These bulbs were exactly as described and they are high quality bulbs and will last about a year. I have used Phillips bulbs since installing the system 14 years ago and have been happy with their durability. My light is on a timer for about 6 hours each night. Note that you must wear gloves or handle cloth or paper when installing halogen lamps, as oil from your skin can create hot spots on the glass, causing lamp failure. prematurely. I've tried cheaper bulbs several times over the years but have always been frustrated with how quickly they burn out.
