Blacklight/UV FX
Often referred to as Longwave Ultra-Violet or ‘UV A’. Black lights are a specialised type of lighting unit that generates a safe form of UV light invisible to the human eye.
The frequency of UV light emitted by Black light units should ideally be 365-370nm; exactly the right frequency to make UV Revealing products such as ROSCO Flourescent Paints fluoresce brightly and energise Glow-in-the-Dark products, so they perform at their very best. Black lights are considered safe for use in the home as well as theatres and night clubs etc.
