2016年4月2日 · A purpose made front-of-lens or lens replacement slide copier attachment might be far more reliable. As far as matching the light output of a projector bulb with an LED: At present LEDs are about 6 times more efficient than a Halogen bulb, and you'd need a compact LED source of 50 watts or thereabouts to match the brightness.

2014年3月30日 · <p>I have a Kodak Carousel 850 Slide Projector and also a 750. Both have the same problem, the tray does not advance from one slide to the next (Tray does not turn). Also one of the units is missing one of the two concave heavy glasses inside the unit.<br> I have the feeling that it's due do a common problem like a broken belt or broken ...

2019年9月9日 · It is not uncommon for halogen replacement bulbs, even LED replacements, to destroy automobile parking and tail light fixtures when used inappropriately. Some LED headlights have finned heat exchangers and built-in fans. So in a few words, high intensity lamps of any sort get very hot, and stay hot just as long as their incandescent counterparts.

2009年10月28日 · <p>I think your AO projector is just fine, if you can find bulbs for it. As for cooling, try a slide of low value and see how long it takes to "pop" under continous projection and how warm it gets. 300 watt is fairly low and with a fan your projector may well do better than newer 500 watt projectors in the heat category.</p>

The Prado 150, like so much of the Leica implements of the '50s, has a very hand-on, almost funky character. But pleasing.

Buiilt like tanks but I always wondered about bulbs for them.</p> <p>I bought a used Kodak 35mm projector, which are extremely delicate, and had no problems having it shipped from the US to Canada.

2004年3月31日 · Thus, I bring my Leitz projector to all my presentations. Mine cost me $450, bought used from Wall Street Camera in New York City. It is in mint condition. Since I do make money with the projector, I upgraded the projector by adding the "Bright Light Kit", which is a special order from Leitz. The cost was $160 from B&H.

2010年12月13日 · David--I think that Osram is the European branch of the U.S. Sylvania company. I figured that the projector would have come equipped with a European-manufactured bulb as an O.E.M. item. In any event, my experience is that Japanese and European manufactured bulbs last longer than to those manufactured in the U.S.

2013年11月7日 · A 35mm slide projected through a 100mm lens, will fill a 60" screen at around 15' (projector to screen distance). So the zoom will compensate for larger rooms.</p> <p>Raynox made commercial grade zooms for Kodak carousels.

2008年2月2日 · The Kodak Carousel/Ektagraphic line was the most widely sold slide projector ever made and Kodak discontinued them only about two years ago, with many new ones still in the system today. Of course you can still get bulbs for them from any real camera store and from places like bulbman or any other bulb dealer.
