LONGER Ray5 20W Review: Is This Laser Engraver and Cutter Worth It for a Home Workshop?

Is the LONGER Ray5 20W Laser Engraver and Cutter Worth It for a Home Workshop?

For a home workshop that wants a 400 × 365 mm diode laser with a 20W module and LightBurn or LaserGRBL support, the LONGER Ray5 20W is worth considering: the Amazon listing and LONGER's own Ray5 page agree on the working area, the 0.08 × 0.10 mm spot, the 0.01 mm precision figure, a 15 mm single-pass wood cut and a 35 mm acrylic maximum. Two points need settling before you buy, because the sources disagree: the maximum engraving speed (24,000 mm/min on the listing, 10,000 mm/min in the 20W column of LONGER's spec table) and the safety hardware in the box (the listing says a full protective enclosure; LONGER's Basic Set list names goggles and no enclosure).

Updated October 2026.

We did not test this product ourselves; this review is built from the manufacturer's published specifications and Amazon's product listing.

What the 20W module is rated to cut

Per the listing, the Ray5 20W "is equipped with a 20W high-power laser module" and is "capable of single-pass cutting 15mm (0.59") pine wood, 0.05mm (0.002") stainless steel, and 8mm (0.31") acrylic; with multiple passes, it can cut up to 25mm wood and 35mm acrylic". LONGER's spec table, in its 20W column, reads "Cutting Ability (Basswood) 15mm / one pass" and "Acrylic Max 35mm". The depth numbers line up; the wood species does not (pine on the listing, basswood on LONGER's page), and LONGER's table gives no stainless-steel cutting figure at all.

Acrylic deserves a second look. LONGER's materials FAQ says the diode laser "can cut wood, leather, MDF, paper, felt, and some dark opaque acrylic", which is narrower than the listing's unqualified "8mm (0.31") acrylic". If acrylic is part of your plan, LONGER's own wording, "some dark opaque acrylic", is the one to plan around, and LONGER closes that FAQ with "Actual results may vary depending on the material type, thickness, and processing settings." That caveat is the honest frame for every cut depth on this page; this walkthrough of a power and speed test grid is how you find the real numbers for your own stock.

Engraving: spot, precision and materials

Both sources state the same engraving geometry. The listing describes "an ultra-fine 0.08 × 0.1mm laser spot, achieving engraving precision of up to 0.01mm"; LONGER's table lists "Laser Spot Size 0.08×0.10mm" for the 20W, and a bullet on the same page promises "precision engraving up to 0.01 mm". LONGER's table also gives the wavelength, "450nm", which the listing does not mention.

The listing claims "an advanced 256-color palette" for color engraving on "stainless steel, metal, wood, leather, glass, acrylic, and cotton fabric". The 256-color figure appears only on the listing. LONGER's FAQ lists engraving on "wood, leather, bamboo, fabric, glass, ceramic, stone, stainless steel, and coated metals", claims compatibility with "200+ Materials", and adds that "with the optional Ruby 1064nm IR Laser Module, Ray5 can engrave more metals, including gold, silver, brass, iron, aluminum, and stainless steel." Gold, silver, brass, iron and aluminum, in other words, are listed under the optional IR module, not the diode.

Speed: the figure the two sources do not agree on

The listing says the Ray5 20W "supports a maximum engraving speed of up to 24,000mm/min". LONGER's spec table says something else: its 20W column reads "Max Engraving Speed 10,000mm/min", and the 24,000mm/min figure in that table sits in the 40W column. A bullet higher on the same LONGER page says the Ray5 offers "speeds of up to 24,000 mm per minute" without naming a module. So LONGER's page carries both numbers, and its own table assigns the lower one to the 20W.

This review does not pick a winner between them. Plan your throughput around the 10,000mm/min table figure and treat anything faster as a bonus.

Working area, expansion and modules

The working area is one of the cleanest agreements on the page: "400 × 365mm" on the listing, "400×365mm（15.75x14.37inch）" in LONGER's 20W column. LONGER's page adds that the base area expands "to 850 x 850mm(33.46*33.46inch)" and lists a "Large Format Expansion Kit" among its bundles, so the bigger bed is a purchase, not a feature of the Basic Set.

LONGER also describes the Ray5 as having "interchangeable laser modules (30W/20W/10W/5W/2W IR)", and the listing's variant is the 20W.

