Laps that fall and get damaged on the side ...

Hi,

I made a stupid mistake and three laps fell off their rack : my sintered (600, bronze, on picture) and two zinc ones ... They all have a dent on the side and the metal has locally lifted/bumped.

As a result, the metal has locally hardened (in addition to the dent and bump) and I don't see how to fix it ... I suppose it's ruined and all I can do is avoid the outside of these laps ... Too bad, I've noticed that the outside often cut faster ! I feel incredibly stupid, I've damaged hundreds of dollars' worth of laps ...

GU10 230V LED lamp less than 10cm from my head some hours every day : bad idea ?(!)

Hi !

For precision work, I need a light source very close to my face (3 to 10 cm) for several hours a day.

Between electromagnetic radiation and blue light, I'm thinking a GU10 230V LED bulb isn't ideal (or even dangerous)

Would a 20W, 12V halogen GU10 bulb be better ? (with a built-in UV filter)

What other solutions are there ?

Thank you ! :)
