GU10 500-550LM 3000K 16-SMD LED Warm White Light Bulb (6.4W/AC220V)

Pros: - Illumination is much better comparing to 50W halogen bulbs at power consumption which is eight times lower - The price - bulbs with similar parameters cost at least three times as much here in Slovakia

Cons: - Even if the switch is turned off, they still glow weakly for some reason - LEDs are in no way protected from the surrounding environment. Is therefore questionable, what will their operating life be

Other: I bought five of them for a try an I am going to order another ten, to replace all 50W halogen lamps at home

Pros: Very bright. Warm light. Low energy.

Cons: Had a little difficulty fitting the bulb into my recess lighting as the clip wouldn't seat properly to hold the bulb in place. Managed to push the bulb up into the recess and it stayed in without the clip.

Other: Worth buying if you want a bright room.

Pros: - Powerful and warm light. - Very wide angle. - Perfect airflow when using the bulbs in fitted lamps, so the bulb gets hot, but nothing unacceptable. - Led board makes good contact with the heatsink and it's fixed with a metal clamp so it doesn't move.

Cons: - It's a pity this one doesn't come with a small protective glass. - The bulb gets hot, but the good airflow makes the heat nothing unacceptable.

Other: I hope they last a long time because I'm going to order ten more of these to replace all my home's hallogen bulbs. ;)

Pros: Very bright, illuminated by a beam wide open, I think he can overcome a 50W dichroic easily with a tenth of consumption.

Cons: Light is yellow, is more than warm. for some applications can be perfect but the color in a room with warm colors would remain too yellowish.termination is not perfect because the LEDs are unprotected, with no glass to protect them from outside contact.Produces a flickering effect that is bothersome to the eye, do not recommend using it in places of work long hours for the fatigue to the eye blink

Other: I recommend it, I will buy it

Pros: Perfect replacement for 35 watt halogens. Illumination is more between 35-50 watt comperard to halogens. Light is warm but a birt on the white side. Good build quality. Good price.

Cons: The bulb gets hot, which means there is some energy leak into heat. I would assume that these would be consuming more energy than the indicated 5.5watt in the product details. Because the heat produced is somewhat equivalent of 10watts (or more) compared to other heat/light sources.

Other: Good product

Pros: Low price Low power consumption Good light temperature for a LED Long lasting (hopefully)

Cons: The diodes are not protected in any way - should be mounted in a protective fitting or away from prying fingers. Stays relatively cold while on.

Other: A very good product that I can recommend, given that you do not want a spotlight in the true sense of the word.

Pros: - Výkonný a teplé světlo. - Velmi široký úhel. - Ideální proudění vzduchu při použití žárovky v vybavených lamp, takže žárovka zahřeje, ale nic nepřijatelné. - Led deska je dobrý kontakt s chladičem a je stanovena s kovovou svorkou, takže se nepohybuje.

Cons: - It's a pity this one doesn't come with a small protective glass. - The bulb gets hot, but the good airflow makes the heat nothing unacceptable.

Other: I hope they last a long time because I'm going to order ten more of these to replace all my home's hallogen bulbs. ;)

Pros: + Price is very low (like 3-4 halogen bulbs) + Good quality + Illumination is more than 35 watt galogen lamp (about 40-42) + Slightly colder temperature than halogen + Looks great (aluminium radiator is looking good with aluminuim lamp) + Wide angle

Cons: - Need some protection - Also need some grease for better cooling

Other: Halogen bulbs are 4x cheaper,but they last 10-15 times less and consumption is 5-7x higher. So we have profit! I like its price,how they look,all is done in excellent way.

Pros: Cheap Nice, warm color temperature

Cons: Low quality No protection of the LEDs in an open lamp

Other: I can not recommend these bulbs, unfortunately. I had initially thought that I would try them out and if good - exchange many more bulbs for these. No go on that one now, the quality is not good enough. I have gotten nowhere near the expected life out of these and will look for other, better quality LEDs for my other fixtures.

Pros: Wide spread of light, can light up a large area. Color not as warm as a halogen but still okay.

Cons: Not as bright as a 50w halogen. The SMDs are exposed, a protective cover will be better. The PCB is only held lossely by a wire clip onto the heat sink. Sharp edges on the wings of the heat sink.

Other: Good price, good spread of light. Only time will tell if they last. Worth a go as the price is not bad.