The listing makes one further claim LONGER's page does not: that the "ESP32 multi-core architecture" means "a single device can control multiple engraving machines simultaneously". That is the seller's claim, stated without detail, and LONGER's page as read does not mention the ESP32 chipset or multi-machine control.

Controls, connectivity and software

Per the listing, the Ray5 20W has "a 3.5-inch touchscreen for real-time engraving progress monitoring, quick parameter adjustments, and easy operation", and "supports USB, TF card, Wi-Fi, and app connectivity for both online and offline operation". LONGER's page as read does not mention the touchscreen, Wi-Fi or an app; what it does state is that the Basic Set includes "1 x Card Reader & TF Card", which is the offline route, and its connection FAQ describes a USB serial setup: check that "the CH340 driver is installed correctly", then "select the correct COM port in LightBurn and set the baud rate to 115200".

Software is a clean match. The listing names "LaserGRBL and LightBurn, as well as LONGER's own LaserBurn software"; LONGER's page says the Ray5 is "compatible with a variety of systems, including Windows and macOS systems, and software such as LaserGRBL, LightBurn and LaserBurn". Note that LONGER's page lists compatibility, not a bundled LightBurn license; neither source states that a license is included.

Safety hardware: read both lists before you buy

This is where the sources diverge most, so both lists are quoted in full.

Per the listing: "The laser head is equipped with a protective shield that filters over 95% of laser radiation, and the machine comes with a full protective enclosure and safety goggles to ensure safe operation. Built-in emergency stop, motion protection, overheating protection, and a hidden active cooling system help extend the laser's lifespan."

Per LONGER's page: "6 Layers of Safety", listed as "Blue Light Protection", "Limit Switch Protection", "Emergency Stop Button", "Motion Sensor Protection", "Data Loss Protection" and "Flame Sensor Protection". Its Basic Set contents include "1 x Protective Goggles". The page also notes that "the 5W and 10W versions do not include limit switches", a note that names only those two modules.

Three things follow. First, emergency stop, motion protection and goggles are on both lists. Second, flame detection appears only on LONGER's list, and overheating protection and active cooling only on the listing. Third, the enclosure: the listing says "a full protective enclosure", while LONGER's Basic Set list contains no enclosure and LONGER's page does not mention one. Before you rely on enclosed operation, confirm with the seller exactly what ships with this ASIN. Neither the listing nor LONGER's page states a laser safety class for the Ray5 20W, so no class is claimed here. This explainer on the enclosed-versus-open-frame safety tradeoff covers that distinction.

What is in the box

LONGER's "What's Included in the Basic Set" list: "1 x Ray5 Laser Engraver, 1 x Card Reader & TF Card, 1 x Wooden Brush, 1 x Protective Goggles, 1 x Allen Wrench, 1 x Cable Tie, 3 x Plywood, 1 x Laser Focus Column, 1 x User Manual". The listing's version is less specific: "The package includes all necessary tools and step-by-step installation guides", plus the goggles and enclosure discussed above.

Air assist is worth flagging. LONGER sells a "Cutting Kit (Air Assist & Honeycomb)" as a separate bundle, and the Basic Set list has no air pump; the listing does not mention air assist at all. On support, the listing promises "24/7 customer support and lifetime technical assistance"; LONGER's page states a "12-Month Warranty" and "24/7 Expert Support".

Key specs

Where it fits

• A home workshop cutting wood and MDF inside a 400 × 365 mm bed: both sources agree on the area, and LONGER rates the 20W at 15mm basswood in one pass.
• A LightBurn or LaserGRBL user who wants a machine both sources list as compatible, with LONGER's expansion kit and optional IR module as later purchases.

Where it might not fit

• Anyone relying on the enclosure. The listing claims one; LONGER's Basic Set list does not include one.
• Clear or light-colored acrylic work. LONGER's own wording is "some dark opaque acrylic".
• Throughput planning on the listing's speed. LONGER's 20W table figure is 10,000mm/min.
• Buyers who need air assist out of the box. LONGER sells it as a separate kit, and the listing does not mention it.

Verdict

The LONGER Ray5 20W is worth it for a home workshop if the Basic Set is what you expect to receive: a 400 × 365 mm diode with a 20W module, a card-reader-and-TF-card offline route, goggles, a focus column and software compatibility that both sources confirm. It is not worth buying on the strength of the listing's enclosure and 24,000mm/min claims alone, because LONGER's own page does not mention the first and its spec table assigns the second to the 40W module. Check the current price of the LONGER Ray5 20W on Amazon, and if the enclosure matters to you, ask the seller what it is before you order.
