clear reference lines for indoor construction and renovation applications.
Its green laser wavelength is approximately 505–530 nm, with a working distance of up to approximately 30 meters under suitable conditions.
Compared with basic cross-line laser levels, the four 360° laser planes allow contractors to establish continuous reference lines around a room for faster positioning and alignment.
For larger jobsites or brighter environments, pulse-mode operation can be used with a compatible laser detector where applicable.
Precision is one of the most important factors when selecting a professional laser level.
The LS-4JG provides horizontal and vertical accuracy of approximately:
±3 mm at 10 meters
This makes it suitable for common professional leveling and alignment tasks including tiles, ceilings, cabinets, partitions and interior construction.
Accurate reference lines help installers reduce repeated manual measurements and maintain consistent alignment over larger working areas.
The LS-4JG features a self-leveling system designed to automatically establish level reference lines when the unit is positioned within its leveling range.
Self-leveling range: approximately 3° ±1°.
When the laser is within this range, the internal leveling mechanism automatically adjusts the laser planes.
For applications requiring an angled reference line, the pendulum can be locked and the laser level can be used in manual mode.
Manual mode is useful for applications such as:
Stair installation
Diagonal tile patterns
Sloped ceiling work
Handrail positioning
Decorative wall layouts
This combination of self-leveling and manual operation allows one laser tool to handle both standard level references and angled layout work.
The LS-4JG is powered by a built-in 3600mAh lithium battery.
Different laser brightness settings allow users to balance laser visibility and battery consumption according to the working environment.
Depending on the selected operating mode and laser brightness, runtime can reach approximately:
8 hours
12 hours
Up to 16 hours
Lower brightness can be used for indoor environments where maximum laser intensity is unnecessary, helping extend battery runtime during longer jobs.
Despite providing four 360° laser planes, the LS-4JG uses a compact housing designed for easy transport and positioning around the jobsite.
The laser can provide reference lines for three major working surfaces:
The lower horizontal laser plane helps establish continuous reference lines for flooring and tile installation.
It can be used for:
Ceramic tile installation
Stone flooring
Vinyl flooring
Hardwood flooring
Floor layout and alignment
The vertical laser planes help create straight and square reference lines across walls.
Common applications include:
Wall tiles
Cabinets
Shelving
Wall panels
Partitions
Doors and windows
The upper horizontal laser plane provides a convenient reference for overhead installation.
Typical applications include:
Suspended ceilings
Lighting fixtures
Ceiling panels
HVAC positioning
Electrical installation
Construction tools are frequently exposed to dust, debris and occasional water splashes.
The LS-4JG features an IP54-rated housing, providing protection against dust ingress and water splashes during normal jobsite use.
The housing is designed for professional construction and renovation environments while maintaining a compact form factor for easier storage and transportation.

A conventional cross-line laser normally projects one horizontal line and one vertical line onto a limited working area.
A 4×360° laser level projects multiple complete laser planes around the room, reducing the need to repeatedly move and reposition the laser.
The LS-4JG provides:
Two-dimensional and full-room alignment references
Floor-to-ceiling layout capability
Multiple horizontal and vertical reference lines
Faster squaring and alignment
Improved efficiency on larger installation projects
Greater flexibility for professional renovation and construction work
For installers working regularly with floors, walls and ceilings, a 4D laser level can significantly simplify layout work.
The LS-4JG is designed for professional users including:
Tile installers
Interior contractors
Ceiling installers
Cabinet installers
Electricians
Plumbers
Flooring contractors
Carpenters
Renovation companies
Construction contractors
It can be used for both general alignment tasks and projects requiring multiple simultaneous laser references.
