We've got recessed lighting in our bedroom. 8 lights. We've replaced 7 of them in the year we've owned this house. Since we got our rax refund we figured we'd replace them all with these LED units.
They are ridiculously easy to install, last for nearly 4 years of continuous use. They were $35 each on sale for $20. That's about what it'd cost to replace the bulbs over 4 years to say nothing of the power savings.
