The LESOLEIL Q109 is an auto-darkening welding helmet with a 100 x 97 mm viewing window, four arc sensors and a solar panel backed by a replaceable CR2450 button cell. At £45.99 it lands at number 9 in this ranking — comfortably above the £27.99 model that carries the largest rating count in the set, and comfortably below the two helmets priced at £109.99 and £129.99.

The figure worth pausing on is the rating count. The listing says 4.5 stars from 262 ratings. The breakdown printed underneath it adds up to 100 — 72 five-star, 18 four-star, 6 three-star, 1 two-star and 3 one-star. That average is 4.55, so the star score fits 100 ratings rather than 262, and nothing in the listing accounts for the other 162. The shade range has a similar wrinkle: the bullet copy offers "DIN9-5/DIN9-13" where the item highlight says "DIN 5-9/DIN 9-13", so it is worth confirming which band you actually need. Everything on this page comes from the Amazon listing for the Q109, not from any testing we carried out.

## Questions people ask

**Does the LESOLEIL Q109 run on solar power alone?**

No. The listing says the Q109 uses solar cells together with a replaceable CR2450 button battery, so the battery can be swapped rather than the whole helmet replaced.

**What shade range does the LESOLEIL Q109 cover?**

The listing gives DIN 5-9 and DIN 9-13 in the dark state and DIN 4 in the light state, with stepless adjustment, and says it suits MIG, TIG, MMA, plasma welding and grinding.

**How many ratings does the LESOLEIL Q109 have?**

The listing quotes 4.5 out of 5 stars from 262 ratings, but the rating breakdown shown with it adds up to 100, not 262.

**How big is the viewing area of the LESOLEIL Q109?**

The listing states 100 x 97 mm, with four arc sensors and an optical clarity rating of 1/1/1/2.

**What is the LESOLEIL Q109 made of, and how much does it weigh?**

The spec table lists polypropylene as the material and 790 g as the item weight; the bullets describe it as lightweight but give no figure of their own.

**What comes in the box with the LESOLEIL Q109?**

The spec table says only "Comes as a Combo Set". The listing does not itemise the contents any further.
