Do a google search to compare prices. GREAT DEAL. I'm a photographer, and I own a couple of these. The light they give out is fantastic. In theory, they last for 20 years. Great for anybody older you don't want getting up on ladders to change light bulbs.
PLEASE let's not turn this thread into a "light bulb policy" debate. This is a website about finding items priced for less, not a political blog

The Philips 12-Watt Ambient LED Soft-White Light Bulb (E)* offers a fully dimmable LED alternative to a standard 60-watt light bulb and provides a soft white light. This bulb is ideal for table lamps and ceiling fixtures. For added safety, the LED contains no lead or mercury. (E)* means this bulb meets Federal minimum efficiency standards.
Brightness: 800 lumens Estimate yearly Energy Cost: $1.45 (Based on 3 hrs/day, 11c/kwh. Costs depend on rates and use.) Life: 22.8 years (Based on 3 hrs/day) Light Appearance: 2700K (Soft White) Energy used: 12 watts Lumens per watt: 71.7 Contains Mercury: No Uses 80% less energy compared to a standard incandescent light bulb Ideal for use in table lamps, floor lamps, ceiling and pendant fixtures Medium Base Dimmable: Yes
who is having problems with heat? i put first geeration ghetto knock off cfl in all celing fans and cans and they work well. do these give off more heat than cfl?

They get hot. So hot you'll burn your skin touching them. These cannot be used in an enclosed fixture or things will melt.
These are SIGNIFICANTLY brighter than "60 watt equiv" CFLs, use less power (and thus put out less heat), and they work with dimmers. In fact, they're so much brighter than the CFLs they replaced, I ended up feeling like I had to buy a dimmer. They won't dim very low though. Maybe 50%-100% or something like that.
One important thing you should know is that these bulbs are not for use within enclosed fixtures. They need to be out in the air so they don't overheat. Being yellow when turned off, they also look a little funny (and you can generally see them in non-enclosed fixtures).
I'm amazed at how fast prices are dropping. 4 months ago these things were selling for $40 each.
1me2ao said: do these give off more heat than cfl?The problem is not that they give off that much more heat than a standard CFL but that they have circuitry inside that is damaged by excess heat. Many of the LED bulbs have a large finned heatsink at the base to disperse heat and keep the circuitry cool. It is the same reason why you should not keep your stereo receiver in an enclosed cabinet without ventilation. Heat kills electronics. This is a good price for these bulbs. Unfortunately, they are regular price at my HD.
$14.97 in connecticut just bought one. Puts out same light level as 13 watt CFLs I swapped it out with for testing. The 13 watt CFLs are also 60W equiv. Also tried it in my dining room light with dimmer and unlike dimmable CFLs, there was no loud buzzing or flashing at lowest voltage level, so when these come down to $2-5/ea I'll probably buy more.

Mantua NJ store outside Philly has them for this price for a while due to a local subsidy. Good bulbs. Philips has regular $10 off $30 rebates on these so you have to buy three at this price. Not sure if a new rebate is up yet. Last one ended 12/31/11. This version is coming down in price ahead of the 75 watt version that is coming out. If you can find them, they are $40 which is what these ones first cost.
Last time I did back-of envelope calculation of cost of owning these vs. CFL (purchase price + wattage price for same lumens over the projected claimed life of the bulb) it did not come out cost effective (even at $9.97 clearance price at costco). Has anyone else done this calculation?
Spacey said: One important thing you should know is that these bulbs are not for use within enclosed fixtures. They need to be out in the air so they don't overheat.Good to know. Is that true of all LED bulbs? I would like to put some in a high ceiling fan, which encloses the bulb area in a glass bowel.
CFLs tend to be cheaper than LEDs when you factor in cost and duration, but LEDs are getting closer. This particular LED is about as close to an incandescent in color, dimmability, and instant on as you'll find. This isn't the case with CFLs. Kind of like a low-end car vs. a BMW. You get what you pay for. In this case, the BMW has gotten a lot cheaper.
The main reason I'm using LEDs are because they are instant-on (the kitchen was like 50% brightness for the first 30 seconds in the winter when I had CFLs in there) and because they are dimmable (nice for the living room). I've also had a high failure rate of CFLs. Perhaps this is because of all the on/off switching that happens in places like bathrooms and hallways. CFLs don't like to be switched on and off a lot, but LEDs don't mind.
I also went ahead and put LEDs in a few of the most heavily used lights to save on energy. I don't expect the energy savings to ever pay for the cost of the bulb, but figured I can afford a little cost to be greener on the lights that are on for many hours every day.
Other LED bulbs may be OK in enclosed fixtures, but you'd have to look at the info for that specific bulb. LEDs don't like to be hot. Lower wattage means less heat, but even 9-12 watt bulbs are too hot to touch. Every LED bulb I've seen has extensive heat-sinks to try to move that heat away from the LED. Many don't say one way or the other, so they're probably fine. However, the bulb that this post is about is a higher wattage than most (and brigher than most) and makes it pretty clear with warnings (even on the bulb itself) to use it only in an open fixture.
Oh, and to the person who said these hum when dimmed, it must depend on the specific dimmer. I like these bulbs specifically because they don't hum. I put in some GE LED bulbs and they hummed badly, so I went back to these ambientled bulbs.
has anone heard when SWITCH brand leds will be available for sale? They look nice,but expensive,but more importantly,when another major player in leds comes around,i am hoping to see a price war competition.

Versus CFL? No, you're probably not going to see much of a difference. The comparisons are usually done to the 60 watt incandescent.

Versus CFL? No, you're probably not going to see much of a difference. The comparisons are usually done to the 60 watt incandescent. For CFL, it comes down to light quality for me, I hate them. I have 6 of these LED bulbs and love them and the number of hours is huge! The dimming capability is also much better.
just picked up 4 at my watertown, MA location online said 19 but didn't see many more. Had a NStar promo decal. I wish they would discount other models not just the 12.5w(60w) ones.
Instant on is nice compared to CFL but price doesn't make me wanna switch my whole house to LED
Still waiting on the Switch liquid cooled LEDs to get out of testing and into mainstream. Supposed to be in some hotels and commercial areas now so they can build feedback and QC. I just wish I knew which one so I could do a Foldgers switch on their bulbs. ha ha
This is good news if they are clearing these out. The newer versions that won the L-prize are 900 lumens instead of 800, produce better light (93 CRI instead of 80) and are less than 10 watts (instead of 12 watts). They were mentioned to be released early this year.
light emitting diodes when powered by any "high" (we're talking around 1A or less) source produce very high heat through its base. in general, waste energy from incandescent bulbs are in the form of IR heat that you feel/sense. With LEDs heat is conducted through the circuitry of the system, and needs to be mitigated using heat sinks or some other method.
low power yellow LEDs don't produce too much heat, and natural convection using simple heat sinking (generall found in the natural design of the product) can often be enough to have satisfactory results.
If you're in Rhode Island or Massachusetts and you have National Grid, NSTAR, Cape Light, Western Massachusetts Electric, or Unitil, you can buy these bulbs for $15 with free shipping from http://www.energyfederation.org/estarlights/default.php/cPath/42.... You're limited to 12 light bulbs, 12 light fixtures, and 2 energy-saving surge protectors per program year.
From popular mechanics article: LEDs are cooler. When you're running fans or an air conditioner this summer, having burning-hot incandescent bulbs just makes it harder to manage the heat. LEDs run much cooler than incandescent bulbs and significantly cooler than CFLs.
