It's no secret that the UV spectrum isn't well known for it's brilliance as you can see below. The spread on the LEDs is wide and directed into three separate spotlight style beams. This is perfect for applications where specifically directed ultra violet light is necessary. It's the LED Dual Fan Grill in Blue/Blue. This fan grille has two rings of brilliance housed in clear acrylic as well as a PCI plate that has a very welcomed attached rocker switch (something many companies forget to include). Lengthy bolts for installation are also provided.
