My lathe is lit by 3 12v halogen lamps with solid state transformers and is just about adequate. Last night one blew, and to finish the job I put on my 6 LED headlamp. What a difference ! Can't think why I never thought of it before, good light, good colour, cost £3. Also have used my rechargable LED inspection lamp, this also gives good contrast, seems the LEDs are a bit different to some others. BTW I have little hair to worry about.
