01NIGHT LIGHTS & AMBIENT LIGHTING

Ultraviolet clarity for hidden details

A compact cylinder of black glass, this bulb transforms ordinary illumination into a tool for discovery. Its focused beam reveals textures and patterns that remain invisible under standard white light, adding a layer of intrigue to any room it occupies.

Designed for both practical verification and atmospheric effect, the 40-watt unit suits those who appreciate precision in their lighting. It serves equally well in a study for inspecting documents or in a lounge where neon hues dance on the walls.

02OPTICS

Focused ultraviolet emission at 365 nanometres

The core function is the precise wavelength of 365 nanometres, falling within the UV-A spectrum. This specific frequency excites fluorescent materials without flooding the surrounding space with visible glare. The result is a sharp contrast between reactive surfaces and their background, allowing subtle variations in material composition to become clearly visible to the observer.

04UTILITY

Revealing hidden marks and security features

Beyond aesthetic application, the bulb acts as a diagnostic instrument. It illuminates security markings on identification cards and currency, making micro-print and watermarks legible. In domestic settings, it exposes pet stains on carpets and upholstery that are otherwise imperceptible, aiding in thorough cleaning routines and quality checks for textile care.

05SPECS

Dual voltage operation and low power draw

Rated at 40 watts, the unit delivers 15 lumens of luminous flux, prioritising spectral accuracy over raw brightness. It supports both 110V and 220V inputs, offering flexibility for international use. The product itself weighs approximately 80 grams, while the packing carton measures 19 x 6 x 5 cm and adds 0.18 kg to the total shipping weight.

Highlights

1, 1. Black Light (BLB): 40-watt black light (BLB) emits ultraviolet (UV-A) light with a wavelength of 365 nm, which is very suitable for illuminating reactive surfaces without illuminating the surrounding area.
Holiday Lighting: Suitable for creating luminous effects with real white and neon colors in parties, clubs and Halloween decorations.
Verification and Detection: It is also very suitable for verifying the security functions on ID cards and currencies. Used to detect pet stains invisible to the naked eye on carpets or furniture.
Wide Application: Agricultural breeding, UV curing, fluorescence detection, currency checking, stage decoration, hand shadow dance, etc.
