I bought one of this Feit Electric 13.5W LED Omni Bulb from a local warehouse Club five months ago, and have been using it in a dimmer-controlled light fixture. It worked so well that recently I went back to purchase another one. Here's what I liked about this LED bulb:
1. It is a true '60W Replacement' LED bulb in that it produces 850 lumens of total light output, exactly the same as that from a 60W incandescent bulb. Many other so-called '60W equivalent' LED bulbs (for example, the EarthLED ZetaLux 2 Pro 7-Watt LED Light Bulb) generate only 400-500 lumens of light output.
2. The LED bulb is nearly an omni-directional light source not quite as good as an incandescent bulb, but close. This makes it suitable for general illumination to light up a whole room. In contrast, the beam from most other LED bulbs is semi directional, concentrated in forward direction. So they are better suited for down-facing recessed lighting.
3. It works well with any TRIAC-controlled light dimming switches (this is the most common type used for incandescent bulbs). Most other LED bulbs are not compatible with dimming. If you accidentally connect one to a dimmer-controlled light fixture, the bulb will start blinking and can potentially be damaged.
I compared the dimming operation of this Feit LED bulb against a 60W incandescent bulb and a PureSpectrum 20W Dimmable CFL, and found the Feit to be superior:
The incandescent turns into a faint red globe at minimum power setting
The CFL is unable to dim all the way down at minimum setting
The Feit LED gives the widest dimming range, while maintaining consistent color temperature.
(See the picture I uploaded to 'Customer Images' for details)
I also measured the power consumption of this LED bulb using the P4460 Kill-A-Watt Electricity Usage Monitor. The meter shows 14W, which is consistent with the '13.5W' rating. Its power factor is very high at PF=0.98, which is a sign of good electrical design. In contrast, many inexpensive LED bulbs I have tested, such as the Lighting EVER 6 Watt LED Bulb, have much lower PF. (Power factor has no direct relation to LED brightness, but a low PF implies more loss in the transmission of electric power)
There is just one potential problem I need to point out: although this LED bulb is called an 'A19', it is actually a bit longer than a typical 60W incandescent A19 bulb. So if your light fixture does not offer enough headroom, this LED bulb might not fit. See the photo I uploaded to 'Customer Images' section for size comparison.
Overall, I found this Feit LED bulb to be a well-designed product suitable for general-purpose illumination. As of this writing, it is priced less than 2x that of a typical 6-7W LED bulb, while generating more than 2x the light output (850 vs. 400 lumens). So I consider it a great value.

I have bought 8 for me, 8 for presents. So far so good. These bulbs are just a little brighter than 60W incandesents, dim at same rate, and not as yellow. I did not buy them all from here. Got them for $9 each, at a wholesale warehouse club. When they ran out I needed one more, bought it here. Dining room lights, just went from 500 watts, to 68. Not directional, but even all around lighting. Only wish the prices were cheaper on here. I prefer these LED lights, to the CFL now, even in non dimming applications. When my CFL lights burn out, and the LED prices come down, I'll replace the CFL ones.
