Notes: When dimensions or minor specs aren’t explicitly listed by FlexMax Laser, third‑party data is included only if it doesn’t contradict the official page (as above with the 1200 mm / Ø≈55 mm reference).  

The ECO70 delivers steady 70‑watt class output with a 75‑watt peak for short bursts, ideal for clean engraving and light‑to‑medium cutting. Pairing it with a 20K PSU helps ensure reliable ignition and consistent beam energy over time. FlexMax Laser specifies a 47.3‑inch tube length, a 2‑month manufacturer warranty, and an average service life of 2,000–4,000 hours under proper operation.  

For fitment and planning, many 70W‑class replacements share the “1200‑mm class” envelope; reputable third‑party listings for the Yongli 1200‑G (same power class) indicate ~1200 mm length and ~Ø55 mm diameter, which does not conflict with the ECO70 page and is useful when checking cabinet clearance, mounts, and mirror alignment ranges. Always confirm your machine’s brackets and path before installation.  

To maximize lifespan, run adequate water cooling, avoid extended jobs at 100% duty, and keep optics clean. Observing these basics keeps output stable and helps you stay within the stated 2,000–4,000‑hour expectancy.
