n:vision 23W (100W equivalent) compact fluorescent
New bill would mandate that light bulbs produce 120 lumens per watt by 2020

It looks as though energy efficiency is still a big priority for municipalities and countries across the globe. We've already detailed energy-efficient LED lighting efforts put forth by Raleigh, NC. We've also discussed how Australia and the European Union (EU) plan to get rid of incandescent light bulbs by 2009. The United States is also moving towards ushering out inefficient lighting with H.R. 1547, which was published on March 15, 2007.

The bill (PDF), which was submitted by California representative Jane Harman, indicates that light bulbs which have an overall luminous efficacy of 60 lumens per watt (lm/W) will be prohibited by January 1, 2012. The energy requirements get progressively steeper every four years. On January 1, 2016, the requirement will grow to 90 lm/W and will reach 120 lm/W by 2020.

A traditional 100W tungsten incandescent light has an overall luminous efficacy of 17.5 lm/W. A 23W compact fluorescent (100W equivalent) has an overall luminous efficacy of 60 lm/W.

Exemptions could be made by the Secretary of Energy for certain applications where it wouldn't be feasible to use energy-efficient lighting. These include applications related to military, medical or matters of public safety.

If an exception is made by the Secretary of Energy, that still doesn't give entitle the recipient to a free pass to continue using outdated technology. The exemption will only be in effect for two years after which the current enacted requirement will have to be adhered to.

The bill also notes that consumers and businesses will be given incentives to encourage the use of energy efficient light bulbs.

i'm just saying that the average life of the CFL is not what the box says

I agree completely. I have these bulbs throughout my entire house and I love the bright white light they put out and the significant energy savings. However, the "guaranteeed 7 years" statement is a joke. Next time you have a package, take a look and try to find any info about how to make a claim on this guarantee. I've never had any of these lights come close to even half of that 7 years.

I second that.

I love CFLs I have then in every light source in my house. But to say they last 7+ years like they say on the marketing material is a joke. I've replaced some within a year (one was burnt out with black burn markings on the housing), some within 2 years and while most of them are still going strong after 3 years.

I enjoy the savings and with the new cool white CFLs, I enjoy the white light. So even with the unreliable lifespans on CFLs I will not go back to old-school incandescents. But take the marketing material on the lifespans with a LARGE grain of salt.

I've made a claim on every one thats broken. Just call the company, they usually don't even want the originals back.
