Rated 4 out of 5Â by sakt Pretty good
This is a pretty good LED bulb. I compared it to a 60 watt incandescent bulb and the brightness is very comparable. The color temperature is similar although this Phillips unit is just a tiny bit more blue/green. It is still very good and I would say better than a CFL
I checked the color spectrum with a blank CDROM and it is smooth like an incandescent whereas a CFL is spiky.
I measured it with a kill-a-watt meter and it stabilizes at 12w after warming up. The power factor is
good at 0.86 compared to 0.60 of a CFL (1.0 is ideal)
The coating on top to help distribute light evenly slightly affects the color temperature so the light is slightly warmer off the top (with the socket down) but it is unnoticeable in a fixture.
Speaking of light distribution. Doing a side by side test, it is indistinguishable from a incandescent for evenness of light. Far better than I expected from the shape
It is heavy. I didn't measure it but it is much heavier than an incandescent.
Startup time to full brightness is very fast. I would say no slower than a comparable incandescent.
Unlike CFLs which take atleast 500mS just to start and then over a minute to reach full brightness.
Audio wise, it is quiet. I have to put my ear against it to hear buzzing and it is quieter than most CFLs
The heatsink does get pretty hot although not quite as hot as an incandescent (I measured 80c after 3 hours)
Checked for flicker with a solar cell and a scope and there was virtually no notable flicker. Less flicker than an incandescent or CFL.
I checked RFI radiation and you can only hear interference if you bring an AM or shortwave radio antenna within 2 feet or hold the base with the electronics. It seems pretty clean overall.
I have yet to test dimming but I am fairly sure it does not redshift like an incandescent. That may be good or bad depending on the look you are trying to achieve.
Life span is TBD.
All and all it is a good performer. Low power usage,good light quality and next to no flicker (Which is good for those with flicker sensitivity)
Wattage is a little higher than stated but it still achieves 70 lumens/watt (note I cannot
measure light output but it is equal to a 60 watt 840 lumen bulb atleast)
I would suggest this to anyone looking to try LEDs. They have come a long way and prices are coming down. I wouldn't hesitate to replace most of the bulbs in the house with this if it were not so expensive.

Rated 5 out of 5Â by MadHatter LED w/No Buzz, Good Look, 2700k, and is dimmable!
I've been looking for this bulb for the past few years. My goal was an LED 60w comparable light bulb that still looked like a light bulb (not some alien monstrosity), was at 2700K (same color as incandescent), is dimmable, and does not buzz.
Buzzing - This LED 60w bulb is the quietest of the A19 variety, barely can hear a buzz whether full on or dimmed and I have great hearing.
Color - Good 2700K color, dims down to a bright white color which is typical among all LED bulbs.
Look - Has a clean look and isn't too big or bulky. I have down sconces and I don't want the bulb hanging outside of the sconce.
Dimmable - I am not using the recommended light switch, just using a Lutron 3-way standard paddle switch and it works great. I tried other recommended switches and saw no difference. Dims LED lights down to about 20%, so not as much as incandescent, but to have no buzz and dim this low, I'm a happy camper.

Rated 5 out of 5Â by Wester Fantastic bulb, great color, no hum, with dimming!
A far superior offering to any CFL and matching traditional incandescent bulbs for light quality . . . this bulb checks every desirable box:
1. It's dimmable!
2. 2700K color!
3. Great light output of 830+ lumens!
4. Fits in every fixture I've tried (great form factor)!
5. Has nice light diffusion (not overly directional like many LED bulbs).
After getting my first one for review, over six months ago, it's still going strong with zero hum and no loss of output or quality.
Our experience was so positive I ordered six more!
I highly recommend this bulb.

Rated 5 out of 5Â by Mike Great CFL replacement bulb! If you want something that looks like an incandescent from behind a lamp shade this is your bulb!
I bought several of these to replace some older cfl lights in my home. The light output is even and the color is almost identical to the other cfl's we own. I tested the wattage with my meter and they do draw the stated wattage. I tend to like the 3000k led lights better (the light is whiter) However, if you want something that looks like an incandescent from behind a lamp shade this is your bulb!
The bulbs do get very warm to the touch. I measured the surface temperature of the white heatsink underneath the glass bulb section. It reaches 168 degrees fahrenheit. The top glass section of the bulb only reaches about 70 degrees fahrenheit. This means that the heatsink is working and the bulb should last a long time.
As a note, these bulbs are not meant for enclosed fixtures. They will slowly cook themselves to death if you put them in an enclosed globe. Also as an electrician myself I can not recommend them for recessed lights. Philips and several other companies make bulbs specifically for recessed fixtures. Use those instead. Your pocket book will thank you:)
This is a great bulb that gives off an even amount of warm light. Its pretty to look at on and off and it will save you a lot of money over its lifespan!!!

Rated 5 out of 5Â by astonman Excellent LED Bulb
I decided to slowly start replacing as many bulbs as possible in my home with LED bulbs. There are a number of brands to choose from but personally I like the look of these Philips bulbs over the other brands. The life expectancy of LED bulbs is based on lab testing. The packaging states that these bulbs should last about 22.8 years based on 3 hours of use per day. I'll be happy with half of that so here is to hoping.
As for the lights themselves, they are heavier than regular bulbs so keep that in mind if you are putting multiples in one fixture. The light looks the same as incandescent bulbs. I can't comment on the dimming since none of the dimmers I have are made for LED bulbs. I'm looking forward to seeing how significant of a saving I will get on my energy bill once I replace enough bulbs.
