With the increase in popularity of LED lighting, many people are confused when it comes to choosing an LED lamp.
First we should understand that the quality and price of lamps are determined by four components: LED chip, LED driver, Heat Sink and Printed Circuit Board (PCB).
1. LED Chip
One of the two most important components of an LED lamp, chips come in a wide range of performance standards and consequently the price will vary depending upon the brand of chip used by the manufacturer. While high performance lamps use CREE or OSRAM; the price may be a little rich for most consumers. Instead, you may want to opt for a lamp with a chip from Bridgelux, Samsung or Epistar to name but three affordable, quality chips.Use of a good quality chip results in beautiful color, (as gauged by its color temperature and color rendering index - CRI), as well as high luminous efficacy (a measure of how well a light source produces visible light).
