What is the difference between a detail light and a swirl finder light?

The terms are used interchangeably. A swirl finder is essentially a detail light with a specific purpose: revealing circular scratches (swirls) and holograms. All swirl finders are detail lights, but not all detail lights are equally effective as swirl-detection tools.

Which colour temperature reveals the most with detail lights?

For swirl detection, 6000-6500K works best: the light is bright white, barely bluish, and has just enough contrast to make fine circular scratches 'flash'. Polisher holograms are also clearly visible at 5500K.

Can I use a torch as a quick alternative?

A powerful LED torch with a high colour temperature gives a reasonable picture in a pinch. The beam is often too narrow for a large panel and the colour temperature is rarely optimised. For serious work, a proper detail light is the right choice.

At what distance from the paint do I hold a detail light?

For swirl detection: 10-20 cm at an angle of 15-30 degrees. For checking high spots in a coating: 5-10 cm straight on. Experiment with distance per paint colour; dark paints sometimes need slightly more distance to avoid overexposure.

Is a detail light useful for checking a coating after full cure?

Absolutely. After curing, the detail light shows whether the coating was applied evenly, whether there are areas with a thinner layer, and whether the gloss is consistent across the whole panel. That informs how you approach the next application.

Do I need to calibrate or maintain a detail light?

Calibration is not necessary; LED lights maintain their colour temperature for a long time. Keep the lens clean though; fingerprints and dust scatter the light and reduce contrast. Clean with a dry microfibre cloth.

A detail light is more specialised than a work light: it is designed to be used up close, at a sharp angle, to reveal swirls, holograms, and fine scratches that you would otherwise miss. The combination of high colour temperature, a compact beam, and high brightness makes the difference. Use it directly before and after polishing to assess whether you have achieved the desired result.

While polishing with a machine polisher, the detail light helps you monitor progress continuously. After applying a coating, use it to check whether the product has been distributed evenly and whether any high spots need to be buffed off.
