This new fan design uses a UV sensitive dual color fan housing with UV LEDs. The UV LEDs illuminate the entire fan, creating a very unique look. The fan is constructed using two different colors of UV reactive material—one color for the fan blades and one for the outer housing. This creates quite an amazing effect when the fan is powered on. This great UV effect is very difficult to capture with a camera—the fans are much more impressive in person. The fans are great for power supplies or any place where it was conventionally impossible to get UV light.
