Sphere Series

Crystal 2.0 (Black)

With light transmission of 31% in bright condition (protection level 2!) welders have for the first time a practically unclouded and clear view of their working environment. This in combination with the almost perfect color spectrum of the CLT2.0 for the first time allows welders to see what is really going on in the weld pool, and with a clarity that equates to insights into a new dimension. This is why welders describe this as an enlightenment.

What is the size of the lens viewing area?

The viewing area is 50mm X 100mm. This equates to 10% larger than a standard 2″ X 4″ lens. If viewing area size is your most important feature you should check out our panoramaxx series of hoods.

Thanks. 50mm (1.9685″) x 100mm (3.93701). It’s actually smaller, but maybe the standard 2″ x 4″ don’t really have the full 2″ x 4″ viewing. I just got my Crystal 2.0 (first welding helmet ever) and need to dial in the adjustments… not sure if I’m going to opt for the halo accessory or the isofit headgear. The basic head gear the came with it wasn’t that comfortable… but I only adjusted the top of the head band… need to dial in the others and likely just need to get it “worn” in.

The 50mm x 100mm is the actual size of the viewing area. A 2″ x 4″ lens usually has a 1.25″ x 3.5″ viewing area but is measured by the outer dimensions, with frame and most likely solar cells that measurement is 2″ x 4″.

Thanks for the clarification. I probably don’t fully appreciate how clear the Crystal 2.0 is…. this is the only welding helmet I’ve every worn.
