I recently just added a custom water cooling loop to my pc with petg tubing and a 2x5.25" reservoir. This Uv led allow the Uv Reactive Fluid to glow bright. I also don't notice any purple from the led hitting any parts of my pc or clashing with the other light schemes I have going on, This is what I wanted as I've seen pictures of other peoples water cooled setups and I have notice a purple glow. Nice clean look. Nice and bright. Will buy againI used 1/8-Watt 100 Ohm Carbon Film Resistors…
