Jelight 4 W 254 nm Shortwave UV-C Replacement Tube

is a 4 W replacement ultraviolet tube that emits shortwave UV radiation at 254 nm. Designed for compatible Jelight Compact, EL Series, Mini, and multi-wavelength UV lamps, it restores UV-C output for laboratory inspection, fluorescence examination, and equipment maintenance.

Applications

Shortwave Fluorescence Inspection

Restores 254 nm UV excitation in compatible lamps used to examine fluorescent minerals, specimens, and other UV-responsive materials. The replacement tube supports continued shortwave fluorescence inspection when the original lamp loses output or requires replacement.

Laboratory Sample Examination

Provides replacement UV-C illumination for compatible laboratory lamps used in sample examination and analytical inspection. Suitable for equipment requiring a 4 W, 254 nm shortwave light source.

UV Equipment Maintenance

Replaces worn or damaged 254 nm tubes in compatible Jelight Compact, EL Series, Mini, and multi-wavelength UV equipment. Proper tube replacement helps maintain the intended performance of the existing lamp assembly.

Features

• Produces shortwave ultraviolet radiation at a primary wavelength of 254 nm.
• Designed as a 4 W replacement tube for compatible Jelight UV equipment.
• Features a linear T5 configuration with a G5 miniature bi-pin base.
• Supports compatible Compact, EL Series, Mini, and multi-wavelength UV lamps.
• Supplied as an individual replacement tube rather than a complete UV lamp assembly.

Frequently Asked Questions

Which Jelight UV lamps use replacement tube 34-0003-01?

The 34-0003-01 is compatible with the 254 nm positions in the UVG-11, UVGL-25, UVS-14, UVS-24, UVLS-24, and UVG-4, as well as specified 4 W multi-wavelength equipment. Verify the equipment model and replacement tube requirements before ordering.

How many replacement tubes are required for an EL Series UV lamp?

The UVS-14 and UVLS-24 each require one 34-0003-01 tube, while the UVS-24 requires two. Other tube positions in these lamps may use different UV wavelengths or white-light tubes.

Can this tube replace the split-wavelength tube in a UVGL-15 lamp?

No, the UVGL-15 requires replacement tube 34-0004-01, which combines 254 nm and 365 nm operation in a single tube. The 34-0003-01 is a dedicated 254 nm UV-C tube and is not a direct replacement.

What precautions should I take when replacing a 254 nm UV tube?

Disconnect the equipment from power and allow the tube to cool before replacement. Follow the equipment manual, handle the glass carefully, and ensure appropriate UV shielding and protective equipment are in place before operation. Never look directly at an exposed UV-C source.

How should an old or broken UV fluorescent tube be disposed of?

Handle used tubes as potentially mercury-containing fluorescent lamps and follow applicable recycling or hazardous-waste requirements. If a tube breaks, follow appropriate mercury-lamp cleanup procedures rather than treating the fragments as ordinary glass waste.

Warranty

This product is covered by a 12-month warranty against defects in materials and workmanship. Inspect the product before use and contact ScienceLighting support if any defects or issues are identified.
