These are advertised at EarthLED ZetaLux 2.
I received a "TESS" bulb.
After sending an inquiry, I was told by EarthLED that they are
the US distributor for zetalux and that Tess is the same product with a different label on it.

All fine but really, they should advertise it here as TESS, not zetalux OR at the very least state here that
the product are equivalent/identical and that you may receive one or the other.

Given the cheaper price (all relative, not sooo cheap when you factor in shipping costs), I decided to
keep the bulb.

The product itself:
Light OK. A little dim (most LEDs are).
light color: green/blueish, very cold (no matter what they claim the color temp to be).
Fine by itself in a corner of the room but make sure there are no other incandescent, warm CFL
or truly warm LED lights in the same room or else it feels like an ice cube!

I purchased 3 LED lights to test.
+ The one reviewed here
+ Dimmable E26 A60 Standard Household Base 50 Watt Incandescent Light Bulb Replacement with a 6 Watt LED, Warm White, 1012ww
+ Pharox 300 Dimmable

The E26 one and the Tess were equivalent. I would not purchase them again.
The Pharox while a few bucks more IS WELL WORTH THE EXTRA COST!!!
It is warm, nice, feels brigher and works well enough with a dimmer.

This is my first purchase of an LED light bulb. I was one of the first to purchase the CFLs several years ago and the CFLs were costly just like this LED light bulb.

The CFLs have problems with their life span and if this LED bulb give out, i will come back and update this review.

One problem with this LED bulb is the heat sink. the heat sink restricts the light from shining behind the bulb. as a result, in applications where the bulb would be facing up, like in a hall way light, there is very little light shining down from the bulb and the hall way will seem to be dimly lit. Therefore, this limitation reduces the areas that the bulb can be used.

Brightness of the bulb is pretty good. As compared to a 60 watt incandescent ceiling fan bulb. This LED light does a fairly good job. Due to the heat sink, again, the spread of light is reduced and that decreases the reflective light in the room. This LED bulb compared to a CFL, the problems is the same. But as compared to the CFL, there is no warm up time that is needed.

Light Color of the LED is more white than the incandescent bulb which appears to have a yellowish tint to it. )I am color blind so I could be way off).

This LED bulb is supposed to last 3 times longer than a CFL.

So here is some math at the time of this writing.

The LED Bulb 9.83
3 CFL 60 watt equ. @ 1.18 per bulb 3.54

Cost to operate LED/yr 1.10
Cost to operate CFL/yr 2.56

Estimated 17 year life cost
LED 18.70
CFL 43.52

TOTAL COST
LED 28.53
CFL 47.06

Savings LED 18.53

As you can tell by these numbers, at the current cost of the LED bulbs, it will take several years to get the LED light bulb to pay for itself.

As long as you use this as a downlight you can easily achieve light output levels of a 40 watt incandescent. Best of all the color of the light is very warm and pleasing unlike many other LEDs I have tried. At just a bit over $9, this may be the best value in the LED market today.

I purchased this EarthLED bulb and was pleasantly surprised with the amount of light output for the power consumed. Also tried some other lamps from Home depot but they did not produce nearly the same amount of light in my situation a standard recessed downlight.

I bought this light as an experiment. I was under the impression that LEDs gave bright but harsh light. As EarthLED is billed as "Warm White" it seemed the best candidate for a trial. And the price was right.

From my limited experience, this EarthLED is, in fact, warm white. It is not harsh on the eyes. The hue of it is pretty good. I tried it in several fixtures. Given its construction, it does not cast light below its flare (or fluting base, or whatever you'd like to call it). So, I put this bulb in the fixture above my bathroom mirror, which is in an overhead position.

It is instantly bright and the color is fine. It is not soft like a conventional incandescent, but it is (to my eye) a nicer, sharper tone than the yellow of some soft CFL bulbs. If you prioritize efficiency over slight, variable shades of what "warm" should look like in your light bulbs, the EarthLED is a good choice.

I compared the ZetaLux with a 60 watt halogen bulb in side-by-side pendants. Although the ZetaLux was not as bright overall as the halogen (after all, they only claim it to be a 40 W equivalent), the brightness on the work surface, a kitchen counter, was comparable. Colorwise, the ZetaLux was slightly redder, but the difference would be unlikely to be noticed unless the bulbs were compared side-by-side, and the color was pleasing to me. I like the quality of the light, instant on, and instant full brightness much more than compact fluorescents.

This is a good choice for things like pendants, gooseneck desk lamps, and possibly ceiling canisters --- anywhere a 40-60 Watt standard incandescent bulb would be used where only 180 degree lighting is desired. It will be interesting to see what its lifespan is in a semi-enclosed area like a pendant; heat is the killer of lifespan for LEDs, which is why these types of lights generally have heat dissipation fins. In any case, at less than $10/bulb they should be much more cost-effective than CFLs in applications where the light is frequently turned on and off or where the bulb is mounted pointed down. In my experience, CFLs don't last much longer than incandescents in those situations.
