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is made by the Secretary of Energy, that still doesn't give entitle the recipient to a free pass to continue using outdated technology.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.

Heat Ratings?

I wish they would do a heat conversion rating on both the bulbs and lamps. Like this lamp is rated for 60 watt conventional bulbs and 100 watt incadescent.

Example I have a ceiling fan and the max rated bulbs for use in it are 60 watt. Its not quite as bright as I would like it to be but I also believe this is for heat reasons that they dont want you to use anything more because of the confined space in the dome.

I would love to replace them with energy efficient ones rated at 100 watt light output which is basically 22 watt energy wise. But does this meet the heat issue? I assume it does because I feel I just put in 22 watt bulbs and would use 22 watts as the heat measurement also but Im not the insurance company.

I would hate to have a freak accident burn down my house and someone say well you used 100 watt bulbs in a rated 60 watt unit. Catch my drift.

Simply put can a 100watt light output safely be put into light fixtures rated for 60 watts.

to answer your question... yes.

The watt rating is the power disapated, a 100W equivalent CFL puts off as much heat as a 23W incandescent.

Thankyou. Looks like Im making a trip to the Depot on the way home tonight.

YMMV, but I put three 18w CFLs in my ceiling fan and it is absolutely blinding whereas the incandescents that came out were dim.

The language is a bit misleading
A 23w CF that is said to be equivalent to a 100w incandescant is not comparing the wattage. What is supposed to be the same is the lumens. That is the amount of visible light given off. Because of differences in the quality of the light I usually go one step up when swapping a CF for an incandescant ... that is I use 75w equiv CF to replace a 60w incandescant, a 100 to replace a 75 etc. I have found a few that actually do live up to their printed ratings, but to my eyes, very few.

An incandescant bulb puts a lot of it's power into infrared light (heat) the CF equivalent does not. So while you can use a 100w incandescant to bake a cake (Easy Bake Oven) you can't cook with the CF equivalent.
