Philips SlimStyle 60W Replacement LED bulb (10.5 watt, Soft White)

For a less three-dimensional spin on home lighting, check out the flattened-out Philips SlimStyle, which looks like a light bulb in silhouette only. Why flatten things out? Heat dispersion -- with the SlimStyle's unique design, Philips was able to distribute the diodes along the upper perimeter of the bulb, away from the heat at the base. That eliminated the need for bulky heat sinks and made it possible for Philips to sell the SlimStyle for less than $9. One caveat though: unlike the standard Philips LED, the SlimStyle gets a bit buzzy when used with a dimmer.

The Good The oddly-shaped Philips SlimStyle is a value-priced LED that serves as a respectable incandescent replacement. The flat design helps it manage heat better than other LEDs.
The Bad The SlimStyle gives off an annoying buzz if you use it with a dimmer switch. Also, the three-year warranty isn't as good as the 10 years you get from the Cree LED, which costs just a dollar more.
The Bottom Line For such a flat bulb, the SlimStyle is surprisingly well-rounded, making for a decent value at its price point.
Part Number: 433227


At $9 each (or lower, if you live in a region that offers instant rebates for Energy Star-certified light bulbs), the Philips SlimStyle offers plenty of light bulb bang for your buck. You won't have any problems with its brightness or color temperature, and if you're switching over from incandescents, you certainly won't be complaining when your next power bill arrives.
That said, for a dollar more, the Cree 60W Replacement LED offers an uptick in efficiency, along with a 10-year warranty that's more than three times what you'll get for the SlimStyle. And for ultimate value, the $5 Ledare LEDs at Ikea are awfully tough to beat -- although their diminished brightness and lack of a warranty stop me from recommending them outright.
If you're looking for a bulb to use with a dimmer switch, you'll want to look elsewhere, as the SlimStyle tends to buzz quite a bit more than other LEDs whenever you dim down to 50 percent or lower. On the other hand, for enclosed fixtures -- globes, sconces, and so on -- the SlimStyle seems to be an ideal option.

Just another Cree LED BR30 @10 US Dollars

Cree's closing the gap with a new-and-improved second-gen model that sells for a much more reasonable $10 per bulb -- less than any of those other competitors. It still lags somewhat in terms of color quality, dimming performance, and heat management, but offers satisfying performance for general household lighting needs. If you've been waiting to upgrade a whole home's worth of floodlights, it's your most affordable big-name option, and a good choice, overall.

Green Creative BR30 Cloud LED; The Hollowed out Floodlight

The Green Creative BR30 Cloud LED looks like something straight out of Star Trek, but the futuristic-looking build serves a purpose. Floating the LEDs up above the body of the bulb reduces the weight of the bulb, and also helps it manage heat better, which, as anybody who's ever owned a laptop that was prone to overheating can attest, is a good thing.

GE 16W LED 100W Replacement LED

Rising efficiency standards spelled the end of the 100W incandescent light bulb. Thankfully, your options have been steadily expanding ever since, with a full crop of new LEDs promising that same level of brightness from a substantially smaller power draw. Of these new bulbs, the GE 100W Replacement LED is one of the best.
The bulb's most impressive spec is that it only consumes 16 watts of electricity, efficient enough to put out 100 lumens per watt. That ties it with Utilitech's bulb, making the two of them the most efficient 100W replacements we tested. Nothing else was able to get above 90 lumens per watt.
GE backs its longevity claims up with a 10-year warranty, the same warranty that Cree offers for its bulbs. That's as long a warranty as you'll find on a brand-name light bulb, and an exceptional deal for skeptics who aren't sold on LED value just yet.
