1SaleADay has a four-pack of Titan Energy Efficient 7 LED Light Bulbs with 15W incandescent equivalent and a 35,000 hour life span for $9.99 today. The regular price is listed as $79.99 and shipping adds $4.99. Titan’s LED bulbs switch on instantly without a warming up period, and have no toxic mercury. These will last for years, but the wattage is pretty low. I’d use this one as a night light.
