OK I have 2 of these LED inspection lamps
RIL3600HP | MAGflex Twist LED Inspection Lamp | Inspection Lighting

My car has very few light swirl marks.
IMO its almost impossible to see them in the daylight, but we have a halogen securuty light high up on the wall beside my driveway ... that picks them up nicely! But being fixed arent good for correction work ergo cant see the vertical sides etc.

I wondered are these extremely expensive dedicated swirl finders ( like the 3M Sunray) a lot better than these? And are the real one LED based?

Looking for something cheap, that could highlight these minor swirls in daylight. I.e. when I work on it.

To highlight a swirl is it better hold the lamp very close or as far away as possible ?
