You can get Decade Bulbs (incandescent) which will last almost ten years with 7 hours a day average use from this company that sells them to the hospitality industry. They burn just a tad less bright than standard bulbs for the given wattages so they’ll last longer.
Get ‘em while you still can!

halogen light bulbs aren’t so expensive. I will probably switch to them before going the LED route....I’m not in favor of banning incand bulbs but it is an old technology and may be time to move on.
