Nice, bright bulb
I couldn't find this bulb at my local hardware store, which was surprising. I ordered this bulb to see how well it worked. It is nice and bright. It is dimmable for when I want to watch TV in low light.

Great to find these
With all the LEDs in lighting these days, it is hard to find these dimmable halogen locally so I appreciate Amazon having them. One of the four bulbs did not seem to work (might have been my installation skills), but the others are fine. They last so long, I did not really need four, so I won't miss the one that didn't work.

Even though they may not last as long, this is a way better deal than others.

Good Brightness at a Great Price!
These bulbs put out just the right amount of brightness for anyone needing to do auto mechanics at night or in a dark garage. I also like that they don't produce nearly as much heat as the 500 watt bulbs. Though, they still do get hot because they are halogen bulbs. I use these bulbs to revive an old work light I picked up at an estate sale. Installation was a snap. HINTS: Do not touch the bulb's glass with your bare fingers as the oil on them will cause the bulbs to burn out sooner — wear gloves. If you do touch the bulb's glass, you can clean it with glass cleaner and a soft cloth — just allow the bulb to cool off first.

Extraordinario producto y atención.
El producto cumplió con las especificaciones ofrecidas; venía perfectamente etiquetado cada foco; los focos estaban muy bien embalados, y se recibieron en un tiempo récord. Muchas gracias.

Me ha durado más de lo prometido en el empaque
Lo he usado más horas de las que promete el producto y sigue funcionando El empaque promete 1000 horas que en realidad es poco pero por eso ofrecen más bombillas por el precio que otras marcas ofrecen una o dos. Me ha durado más de 2000 horas. Esperemos que cuando esta bombilla caduque las otras funcionan igual de bien.
