TL;DR
The Ray7S 15W costs $369.99 for the Basic Set on Longer's store (October 2026). Inside the same Class 1 cabinet with Klipper firmware and a 305 × 310 mm bed, its 0.06 × 0.08 mm diode stays fine enough for photos while cutting 3 mm basswood in one pass by our estimate. It undercuts the cheapest enclosed xTool S1 by more than $600, with a smaller bed and no reviews yet.

What makes this machine stand out
Hardware and workflow features worth understanding before you buy : not just wattage on a label.
3 mm cuts in a closed cabinet
By our estimate, one-pass cuts in 3 mm basswood with the lid closed and the beam contained.
Far below the xTool S1
$369.99 in October 2026, more than $600 less than the cheapest enclosed xTool S1, with a smaller bed.
Our verdict
Ideal if you
The 15W Ray7S balances price and capability: a Class 1 cabinet, Klipper firmware and Wi-Fi, a fine spot for engraving and enough power for 3 mm hobby cuts, for well under $400.
Skip if you
Thicker plywood needs several passes, and the 305 × 310 mm bed is modest. The air pump is extra. Cabinet sealing and extraction are untested by independent reviewers so far.
Pros
- Cuts 3 mm basswood in one pass and about 5 mm with air assist by our estimate, inside a Class 1 cabinet
- Keeps a fine 0.06 × 0.08 mm spot according to Longer, close to the entry module for engraving
- $369.99 in October 2026, more than $600 below the cheapest enclosed xTool S1
Cons
- Air pump not included at this power: clean cuts need the optional pump
- 305 × 310 mm bed limits larger signs and panels
- No independent tests of the Ray7S cabinet or exhaust yet

Practical notes
Beginner notes
This profile is the 15W version of the Longer Ray7S. It suits home users who want a closed laser for engraving with occasional cuts in 3 mm wood: ornaments, coasters, small boxes. Compare the other Ray7S versions with the chips above if you plan to cut thicker plywood often. Add the optional air pump if you cut.
Pro tips
Fit the optional air pump before the first cuts; inside a closed cabinet it also helps clear smoke from the lens. Duct the exhaust out of a window for any cutting session. Keep the lid closed while the laser runs: the Class 1 rating only holds with it shut.

Common questions
How thick can the Ray7S 15W cut?
Longer does not publish per-version figures. By our estimate it cuts 3 mm basswood in one pass, about 5 mm with air assist, and 6 mm plywood in several passes.
Ray7S 15W or Ray7S 20W?
The 20W costs $529.99 against $369.99 for the 15W Basic Set (Longer store, October 2026). The $160 step buys faster cuts in 5–8 mm wood; for engraving with light cuts, the 15W is enough and leaves budget for the air pump.
Ray7S 15W or open Ray7 15W?
The open Ray7 15W costs $299.99, $70 less, with a larger 405 × 410 mm bed. The Ray7S adds the Class 1 cabinet and Klipper firmware: worth it if the laser shares a room with family or pets.
Alternatives to the Longer Ray7S 15W
Machines in the same space, picked from our database by type, price, and score.
Creality · Diode · $369 – $399
The Falcon A1C 10W is Creality's smallest enclosed laser: a 150 × 150 mm bed in a fully closed Class 1 box with a motorized lifting platform and auto-focus. It engraves cork, bamboo, slate, leather and plywood cleanly and cut 5 mm plywood in one pass in a hands-on test, barely. Small bed and plastic build are the trade-offs for the price.
xTool · Diode · $999 – $3,049
The 10W S1 is xTool's entry enclosed bundle: same Class-1 cabinet as 20W/40W, but the installed diode module limits cutting depth. You can upgrade later by swapping the laser head: verify you are buying the 10W SKU, not a bare machine without a module.
Sculpfun · Diode · $270
Sculpfun S10 10W (2022) is a mid-size open-frame engraver with a sturdier industrial frame than S9, ~385 mm work area, and detachable laser cover. Positioned between budget S9 and S30 families for makers who want better rigidity without Ultra pricing.
