The "BR" in BR30 stands for bulging reflector, which simply means that it reflects all the light into a single direction, straight out the top of the bulb. This makes it the ideal bulb shape for overhead track lighting and recessed lighting setups.
With an efficiency rating of 68 lumens per watt, the Cree BR30 LED is a nice upgrade from a 65W incandescent floodlight. Make the switch, and the bulb should pay for itself within a few years, then continue saving you money. The bulb promises to last decades, and comes with a 10-year warranty.
Cree sells its BR30 LED for $20 at Home Depot. That isn't as good of a price point as the $13 Philips SlimStyle BR30, or the Editors' Choice GE Reveal BR30 LED, which costs $18. Read our full reviews to help inform your next trip to the lighting aisle.
