By [Laser Engravers Guide Editorial Team](https://laserengraversguide.com/about/) · Updated October 30, 2026 · [How we score](https://laserengraversguide.com/how-we-research/) Our score comes from manufacturer specs, professional reviews, and owner reports. It is not a hands-on lab test. ## The verdict On paper the Ray5 40W is the most cutting power in this guide for the money: a 40 W head, air assist and a 385 mm-square bed for around $650. It's also an open-frame Class 4 machine with manual focus and no camera, and its headline 20 mm one-pass cut hasn't been verified by an independent outlet we trust. Buy it for a garage or workshop where you can enclose and vent it. For a home office, the xTool S1 does similar cutting inside a Class 1 box for roughly three times the price. ### What we like - 40 W optical module with air assist included for about $650 - Maker claims 20 mm basswood in one pass, CO2-class thickness on paper - Runs offline from the 3.5-in touchscreen and TF card, or over Wi-Fi/USB with LightBurn - Flame and motion sensors, temperature protection and an emergency stop ### Watch out for - Open-frame Class 4 laser: goggles for everyone in the room, plus an enclosure or dedicated space - No camera or autofocus, so framing and focusing are manual - The thick one-pass cuts are a maker claim; we found no major-outlet test of this 40 W version - Diode limits still apply: no clear acrylic and no glass cutting ## Score breakdown Engraving & cutting 8.4 Ease of use 7 Safety & build 5.6 Value 8.4 40 W diode (output; 8-beam compressed module) · Open frame · Class 4 ## Ray5 40W specs | Brand | Longer | | --- | --- | | Laser type | Diode (Blue diode (~450 nm)) | | Output power | 40 W diode (output; 8-beam compressed module) | | Format | Open frame | | Work area | 385 × 385 mm (15.2 × 15.2 in) | | Max speed | 400 mm/s (maker rating) | | Laser class | Class 4 | | Cuts wood | Up to 20 mm (maker claim) | | Clear acrylic | No | | Metal | Marks bare metal | | Air assist | Included | | Camera | No | | Autofocus | No | | Rotary | Optional add-on | | Software | LaserBurn, LightBurn, LaserGRBL | | Connectivity | Wi-Fi, USB, TF card, app; 3.5-in touchscreen | | Weight | 12.6 lb | | Warranty | Not stated on the listing — confirm before buying | | Price tier | $$ Mid-range ($500–$1,500).

Confirm the module wattage before ordering. - Longer's own store sold Basic/Pro/Pro Max bundles from $679.99 on Oct 29, 2026; Amazon showed $647.99 against a $799.99 list price. - Longer lists thin stainless engraving and cutting; a blue diode's mark on bare stainless is slow and low-contrast next to IR or fiber. - No hands-on review of the 40 W model from a major outlet found; the score is cautious. ### Bundles and power options Each option is a separate Amazon listing. Prices are typical street prices, not live. | Option | What's different | Price | | --- | --- | --- | | Ray5 20W | Half the power, 400 × 365 mm bed | [Check price](https://www.amazon.com/dp/B0G138YL1H?tag=laserengraversguide.com-20) | | Ray5 40W | Our pick: 40 W module with air assist | [Check price](https://www.amazon.com/dp/B0FNRFK21L?tag=laserengraversguide.com-20) | Specs are compiled from manufacturer listings and independent reviews and may change between production runs. Laser makers re-bundle often, so confirm what's in the box on the Amazon page before buying. The Longer Ray5 40W is an open-frame diode laser with a 40 W optical module, air assist in the box and a 385 mm-square bed for about $648 (check today’s price). On paper it offers more cutting power per dollar than anything else in our guide, with a claimed 20 mm basswood cut in one pass. It’s also an open Class 4 machine with manual focus and no camera, and that headline cut hasn’t been checked by an independent outlet we trust. To see whether an open-frame cutter fits how you work, try the [laser matcher](https://laserengraversguide.com/tools/laser-matcher/). ## Who the Ray5 40W is for (and who should skip it) It’s for makers who want to cut thick wood, such as box joints, layered signs and furniture parts, and who have a garage or workshop where an open-frame laser can be enclosed, vented and supervised. If you’ve outgrown a 10 W diode and can’t justify a CO2 or an enclosed 