Ditto. I just replaced Halogen to Spiral lamps for outdoor lighting in front and back of my house because I got sick and tired of replacing it once every 3 month when it burns out. I made sure that spiral bulb would be able to fire up at -10 degree (in KS, average winter temp is 20 degree some nights can go down to 0 degree). I use 3 of 24 watt (equavalent of 100 watt) in my garage. It was worth it cuz it made my big 3 car garage look brighter. 3 of 75 watt inscadent bulbs can't match that cuz it look dim in garage. I am replacing more indescadent bulbs around my house.
The ONLY drawback for spiral bulbs is that It cannot be used as a flasher for doorbell and telephone. It can damage internal parts of spiral bulbs. I read instruction on Sonic Alert device say "Do not use fluorescent lamp for flasher". I also have astrometric timer (Automatically turns on or off according to time of changing sun rise and sunset, no photoelectric. mounted in switchbox) for front outdoor lighting system. Although the instruction warned me not to use fluorescent bulbs. I use it anyway and it works great. I think it had to do with the standard tube fluorescent lamp require electronic or ballast starting that can damage circuity inside of the timer. The spiral bulbs don't take that much power to fire up.
You need to keep your keen eyes on Kelvin of the bulb. If you see 3000K which is a soft white, 5000K is White, 6500K is bluish white. I hate 6500K. It make my house look like an Apartment (cheap looking Blueish glow
). I made an exchange to 3000K and it look muuch better. At Home Depot, they sell three different Kelvin in package color. You can look at the package showing indicator of which Kelvin bulbs is (It showed "Candle", "Sun", and "Stars" as 3000k, 5000k, 6500k) .. It show Red, Yellow, Blue. While at Lowes, It only show two Kelvin, Soft and Blueish.
Soon in the near future, There will be a LED (Light Emitting Diode) bulb for house. Biggest advantage is that It use 1/2 of electricity than Fluorescent bulbs. Electric bills will be very cheap. It uses White High brightness LED or Luxeon LED (Luxeon is the brightest and is the most expensive for flashlights). Currently, they are trying to match natural light glow of those standard bulbs. Last 10 years or more. Because White LED show somewhat purplish or blueish hue. Nicha LED show whiter which is high quality. IT had many advantages over Indescadent and Fluorescent bulbs. It can be use as flasher (Those who own VP200 have White LED around the camera flashes for ringer. Cool!!!) for deaf and can withstand coldest to hottest tempratures. It can be built to install in tightest spot of the house. Now many new cars currently have White LED for lighting. Currently, They DO sell LED lightbulbs online but it would be too expensive for each, $20 for one equavalent to 40 watt YIKE!!!
The house is getting greener in the future. I bet in the future, they might have Ultrasound Refrigerator and A/C that use very little electricity!! Ultrasound is a ultrahigh fequency sound that act like a friction to molecules in freon to heat up to make it colder to the end. There is refrigerator sold online which use Ultrasound but it is 16cu ft and cost over $1,500 (it looks like an apt ref! and xpensive!!). For A/C, they are working on to improve Ultrasound. So you won't have to worry about power brownout during hot summer.
Maybe once the appliance and bulbs improves. You can run entire house with couple banks of 12v batteries LOL. or use 3 of CI batteries ROFL (It be really nice!!)

The point is to stop eating meat, eggs, and dairy. When the demand for those things goes down, so will the supply; in turn, the pollution. 
. Both home (previous and current) have excellent insulation. It's just the furnace itself. My parent replaced their furnace to Jet type in their 40 years old home that have no insulation at all, their gas bills cut in half.... Same goes for my friends too.
