Jelight Blak-Ray® B-100AP

is a 100 W high-intensity ultraviolet lamp producing 365 nm longwave UV-A illumination for fluorescence inspection, non-destructive testing, and fluorescent leak detection. Its heat-resistant Cool-Touch™ plastic housing provides improved handling comfort during extended inspection work, while its detachable lamp head supports handheld or hands-free operation. Standard and extended-cord configurations are available.

Applications

Fluorescence Inspection

Provides concentrated 365 nm UV-A illumination for examining fluorescent dyes, coatings, markings, and other UV-responsive materials. The high-intensity output supports visual identification of fluorescent indications during laboratory, industrial, and quality control inspections.

Non-Destructive Testing

Supports fluorescent non-destructive testing procedures where longwave ultraviolet illumination is used to reveal indications on inspected components. Suitability depends on the fluorescent materials, inspection conditions, and applicable testing requirements.

Fluorescent Leak Detection

Used with compatible UV-responsive tracer dyes to help identify leaks in mechanical systems and industrial equipment. The concentrated UV-A output makes fluorescent dye indications easier to distinguish during inspection and maintenance procedures.

Features

• High-intensity 100 W mercury-vapor lamp provides concentrated 365 nm longwave ultraviolet illumination.
• Manufacturer-listed UV intensity of 20,000 µW/cm² at 50.8 mm (2 in) and 5,000 µW/cm² at 254 mm (10 in).
• Heat-resistant Cool-Touch™ plastic housing reduces external housing temperatures compared with aluminum lamp-head designs.
• Detachable lamp head with pistol-grip handle supports handheld operation or hands-free positioning on the transformer base.
• Lamp head rotates 360° when mounted on the transformer base for adjustable inspection positioning.

Frequently Asked Questions

What is the difference between the B-100A, B-100AP, and B-100AP/R?

All three models provide high-intensity 100 W, 365 nm UV-A illumination. The B-100A features a powder-coated aluminum housing, while the B-100AP uses a heat-resistant Cool-Touch™ plastic housing for improved handling comfort. The B-100AP/R uses the same Cool-Touch™ housing with extended 6.1 m (20 ft) primary and secondary cords instead of the standard 2.44 m (8 ft) cords.

What types of fluorescence inspection can the B-100AP perform?

The B-100AP provides 365 nm longwave ultraviolet illumination for examining UV-responsive dyes, coatings, markings, and fluorescent indications. Applications include fluorescence inspection, compatible non-destructive testing procedures, and fluorescent leak detection. Inspection effectiveness depends on the fluorescent materials, operating conditions, and applicable testing requirements.

How long does the B-100AP take to warm up and restart?

The lamp starts immediately when cool but requires approximately five minutes to reach full brightness. After shutdown, the mercury-vapor bulb typically requires four to eight minutes to cool before restarting.

What safety precautions should be followed when operating or servicing the B-100AP?

The B-100AP produces high-intensity ultraviolet radiation that can harm the eyes and skin. Wear appropriate UV-protective eyewear, minimize direct skin exposure, and never look directly into the illuminated lamp. Although the Cool-Touch™ housing reduces external temperatures, the internal bulb becomes extremely hot during operation. Never operate the lamp with missing or damaged filter glass. Disconnect power and allow the lamp to cool completely before servicing, and follow applicable procedures for handling and disposing of mercury-containing bulbs.
