Review on Eco-Friendly Daylight Spiral Bulbs 4-Pack: The EcoSmart Alternative by Shawn Price

I wanted a bright fluorescent bulb for the darker winter months and they work well for that purpose. By replacing three conventional 60 watt light bulbs with them, I get more light and use just over 1/3 the electricity. Haven't had them long enough to comment on durability but will change the rating if they turn out to have a much shorter lifespan than advertised.
