Optrel crystal 2.0 Review
Verdict: The crystal 2.0 has the brightest light state we can verify (shade 2.0) and automatic shade selection, but Optrel itself rates the lens 1/1/1/2, not 1/1/1/1. This optrel crystal 2.0 review uses only specs the maker publishes; anything else is marked “not confirmed”.
It's in the $300–$600 band, with a spec score of 68/100.Compare it with the top picks in our best welding helmets ranking and the best auto-darkening helmets list.

Who the Optrel crystal 2.0 (silver) is for — and who should skip it
Buy it if: TIG and MIG welders who switch processes often and value a bright light state and automatic shading over window size.
Skip it if: Heavy stick or gouging work that needs darker than shade 12, or anyone who wants a big window.
Pros and cons
Pros
- Shade 2.0 light state — you can keep the hood down while fitting up
- Autopilot sets the dark shade between 4 and 12 automatically
- 460 g, the second-lightest auto-darkening helmet with a manufacturer weight
- Twilight mode lightens the lens gradually after the arc stops
Cons
- Optrel rates it 1/1/1/2 (angular dependence 2), despite 1/1/1/1 claims elsewhere
- 50 × 100 mm window (about 7.75 sq in) is small for the price
- Dark range stops at 12; Optrel's pages name EN 379 but not ANSI Z87.1
Our review
Optrel's own technical data settles two things that retail listings blur. The lens is EN 379 class 1/1/1/2 — the last digit (angular dependence) is a 2 — and the viewing area is 50 × 100 mm. Neither is bad, but neither is class-leading at this price.
What the crystal 2.0 does better than anything else here is the light state: shade 2.0, so you can see the joint clearly with the hood down. Autopilot then chooses the dark shade from 4 to 12, which suits welders who jump between TIG and MIG all day. Switching is 0.1 ms at room temperature.
At 460 g it is light, and buyers praise the visibility and colour rendering, with mixed comments on brightness. The limits are the 12 maximum shade and the certification list: Optrel's pages name EN 379 only, so if your site requires ANSI Z87.1 marking, check the helmet's label.
