Those curly bulbs really are meant to be turned on and left on. If you leave the room but are coming back 'soon', leave them on. It's the turning off and back on within a few minutes that kills them. They need time to completely cool down and stop their 'activity' within the bulb before turning them on again. This is why they aren't the best in appliances, closets, or motion-sensitive security lights. I've replaced maybe 4 in five/six years.
