Lextar Debuts 150 lm/W COB in Typical Conditions Tj = 85°C

Lextar launches Version 4 COB lineup at Light + Building 2016, bringing 15% higher flux efficacy (up to 150 lm/W), quality and cost competitive products for versatile lighting applications from indoors to outdoors. The performance upgrade is based on improvements in both chip die development and also package design. The new lineup also provides wide range of luminous flux and various colors, and wide selection of connectors and optical part solutions. Thanks to Lextar’s vertical integration capability, it provides high quality and rapid development.

Lextar, the LED vertical integration manufacturer, will launch Version 4 COB lineup using private chip technology to integrate package design. The new series provides high performance (up to 150 lm/W), high quality and cost competitive features for lighting fixture manufacturers.

Version 4 COB effects to make more benefits for luminaire design:

The Version 4 COB provides wide range of luminous flux in various light emitting surface (LES) from LES 9.8mm to LES 22mm for both indoor and outdoor applications.


Lextar Version 4 COB offered 3-step MacAdam ellipse color definition with wide range of color temperatures (CCT) from 2700K to 6500K for CRI 80 and CRI 90. Below B.B.L. models are also available and offer diversified options for luminaire design. Higher flux efficacy also provides benefits with lower power consumption. The lumen output will be increased and enhance system efficiency of luminaire.


In terms of mechanical design, Version 4 COB provides wide selection of connectors and optical part solutions for quick optical design and easy assembly. The improved flux efficacy with the good thermal design can lower heat generation with good heat transfer. Therefore, the luminaire system cost and weight can be reduced resulting from the simplified thermal design.
