Cree XLamp XB-D LED 75-watt Equivalent A19 Lamp Reference Design

Cree XLamp XB-D LED 75-watt Equivalent A19 Lamp Reference Design. This reference design details the design of a 75-watt equivalent A19 replacement lamp using Cree's XLamp XB-D LED. The XLamp XB-D LED is designed specifically for high lumens/dollar applications, such as the price-sensitive replacement lamp market. This XB-D A19 lamp is intended to be a replacement for incandescent A19 lamps in omnidirectional indoor lighting applications. These lamps are sufficient for directional applications such as a floodlight but do not replicate the omnidirectional light pattern of an incandescent lamp. This reference design betters the snow cone style design to produce a lamp that matches the light pattern of an incandescent, enabling its use in omnidirectional applications and also enabling it to meet ENERGY STAR intensity distribution requirements
