XLamp XB-D

Smallest lighting-class LED enables dramatically lower system cost

Enabling the next generation of mainstream LED lighting adoption, the XLamp XB-D LED is ushering in a new era of price and performance for lighting-class LEDs. Designed to enable lower system costs for lighting manufacturers, the XLamp XB-D LED doubles the lumens per dollar of previously available LEDs.

Leveraging Cree's latest silicon carbide technology and expertise, the XB-D LED delivers up to 139 lumens and 136 lumens per watt in cool white (6000K) or up to 107 lumens and 105 lumens per watt in warm white (3000K), both at 350 mA and 85°C.

Cree Product Characterization Tool (PCT)

For help identifying the best Cree Xlamp® LEDs for your lighting-system design

The Cree Product Characterization Tool (PCT) allows you to select from multiple lighting-system design parameters to compare up to three LED models simultaneously.
Try the Product Characterization Tool (PCT)

For all valid LED drive currents, the PCT quickly and easily does the following:

  • Shows all critical LED design parameters, such as luminous flux and efficacy, for selected LED models
  • Performs de-rating calculations based on junction temperature (Tj)
  • Calculates LED valuations, such as lumens per dollar (lm/$)
  • Estimates simple LED design parameters, such as the number of LEDs required and total power consumption

The PCT uses specifications and characteristics from LED data sheets to accurately compare LED parameters with changes in flux, price and junction temperature. The PCT can compare up to three LED models side-by-side to aid in making critical design choices.
