LONGER RAY5 Laser Engraver 20000mW Laser Cutter - High Power Precision

Our review of the LONGER RAY5 finds it best suited for makers, small workshop owners, and hobbyists who need a high-output, high-precision desktop engraver. The single biggest reason to buy is its 20000mW laser module that enables genuine single-pass cuts in thick pine and fine, photo-quality engraving using a 256-color palette and ultra-fine 0.08 by 0.1mm laser points. Setup is straightforward, and the machine pairs substantial cutting power with a compact 400 by 400mm working area for a versatile DIY tool.

Key Features

• 20000mW high output: Delivers single-pass cutting through up to 15mm pine and precise multi-pass cutting for thicker wood and acrylic, making it useful for woodworking and signage.
• High precision optics: Ultra-fine 0.08 by 0.1mm laser points and advertised 0.01mm engraving precision give very detailed results suitable for photo engravings and fine patterns.
• 256-color engraving palette: Built-in color mapping produces higher contrast and nuanced color reproduction for more creative, multi-tone engraving effects.
• Upgraded chipset and multi-core control: A 240MHz ESP32 chipset supports stable 7x24 operation and can coordinate multiple machines from one computer to improve throughput.
• 3.5in touchscreen and connectivity: Onboard touchscreen plus USB, WiFi, and app support allow offline operation and easy job monitoring without a constant PC connection.
• Safety and durability: Includes a laser head protective cover that filters most emissions, safety glasses, emergency shutdown, motion and heat protection, and active cooling for longer service life.

Who It's For

This machine is aimed at experienced hobbyists, makers running small production runs, and craft businesses that need a compact cutter able to handle wood, acrylic, leather, glass, and some metals. The combination of strong cutting power and fine engraving makes it particularly good for jewelry makers, signmakers, and anyone producing detailed wooden or acrylic goods.

Those who should look elsewhere include absolute beginners who want the simplest, lowest-power unit for purely occasional crafting, or users who need industrial-grade certifications and enclosure-rated safety for high-volume commercial manufacturing. Also, if your main work is thick metal cutting, a dedicated metal cutter would be a better choice.

Pros & Cons

Pros

• Exceptional cutting power for a desktop unit, enabling single-pass cuts in 15mm pine and fine engraving on multiple materials.
• High-resolution engraving with a 256-color palette and very small laser points produces highly detailed, photo-quality results.
• Flexible connectivity and a built-in 3.5in touchscreen make job setup and monitoring convenient without constant PC use.
• Comprehensive safety features and accessories, including a protective cover and safety glasses, reduce emission exposure during operation.

Cons

• Multiple-pass cutting is required for thicker materials, which increases job time compared with higher-power industrial lasers.
• Users expecting turnkey, beginner-only simplicity may face a short learning curve to exploit advanced settings and color engraving features.
