Abstract

Product Identification

The devices subjected to teardown for this work are five A19 LED light bulbs: Feit 7.5W, Pharox 300, GE Energy Smart, Sylvania Ultra LED and Philips Ambient LED. The Philips is a 60W equivalent bulb, others are 40W equivalent.

Standard A19 format light bulbs, found today in most lamps and luminaires, are now available using LED technology. They retail between $20 and $40 per 40W or 60W equivalent light bulb. But why so expensive? Is there real value at this price? Why are some bulbs twice the price of the others? Some bulbs are dimmable, others not, and some only with specific dimmers. They all advertise 25,000 to 50,000 hours expected lifetime. This is based on three to four hours daily usage. If used appropriately and sparingly, you might expect your light bulb to outlive you.

In our scientific quest for answers, we have torn apart five A19 LED light bulbs. The Philips is a 60W equivalent at 12.5W and 800 lumens. The others, Pharox, Feit, Sylvania and GE, are all 40W equivalent bulbs.
