Rated 5.0 out of 5.0 by The2000Man Phillips got it right!
I love these bulbs. They come on almost instantly (about 1/2 second warm up) with a pleasing white light that is as bright as a standard 75 watt bulb. They are quite expensive so I'm only using them in areas where I need instant on lights. Here's a suggestion: If you have fixtures with multiple lights, just replace one bulb with the Phillips LED. You will notice an immediate difference & you can replace the others as your budget allows.
Don't be put off by the odd appearance of this bulb. Once it is on it looks like any other bulb.
I have not tried this bulb in a dimming circuit, but Phillips claims it is dimmable.
Consumer Reports rated this bulb a 99 out of a possible 100 & I have to agree with that rating.

Rated 5.0 out of 5.0 by momendo High Power LED
I've been waiting for a high power LED light bulb for some time. As far as I can tell right now, this is the highest power consumer A21 LED light bulb in the US. There's a 60W A19 version of this bulb which appears to have a shorter heatsink. This bulb comes in a hard shell blister pack. There's no instructions save what's on the box. It's dimmable. It turns on almost instantly reaching full brightness with what appears to be under half a second. It does hum if you put your ear within six inches. It's imperceptible beyond that distance. After a few minutes, the bulb is hot to the touch. It's hot like a CFL especially at the metal base heatsink. The three domes are yellow, but when you turn it on, it glows warm yellow white (2700K) The main selling point to me is the brightness (1100 lumens at 17W). My Belkin power meter seems to back up that wattage at 17-20W. It claims 70W equivalent incandescent performance and I believe it. I used this to replace a 27W CFL and this bulb is just shy of the brightness that bulb puts out. The three yellow domes make this bulb stand out visually. If you place the bulb in an enclosure that is transparent, you will see the three dome seams. If that bothers you, you should place it in frosted glass or cover it so you don't see the spacing between the domes. The shape is bulb like. It disperses light just like a regular bulb. Though the center-top of the bulb doesn't emit as much light. In a top-down setting, your bulb should be recessed in a metal enclosure to get reflectivity in the downward position or use a flood LED lamp instead. I recommend this bulb to early adopters of technology and green minded people. Since this bulb lasts a long time, it's also good for bulb replacements that are hard to reach. Pluses: This bulb delivers on the brightness without any of the downsides of CFL. There's no toxic mercury, hardly any start up lag to full brightness, dimmable, pleasing color temperature for homes, quiet, not too hot, lower power at 17W and reportedly lasts 25 years. Minuses: The price is $39.97 at this time of writing. The odd looking heatsink and shape of the three domes. It doesn't emit as much light at the top of the bulb.
Get the 17W bulb as the 12.5W bulb is the same price on homedepot.com

Rated 5.0 out of 5.0 by Madscientist42 Expensive, but VERY worth what you're paying for them...
It's hard to add to what others have said about these bulbs.
Unlike LEDs of the past these and the others in Home Depot these days actually DO replace the claimed equivalent Incandescents (sometimes actually rivalling them)- these literally are drop-in replacements for a 75-watt down to color rendering, etc.
Many will point to the CFL's in the stores and elsewhere and claim they can get a "comparable" bulb for 1/4th the price of these. They'd be lying to themselves and to the people that they tell this to.
These bulbs are as efficient or moreso than CFLs.
These bulbs produce the same color spectrum of an incandesent. (If you're looking for bright white or daylight, there's other bulbs in the area or online from other vendors that'll give you the same performance with the differing color spectrum)
These bulbs are typically less fragile in most ways when compared to CFLs. In the case of these, the lenses are plastic and there's nothing that vibration will do the parts.
These bulbs are truly instant on.
These bulbs are at least somewhat more compatible with dimmers and the like than compared to CFLs
These bulbs don't have a ballast and typically have less circuitry in them than a CFL- so they'll last longer.
They light even when in freezing cold conditions.
These bulbs don't have mercury in them.
I've been replacing everything (CFL and Incandesent) with these when the bulbs go out (and in the cases of CFL's, I'm typically not waiting that long...)- and they tend to be a better result than the CFLs have been because in many cases, you can "cheat" and jam more "equivalent" light (i.e. Putting a 60w or 75w into a 40w...) into a fixture than the fixture was designed with Incandesents in mind with and it acts like the Incandesent otherwise, unlike the CFL answers.

Rated 5.0 out of 5.0 by MFlouisville This light bulb is excellent.
The bulb casts a warm white light very similar to a traditional 75 incandescent bulb. The brightness of the bulb, its color rendering and its beam spread are all pretty much identical to a traditional bulb. This bulb works great in a shaded lamp. The bulb has a very slight delay of maybe half a second before coming on to full brightness. The bulb has a very slight humming sound that is only noticeable if your ear is next to it. I have not yet tried the bulb on a dimmer, but according to the packaging, it is fully dimmable. Power usage according to my KILL A WATT meter is about 17 watts, which is the same as advertised. The bulb looks to be very well made. I highly recommend this product.

Rated 5.0 out of 5.0 by Dave Nice light, similar to incandescent but 1/3 the watts
I have these bulbs as well as the slightly smaller version in my home. The light is very nice, I mean the quality of the light bulb and the quality of the light that is emitted. It is also my unscientific opinion that it puts out more light than a 75W bulb...not equivalent to 100W but probably 80+. Same goes for the 12 watt version of this light which claims to be comparable to a 60W incandescent, seems closer to 75w to me.
They also work with dimmers. They are bright yellow when not lit so are difficult to use in a clear or open fixture because the color does draw attention. Hey Philips and Cree! A 3 way version of this would be nice. Great bulb, not so great price but I still bought a ton of 'em.

Rated 5.0 out of 5.0 by strat Good for table lights
Replaced a few 60W table light incandescent bulbs with this LED bulb. The light output is comparable to the legacy 60W bulb or a little brighter and emulates the legacy bulb's light dispersion pattern (e.g. light washes down on the table's surface).
But as some people have cited the bulb looks like it came out of a science fiction movie, thus you will only want to use this bulb where it isn't in plain view when off. On the other hand some may like the science fiction look...
As of today this is the best alternative to a traditional incandescent bulb for table and reading lamps.

Rated 5.0 out of 5.0 by Sammy Beautiful light and smooth dimming
As a former Theatre Lighting Design I'm still picky about lighting around the house. After watching numerous 3 way incandescent bulbs die quickly, I decided I wanted dimmable LEDs. After some research, I settled on these bulbs.
The light is a great temperature and the fading is smooth and flicker free. I use them in a single switch lamp, with the Lutron table top dimmers.
My only beef with these, and leds in general, is the low cutoff point. The lowest dimming light level is still brighter than incandescent but is still nice and dim. Just a note. On the whole, great purchase.

Rated 5.0 out of 5.0 by CRAZ8 Great light, but with some startup noise
I just purchased one of these bulbs.
The light from the bulb is great, with the right shade on the light, there is no way to tell that this is an LED bulb from any distance. My previous LED bulbs have all been way too blue.
However, when you're up close to this bulb, for the first 15-30 minutes of operation, the bulb hums noticeably. Since I'm using this on a nightstand, I'm usually in a quiet place, and the lamp is within 2 feet of my ear, so I can hear it for the first 15 minutes or so.
If Philips use this technology for indoor flood lights, I'll be buying a bunch of them!
