Welcome to BigScreenBiz.com

Sorry for the teaser title! This is actually about booth xenon wattages, but the name relates!

Can anyone specify how to properly cool each wattage of xenon for 35mm?

1,000-watts to 2,500-watt lamps are air-cooled and so are the projector traps.

3,000 watt and higher the lamps are air-cooled but some projectors, Strong, Century, Norelco, have water-cooled traps. Christie projectors have air-cooled traps all the way up to 7,000 watt lamps.

I have never seen an installation with more than a 7,000-watt lamp for 35mm film.

IMAX projectors routinely run 10,000 to 15,000 watt lamps, which are water-cooled. Water actually runs in the lamp itself.

HELLO ANDREW <> Most specs require keeping the bulb seals below 600 degrees F... A blower (or blowers) rated at about 600 cfm seems to be the most usual recommendation, but you need to be careful about duct length and elbows which create static pressure, and reduce the output... Lamps of more than 3k watts will probably require more ventilation, and the lamp & lamphouse manufacturers should be able to supply the specs for their product...
