Product type comparison

Torch vs floodlight vs bulb vs strip vs spotlight

The product shape matters as much as wavelength. A torch and floodlight can share a wavelength but solve different problems.

Buying rules

Quick rules before buying any UV light

Most UV mistakes happen because the buyer chooses by wattage only and ignores wavelength, distance, surface and use case.

Pick the use case first

Inspection, glow effect, curing and exposure work need different UV products.

Check wavelength

365nm, 395nm and 405nm are not interchangeable for every task.

Match the form factor

Use torches for close inspection, floodlights for wide glow, strips for edges, and bulbs for simple small rooms.

Expect variation

Results depend on material, distance, darkness, surface, angle and product specs.

Important limits

What this guide does not claim

No medical or germicidal claim

This guide is not for medical, hygiene, sterilisation, disinfection or UVC germicidal use. Do not claim UVC benefits unless actual UVC products and documentation exist.

No guaranteed detection

Pet stains, leak dye, marks, documents, gemstones and minerals may or may not fluoresce. UV can help viewing, but it does not guarantee detection or authentication.

No guaranteed curing result

405nm curing depends on resin type, manufacturer wavelength requirement, light power, distance, thickness and exposure setup.

No one-size-fits-all UV product

A UV torch, floodlight, bulb, strip light and curing light are not substitutes for one another. Choose based on the job.
