Hi there!

When in serious jepardy, try the 8mm forum!

I'm gonna have a film screening tonight (in 6 hours time at my end of the world) and I got hold of a new bulb for my Eumig 8001. I seemed to remember a 100W bulb would be the right one but after checking on internet it's supposed to be a 75W bulb!

Does anybody know if a 100W bulb will be ok or will things get too hot?

Any help will be most appreciated!

Celluloidish regards from Norway!

KURT!

I would personnaly not take the risk of putting a more powerfull bulb than the maximum advised by the manufacturer. I don't see any reason why Eumig would have state the bulb needed is 75 watts if the projector could run safely with a 100 watts one. If for any reason, you still try to use a 100 watts, limit the risk by putting your voltage selector on a higher voltage that the one you have at home, this will lower the bulb power. Of course this in only possible if you can select for example 240 volts on the projector when you actually use 220 volts in your home. But again, I would not take the risk.

Please try to find a plate on the machine (or a statement in the manual) that tells you the three character lamp code (EFP, EFR, EFN, etc.) you need and go by that. Information from the 'net isn't always as reliable. There is also at least one case I've heard of where Eumig used 75W or 100W bulbs in the same model at different times, so it is a gray area.

Projector lamps aren't the same as household lamps. There are all sorts of different voltages used. There's also a lot of geometry that has to line up. So it pays to replace them by matching codes. (What code is the old lamp?)

If it really is a 75W machine it is a risky thing to try. It's not going a hundred miles an hour on a bicycle kind of risky, but it would be overdoing the ratings of the machine.

It depends on what you are trying to do as well. For example, do you want to show a 200 foot reel or 600 foot? 600 feet gives things a lot more time to heat up. Three 200 footers are still slightly better than a 600 footer because there is cool-down time between the reels.

Using the 240V setting on 220V should get you to 84 Watts on the bulb, only about 12% high. If this works I'd go for it. (Good Idea!)

You risk burning out your transformer as the 100watt will draw current that the transformer cannot handle.
Here's a source for the 12volt 75watt EFN.

Hi there!

Thanks very much, Dominique, Steve and Maurice!

Lots of great advice here! I had a closer look at the projector and it cleary says on the back max 75 Watts! So fair enough! Looks like we're watching 16mm tonight instead!

Dominique, your advice is definitely a good one. We've got 230 or 240 Volts in our sockets here, not 100% sure, and I could select the 250 Volt connector on the projector. That would lower the bulb power but like you suggest, It's not worth the risk!

Steve, I bought the projector recently without a bulb but the seller thought it needed a 100W bulb. My fault for not checking this a long time ago! The projector is practically brand new so I won't risk putting the wrong bulb in it. And if I use the 250 Volt setting I would of course lower the watt on the bulb, but since I'm not sure if I got 230 or 240 Volt it's too risky to go up that road! We were only going to watch short films so I guess the bulb would have opportunity to cool down a bit between reels though....

Maurice, I'm not gonna risk damaging the transformer in the projector either so It'll be 16mm tonight. Very usful information. I wasn't aware of this!

Thanks again all of you for helping out!

This forum is brilliant, isn't it!

All the best, KURT!
