LUXEON Rebel White - Philips Lumileds

Electrical Characteristics at 350 mA for LUXEON Rebel - Thermal Pad Temperature = 25ÂșC
Part No - LXM3-PW71
  • Nominal CCT - 3000K
  • Typical CRI - 85
  • Typical Luminous Flux - 77 lm
  • Forward Voltage Vf - Typ - 3.00 V
  • Color Temperature - CCT - 3045K
  • Typical Viewing Angle - 120 Degrees
Correlated Color Temperature (CCT) - The phrase use to describe the temperature at which a Planckian Black Body Radiator and an illumination source's appear to match, usually specified in Kelvin (K).

CRI or Color Rendering Index - The calculated rendered color of an object. The higher the CRI (based upon a 0-100 scale), the more natural the colors appear. Natural outdoor light has a CRI of 100. Common lighting sources have a large range of CRI.

Flux - The sum of all the lumens (lm) emitted by a source (see lumen).
