GU10 Fire Proof Ceramic LED Base with Lead Wires

Pros: Very well build, no difference in quality with the ones you can get in Europe. The ceramic housing makes it appropriate for use with halogen light bulbs as well as LED light bulbs.
The wires are made of white silicone (not transparent as in the pictures), which makes them very flexible and temperature resistant.

Cons: You need to find the right mounting screws, they aren't included.

Other: Buy them if you like to install LED spots and if you have somewhat experience with electronics.

Pros: Una pieza de loza que resiste el calor de una lámpara halogena, con una cablería forrada de material adecuado para ese uso, hay que reconocer que este tipo de luz se mantiene encendido por largo tiempo, en este caso al no haber sobrecalentamientos de piezas de calidad baja no se produce olor ni peligro.

Cons: Nada que decir ya que cumple con los estándares eléctricos de mi país.

Other: Para ser una pieza que no se luce al público tiene una buena presentación con su envase individual y sellado, es una presentación que suma calidad.

Pros: It's cheap and it works.

Cons: Quality could be better. You can feel the metal inside while replacing the bulb isn't as smooth as it can be in a well built product. I think that it won't last for hundreds of bulbs replacements, but I also hope I wont be replacing so many bulbs while I need this product...

Other: It's exactly what you would expect.
