Hi, I wondered if anyone has experience using this lamp: Multi Magnification Led Bench Lamp 5 Type from Cooksons. How good is it and is it good when doing piercing work or will I be hitting the light and magnifying lens with the saw frame? I need to get a new bench light anyway plus I also do use Optivisor as well as wearing glasses due to being long-sighted, so I wonder if this is a good solution or will it overcomplicate things. Thanks! Nat
