Bamboozled By A Fake COB? Part 2

Update: Summer, 2018

The original blog – Bamboozled By a Fake COB? – was posted back in the fall of 2016.  A lot of new products have been released since then, and we wanted to provide updated guidance to help ensure you are purchasing a true Bridgelux product.

First things first

Always purchase products from an approved supplier or distributor.  A list of where to buy our products is available here

Buyer beware!  Fraudulent websites have appeared where they give the impression they are authorized Bridgelux resellers that accept orders and credit card payments, but then fail to fulfill orders with website ownership being unclear.  Always buy Bridgelux products from authorized, trusted resellers listed here on the Bridgelux website.

Understand the language

We know it’s confusing, but some companies will make a product using a Bridgelux chip or die and say that it’s a Bridgelux COB.  These COBs are not considered Bridgelux products because they are not COBs that are actually manufactured (packaged) by Bridgelux.  The packaging (manufacturing) process, technology, materials and quality controls used by Bridgelux to manufacture products is industry leading and is based on over a decade of experience.  Bridgelux branded chips and die are sold in various performance classes.  In addition to having industry-leading packaging capabilities, Bridgelux COBs are always built with the best, highest performance Bridgelux chips or die. The same benchmark of quality does not exist with COBs that were not manufactured (packaged) by Bridgelux.  To purchase authentic, Bridgelux branded COB products, you need to purchase them from an approved supplier or distributor
