LEDs are just an application of solid state physics and are not that new to us. We have seen these lights in radios, cell phones etc already. Only the improvisation to use these as dedicated light sources to replace incandescent bulbs is revolutionary and rather new.

Philips SlimStyle BR30 65W Replacement LED Bulb (9.5 watt)
Philips raised plenty of eyebrows when it introduced the original SlimStyle LED earlier this year. Months later, the company followed suit by announcing an LED floodlight that borrowed both the SlimStyle's name and its flattened-out approach to bulb design.
The GoodThe Philips SlimStyle BR30 is one of the most affordable LED floodlights you'll find, making it a great value for simple recessed lighting setups.
The Bad Like its predecessor, the SlimStyle flickers and buzzes when used with a dimmer switch. It also isn't as bright or as efficient as some of its competitors.
The Bottom LineThe price is right for this unique light, but as there are other options that offer notably better performance for a few dollars more, you may want to shop around.
Part Number: 415281
The odd design aside, the Philips SlimStyle BR30 LED looks like an appealing value pick. At a price of $13, it's priced at least a few dollars below any of the major competitors. Like its little sibling, it isn't a good choice for anyone using dimmer switches, and I wish it were at least slightly more efficient -- but flaws like these are easier to forgive when you're saving money.
Still, given that you'll potentially be living with this purchase for the next few decades, I think it makes sense to consider spending the extra cash on a bulb that offers a little more. The $18 GE Reveal BR30 LED seems like an especially good deal to me with its impressive performance on dimmers, significantly longer warranty, and dramatically enhanced color rendering capabilities.
With LED prices continuing to fall, we're seeing more and more bulbs selling for $10 or less. One of the latest options is the Osram 60W Replacement Ultra LED, which rings in just a few cents shy of that 10-buck benchmark. Thankfully, this lower price plateau doesn't represent a dip in quality, at least not with Osram. With well over 800 lumens of light output from a power draw of just 8.5 watts, it's one of the most efficient 60W replacement LEDs we've tested, and it performed well during our dimming tests, too. That makes it an easy bulb to recommend, even among an increasingly crowded field of worthwhile competitors.
The frosted bulbs on today's LEDs aren't just there for softer light -- they also hide the unsightly hardware inside. But what if you're a fan of the exposed bulb aesthetic, and looking for a worthy replacement for those translucent incandescents lining your bathroom mirror?
Philips thinks it has just the thing with its new Clear LED, a 40W replacement bulb which the Dutch company promises will mimic the "elegant shape and sparkling light" of traditional incandescents. With its A60 shape, clear glass bulb, and inconspicuous heat sinks, this LED is designed to strike a more familiar tone with consumers than its often irregular-looking competition.
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.
