You will find options for galvo setups, honeycomb beds, and control keys. Each pick is ranked by how well it matches common needs for CO2 laser users. This guide focuses on practical specs like tube length, lens focal length, and material compatibility. You can compare these items to find the exact part your machine requires without guessing.
Our top pick: DGHUNST 100W CO2 Laser Power Supply.
How alternatives compare to DGHUNST
Cloudray 40W CO2 Laser Tube
The Cloudray 40W CO2 Laser Tube replaces the DGHUNST power supply only if you need the tube itself rather than the driver. It measures 28.3 by 1.97 inches and outputs 40W, which is lower than the 80W-120W range the DGHUNST unit supports. You get a direct replacement for a 720mm tube, but you lose the high-power cutting capability of the 100W power supply. This pick suits users who need a straightforward swap for a standard 40W setup without complex wiring. It is not a power supply, so it does not control laser output. Choose this if your tube is broken and you need a new emitter, not a new driver.
XUNKUANER 210x210mm CO2 F-Theta Lens
The XUNKUANER 210x210mm CO2 F-Theta Lens serves a completely different function than the DGHUNST power supply. It is designed for galvo-based CO2 laser marking systems, not for standard engravers that use the DGHUNST unit. The lens weighs 6.4 ounces and covers a 210x210mm marking area. It provides precise flat-field marking for metal engraving tasks. You cannot use this lens to replace a power supply. It gives you high-precision marking capabilities but lacks the power delivery of the DGHUNST unit. Pick this if you are upgrading to a galvo system for detailed metal work. It is a premium optical component, not an electrical driver for CO2 tubes.
TEN-HIGH Aluminum Honeycomb Table 430x330mm
The TEN-HIGH Aluminum Honeycomb Table is a support structure, not a power component. It measures 430 by 330mm and offers a durable surface for smaller CO2 laser setups. Unlike the DGHUNST power supply, it does not emit or control laser energy. It manages smoke and supports materials during engraving. You gain a rust-proof, compact bed that fits smaller machines. You lose nothing electrical, but this item does not replace the power supply function. It is a budget-friendly choice for users needing a sturdy work surface. Choose this if your current bed is damaged or too small. It complements the DGHUNST unit but does not perform its electrical role.
TEN-HIGH 5" Focal Lens for CO2
The TEN-HIGH 5-inch Focal Lens is an optical part, not an electrical driver. It has a 127mm focal length and uses ZnSe optics for standard CO2 engravers. The lens weighs 3.53 ounces and measures 1.97 by 1.97 by 0.79 inches. It offers reliable optical performance but does not generate or control laser power like the DGHUNST supply. You get precise focus for cutting or engraving. You do not get a replacement for a faulty power unit. Pick this if your current lens is damaged or you need a specific focal length. It is a solid choice for maintaining beam quality, but it serves a different purpose than the 100W power supply.
TEN-HIGH CO2 Laser Machine USB Key
The TEN-HIGH CO2 Laser Machine USB Key is a hardware control dongle, not a power supply. It is a functional replacement key for CO2 systems, specifically for standard or upgrade machine versions. The model is ABCD. It does not provide electrical power to the laser tube. You gain access to machine control functions that may require this specific key. You lose the ability to operate if you need the original key and this is not compatible. Choose this if your machine requires a USB key for operation and you have lost or damaged the original. It is a small accessory that enables machine functionality, distinct from the high-voltage output of the DGHUNST unit.
OMTech 13 oz Metal Laser Marking Spray 3-Pack
The OMTech 13 oz Metal Laser Marking Spray is a consumable material, not a machine part. It comes in a 3-pack and is designed for marking bare metals with high-contrast black designs. The spray bottles measure 7.9 by 2.6 by 2.6 inches. It helps achieve durable marks on jewelry or tools when used with 25W+ CO2 lasers. It does not replace the DGHUNST power supply in any way. You gain better marking results on metals. You do not get any electrical or optical component. Pick this if you need to improve contrast on metal engraving projects. It is a practical aid for specific materials, separate from the power delivery system of your laser.
