The whole watt equivalency thing to describe lumens is an astonishing amount of marketing ---smurf-poop---. It's bad but tolerable with the incandescents, but it's near insane with the CFL manufacturers. Those marketing ---uvulas--- completely changed the definition to shove CFL's down ours and the moronic lawmakers throats. --- End quote --- Light bulbs were always marketed to the consumer by wattage. So to tell the consumer that the bulb is equal in light to the 60w incandescent light they've always been while only consuming 13w of power, they had to say JUST THAT. What if CFLs were marketed by lumens instead? 'So, how many 60w lightbulbs is a lumen?" is what everyoen would be asking instead. |

There's no straight corollary between the two values. We've switched to reduced wattage lighting (no thanks to Wal*mart) and the 57w 750 lumens bulb spanks the pants out of the 15w equivalent 60w 980 lumens CFL in terms of brightness. I get that consumers need to know wattages because that's what they're used to. That is a type of mentality that must change. Take a look around at how CFL's are marketed in stores, all that effort to focus on Wattage could have been put forward educating the public about lumens. At least the GE Website makes what the bulb actually replaces a little bit more clear (instead of giving a so-called equivalency rating). Oh well.... I have a sneaky suspicion that in about ten to twenty years, we're going to get a lot of pissed off collectors with faded artwork. |

Very good points made on this thread! One thing since we are talking about characteristics different brands of incandescent even though same watt also have different lumen ratings and also can have a different color cast some give off a orangeish looking light. And some fluorescent also come in different color temps and it can affect how your artwork and even you look under those lights. :D |

Look closely at the fine print on the packaging of these fluorescent lights. You'll see they are not supposed to be put in "enclosed" light fixtures because the electronic "ballast" inside the base of the light bulb will overheat and catch fire! The next time the incandescent light bulb burns out in your refrigerator, try putting one of these fluorescent bulbs in it! It either won't start at all or will be very dim because of the cold temperatures. The same thing in the other direction when your light burns out in your oven. No way can that fluorescent light take 450 degrees of that oven, but a conventional incandescent bulb can. I know several private pilots who use conventional 60 watt incandescent bulbs dangling by a single cord hanging near the instrument panel when the private plane is in the hangar. The reason is that it's a cheap (and safe) heater to keep the instruments from fogging up and from moisture condensing inside during cold weather. |

Incandescent bulbs are looking to be banned from HOUSEHOLD lighting use. That is, anywhere you could use a CFL instead you'll have to. There are situations where a CFL isn't practical and they'll be excempted. Lighting is a major consumer of electricity and if that can be reduced by 75% for house hold lighting that would be a major savings. There will still be uses for incandescent bulbs and they won't be banned outright. |
