According to a recent Consumer Reports survey, latest tests have indicated that light-emitting diode bulbs (LEDs) from Philips, EcoSmart, and GE have received higher scores when compared to compact fluorescent lightbulbs (CFLs).
A majority of individuals in America have adopted energy-efficient CFLs or LEDs, among which 75 % use CFLs.
Complete report and ratings of lightbulbs can now be viewed online at ConsumerReports.org and in Consumer Reports of October 2012 issue to be released on September 4th.
LEDs are widely preferred due to their 75% less energy consumption, instant brightness and the ability to remain unchanged when turned on and off, often.
Consumer Reports' tests recognized several affordable CFLs from Sylvania, EcoSmart, Feit, Utilitech, and GE. Replacement of 60-W incandescent bulbs with CFLs will reduce energy costs.
Consumer Reports has detected four lightbulb letdowns and means to prevent them.
- Weird light color: Light color is represented by its kelvin temperature. Higher kelvin (K) number promotes a cool effect. Warm light of an incandescent can be achieved through CFL or LED marked 2700 K on the Lighting Facts label. The light is whiter at 3000 K, and cool and bright white at 3500 K to 4100 K. Bulbs marked 5000 K to 6500 K will give blue light.
- Dim bulbs: The Lighting Facts label on the packages of CFLs and LEDs indicate the number of lumens. Increased lumens promote brightness of bulb. Low watt- bulb ensures energy efficiency.
- Unflattering light: Bulbs with a higher CRI produces more brightness.
- Early burnout can be dealt by returning the bulb to the retailer, like Lowe's or Home Depot or by contacting the producer. The bulbs need to be compatible with existing fixtures.
