Black or UV light has a spectrum in ultraviolet between 365 and 420 nanometres (nm). This spectrum ‘excites’ fluorescent and invisible UV pigments.

You must install black lights high up, across the beams at the centre of the room, so that there are no shadows.

Limit other sources of light as much as possible as they may disrupt the UV effect.


We’re based in Paris and create events in black and invisible light.

We create kits for anything from 200 to 5,000 people in clubs, halls, castles and more.
