I switched for the lower power consumption but mostly because the OEM bulbs got so hot that the fixture would be hot to the touch. When I pulled the cover off to look at the factory bulbs, the socket base for the bulb had been singed on almost all the fixtures. I replaced all with the ones below from amazon.com. I think there were 18 in all and the cost was about $80 for all of them.
