LED Ring of Light

This Board is designed to fit into the top of the case. It snaps onto the existing mounting holes and will illuminate a custom or cleared jewel. You can also use a little bit of hot glue to hold it in place if you feel it necessary.

This listing is for a fully populated board in Red, Green or Blue LED's.

There is also an unpopulated board if you would rather install your own LED's.
No LED's, resistors, or wires are included with an unpopulated board.

If you don't know what value resistor to use, this RESISTOR CALCULATOR will help you find the correct value that you should use. It gives a higher and lower value. I recommend you take the higher value to help protect the LED's and make them last longer. The lower value will make them a little bit brighter but will also contribute to a shorter lifespan. This calculator will also recommend some higher than normal wattage's however this board is designed to fit 1/4 watt resistors.

• SUPPLY VOLTAGE: The supply voltage will be 12v or 5v depending on which voltage supply line you intend to use.
  (Just because Kekule labeled the positive (+) terminal as "12V" doesn't mean you have to use 12v. 5v is completely acceptable too.)
  
• LED CURRENT: A single LED's current is normally 20mA.
• COLOR, VOLTAGE DROP: The voltage drop varies from color to color and from manufacturer to manufacturer so please see the datasheet on the LED's you purchase for this value. This calculator site provides generic values but it's best to see the datasheet on the LED's that you source for this project to be 100% sure.
  
• NUMBER OF LED'S: On this ring of light PCB, each LED has its own resistor so the number of LED's will be calculated for 1.
• RESISTOR PRECISION: It's recommended to leave this setting set at the calculator's default of 5%.
