I purchased this bulb off of EarthLed's site when they first came out in April. Cost has dropped significantly since then (nearly $20). Previously my house was filled with 100 watt A-19 bulbs populating 6 inch recessed can downlights. I have approximately 30 of these. I tried a few of these to start and was immediately impressed by the INCREASE in brightness compared to my old 100 watt bulbs! Unlike the CFL's I was also testing these came on instantly which is a huge plus during the winter months. I now have 35 Theta's installed in my house and could not be happier. Wish they were dimmable as well but for the price they cannot be beat.

This is the real deal, a real 60 Watt equivelent. Nice crisp light and bright. The only downside is these are still directional, but if used as a downight, they deliver as promised, strong light, instant on, good color...maybe even better than incandescant...and at a low energy cost.

(posted this for the G7 bulb also):
LED Light Bulb 850 Lumen True 60 Watt Incandescent Replacement Lifetime Guarantee Warm White 9 Watt 180 Degree Illumination No Mercury by G7 Power

Our CFLs at the office has been working great for years but of course they eventually burn out. The same goes with the ones at home. So we wanted to find out more about the newest technology LED bulbs that seem to be showing up in stores a lot more than before. We got both the Thetalux 550 lumen bulb: EarthLED ThetaLux 9-Watt Warm White LED Light Bulb as well as the G7 9W warm LED (850 lumen) to compare it to. I would say the color temperatures they advertise are about right. Thetalux being 2700K and this one at 3000K. Comparing the two side by side, I would say the Theta is a bit warmer (more yellow) then the G7 (more white). As for brightness, it always seems to depend on who you ask. When I see a "whiter" light I think "brighter". But that may not always be the case. Of course, what's pleasing to one person may be horrible to another. I myself prefer the warmer light for home use. So with that said, this G7 bulb is going to the office. Both are going to be used in HALO lighting so the 180 directional light isn't a negative. These Theta bulbs are going right into our kitchen. The rest of our lights are in enclosed fixtures, and they recommend not to put these in them due to the heat build up.

As for construction, I bought six of these G7's and six of the Thetalux's. One of the G7's had a cracked green plastic base and the wire with the green tab was dangling out of the base. I pushed it back in and it seems to work ok. I don't plan on removing the bulb any time soon. The theta's seem to be built a little more solid but of course that would be subjective. The G7's heatsink is a aluminum type shade whereas the theta's are painted white.

In the end, I am quite pleased with both bulbs so my best advice would be to make sure the color temperature is what you want first and foremost. Then go for the lumens, longevity (still have test that one), and then cost in that order. If I were to choose, my future bulbs would probably be the Thetalux's and/or Zetalux 7W warm.

CFLs: pros: cheap, ubiquitous, multiple color temps. cons: ugly spiral, runs hotter, longevity, warm up time

LEDs: pros: instant on (no warm up time), lower watts for the same output, longevity, less hot
cons: expensive, 180 deg directional output, dims if put into enclosed fixture (due to heat buildup)

Hope that helps.

[UPDATE 1/6/12]
Forgot to mention that these bulbs seem to be manufactured by Tess corp, (see tesscop website) a Taiwanese company. Model # T-69002S. So far haven't had any issues yet. Heatsink definitely is hot to the touch after normal operation. Check out the site for more detailed specs.

This is a very good incandescent replacement. Seems very bright, especially when compared to other led bulbs I've seen. You don't have to use a bio-hazard kit to dispose of it when you break one. They last much much longer than CFL's. I accidentally purchased 4 of these lights. I meant to place the 6 watt that is about half the price in my cart. However when they arrived, they were so much brighter than the 6 watt bulbs, I just couldn't send them back. My plan at this time is to purchase one every couple of weeks until I have every bulb in my house replaced with LED's.

