  1. As royal-blue LEDs are close to the UV range, LEDs are rated by radiometric power (mW) instead of lumens.
  2. Values based on 350mA and a Thermal Pad temperature of 25C.
  3. Viewing angle is the off axis angle from lamp centerline where the luminous intensity is ½ of the peak value.
  4. This is the maximum operating current that we recommend for this LED. Higher drive currents may be possible, but will require careful design of a suitable cooling system.
  5. At the recommended operating current.
  6. Typical thermal resistance from the LED Junction to the bottom of the FR4 board.
  7. This is the value we recommend you use for determining driver input voltage.
* Results will vary depending on the quality of the dielectric material used in the MCPCB base.
