I'm a big believer in efficient lighting (LEDs) and am pleased that so many efficient lighting options are available today. So why did I buy these horribly inefficient lightbulbs? Because I like the quality of the light. I use them in my bathroom. I need the soft light they give to use at night before bed. And incandescent bulbs soften and yellow when dimmed, unlike LEDs. Two of these bulbs, semi-dim, provide very good lighting for use just before bedtime. LEDs are not the same. But they are pretty ineffective, especially when dimming. (I use 30-50W to get the level of light I could get from a 5W LED!) However, they only turn on for 10 or 15 minutes a day and our electricity bills are pretty low. So this is the pampering I allow myself!
