GU10 4-LED 360-Lumen 3500K Warm White Light Bulb (85~265V AC)

Pros: Thins is the best LED light i have ever seen! The spot is really bright and has nice smooth edges. I own some other LED light bulbs, but this one beats all of them.

Cons: The PCB just has contact to the heatsink at the edges - not really much. But the heatsink is open at the side - so there is some ventilation on the PCB...
Also the LED's are noname... but look at the price...

Other: If you want a warm white LED light BUY THIS ONE. It is really, really cheap - even the LEDs cost more if you buy them separately

Pros: Light is reasonably bright. Color of light really is warm white, not bluish. Construction of bulb appears to be of good quality.

Cons: Like all LED bulb, this light is not quite as bright as a normal halogen bulb (though it does come close) The length of the bulb is slightly longer than a normal halogen bulb, meaning that it awkwardly sticks out of my track lighting fixtures about a half inch. :(

Other: Of all the GU10 bulbs on here, this one is the best so far. As a halogen substitute, it comes pretty darn close, and if you're not looking close you probably won't notice the difference. If you want it to blend in it looks a lot less alien than the other 3-LED bulbs. Just be aware that the length difference might make it look a little different when installed next to normal halogen bulbs.

Pros: Very nice, very bright, I compared it to the existent 50W 220 hallogen bulb, the LED is little bit brighter. Clear white light without blue nuances. Much better than sku.13452 and sku.13666.

Cons: The light is more focused than a 50W's hallogen bulb, but if mounted at 2m height, brightness don't fall so much at the ends.

Other: So far I like it. I'll wait how long hey will last, if they sirvive more than 2-3 months I'll buy more units.

Pros: Nearly 40W halogen bulb replacement. Yellow and bright light. Light beam is not narrow, so it can replace without problem any standard halogen.

Cons: MR16 equivalent is not as good as GU-10 one.

Other: 100% recomendable. El resto de leds que he probado siempre me han decepcionado, bien por ser demasiado blancas, bien por ser poco potentes, o bien por tener un haz muy estrecho. Estas son simplemente perfectas.

Pros: Light output seems to be almost on par with a set of standard 35w hallogens. The angle of light output is not as wide as that of standard hallogens, but is not bad compared to the 3 led versions (sku 35287).

Cons: Light color is not very good... it's not really warm white and seems to have a greenish tint that makes light output feel weird. It's definitely not bluish as those 7000k ones, but it's not yellow either (not anything like sku 35287, which produce a clear white light).

Other: Disappointed with the light color, even though the amount of light output is quite ok.

Pros: - Well focused spot(if you like that) - front lense is flat -> easy cleaning - cooling rips and outer ring are good metal, no just cheap plastic with chromium optics like many other products - wide voltage range (does not flicker or change brightness when electrial heaters are turned on) - driver circuit of very good build quality, quality soldering, does not scare an electrician.

Cons: - color not so warm as hoped - color has a light green tint, but acceptable compared to fourescent energy saving lights.

Other: this was my initial purchase to verify the quality, i will no order a bunch more. what a pity that it's not available with E14 socket.

Pros: Nice yellow, warm light from these bulbs. Have replaced four of them from 35w halogen to this ones, I am very satisfied with the replacement. Even warmer light than the halogen bulbs..

Cons: Did not fit very good to the socket on my lamps, had to use some power to get them in, but when they first came in, i (hopefully) don't need to replace them for a while.

Other: Buy this if you want a warm, nice light, I'm very satisfied with the result. They can replace halogen lamps very well. They are just as strong as them

Pros: Nice warm light from these bulbs. I am very satisfied with the choice. Color even warmer light than the halogen bulbs..

Cons: Did not fit very good to the socket on my lamps, had to use some power to get them in, but when they first came in, i (hopefully) don't need to replace them for a while.

Other: Buy this if you want a warm, nice light, I'm very satisfied with the result. They can replace halogen lamps very well. They are just as strong as them!!!!!

Pros: Provide a really nice light. It is quite warm, and makes the yellow light from halogens seem dirty and dingy by comparison. The colours of plants and objects in my kitchen are much brighter and more natural looking under these than under halogens or CFL

Cons: Not really as bright as I hoped. They provide a very bright spot, but overall brightness of my kitchen using just these is not quite as good as when using 35w halogens, but better than with 20w halogens. I have settled for using one 50w halogen with every 3 of these to increase overall brightness.

Other: I have ordered more of these, and can recommend them.

Pros: Very nice bright warm light, good looking lightbulb, energy-aware

Cons: These lights would have as stated a GU-10 connector. They do have a connector being fairly similar, but both lights ordered did not fit into the three GU-10 fixtures I have in my house. I had to file the connectors to fit.

Other: Nice lights. Now I've changed them once so they fit, I'm definitely happy. I am a strong supporter of new developments in LED technology, but I won't order these lights again. I'll just wait for other types ;-)