I tried several other types of LEd lights, that I returned . I am using led in my kitchen ceiling lights, replacing the 60 watt standard bulbs my contractor put in. With 6 incandescent in one room, the heat was really noticeable. Several other brands LED had lights rated at 3000 kelvin, but the light was way too white for the kitchen, making the food look unappetizing. These bulbs are perfect for the kitchen for general light, rated at 2700 kelvin and casting a very warm light that is nearly indistinguishable from incandescent. At an average of 3 hour a day, they are rated at $1/year to use! I have 2 bulbs over my stove that I got from Lowes, on sale for the same price as these at the time (but no longer), currently almost $30. They are rated at 2900 i believe and are noticeably whiter, but this seems ok for over the stove.
WIthout a doubt I'll buy more of these ( I started with 5) to replace the CFL I have in the house. They also have a 7 watt for $14.99 that put out about 20% less light- probably a good replacement for standard 40watt or rooms with very many light fixtures.

Although pricey, each time I turn them on I know I am saving money and if I forget to turn them off right away it's okay because $$'s are not adding up. I put three of these in a fan light where I most often need extra light. Being an older person, it is nice to know I won't have to keep changing the bulbs. Many conveniences, nice looking & I don't have to worry about how to get rid of them. I would definitely recommend these and buy them again. Fast shipping from Amazon and the best price.

I originally started out buying a 7-watt as a replacement for my lamp. That LED bulb surpassed all my expectations. I ordered two of these bulbs to replace my ceiling lamp's old incandescents, and again, very excellent replacements. The light is a warm "soft white" which is comparable in color the the conventional counterparts. Not an exact color-for-color replacement, but very close. Being instant on and using less wattage usage than a CFL, they are definitely worth the money.

Both the merchant and the product are great. Prompt fulfillment of the order, as I have come to expect from Amazon.com and their partners. The light bulbs are of seeminglt good to excellent quality, although time will tell if they live up to the standards which have been set for LED bulb longivity. The usual constraint with these types of bulbs does apply to these, as well: light beam is directional and does not provide true ambient lighting, which for my purposes is fine. All in all, given the energy savings and the apparent lack of additional radiant heat emissions from the bulb, I am well satisfied and will be purchainsing additional LED bulbs as I continue to replace and upgrade the lighting sources throughout my home. This has a true white color and is pleasantly brighter than expected!

I tried LED lamps a couple of years ago, they were different kind (imports from Hong Kong, bought through e-bay) and boy did they suck... they turned me off of LEDs for a loooong time. They were so weak and lasted only a couple of months. Completely useless.

Now, I decided to try LED lamps one more time. I did not expect much, but as soon as I turned them on, they were very bright and nice color. Perfect. Don't know how long they will last, but so far so good. They easily replaced 75W bulbs, and can almost compete with a 100W bulb in terms of brightness. It is almost as if they are underrated.

Buy them you won't regret it!

Follow up, Sept. 2012:

It has been almost a year since I installed these, in my kitchen and bathroom and they are used all the time, a lot of times in a hot environment (which is a no-no for LEDs), and they are working like champs!

Easily paid for themselves by lower electrical bills within only a couple of months!
Ever month now I save some money, made even better by the fact that before I got them I was over the monthly limit for tier 1 pricing per kW, and now I am within that limit, so the savings are considerable!

Follow up Aug.2013.

All bulbs working strong, giving beautiful light. The other day I checked on our electric meter what is our current power consumption and it was 800w/hr! I had my computer running, our LED TV and the whole place is lit with LED bulbs. Most of those 800 watts was the computer (which has a 900W power supply). It's like getting lighting for free.

Follow up Jun. 2014

Still going strong, same light output, same low electricity bill.

I bought this bulb along with a couple others for comparison, and this is undoubtedly the best combination of size and brightness. It matches the output of my "60 watt equivalent" CFL bulbs, and is conveniently nearly the same size as a 60 watt incandescent bulb. While the light is obviously focused at the front of the bulb, it is able to throw a decent amount light backwards onto a lamp shade if necessary. This bulb certainly isn't cheap, but if it lasts as long as it claims, it will easily pay for itself.
