Rated 5.0 out of 5.0 by tsymyn First of the really acceptable LED bulbs
These are the fourth kind of LED GU10 equivalent bulbs we've tried, and the first we've stuck with. The color is very close to a normal halogen. We switched from Reveal halogen bulbs to these. The color is not as warm, but it's completely acceptable. They truly are instant on (most of the competitors are not) and are probably really closer in brightness to a 50W GU10 than the 20W they claim to replace. We don't notice the room being dim at all with these. And the real plus is that they've lowered the power usage of our eight-light track from 400W to 48W, with a comparable reduction in heat, which is alone worth the price as many days in a row as it's been over 100 here. We're very satisfied and haven't hesitated to try this brand for other bulbs, too.

Rated 5.0 out of 5.0 by Ingram1225 Very Bright!
It is true, they are brighter than my 50w halogen lights. For my fixture, it would have been nice if there was just one led light facing backwards but it's a non factor. As you can see in the picture, the LED light is on the right, and casts a cleaner brighter light than the halogen lamp. Truly impressive.

Rated 5.0 out of 5.0 by EUPHOR1C Surprised at the brightness!
The only negative I can come up with about this bulb is the cost, but if these things last as long as claimed then it is well worth it. Let alone the pain it can sometimes be removing GU10 bulbs. I am really surprised at the amount of light these things put out. When compared to the stock halogens that came with my fixture these are SIGNIFICANTLY brighter. It is night and day when comparing the brightness of these. I also love that they are not white fluorescent in color. Still gives off the color that a halogen would.

Rated 5.0 out of 5.0 by Lion Great for lighting art work
Fits the fixtures better than the incandescent lamps with a white light instead of the yellowish and remains cool

Rated 3.0 out of 5.0 by IGfoobar Bright but noisy.
I installed four of these bulbs in a track light fixture in my kitchen. The light output is very bright but not as "warm" as a halogen. Unfortunately there is an audible hum from these bulbs. It is not terribly loud but it is there.

Rated 4.0 out of 5.0 by InTheDark Good LED for GU10 sockets
The only drawback to this LED is the lack of a diffuser.
The light is very bright and hard on the eyes if looked
at directly. Also note that the color temperature is
hotter than the old incandescent lights, with a yellowish
cast rather than the somewhat cooler orange glow we've all
known for years.
But it provides plenty of light with just 6 watts, so works
fine in ceiling tracks/sockets, or for indirect lighting. Given
its expected lifetime, I'd recommend this for any situation
where it could be used if glare is not a problem.

These lights rock! I was skeptical at first, due to cost and questioning whether the amount of light produced would be enough; however, I am more than satisfied with the light produced and instead of using 400 watts, i am now using 48 watts. Lastly, these lights give off almost no heat, unlike the halogen bulbs they replaced. Buy these!!!!

Rated 4.0 out of 5.0 by wolfwizard Decent replacement for 50 watt halogen, but doesn't dim very well
I tried one of these in my 6-bulb track light that is over our dining room table. The existing GU10s are mostly Philips 50 watt FL25 (25 degree flood) bulbs. When dining at the table, the area gets quite warm from the halogens. So besides the energy savings, getting rid of the heat is another reason to go LED.
The light output is quite comparable to the halogens. The color temp also seems to match the halogens fairly well. Though if one holds a white plate up to each, the halogens are definitely a bit yellower than the LED.
A previous reviewer noted that there is more glare from these bulbs than the halogens, and it is true. It is because the LED emitters are very close to the edge of the bulb, as opposed to being recessed in a reflector. Some MR16 bulbs use a single LED and recess it like a halogen bulb. However the trade off is that a single LED may not be bright enough for many applications.
As far as dimming goes, this bulb does dim - some. But no where near down to the 'mere glow' level that one can get with incandescents. Note that I am using a regular Lutron Diva dimmer - not a LED/CFL specific one. So it may be possible they would dim better with a more LED-friendly dimmer.
