This Philips AmbientLED A19 60W LED Energy Saving Light Bulb Can Last 20 Years.

This new Philips 60W LED light bulb will last for 20 years. Launch on Earth Day 2012 to replace the 60W incandescent bulb, it cost between USD20 to USD60.

This LED bulb also goes by the trade name of myAmbiance LED bulb for a E27 socket, retailing at S$78.10.

The unique design allows the normally directional LED light to be emitted from all sides of the bulb giving it the same illumination pattern as a incandescent bulb. This allows it to directly replaces all 60W incandescent bulb in most lighting applications.

This LED bulb is designed by Philips for the L Prize challenge in the U.S:

Requirements for the 60 Watt incandescent LED replacement, as laid out by DOE, include:

• Efficacy of more than 90 lumens per watt, exceeding the efficiency of all incandescent and most compact fluorescent sources today, ranging from 10 to 60 lumens per watt
• Energy consumption of less than 10 watts as compared to a 60 Watt incandescent
• Output of more than 900 lumens, equivalent to a 60 Watt incandescent light bulb
• Lifetime of more than 25,000 hours, which is 25X greater than a typical incandescent bulb
• Color Rendering Index (CRI) greater than 90, which is a high measure of lighting quality
• Color Temperature between 2700 – 3000 Kelvin, which is “warm” white light comparable to incandescent

The Results

	L Prize Requirement	Philips Result
Luminous flux (lumens, lm)	> 900 lm	910 lm
Wattage (W)	≤ 10 W	9.7 W
Efficacy (lm/W)	> 90 lm/W	93.4 lm/W
Correlated color temperature (CCT)	2700 – 3000 K	2727 K
Color rendering index (CRI)	> 90	93
