Longer RAY5 Laser Engraver 10W Output Power - High-Speed DIY Cutter

Our review of the Longer RAY5 finds it a capable, high-power desktop laser for hobbyists and small shops who need faster cutting and a larger working area than entry-level units provide. The single biggest reason to buy is its combination of dual-beam high power and a 400 x 400mm work area that routinely handles thicker wood and acrylic than typical consumer engravers, while offering optional expansion for longer projects. Setup and daily use are approachable, and the unit balances performance with safety features that matter in a home workshop.

Key Features

• 10W dual-beam laser: Delivers cutting power that can slice through up to 0.8 in (20mm) wood and 1.2 in (30mm) acrylic for heavier tasks than most hobby lasers.
• High engraving speed: Max speed of 10,000 mm/min lets users finish cuts and raster jobs faster, reducing time on repetitive or larger projects.
• 400 x 400mm work area: A generous square bed that accommodates medium-size panels and allows comfortable placement of jigs and fixtures.
• Expandable work area: Optional extension kit increases reach to 850 x 400mm (33.46 in x 15.75 in), useful for longer pieces and batch production.
• Multiple transfer methods: Wi-Fi, USB, APP and TF card support plus offline APP control provide flexible workflow options when a computer is not desirable.
• Safety and stability: Protective cover and glasses plus an automatic stop routine for abnormal shaking reduce risk during operation.

Who It's For

The Longer RAY5 is aimed at makers, small woodworking shops, jewelry and craft makers, and hobbyists who want more cutting depth and speed than entry-level desktop lasers. Its combination of a stronger laser output, sensible safety features and a 3.5 in touchscreen makes it a practical step up for users who already understand basic laser safety and material settings.

It is less well suited to users who need micro-detail engraving at ultra-high resolution or those who cannot accommodate the physical footprint of a 400 x 400mm bed. Also, if absolute plug-and-play simplicity is required, some buyers report a short learning curve around assembly and screw sizes, so complete beginners should allow time to follow the instructions and online setup videos.

Pros & Cons

Pros

• Powerful 10W dual-beam output that cuts thicker wood and acrylic than many consumer lasers.
• Fast engraving speeds up to 10,000 mm/min for efficient production of larger jobs.
• Expandable bed option increases versatility for longer workpieces.
• Multiple data transfer options and offline APP control for flexible workflows.

Cons

• Assembly requires attention to detail; some users mention screw size as a minor annoyance.
• Not targeted at ultra-fine micro engraving where specialty optics or smaller spot sizes might be preferred.
