Verdict: The listings here offer a marking spray for bare metals and a replacement tube for a CO2 machine, but neither listing states glass as a marked material, and no UV laser machine is listed here at all. Pick the spray for metal marking and the tube only where its stated length and diameter fit; do not pick a UV machine from this comparison.
Machines on the list

Black Laser Marking Spray
A 16 Fl Oz marking spray for CO2 lasers, high-power diode lasers and fiber lasers, made for high-contrast black marks on bare metals, with water rinse cleanup.
Pros
- High-contrast, jet-black permanent markings on bare metals, per the listing
- Works with CO2 lasers, high-power diode lasers, and fiber lasers at 1064nm
- Plain water rinse for unreacted excess, with no harsh solvents required
- Light-green visual layer shows coating thickness and uniformity before marking
Cons
- Not a laser machine, so it cannot engrave on its own
- Glass is not named among the materials the listing states
- No laser power, work area or laser class is stated for this spray
- Durability claims rest on the maker wording, with no safety certification stated

Cloudray CO2 Laser Tube 50W 60W 70W Length 1000mm
A CR50 CO2 laser tube at 60W, max 70W, 1000mm long and 50mm in diameter, for replacing a 60W CO2 tube.
Pros
- 60W tube with a max of 70W
- TEM00 mode beam with high energy density and a stable spot, per the listing
- Glass metal sealing technology and nano gold catalyst coating, per the listing
- High voltage end and low voltage port arrive pre-connected, with a high voltage connector
Cons
- Not a complete machine, so it needs a compatible CO2 machine already in place
- Length and diameter should match the machine, and installation space should be slightly larger than the tube size
- No materials list, laser class or safety certification is stated
- Support is limited to issues within 4 months, after verification with serial number and photo or video proof

uv laser vs co2 laser for glass engraving: side by side
| Spec | HXOGYUB Marking Spray | Cloudray CO2 Tube 60W | Glass engraving note |
|---|---|---|---|
| HQ Score | 68 | 58 | Raw totals; the script fills the published score |
| Laser type | CO2, diode and fiber compatible spray | CO2 tube | Neither listing names a UV laser machine |
| Power | Not stated | 60W, max 70W | Power alone does not settle glass work |
| Size | 16 Fl Oz | 1000mm long, 50mm diameter | Size describes the can and the tube, not a work area |
| Materials stated | Stainless Steel, Aluminum, Brass, Copper, Titanium, Chrome | Not stated | Spray lists metals; neither listing lists glass as a marked material |
| Warranty or support | 2 Year Manufacturer | New tube within 4 months after verification | Terms differ in kind and length |
| Cleanup or fitting | Plain water rinse | Confirm diameter and length, and allow space slightly larger than the tube size | Fit and cleanup are the practical checks stated |
Specifications are manufacturer rated, as stated on each listing. Where a listing leaves a detail unclear, the table says so.
Laser power and cutting
The Cloudray example states laser power: a CR50 tube at 60W, with a max of 70W. The HXOGYUB example states no laser power, because it is a spray that works with a laser rather than a laser itself. Neither listing states a cut depth, a rated speed, or a glass cutting result, so this comparison does not crown a side on cutting power for glass.
Workspace
Neither listing states a work area for engraving. The spray listing states product dimensions of 2.76 Inches x 2.76 inches x 8.66 inches and a size of 16 Fl Oz, The tube listing states a length of 1000mm and a diameter of 50mm.
Materials
The spray listing names bare metals: Stainless Steel, Aluminum, Brass, Copper, Titanium and Chrome. It does not name glass among those materials. The tube listing names no materials, a replacement tube.
Software and ecosystem
Neither listing states software, an app, or a material library. The spray listing describes a visual coating layer and water rinse cleanup, while the tube listing describes pre-connected ends and a replacement support process.
Safety and enclosure
Neither listing states a laser class, FDA or CDRH compliance, an interlock, an e-stop, flame or tilt detection, or eyewear with a stated OD and wavelength range. The tube listing states high voltage connections, but no enclosure detail. Safety scores are therefore at the floor for both listings.
Ventilation
Neither listing states a filter, a fan, or a venting setup for laser smoke and fumes. The spray listing describes water rinse cleanup after marking, which is about the spray layer, not fume control.
Add-ons and growth
Neither listing describes an add-on system. The spray listing offers a light-green visual layer for checking coating thickness. The tube listing includes a high voltage connector with pre-connected ends.
Support and warranty
Support terms differ in kind. The spray listing states a warranty description of 2 Year Manufacturer. The tube listing states support within 4 months of receiving the tube, with a new tube sent after verification. The terms cover different kinds of items, so they should be read as stated, not as a head-to-head win.
Choose the HXOGYUB Marking Spray if
- Marking bare metals with a CO2 laser, a high-power diode laser or a fiber laser.
- Water rinse cleanup and a visible coating layer.
- A stated 2 Year Manufacturer warranty term.
Choose the Cloudray CO2 Tube 60W if
- A CO2 machine needs a replacement 60W tube.
- The stated length and diameter fit the machine.
- Pre-connected high voltage and low voltage ends matter for fitting.
Stay with the machine while it runs, keep a fire extinguisher nearby, ventilate, and never laser PVC or vinyl. Eyewear protects only where a listing states OD and a matching wavelength range, which neither listing here does.
Project Match
- Metal parts, tumblers, metal tools and personalized gifts: HXOGYUB Marking Spray.
- CO2 machine tube replacement where the stated length and diameter fit: Cloudray CO2 Tube 60W.
- Glass pieces: Not stated for either listing, since neither listing names glass as a marked material.
FAQ: lasers and CNC
Can either listing here engrave glass?
Neither listing states glass as a marked material. The spray listing names bare metals, and the tube listing names no materials. A UV laser machine is not among the listings here, so this comparison cannot judge UV glass work from these listings.
Is the HXOGYUB example a laser machine?
No. It is a 16 Fl Oz marking spray for CO2 lasers, high-power diode lasers and fiber lasers, used to create high-contrast black marks on bare metals, with plain water rinse for unreacted excess spray.
What power and size does the Cloudray tube state?
A CR50 tube at 60W, with a max of 70W, a length of 1000mm and a diameter of 50mm.
How is the spray cleaned up after marking?
The listing states that unreacted excess spray washes away with plain water, with no harsh solvents, alcohol or heavy scrubbing required.
Which listing states the longer support term?
The spray listing states a warranty description of 2 Year Manufacturer, while the tube listing states a new tube for issues within 4 months after verification.
