I took James' advice and read through previous threads on the Ushio Ultraline 10,000 hr bulb. Does anyone know if they revised anything in the manu process for these? The thread was 2 years old that cited significantly bad feedback from installers. I just put in about 25 of these, and told the client to change them in two years with a servicing. I'll be away, so I hoped it would be a good idea to go with those bulbs. Oh, well. I'll follow up here on the results. Geez, now I wanna go back and see if they all look yellow.
