Home improvement tool for accurate levelling and alignment, aimed at making installations quicker and less frustrating. Confident results and simple controls help decorators and DIYers feel more in control. Is the Huepar Green Line Laser Level the right choice for everyday trade and home tasks?

⚡ At a Glance
  • Line Visibility: Bright green beams for clear indoor sight, easy to spot on walls and tiles
  • Best for: DIYers and tradespeople fitting doors, windows, cabinets and hanging pictures
  • Not ideal for: Long-range outdoor surveying in bright daylight where sunlight overpowers lasers

Self-levelling cross lines with simple manual override and USB-C charging. Compact, durable build tailored to domestic and light-trade jobs.


Long, reliable runs – thanks to rechargeable 3.7V 1400mAh Li-ion battery

Built-in 3.7V 1400mAh Li-ion battery supports up to six hours of continuous use and is charged via a Type-C port. Four battery indicators show remaining charge and the unit accepts charging from a laptop, power bank or car charger.

Long runtime removes constant battery swaps during a job and lets users finish medium-length tasks without interruption. Clear indicators make it easy to plan recharging between sessions.

Fast, accurate levelling – with a pendulum self-level and manual lock

Unlock the pendulum to enable self-levelling, which completes within about three seconds and flashes the beams when beyond the ±4° self-level range. Locking the pendulum switches to manual mode for angled or stepped layouts.

Quick set-up saves time when moving between marking points, and the manual lock lets installers create sloped reference lines when needed. Out-of-level flashing prevents hidden errors on awkward surfaces.

Clear cross lines and measured accuracy – with green diode technology and wide coverage

Advanced diode technology generates a green 110° horizontal line and a 110° vertical line with visibility up to 100ft and an accuracy of ±1/9 inch at 33ft (±3mm/10m).

Wide-angle, perpendicular lines make it simple to transfer references across a room for tiling, joinery and hanging wallpaper. Reliable accuracy keeps fittings square and reduces rework.
