by Editors of ConsumerReports.org
Our AssessmentConsumerReports.org subjects 48 light bulbs, including CFLs, LEDs and a couple of halogen bulbs, to "life testing." The process includes cycling them on and off repeatedly until they reach 3,000 hours of use. Editors measure how well each bulb holds up and compare that to its claimed lifespan. They also measure brightness, efficiency, light distribution, light color and the time it takes each bulb to reach full brightness after being switched on.
Light Bulb Reviews
by Editors of the Good Housekeeping Research Institute
Our AssessmentThe Good Housekeeping Research Institute tests 28 energy-saving light bulbs, grading each one from A to F. To evaluate longevity, bulbs are set to blink on and off at 15-second intervals over a long period. Testers also rate the bulbs' brightness, light distribution, warm-up time, efficiency and light quality. Editors give the highest overall ratings to six LED and halogen bulbs, but they say CFLs offer the best value.

New Reasons to Change Light Bulbs
by David Pogue
Our AssessmentTechnology columnist David Pogue tests six brands of LED light bulbs in his home, and reports on their light quality, appearance and value.

Pogue recommends the Cree bulbs for their "superior design and low price" -- as low as $6 each.
Good Bad Bulbs – Fluorescent Lighting & LED Lighting
by Don Rathbun

Reviews are brief, and touch on light quality, shape and value.
Cree's LED Replacement for the 75-Watt Bulbs You Can't Buy Anymore
by David Agrell
Our AssessmentDavid Agrell of Popular Mechanics reviews the Cree 75-watt Replacement LED, introduced in December 2013. He notes that it's fully dimmable, produces a warm white light, comes with a 10-year warranty and "could save you $170 in energy costs over its 23-year lifetime." Its one drawback is a $23 price tag, but Agrell says the bulb is expected to earn Energy Star certification, qualifying it for rebates that could cut the price significantly.

Our AssessmentThis popular home blog presents a roundup of 10 LED bulbs and their most appropriate uses.

LED & Other Light Bulbs
by Contributors to BestBuy.com

Light Bulb Buying Guide
by Ry Crist
Our AssessmentThe light bulb buying guide at CNET is the most detailed we've seen. It doesn't recommend specific products, but it does cover the pros and cons of the four basic bulb types -- LED, CFL, incandescent and halogen -- in exhaustive detail.

GE Develops LED Light Bulb That Lasts 17 Years
by David Saetang
Our AssessmentDavid Saetang, a writer for PCWorld magazine, discusses the pros and cons of the GE Energy Smart LED bulb but doesn't conduct any hands-on testing. GE claims the bulb lasts up to 17 years, and its odd, spiky design helps distribute light better than older LED bulbs do. Its biggest drawback is a hefty price of $40 to $50, but Saetang says the bulb will pay for itself over the years in energy savings.
