Review on Long-lasting Watt GU10 Halogen Bulb Light for Illuminating Spaces by William Dean

We bought these lamps less than a month ago. We installed six power rails in our kitchen. Unfortunately we had 3 dead bulbs in the first week. At the moment one more has died, so we're left with one of the original six. You shouldn't even try to install the other four as replacements. I contacted the seller and he refunded us the money. This improved the situation but did not solve the problem. Our devices are very difficult to access, so a lot of time has been wasted. I would not recommend these lamps.
