Jelight's Blak-Ray B-100A High Intensity Longwave UV Lamp

is a high intensity 365 nm longwave UV-A lamp designed for fluorescence inspection, non-destructive testing, quality control, leak detection, and laboratory examination work where a compact low-power UV lamp is not enough. Model 95-0044-22 is the 115V version of the B-100A, using a 100 watt longwave UV source with a transformer base and an aluminum lamp head connected by an 8 ft. (2.44 m) cord. The lamp head can be used by hand or positioned in the transformer base for hands-free operation, where it rotates 360 degrees for convenient aiming. With rated UV intensity of 20,000 µW/cm² at 2 in. and 5,000 µW/cm² at 10 in., the B-100A is built for users who need strong, repeatable fluorescence response in inspection and production environments.

Applications

Non-Destructive Testing and Inspection

The B-100A is used for high intensity longwave UV inspection where fluorescent indication, contrast, and operator control are important. It is a strong fit for NDT workflows, fluorescent penetrant inspection support, coating inspection, contamination detection, and general industrial fluorescence examination.

• Non-destructive testing support
• Fluorescence inspection of materials and parts
• Quality control inspection stations
• Coating, adhesive, sealant, and contamination checks

Laboratory and Research Use

Laboratories use 365 nm longwave UV for visualizing fluorescent materials, demonstrating fluorescence behavior, checking samples, and supporting inspection tasks that require a higher-output UV-A source than smaller handheld lamps can provide.

• Fluorescent sample examination
• Laboratory quality checks
• Educational fluorescence demonstrations
• Materials research and process review

Production, Maintenance, and Field Inspection

The handheld lamp head and transformer base make the B-100A useful for both bench inspection and walk-up inspection tasks. The 8 ft. (2.44 m) cord allows the lamp head to be moved around parts, equipment, and work surfaces while keeping the ballast base positioned safely nearby.

• Leak detection using compatible fluorescent dyes
• Maintenance inspection
• Incoming goods inspection
• Process troubleshooting and visual confirmation

Features

• High intensity 365 nm UV-A output supports strong fluorescence response in inspection and quality control applications.
• Handheld lamp head improves operator control when inspecting irregular parts, large workpieces, or hard-to-position samples.
• Transformer base supports hands-free use and allows the lamp head to rotate 360 degrees for flexible aiming.
• Powder-painted aluminum lamp head provides a durable inspection-lamp housing for lab and industrial environments.
• Recognized Blak-Ray B-100 series design supports buyers replacing existing UVP units or standardizing around established UV inspection equipment.
• Serviceable design supports replacement of common wear and optical components, including the 34-0054-01 spot bulb and filter/bezel assembly.

FAQs

What wavelength does the UVP / Jelight B-100A emit?

The B-100A emits 365 nm longwave UV-A, commonly used for fluorescence inspection, leak detection with compatible fluorescent dyes, non-destructive testing support, and laboratory examination.

What is the replacement bulb for the B-100A?

The replacement spot bulb for the B-100A is part number 34-0054-01.

Is the B-100A the same as the B-100AP?

No. The B-100A uses a powder-painted aluminum lamp head. The B-100AP is a related Blak-Ray model with a Cool-Touch housing. Both use the 100W replacement spot bulb,  part number 34-0054-01 and performance is the same except for touch temperatures. 

Can the B-100A be used hands-free?

Yes. The lamp head fits into the transformer base for hands-free use and can rotate 360 degrees when positioned in the base.

What safety protection is needed when using this lamp?

Operators should use appropriate UV-blocking eye and face protection and avoid direct exposure to eyes or skin. This product produces high intensity ultraviolet radiation and should be used only by trained personnel following applicable safety procedures.

Warranty

Labgear supports customers with product selection, replacement lamp sourcing, and assistance confirming model compatibility before ordering. For service questions, replacement bulb needs, or help identifying the correct B-100 series configuration, contact Labgear before purchase so we can verify voltage, housing style, and accessory compatibility.

Ordering

Order the UVP / Jelight Blak-Ray B-100A, part number 95-0044-22, when you need the standard 115V high intensity 365 nm UV-A inspection lamp with aluminum lamp head and transformer base. Before adding to cart, confirm that your facility requires the 115V B-100A configuration rather than the 230V version, extended-cord B-100A/R, or Cool-Touch B-100AP model. For replacement bulbs, accessories, or model confirmation, contact Labgear for assistance.

Add to Cart and add address for shipping costs, or to purchase the Blak-Ray B-100A. Contact Labgear for current availability, lead time, and replacement parts support.
