The new line-up of diodes is the brightest SMD LEDs offered in the industry today, with up to 450 millicandelas (mcd) typical at 555 to 660 nanometers (nm).
By achieving 10 times the brightness of standard LEDs, the new U-series attains the same level of luminance at 1/10 power consumption, 4 milliwatts (mW)(2 milliamperes (mA)) at 260 millicandelas (mcd).
