Introducing super-bright LEDs and calculating their necessary resistors

A super-bright LED is a light-emitting diode (LED) that glows with high intensity, higher than regular LEDs. LED brightness (light intensity) is calculated in millicandelas (mcd). Bear in mind that 1,000 mcd equals 1 candela. Candelas typically measure how much light is generated at the light source, in this case, an LED, but candelas can be used to measure other light sources, such as light bulbs. The super-bright LED that we use in this chapter is rated as 6,000 mcd, emitting a nice and powerful orange glow, which is quite bright when connected to a proper current-limiting resistor. In comparison, typical LEDs are rated at a range of about 50 to 200 mcd.

Super-bright LEDs have a special design to increase light diffusion by using a transparent glass coating and reflective material. However, some super-bright LEDs have a reduced viewing angle (the observation angle with the LED light looks more intense) of...
