UNIVERSAL HUB 5mm multicolor Combo Of 50PCS LED LIGHT 10 Piece Each Color Red Green Blue Milky White Yellow Mini Bulb, flanged

About this item

• Each LED should have a 'Forward Voltage' label that specifies the amount of voltage needed to carry power and create light.
• You can power any of the 5mm LEDs except the reds and yellows without bothering about keeping track of the current.
• The current ratings of 5mm LEDs are substantially lower, often around 15-30mA, and we may limit the current by connecting a resistor to the LED.
• Input Voltage = LED Vf + Resistor Voltage Resistor Voltage = Input Voltage – LED Vf Voltage Across Resistor = 4.5V – 3.4V
• 5mm LEDs brightness is usually measured in millicandelas (mcd), but there is much more to this than just putting a certain number of brightness on any LED.
