EXCITER LAMP TYPE BRK G27 FOR ELMO 16CL PROJECTOR NEW | eBay

[Dominique De Bast]

Bad news. Thanks for the warning. Maurice.

[Alan Myers]

This link goes to a G29, are these the same?

[Maurice Leakey]

Sorry, Alan, I made a mistake, and inadvertently showed a link to a G29, which has a different filament position, and is used in Bell & Howell, also Rank Aldis and Bauer.
I have now corrected the link to a G27 BRK.

[Terry Sills]

Don’t pay that ridiculous price. Message me, I have many exciter bulbs which I no longer have use for as I sold all my 16mm projectors.

[Terry Sills]

Sorry - now out of stock for G27 exciters, but have many other types. Also many projector lamps. Contact me for requirements.

Hi!

FYI: FFR is still selling BRK exciter lamps for 14€ including VAT:
http://www.ffr-film.de/eng-tonlampe-.html

„Tonlampe“ or „Lichttonlampe“ = exciter lamp
waagerecht = horizontal
senkrecht = vertical/upright
„Best.-Nr.“ or „Bestellnummer“ = order number
Stück = item (in this case: exactly one item)
Sockel = socket
Lampe = lamp

When you need other words translated, then please post your questions here. I’ll try to answer ASAP. But I am usually only reading this forum in the evenings (CET).

Have fun with your Lichttonfilme (optical sound films)!

Terry, would you by any chance have any of the old 115 volt 200 to 400watt standard pre focus base bulbs? It would save me having to convert my old Pax to halogen. I have done a lot of mechanical and audio modifications but it still runs on the original transformer. Ken Finch.

[Terry Sills]

Ken
doesn’t the lamps for the Pax have a Pathe ‘T’ fitting on the base? If not can you show me a picture of the lamp base type you are looking for.

[Ken Finch]

Sorry Terry, I am not able to show you a picture. My computer skills are not up to it !! However the PAX does not have the T base it has the same base as the Specto 500 and many other projectors used but NOT the Debrie or. Bell and Howell. I am pretty sure that the Ampros and some slide projectors used the same base. It is like a standard bayonet base but with 2 small flanges at the top instead of pins. It was known as the standard pre focus base.Hope this helps. Ken Finch.😊

This is something that I have been working on now for quite some time. It is to produce a new exciter lamp, that houses a laser diode instead of a tungsten filament.
This uses the same bayonet cap base, it is powered by the projectors supply so there is no modification needed. Simply push in and turn as you would do with a standard exciter lamp. There would need to be two models produced one for super 8 and the other for 16mm.
Using a laser there is no need for different orientation as there is with a filament.
From experimenting with this on a 16mm projector I found that there is a great improvement to the clarity of sound and also volume.
All of this is work in progress at the moment as I keep finding new ways for improvement, this includes an adjustment so it is possible to fine tune the alignment of the beam.

I guess this is the type you are looking for, but the lowest wattage I have is 500w 115v. I do have 200w but they have the Pathe T piece
fittment.

[Terry Sills]

Ken
what I do have is loads of these 120v 300w lamps (more than a dozen) but you would have to convert the lamp holder to take this type of fitting. In the past
I converted a Pathe 200b to take this lamp because the original lamps were nearly impossible to find. Let me know what you think.

[Lee Mannering]

Yes plenty on ebay if you get stuck, usually around £10 G27 372137413633

[Ken Finch]

Thanks Terry. I would be interested in the 500 watt lamps as they are for the Specto. I will have to look into the possibility regarding suitability for the PAX as it’s transformer may not be able to cope with the extra current and heat.Ken Finch.
