Hell all,
once again, I come to you for advice and guidance
!!! I am thinking about starting up a small 16mm cinema and have been hearing a lot about xenon projectors lately. I looked up a few on EBay and found them to be rather pricey. Is the price in unison with the brightness difference over a Halogen machine to ensure a crisp picture with a long throw projection or...? I already have an EIKI SSL-O (250 watt Halogen lamp) so please compare with the same to give me an idea
? Thanks once more to you all and happy hump day
!!!
Best,
ET

Hi Elyas,
As a rough rule of thumb, the low-end Xenon projectors provide 3 times the light output of the same type of projector with the 250W lamp so you can have a picture 3 times the area for the same brightness. This is equivalent to 1.7 times wider and taller.

Not much more of an improvement in picture size for a lot more money, plus the cost of lamp replacement.
I assume the light from a xenon will have a higher temperature than that of a halogen lamp which could make it appear brighter.

Hi Elyas do you have a xenophot 259 bulb in as adds equivelant of 50 watts more and a brighter whiter light so like 300 watt really. They are great the Xenophots.
Also can you get a decent lens with more light going through.
For reliability the std machine you have is much better really.
Best Mark.

Thanks a lot guys,
you're always a tremendous amount of help
!!! Mark, can I use the Xenophot for my Eiki? I'll look it up on ebay in the mean time
...
Thanks a ton,

Elyas, you can indeed use a Xenophot ELC for the Eiki, however, in my tests a Ushio bulb was brighter still. Surprise!
Posted by Mark Todd (Member # 96) on October 02, 2014, 03:16 AM:
Where do you get those Bill.
THe A1/259 Xenophot is great itself and cheap too Elyas but must check those out as well.
Best Mark.
PS don`t jump on the first ebay ad you see as people often try it on with the price.

Interesting take on lamps from everyone. For what its worth I absolutely swear by the GE ELC 24v 250W USA produced. A bright long lasting lamp I have found.
By the way if I'm just checking a film in semi daylight I usually change the lamp to a 'stage lighting or pool lighting' type usually about half the price.

Note that the link to an USHIO lamp in Mark's posting is for a long life disco lamp, in view of its long life its output is considerable lower than that of an ELC designed for a film projector.

Thank U all so much, that was quite some help from y'all

I believe this link from BulbAmerica shows you what I tried. Sorry, it's not in Canada.
Posted by Elyas Tesfaye (Member # 3356) on October 03, 2014, 08:42 AM:
Thanks Bill,
I noticed that it's got a way shorter life span than my current bulb of 300 hrs. Still, I could just use it for audience screenings
!!! Thanks a bunch and have yourself a great weekend
