Prisma combines true 365nm UV output for long and wide throw performance with the control and efficiency of LEDs. Because Prisma uses high quality, medical grade LEDs that emit UV light in the 365nm range, no visible light is emitted, meaning only the UV reactive material glows and nothing else. Prisma offers other advantages over traditional UV LED lights as well. Prisma effects use durable LEDs of the highest quality with special silicone lenses that are UV resistant and slow to degrade. Most plastic lenses on traditional UV lights will brown and deteriorate over a few years of use but Prisma’s silicone lenses will last for 25 years or more.
