I have been replacing burned out bulbs (mostly CFL's) with LED bulbs as I'm able. I've had success with most, and failure with some cheap Walmart alternatives.
For most applications I've used 40-watt equivalents. For the 3 aforementioned Cree bulbs, I put them in our half bath. For our needs they put out more than sufficient light. Had I used 60-watt equivalent in the half bath, it would have been way too much light.
Next on my bulb replacement list will be the 4 halogen bulbs in our bedroom ceiling fan. I will use Cree's 60-watt daylight equivalent for that application. Afterward I'll replace the 5 CFL's over our dining table, also with 60-watt equivalent (but not daylight).
My driveway and front porch each have 40-watt equivalent LED lights. Those have worked perfectly over the last several months.
About 3 or 4 years ago I installed 5 each 60-watt equivalent LED "flood" lights in our kitchen (hard to reach). Those have worked way beyond my expectations, although they were $50 a pop at the time of purchase. But they have worked as promised and they put out excellent light.
What I will not do is buy another CFL. I've come to hate those things as they are inconsistent and undependable. They rarely last more than a few months, they are slow to warm up in cold weather, and the light output is often unpleasant and/or inconsistent from bulb to bulb. Not to mention that they're ugly.
Scuzzy; I refuse to mention it.
