Cool bulbs - price, temperature and looks
346077
I ordered the three pack of non-dimmable bulbs.  They are brighter than a typical 40W bulb and the base does appear to be slightly shorter than cheaper bulbs I have purchased, but I preferred the color and brightness of these bulbs and the depth of the base didn't cause me any issues.

They look great, there is absolutely no buzzing or humming sound, and if there is a lag between the switch and how long it takes for them to come on, I cannot tell.  All of that makes them a great bulb at a great price, but they also delivered on the one thing I ordered them for - HEAT.

These bulbs are soooo much cooler in temperature than any incandescent or CFL bulb.  After being on for an hour, these bulbs registered 102 degrees F with my infrared thermometer.  My guest bathroom with old incandescent bulbs register 140+ degrees after 10 minutes at the front and over 250 degrees at the sides.  I live in Phoenix and our bathroom gets very warm - this has already been a tremendous help.

I prefer the color temperature (identical to the incandescents we've had for so long)
and these are very robust lights. It would take alot to break these bulbs.

They are a bit heavier than most light bulbs and more than likely wouldn't work in a
delicate light fixture.

These replaced the old 1156 bulbs (very hot) incadecent light bulbs inside motor home. These are a cool white and are brighter. We used them in the kitchen, over dining table and hallway to shower. Left the others with original warm white. Especially in bedroom and over couch for reading.  May replace other with warm Led eventually.  Even changed the outside porch light and really lit outside up. Very good priced. Would definitely purchase again. Two thumbs up.

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.

Goodby halogen bulbs! These are just as bright if not more so and cooler and much longer lasting. Good price too!

These bulbs are actually rated very highly on consumer reports. They have excellent color accuracy, resemble traditional bulbs, very low power usage, they're suitable for damp environments like above showers in bathrooms and in enclosed spaces because of the massive metal heatsink around the base. They'really even dimmable (and look excellent while doing so) You just can't beat them with a price for that. It is worth noting, however that Costco started selling them for only $2.50 each if you buy them in a 10-pack. There's just no reason to buy compact fluorescent bulbs anymore.

Purchased these to replace halogen bulbs in 10-year-old spot lighting fixtures They're a tad cooler than the bulbs they're replacing, though it's not noticeable unless you're comparing. The overall feel is a good, warm-but-not-yellow white. The bulbs fit the track lighting ring, and the retaining clips work to hold these from the back just as they did the halogen bulbs. I'm pleased with the purchase. The price is good, the longevity of these bulbs is supposed to be excellent and the conversion from short-stemmed halogen 3.75 inch diameter bulbs to these LED bulbs has passed unnoticed by the family....

I purchase 12 of these to replace existing 40W incandescent bulbs.  They look great and the color temperature is just right.  I really would have preferred to a 40W equivalent, since the lumens (30W equivalent) are not quite right for my needs.  But I would definitely recommended these.

Very nice bulbs. Not a lot of 2500k LEDs yet.  Most claim 2700k is incandescent-like, but most 2700K LEDs are really not as warm as incandescents, but these 2500k bulbs are just the ticket.

We have a ceiling fan in our living room for our main light source. It had sockets for 4 regular bulbs, but can't take more than two 40 Watt incandescents, and burns those out very quickly. So, we down-graded to 2 x 27 Watt bulbs, and they didn't light the room worth a darn, so I needed an alternative (yes, I realize replacing the fan would be logical, but yeah...) Anyhoo, we tried compact florescent and they just flickered and were just as terrible. We then decided to buy one HitLight LED as a trial, as they are the most sensibly priced LED's I could find, and the reviews were very good. It arrived and we tried it. It is very bright. It is very directional light though, it doesn't disperse well, but still bright. The color is very cool. I know, I bought cool, but I had no idea just how greenish/blue they would be. I'm not saying it's bad, but it takes some getting used to, neon colors are day glow and everything is very vibrant. The one LED bulb mixed with the more yellow/pink incandescents were just not going to work, it was freaky having the varying color light over everything. So, we bought more cool LEDs. Now all the slots are filled with HitLight Cool LEDs, and it's a huge improvement. They have not burned out, nothing is flickering, everything is pretty well lit, I'm  darned happy with these so far. If they last as long as the warranty touts, I'll be a very happy camper. Next time I think I want to try the warm variety for comparison though.

They finally made them! Some fixtures just look wrong with a standard LED, but LED are so much better for their energy usage and for their lower heat output. Even the "warm" LEDs though are usually pretty not-warm. These have the truly warm, yellowish, hue of old incandescent bulbs but with the benefits of LED. Yay!

These bulbs are great.  Have the same color temperature as an Incandescent bulb.  In other words, no LED blue color coming through.  You really can't tell the difference except for the shape.  These bulbs also fit inside frosted lens covers.

Temperature is probably closer to 2200K rather than 2700K.  Gives off a light gold glow and a really nice ambient light.  The lights also look great  while off.  Good vintage look.  I use them in a China Cabinet with a Rheostat.  No buzz or flicker at all.  I also use them in a chandelier and in pendant lights.  If the temperature is right for you, this is a really good bulb.

These are nice little bulbs. They are installed in a "Broan Range Hood". They provide a lot of light. The lenses are interchangeable from spot to flood a cool idea. They don't dim well in the range hood (they flicker). Other than that they are a good value!

These bulbs look great and have a nice warm color light.  They are a bit on the expensive side, but the Lightstory model doesn't have an obnoxiously large base, so it looks just like an incandescent bulb.  I have only been using these bulbs for a few days now, but they are in a high use area.  I'm hoping for high reliability in addition to the energy savings.

Replaced 8 35w bulbs with these, they have a warm color, no hum, very pleased. We tend to leave the lights on more than we should at my house. These will have paid for themselves within a few months... next step, profit?

These arrived today and I wasted no time swapping out the regular incandescent bulbs to give these a try. Here's what I found.

They go on, with full brightness - no delay.
They seem to be a whiter color than the incandescent bulbs they replaced.
They are much cooler in operation; the incandescent bulbs quickly become too hot to touch.
The clear part of the fixture doesn't heat up; the base just gets warm.
But...
They don't seem to be quite as bright as the incandescent bulbs they replaced.
The base makes the lights look a bit like an egg cup on a candle stem in the light fixture I have them in.
The base blocks the light that would come straight down from the incandescent bulbs.

All things considered, I think these are a good replacement for the incandescent bulbs I was using. The plusses outweigh the minuses. They should certainly last a lot longer. Their lower operating temperature is also a safety feature.
