I have noted that the incandescent lamps of today, have much less life than before the incandescent ban took place, and also noted that have a whiter, halogen like color that looks like 2800-3000K. Are the current incandescent lamps being overdriven? Also, I have noted that the current halogen lamps have a lower color temperature than in the past (Similar to 2700K-2900K) and a lamp life similar to incandescents. Is this because they are made from a hard glass instead of quartz in order to lower their price?

I"m don't speak English well, and rely on online translating to write in this site. Please forgive me if my choice of my words looks like offensive, while that isn't my intention.
I only working with the international date format (dd.mm.yyyy).
I lives in Israel, which is a 220-240V, 50hz country.

Indeed, incandescent lamps are driven hotter, in order to boost their efficacy. Given their purchase cost versus the cost of electricity to run them, it make perfectly sense - the cost to replace a lamp is nearly none compare to the electricity cost. Other aspect could be the requirement to print the light output on the package by the largest font (I think it came in 2009, but I'm not exactly sure). That make many people to prefer more energy efficient types. So it ended the habit of underdriving the filaments, so the real median life was longer than the rating - creating a false impression of better quality.
On the other hand (mainly the mains) halogens suffered from too high early failure rate, so lowering the temperature is likely an attempt to compensate for that. The use of hard glass instead of quartz for the bulb could play a role as well.

I've noticed the comparatively short life of modern incandescents vs. the good quality branded ones we used to have, I too had assumed lack of manufacturing quality but this could indeed be the case .. however our GLS bulbs are now labelled "rough service" so I would have thought these would not be overdriven, to improve their shock resistance? Unless it is purely a gimmick to get round the bans ![Cheesy :D](/Smileys/default/cheesy.gif) BG

The bans cover only general home lighting lamps, but they do not apply for the special use lamps. Rough service, long life, oven, signal and so on all are special use lamps, not covered by the legislation. So yes, it is indeed a go-around way over the bans...

Check your voltage! You may need to use higher voltage lamps (if available) to compensate. Utilities are using increased voltages. Even years ago some parts of the country 120 volt bulbs were special order due to high voltage. Texas usually tries to stay around 127 volts which ironically is the nominal voltage for Mexico.

Texas is known for higher voltages and also it on the grid isolated from the rest of the country. This why I hate lamp ban as it don't make any sense ESP for texas

No LED gadgets, spins too slowly. Gotta love preheat and MV. let the lights keep my meter spinning.

Down with lamp bans!

60-watt, 130-volt bulbs are still available at my local Lowe's. I bought a case of 24 recently. I expect them to last longer than normal bulbs since the voltage at my house is right around 120 volts.

I like my lamps thick, my ballasts heavy, and my fixtures tough.

The undredriven lamps have way lower efficacy, so either you would pay more for higher energy consumption (if you want to compensate using higher power - for 7% of voltage difference you would need about one step higher wattage), or you could save quite a lot by using one step lower wattage 120V lamps. How frequently you have to replace the bulbs and how difficult it is, so the extra energy cost won't be way higher than the cost of new bulbs?

I'd be concerned less with cost of lamps but with their continued availability in the future
