Use-case guide

The wrong UV wavelength creates the wrong result

UV buyers often compare price and wattage first, but wavelength and use case should come first. 365nm is suited to inspection and fluorescence, 395nm to visible blacklight glow effects, and 405nm to compatible resin-curing applications.

Technical buying guide

How UV wavelength and product format work together

A wavelength determines application fit. A product format determines the physical setup: torch, floodlight, spotlight, bulb or strip.

365nm

Best for inspection and fluorescence tasks such as gemstones, minerals, leak dye, pet stains and document checking.

395nm

Best for visible blacklight glow effects such as glow parties, neon paint, fluorescent posters, clubs, stages and decor.

405nm

Best for compatible resin curing and 3D printing post-curing workflows.

Product format

Torches are for portable inspection. Floodlights are for wide coverage. Spotlights are for focused effects. Bulbs and strips are for compact glow.

FAQ

UV light buying guide FAQs

What is the difference between 365nm, 395nm and 405nm UV light?

365nm is best for inspection and fluorescence, 395nm is best for visible blacklight glow effects and 405nm is used for compatible resin curing workflows.

Which UV light is best for glow parties?

Choose 395nm UV blacklights such as floodlights, spotlights, bulbs and strip lights.

Which UV torch is best for inspection?

Choose a 365nm UV torch with a black filter for inspection-focused tasks.

Which UV light is used for resin curing?

Use 405nm UV lights when the resin or coating is compatible with 405nm exposure.

Should I choose by wattage first?

No. Choose by use case and wavelength first, then choose wattage based on area, distance and workflow.
