Description

The Cree XLamp® XP-E2 White LED is Cree's newest version of the older XLamp XP-E.  Unlike the original XP-E, the XP-E2 is built from the SC3 technology platfrom and can boast higher lumens per watt and lumens per dollar.  This XP-E2 White LED has an identical foot-print (3.45mm square) as the original XP-E, but by using silicone carbide SC3 technology Cree has increased lumen output by more than 20% and doubled the lumens per dollar over the original XP-E.  The XP-E2 White LED is designed for high-lumen lighting that can range from indoor to outdoor, to portable and lamp retrofits.

LED Star MCPCB

We offer the XP-E2 White LED in two metal core printed circuit board (MCPCB) versions: a single (1-Up: 1 LED) and triple (3-Up: 3 LEDs). The 1-Up is a single XP-E2 White LED reflow soldered to a 20mm hexagonal (LED Star) MCPCB. The MCPCB has four large solder pads for easy solder connections. The 3-Up is three (3) XP-E2 White LEDs reflow soldered in-series to a 20mm hexagonal MCPCB. The 3-Up MCPCB has two solder pads for connections, mounting holes for secondary carclo optics and a center hole for wires or securing the LED star to a heat sink.

Correlated Color Temperatures (CCT)

The XP-E2 LED is offered here in Cool-White (5000K), Neutral-White (4000K) and Warm-White (3000K).

Secondary Optics

Both versions (1-Up & 3-Up) of the XP-E2 White LED are designed to work with secondary optics from Carclo; Carclo is a leader in molded poly-carbonate lens systems. The 1-Up secondary lens system combines a plastic holder and lens that sits on top of the 1-Up MCPCB, while the 3-Up optic is a one-piece system with three legs that sit down into corresponding holes on the 3-Up MCPCB. These secondary optics focus light into narrow, medium, wide and elliptical patterns. More information is available on optics that mate with the XP-E2 White LED on this page under the Accessories tab above.

Images, Part Numbers & Notes

Selecting the LED options near the 'add to cart' button displays the corresponding product image and part number. For referencing detailed specifications there are tables and downloadable documentation below.  Important Note: Unless noted otherwise the specifications listed are for a single White XP-E2 LED. This means that in most cases the values need to be tripled for applications with the 3-Up version. For Example, if the forward voltage listed is 3.15V @ 350mA, then the 3-Up version would be 9.45V.