40 W, this is the budget route to thick cuts. Skip it if the laser has to share a home office or a room with kids. For similar cutting power inside a Class 1 box, the [xTool S1 40W](https://laserengraversguide.com/laser-engravers/xtool-s1-40w/) costs roughly three times as much but needs no goggles with the lid shut. If you don’t need 40 W, the [Atomstack A20 Pro V2](https://laserengraversguide.com/laser-engravers/atomstack-a20-pro-v2/) is a cheaper open frame, and if clear acrylic matters, no diode will do; look at a CO2 such as the [OMTech K40+](https://laserengraversguide.com/laser-engravers/omtech-k40-plus-45w/). ## Key capabilities The 40 W module combines eight beams into a compressed spot, which Longer specs at 0.10 × 0.15 mm. Longer claims 20 mm basswood and 0.15 mm stainless steel in a single pass, at up to 400 mm/s (24,000 mm/min). Those are maker figures. We found no hands-on review of the 40 W model from a major outlet, which is why our score is cautious despite the specs. Our [best laser cutter for wood](https://laserengraversguide.com/posts/best-laser-cutter-for-wood/) guide puts it in context against enclosed and CO2 cutters. The usual diode limits still apply. It can’t cut clear acrylic or glass. On bare stainless the blue beam leaves a slow, low-contrast mark, so for real metal work look at fiber. Dark opaque acrylic, wood, leather and coated metal are its territory. Check specific materials in the [material checker](https://laserengraversguide.com/tools/material-checker/?material=hardwood). ## Day-to-day use The Ray5 is more self-contained than most open frames. The 3.5-in touchscreen and TF card let you run saved jobs without a computer, and you can also connect over Wi-Fi, USB or Longer’s app. LightBurn and LaserGRBL are supported alongside Longer’s own LaserBurn software, so you won’t be locked into one program. You’ll focus manually and frame jobs with the laser head, since there’s no camera or autofocus. Safety features include flame and motion sensors, temperature protection and an emergency stop. At 5.73 kg the frame is easy to move between a storage shelf and the bench. ## What you’ll need beyond the box - **Eye protection for everyone in the room.** [Blue-diode glasses rated for 445–455 nm](https://www.amazon.com/dp/B08R4PMCHR?tag=laserengraversguide.com-20), one pair per person. - **Enclosure and ventilation.** A 40 W diode cutting thick wood makes a lot of smoke. A [fire-resistant enclosure with an exhaust fan](https://www.amazon.com/dp/B0C3GLYC3Y?tag=laserengraversguide.com-20) (about $47) helps contain it; measure first, since the Ray5 40W is close to its 700 × 720 mm limit. Then duct it outside with [4-inch aluminum ducting](https://www.amazon.com/dp/B01EUURUVM?tag=laserengraversguide.com-20). The [ventilation guide](https://laserengraversguide.com/posts/laser-engraver-ventilation-guide/) covers fans and window kits. - **Air assist.** Included, a real saving over machines that sell it separately. - **Rotary.** Optional. A [roller rotary](https://www.amazon.com/dp/B08CBV2B6N?tag=laserengraversguide.com-20) is a common choice for tumblers on GRBL diodes; confirm the connector. - **Fire safety.** Thick cuts mean long jobs. Keep an [ABC extinguisher](https://www.amazon.com/dp/B084P5PPNC?tag=laserengraversguide.com-20) and a [fire blanket](https://www.amazon.com/dp/B08TYT543Y?tag=laserengraversguide.com-20) nearby and never leave it running. See our [safety guide](https://laserengraversguide.com/posts/laser-engraver-safety-guide/). ## Reliability and warranty There’s no major independent review of this version, and our model data doesn’t list a warranty term, so confirm coverage with the seller. Longer’s own store sold Basic, Pro and Pro Max bundles from $679.99 on October 29, 2026, while Amazon showed $647.99 against a $799.99 list price. The cheaper Ray5 20W (about $370) uses the same platform with a 400 × 365 mm bed. ## Bottom line The Ray5 40W is the budget open-frame cutter to buy if thickness per dollar is what you’re after: 40 W, air assist and offline control for about $648. Its limits are an open Class 4 beam, manual focus, no camera and a headline cut nobody independent has confirmed. Put it in a workshop, enclose and vent it, and it makes sense.

