The bulbs I prefer in order of preference:1. Osram: probably the best bulb made these days 2. ORC: Nice strong light and lasts reasonably well, although in some lamphouses (CFS and Super Lume-X) they can be finicky on auto striking. 3. Christie/Ushio: Another well made solid performer. Aaron

I am surprised at how short everybody's bulbs seem to be lasting. We use Christie 4000 and 2000 watt lamphouses with Christie CXL40 and CXL20 xenon bulbs, respectively. Our 4000 watt bulbs are warranted to last at least 1200 hours, and they usually reach 1400 hours before they start getting dim or flickering. My record for a 4000 watt bulb is about 2100 hours, and it looked OK (not good enough to leave it in, though). As for our 2000 watt xenons, well, I haven't had to even change one yet since the theatre has opened a year and a half ago, just refocus here and there. The one with the most hours so far is about 4400 hours and it looks great -- no flicker or dimness at all! They should easilly last to 6000 hours and maybe to 7000. We'll see. OSRAMs can last even longer and put out a better looking light, but the Christie bulbs are good. The Christie bulbs do not say Ushio anywhere on the packaging at all, even though Christie Inc is owned by Ushio America.

>>"Christie bulbs are fine, but OSRAM is definitely better. If you install
an OSRAM and a Christie into 2 equally powered lamphouses in the same
building at the same time, you will notice that the OSRAMs last longer
(also cost a bit more) and look better onscreen. The Christies put out a
very blue-ish light whereas the OSRAMs are very white. The diference is
very noticable when you can do a side by side comparison. I would go
with the OSRAMs because you will change bulbs less frequently and save
$$$ in the long run. ORC bulbs are stupid"<<Funny...I have done this very test and the Christie lamps out lasted OSRAM (and ORC). Osram burned their bridge with me in the mid '80s with their "it isn't my fault the lamps arrive broken, blow-up, flicker, don't have any gas in them...etc). My favorite line from them was the "in-rush current" thing. It is amazing how my in-rush current problem vanished when I switched to Christie lamps. Christie lamps main mode of early failure is out-gassing...much better than an explosion. I generally get the longest life on Christie lamps with Christie power. I once installed a 7-plex with the Christie package (sans projectors...Centurys though I'm normally a Simplex man)...those lamps REALLY went the distance...I believe one of them went to 14,000 hours and was very scary to change. The damn lamp really didn't darken but took about 5 minutes to sabilize at the beginning of the show. I changed it years after installing the booth during a union training seminar on lamp changes. I feel that the OSRAM lamps have gotten better over the years though and the theatre I work at on Saturdays uses them though we have used Christies here too. The Christies generally lasted longer (and were more stable). Steve
