The difference between UV curing lamps and ultraviolet lamps

UV curing lamps are a type of ultraviolet lamps. The main difference between them lies in their wavelengths and applications. Using them together is ineffective and dangerous.

What's the difference in wavelengths?

Curing lamp: Mainly emits long-wave ultraviolet (UVA), with wavelengths concentrated at 365nm, 385nm or 395nm. It is specifically used to trigger chemical reactions in photosensitive materials.

Disinfection lamp: Mainly emits short-wave ultraviolet (UVC), with a wavelength of approximately 253.7nm. This wavelength band has the strongest disinfection ability, but has weak penetration and cannot be used to cure glue. 

What can they be used for?

Curing lamp: Commonly used in industrial printing, furniture coating, nail art therapy, and 3D printing. When used with UV glue or ink, it can harden within a few seconds.

Disinfection lamp: Used in hospital operating rooms, household room air disinfection, and water treatment. It utilizes ultraviolet rays to damage the DNA structure of microorganisms and cannot be used to cure materials. 

Is it safe to use?

Protection is needed: Both types of lamps can cause eye and skin damage when exposed for a long time, leading to redness or keratitis. It is recommended to wear goggles when operating. 

Disinfection is more dangerous: When the disinfection lamp is turned on, one must leave the room to avoid ozone poisoning and burns; the curing lamp is usually irradiated inside the equipment or locally, and the risk is relatively controllable.
