Gozzle Actually, it doesn't, as it's spec (2W/180lm) is actually different to the product title and description (3W/240lm)

Gozzle I think you should have checked the datasheet, as this is only a 2W/180lm part!

Gozzle The product description has changed since I ordered the glasses and now states the very short focal length. However, the pictures on the box and website are still misleading, as they give the impression you can work on items at a normal working distance of 20-30cm
