Makes the room glow
At 395 nm the UV LED lights up fluorescent paint, white fabric and decorations while the room itself stays dark. That contrast is the whole effect.
Wash a wall or pick a feature
It is bright enough for a stage or a garden party and can be angled to cover a whole wall or single out one detail.
Runs cool all evening
The 23.5 x 20.5 x 2.5 cm panel fits without a specialist and runs cool enough to leave on for a full night. The LED is built in, so no bulb to change.

Frequently Asked Questions
What wavelength is the UV?
395 nm, the blacklight range that makes fluorescent paints, white fabrics and party decorations glow strongly while leaving the room itself dark.
What is it designed for?
Parties, stages, clubs and event lighting. It is an effect light rather than room lighting, which is exactly why it works so well for an evening.
How big is the fixture?
23.5 x 20.5 x 2.5 cm, slim enough to mount discreetly and light enough to reposition between one event and the next.
Can I leave it on for hours?
It runs cool enough to stay on through an evening. Do not look directly into the UV source and keep it out of reach of children while it is running.
How is it installed?
Fitting is straightforward and does not call for a specialist. Follow the supplied instructions, switch off at the mains before fitting or cleaning, and angle it where you want the effect.
