Every lens is the standard 2″ × 4.25″ size and drops into virtually any welding hood. The only exception is the Adjustable 1.0, which needs a slight modification to fit a TIGERHOOD, Outlaw Leather, or Pipeliners Cloud hood — instructions are included in the box.

Yes — the Single 2.0 is rated down to 20A and the Adjustable 2.0 runs as low as 5A with no flashing. The Adjustable 1.0 is not TIG rated (best for stick, MIG, and FCAW). The 2-Tone passive lenses work for all processes.

Most welders run between shade 9 and 13 depending on amperage. The adjustable lenses cover shade 5–13; single-shade and 2-tone lenses come in 9–12 (the Heir Single 2.0 is 8–11), so you can pick the exact shade you weld at.

Yes. Every lens meets ANSI Z87.1+, CE EN379, and CSA Z94.3, with permanent shade-16 UV/IR protection whether the lens is light or dark.

Solar power plus replaceable CR1025 batteries, with a low-battery indicator. The Single 2.0 is 100% solar — no batteries to change.

Every lens and hood is backed by a 1-year free-replacement warranty and a 90-day money-back guarantee. If it's not right, we'll make it right.
