Jelight 4 W 302 nm Midrange UV-B Replacement Tube

is a 4 W replacement ultraviolet tube that emits midrange UV radiation at 302 nm. Designed for compatible Jelight EL Series and 3UV lamps, it restores UV-B output for laboratory inspection, fluorescence examination, and equipment maintenance.

Applications

Midrange Fluorescence Inspection

Restores 302 nm UV excitation in compatible lamps used to examine fluorescent minerals, dyes, specimens, and other UV-responsive materials. The replacement tube supports continued midrange fluorescence inspection when the original tube loses output or requires replacement.

Laboratory Sample Examination

Provides replacement UV-B illumination for compatible laboratory lamps used in sample examination and analytical inspection. Suitable for equipment requiring a 4 W, 302 nm midrange UV light source.

UV Equipment Maintenance

Replaces worn or damaged 302 nm tubes in compatible Jelight EL Series and 3UV equipment. Proper tube replacement helps maintain the intended performance of the existing lamp assembly.

Features

• Produces midrange ultraviolet radiation at a primary wavelength of 302 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 EL Series and 4 W 3UV lamp configurations.
• Supplied as an individual replacement tube rather than a complete UV lamp assembly.

Frequently Asked Questions

Which Jelight UV lamps use replacement tube 34-0071-01?

The 34-0071-01 is compatible with the UVM-14, UVM-24, and UVLM-24 EL Series lamps, as well as the 302 nm position in the 3UV-34. Verify the equipment model and replacement tube requirements before ordering.

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

The UVM-14 and UVLM-24 each require one 34-0071-01 tube, while the UVM-24 requires two. Other tube positions in these lamps may use different UV wavelengths or white-light tubes.

Can this tube replace a 254 nm or 365 nm UV tube?

No, the 34-0071-01 produces UV-B radiation at 302 nm and is not a direct substitute for 254 nm UV-C or 365 nm UV-A tubes. Matching physical dimensions do not guarantee wavelength or equipment compatibility.

What precautions should I take when replacing a 302 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-B 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.
