1) It cannot be used with a dimmer. Most of my lights are not on dimmer switches anyway, so this wasn't a significant limitation for me.
2) It is somewhat directional, as it directs more light away from the base and somewhat less light to the sides (though it's not as directional as some other LEDs I have tried). One thing to be mindful of is that it may look a little funny in certain scenarios (e.g. when inside of a globe fixture that you want illuminated evenly in all directions). In those types of scenarios, it may be better to go with a light like the Philips 424382 11-Watt A19 LED Household Soft White Light Bulb, Dimmable (which is a light that has neither of these limitations).
With those limitations stated, there are many things I do like about this little light.
1) It puts out a lot of light supposedly equivalent to a 60W light bulb, though I think it looks brighter.
2) It's small and doesn't put out much heat. Many LED bulbs that I purchased are somewhat large and put out lots of heat. This is the smallest light of the 5 types that I bought and actually slightly smaller than a standard incandescent bulb.
3) It's quite efficient at 10.5W, and it has a good Color Rendering Index (rated at 80).
4) It comes on instantly when you turn on the light switch. Half the LEDs that I've purchased have about a 1/2 second delay when you turn on the light switch (which makes me second guess whether I hit the right switch sometimes), but not this one.
5) It has a 6 year warranty. Some other LED brands have much shorter warranties. If I'm paying this much for a light bulb, I want a good warranty.
6) For an LED light, it's pretty reasonably priced at this time.
Some final thoughts: This light bulb has a color temperature rating of 3000K. Incandescent bulbs are around 2700K. So, this light will look a little "whiter" than a standard incandescent bulb. Whether you like or dislike this is largely a matter of preference. I generally like the color.
I have one of these bulbs mounted pointing upward in a lamp fixture that directs light towards the ceiling in a room with tan-colored walls. Items in this room and skin tones look natural to me. I have another bulb mounted pointing downward in a ceiling globe in a room with baby blue walls. I feel like skin tones in this room look a little off to me. That's my subjective opinion though.
I generally like this light and will find uses for it in many fixtures in my house.

I generally think this is an AMAZING price for this product. I would preface it by saying that the color temperature of these lights are 3000K! This looks (in my unprofessional opinion) like 5000K or "daylight" CFLs. I enjoy the 2850K GE Reveal light bulbs and I really like the L Prize 2700K from Philips compared to these 3000K ones, but they are half the price. Be very aware that this is 3000K, I believe 3000K looks really nice in the bathroom / tiled room, but somewhat off putting on its own. I use a combination of the L Prize 2700K and 3000K in my apartment (12 bulbs = 10_3000K 2_2700K) and it really works for me. If you are used to "daylight" CFLs, go for these ASAP as they use a lot less energy and are suitable for rapid on/off.//Not sure if Amazon will delete this, but I paid ~$27 for a 2-pack at HomeDepot [if you delete, please just change to "Other Retailer"] for these, which is by far the cheapest I have seen LED lightbulbs so far. These are NOT rated for closed light fixtures, but I put them in there anyway just to see how fast they would degrade (Hoping to upgrade to newer LEDs as the tech evolves).
Economics:
$14 per bulb @ 10.5 Watt vs 60 Watt. ~ 83% lighting energy savings.
Long rated life and rapid on/off makes this a no-brainer for bathroom application.
Style:
Color Temperature of 3000K much worse than 2850K or 2700K.
Beautiful Spherical Incandescent Style (vs. buglight LED design or nasty coil CFLs)
Performance:
Enclosed Fixture (TBD) So far, glass is barely warm to the touch, seems fine to me. Even if it loses its life in 3 years vs its ridiculous 18 year rated life, I will be perfectly happy. Plus I want the new color changing LED tech from Philips Hue and LIFX in the future anyway.
Cheap ceiling facing IKEA lamps seems to run as cool as my L Prize 2700K bulb, although I have no fears for the L Prize since it is torture test rated by the US Department of Energy.
Brightness:
800 Lumens means nothing to me, I think you need at least 4 of these lights to really brighten up a room (~300 sqft).
Tips for Philips:
Please explain the difference in manufacturing process vs. the L Prize bulbs. Is the only difference color temp & these are made in China (vs. L Prize made in USA)?
