Forget about the light up ones, they are just a gimmick, designed to attract moths that think they will do a better job. Just try using them on a non conductive material, you will soon realise why. I actually gave one away a couple of days ago. As useful as a bowler hat with sleeves.

The ones from Arc Euro do a great job.