That's Longer's claim for basswood. We found no major-outlet test of the 40 W version, so treat 20 mm as a best-case maker figure. Dense hardwoods and cheap plywood with glue layers will cut more slowly or need extra passes. ### Does the Ray5 40W need a computer? No. It has a 3.5-in touchscreen and a TF card slot, so it can run saved jobs offline. It also connects over Wi-Fi, USB or Longer's app, and works with LightBurn and LaserGRBL. ### Is the Ray5 40W safe indoors? It's an open-frame Class 4 laser. Everyone in the room needs glasses rated for the blue diode wavelength, and it should be enclosed or kept in a dedicated, ventilated space. It has flame and motion sensors, temperature protection and an emergency stop, but those don't contain the beam or the smoke. ### How do I make sure I'm ordering the 40 W version on Amazon? The Amazon listing groups Ray5 configurations under work-area labels. The 40 W is the '385x385mm' option; the 20 W has a 400 × 365 mm bed. Confirm the module wattage on the page before you check out. ## Sources - [amazon.com](https://www.amazon.com/dp/B0FNRFK21L?tag=laserengraversguide.com-20) - [longer.net](https://www.longer.net/products/longer-ray5-40w-laser-engraver) Not sold yet? ## Alternatives to the Ray5 40W ![Atomstack A20 Pro V2](https://laserengraversguide.com/_astro/atomstack-a20-pro-v2.BTB1tY3b_FAafY.webp) ### [Atomstack A20 Pro V2](https://laserengraversguide.com/laser-engravers/atomstack-a20-pro-v2/) 7.2 - 20 W diode - Open frame - 400 × 365 mm - Bare metal Hobbyists comfortable with an open-frame machine who want 20 W of cutting power and a big bed for under $400. $$$$ Budget Price tier: Budget base bundle on Amazon [Check price on Amazon](https://www.amazon.com/dp/B0DHG5LNKL?tag=laserengraversguide.com-20)[Read the full review](https://laserengraversguide.com/laser-engravers/atomstack-a20-pro-v2/) ![Creality Falcon A1 10W](https://laserengraversguide.com/_astro/creality-falcon-a1-10w.xF0nr-n8_ZAOBpI.webp) ### [Creality Falcon A1 10W](https://laserengraversguide.com/laser-engravers/creality-falcon-a1-10w/) 7.9 - 10 W diode - Enclosed - 381 × 305 mm Beginners who want a goggles-free enclosed laser with a big bed and a placement camera for under $600. $$$$ Mid-range Price tier: Mid-range base bundle on Amazon [Check price on Amazon](https://www.amazon.com/dp/B0DRVQNYQ1?tag=laserengraversguide.com-20)[Read the full review](https://laserengraversguide.com/laser-engravers/creality-falcon-a1-10w/) ![xTool M2 10W Color Craft Laser](https://laserengraversguide.com/_astro/xtool-m2-10w.qZctskiw_T0oHC.webp) ### [xTool M2 10W Color Craft Laser](https://laserengraversguide.com/laser-engravers/xtool-m2-10w/) 8.5 - 10 W diode - Enclosed - 426 × 320 mm - Bare metal First-time buyers who want a genuinely home-safe, camera-guided laser for gifts, stickers and crafts, with room to grow into more power or color printing. $$$$ Budget Price tier: Budget base bundle on Amazon [Check price on Amazon](https://www.amazon.com/dp/B0GSVLTBH4?tag=laserengraversguide.com-20)[Read the full review](https://laserengraversguide.com/laser-engravers/xtool-m2-10w/) [Compare all 16 lasers →](https://laserengraversguide.com/laser-engravers/) ## Helpful guides [Top picks ### The 7 Best Laser Engravers of 2026: Ranked for Home, Craft and Small Business The best laser engravers of 2026, ranked: xTool P2S, xTool M2, Creality Falcon A1 Pro, xTool F2 and more, with honest wattage, laser class and price notes.
