XLamp CXB3070
Cree COB 70-106W
Now Available in eTone™ Version: 90 CRI Light Quality at 80 CRI Efficacy
XLamp® CXA2 LED Arrays lead the industry in efficacy and reliability for ceramic-based COB LEDs. Cree CXA2 LEDs easily deliver TM-21 lifetimes well beyond L90 60,000 hours under a wide range of operating conditions. CXA2 LED Arrays share the same physical design as XLamp CXA and CMA LED families, allowing lighting manufacturers to leverage the existing optical, mechanical and electrical design elements to accelerate time to market without additional cost. CXA2 LEDs are now available in an eTone version that delivers beautiful 90 CRI light quality at the same efficacy as today’s standard 80 CRI LEDs.
Product Description
The XLamp® CXB3070 LED Array is a
member of the second generation of
the CXA family that delivers up to 30%
higher efficacy and up to 20% higher
lumens than the first generation in the
same LES. The higher performance
second generation CXA LED Arrays
provide a drop-in performance upgrade
to existing CXA LED designs to shorten
product development time. In addition,
the CXB LEDs also allow lighting
manufacturers to achieve the same
or better performance with a smaller
LES, enabling a smaller, more impactful
luminaire. Available in 2‑step, 3‑step and
5‑step EasyWhite® bins, the CXB3070
LED delivers high lumen output and high
efficacy in a single, easy‑to‑use package
that eliminates the need for reflow
soldering.
The CX Family LED Design Guide
provides basic information on the
requirements to use the CXB3070 LED
successfully in luminaire designs.

Notes
• Cree maintains a tolerance of ±7% on flux and power measurements, ±0.005 on chromaticity (CCx, CCy) measurements and a tolerance of ±2 on CRI
measurements. See the Measurements section (page 21).
• Cree XLamp CXB3070 LED order codes specify only a minimum flux bin and not a maximum. Cree may ship reels in flux bins higher than the minimum
specified by the order code without advance notice. Shipments will always adhere to the chromaticity bin restrictions specified by the order code.
* For 80 CRI minimum LEDs, CRI R9 minimum is 0 with a ±2 tolerance. For 90 CRI minimum LEDs, CRI R9 typical is 60.
** Flux values @ 25 °C are calculated and for reference only.
Packaging
--------------------------------------------------------------------------------------------------------------------------------------
Cree CXB3070 LEDs are packaged in trays of 20. Five trays are sealed in an anti-static bag and placed inside a carton, for a total of 100
LEDs per carton. Each carton contains 100 LEDs from the same performance bin.
