Plenty of homes -- mine included -- rely primarily on floodlights for overhead lighting. If that's the case, Cree's neatly packaged three-pack of high efficiency BR30-shaped LED light bulbs might tempt you as you pass by it in the Home Depot lighting aisle. The cost? $25, or about $8 per bulb.
That's not the cheapest dimmable LED floodlight that I've seen, but there's still plenty to like here. Aside from the attractive, chrome-rimmed design, the bulbs offer a respectable 655 lumens of brightness, and with a power draw of just 8W each, they're some of the most efficient floodlights money can buy.
How efficient? Let's say you're currently using a bunch of 65W incandescent floodlights to light up your living room. Swap them out for Cree LEDs and you'll enjoy the same brightness and quality of light from an eighth of the energy usage. Spend a year using those Cree bulbs for an average of 3 hours per day, and you'll knock about $7 off your energy bill per bulb. They also promise to last more than two decades, complete with a best-in-class 10-year warranty.
Cree's floodlights work great with dimmer switches, too. In my tests, they dimmed down smoothly to a minimum brightness well below 5 percent on two modern slide dimmers. They were also solid on an older, rotary-style dimmer that wasn't even designed for LEDs, dimming down to about 6 percent with only the faintest trace of a flicker at the bottom setting.
