Lamps are brighter than any other lamp I have ever used. I have them in every lamp. They are economical, energy efficient and durable. I'll admit they aren't as cheap as other light bulbs you can buy, but they are way better than anything else you can buy. The lifespan you get from them makes up for the cost of the cheap lightbulbs you used. Once you start using them, you'll wonder why you didn't buy them sooner :) Smooth delivery and gentle handling!
