For about the same price of the halogen bulbs, which burned out on a regular basis, these LED bulbs should last much longer. They are in a fixture that contains 4 bulbs controlled with a dimmer switch. They work great and are slightly brighter than the original halogen bulbs.
Received GU 10 bulbs in perfect condition even though these were shipped across half the globe. Price very competitive. No damages. Happy so far. The only hitch is that one type did not have the CE label.