4 stars for being the cheapest LEDs around.

There are a lot of different LED bulbs out there and the differences are not captured well by comparing lumens and color temperatures. The key attribute to these is they are a little short and their light comes from a half sphere at the top. This dome is evenly lit but bright enough you still don't want to look at it directly. Relatively little light goes down toward the base while much more goes up. This orientation makes it nice for a fixture pointed at the ceiling as more light spreads through the room and less gets caught up in the lamp shade. Other bulbs send more light to the sides.These bulbs do not dim but are slightly more power efficient than bulbs that do. LED efficiencies are high enough this difference is more a matter of how hot they become than how much money you spend. All are expensive to buy and cheap to power while these are just a bit cooler.
I like the 3000 color temperature. To my eye the tungsten 2700 is a bit long on yellow, 5000 daylight is harsh, 3000 just right. Still, there isn't an awful lot of difference between 2700 and 3000. I remain puzzled by my own reaction to 5000 bulbs despite having confirmed their color balance is indeed similar to natural light coming in a window. I like the natural light and dislike the daylight bulbs, not clear why.
Pick these if you want the light in an even top dome of 180 degrees and don't need dimming.
Honest reviews on Philips 424895 10.5-watt A19 LED Household Bright White Light Bulb
Two of my outdoor 14 watt CFLs burned out. So I replaced them with these Phillips LED bulbs. I was not sure how well they would work, but they ended up working great and have the same brightness as my 14w CFLs.Phillips usually puts accurate information on their lighting products (unlike many other bulb manufacturers). These are 3000k color temperature. Don't confuse color temperature (kelvin) with brightness (lumen). Incandescent bulbs are usually about 2700k, where daylight is 5000-5500k which is a true white light. That spaceship blue light you typically see with LEDs is about 6000k and above. 6000k is not anywhere near a natural light color.
A 60 watt incandescent bulb relates to the brightness (lumen) of a 14w CFL bulb. LED wattage does not have a direct lumen comparison to incandescent or CFL bulbs because the light emitting diodes in LED bulbs come in many different variations. The lumen scale is the proper way to judge brightness between all of them. Here is a chart for comparison:
40 watt incandescent = about 450 lumens
60 watt incandescent = about 800 lumens
75 watt incandescent = about 1,100 lumens
14 watt CFL = about 800 lumens
15 watt CFL = about 830 lumens
This Phillips (424895) 10.5 watt LED bulb = 800 lumens (180 degree light spread)
Phillips (409904) 12.5 watt LED bulb = 800 lumens (330 degree light spread)
Phillips (423244) 10.5 watt L-Prize LED bulb = 940 lumens (330 degree light spread, close to 70 watt incandescent equivalent)
At the time of this writing, a 10.5 watt LED that puts out 800 lumens, like this bulb does, is pretty darn good.
I am not sure if these bulbs are rated for outdoor use, but I have them installed outdoors where my non-outdoor rated compact florescent light (CFL) bulbs were installed. Both the CFLs and this LED light have worked great in our northern temperature ranges of 90 degrees to -3 degrees Fahrenheit. We also have high humidity.
I have these bulbs set up on an automatic timer switch. It leaves the lights on for about 9 hours a night for 7 days a week. Even in the cold, they light-up instantaneously; where the CFLs needed about 15 minutes to get at full brightness. My CFLs lasted for 4 years in this environment, so I hope these LED bulbs will last for 6 to 7 years.
The size of this LED bulb is perfect as an incandescent replacement because it is the same size.
The only negative I have about these bulbs is the narrow spread of light. Because of the long base, it leaves only half of a dome to disperse light to only about a 180 degree angle. I would prefer a 300 degree spread to shed more light around the area. If you want a greater dispersion of light, then get the other kind of Phillips bulbs since they are designed with more rounded domes:
Philips 409904 / 423343 Dimmable AmbientLED 12.5-Watt A19 Light Bulb
Philips 423244 10-Watt 60-Watt L-Prize Award Winning LED Light Bulb
I bought these on sale for about $27 a pair, so I am very happy with them for the price. I really like their performance in my outdoor setting, so I will buy more for the other fixtures.
I would have given it five stars if it had a wider spread of light. 4.5 stars is more appropriate.
