Jelight UVLS-28 8 W 254/365 nm EL Series UV Lamp

is a dual-wavelength ultraviolet lamp designed for fluorescence inspection, laboratory examination, and applications requiring both 254 nm shortwave and 365 nm longwave UV illumination. Equipped with one 8 watt 254 nm tube and one 8 watt 365 nm tube, the UVLS-28 allows samples to be examined under two distinct ultraviolet wavelengths using a single durable EL Series lamp.

Applications

Dual-Wavelength Fluorescence Inspection

Provides both 254 nm and 365 nm ultraviolet excitation for examining materials that may exhibit different fluorescence responses under shortwave and longwave UV illumination.

Laboratory and Analytical Work

Suitable for sample examination, fluorescence observation, laboratory inspection, educational demonstrations, and analytical procedures requiring 254 nm or 365 nm ultraviolet light.

Mineral and Specimen Examination

Useful for examining fluorescent minerals, biological specimens, and other materials whose appearance or fluorescence response varies with ultraviolet wavelength.

Hands-Free UV Inspection

Can be paired with a compatible lamp stand or UV viewing cabinet for stationary illumination during repetitive inspection, sample handling, and fluorescence observation.

FAQs

Can the UVLS-28 be used hands-free?

Yes. The UVLS-28 can be paired with the J-138 Lamp Stand, part number 18-0063-01, or used with a compatible UV viewing cabinet for stationary sample examination.

What safety measures should be taken when using the UVLS-28?

Use appropriate UV-protective eyewear and face protection when operating the lamp, and minimize direct exposure of the eyes and skin to ultraviolet radiation. Shortwave 254 nm UV requires particular care due to its potential to cause eye and skin injury. Do not look directly at the UV source, and follow applicable laboratory, workplace, and site-specific UV safety procedures.
