Good afternoon everyone, I have read with interest all the posts regarding the lamps for the GS1200. I think the more I read, the more confused I get.
I have recently obtained a GS1200, and like most people that show films, always strive to get a brighter picture. The lamp that is in my machine is the EJL type, but from what I can gather, it is best if this is moved back by 10mm, so it puts more light in the gate. My question is, how do you move the lamp back 10mm, am I being thick, I can't figure out how to do this without major surgery.
Also, is it worth paying around another £10 for the correct lamp?
Many thanks, and seasons greetings to all forum members and best wishes for 2018.

Clive

The EJL lamp is designed for use in 16mm projectors, this is why it is suggested that for use in the GS-1200 that the lamp holder is moved.
You can, of course, do this, but it's much easier to use the correct lamp for the job which is an ESC.

Thanks for the advice Maurice, I guess like most people we try to save a few quid, I can get a EJL lamp for around £14, which I know is for 16mm, and an ESC lamp for the GS1200 is around £24, unless someone knows where the can be obtained cheaper. I guess money talks.
But thanks once again for taking the trouble to reply.
Regards, Clive

Hi Clive you should find the light from the ESC is actually better though with the right filament in the bulb in the right place etc too.

Also you don`t put any strain on the GS1200 transformer ( no worries if the 200 not 250 watt one) .

I think you would find it overall better value.

Best Mark.

You can get the A1/259 EJL`s from about £3, even Osrams about £4 each if you buy in bulk just out of interest. But I`d stick with the ESC.

Posted by Maurice Leakey (Member # 916) on December 23, 2017, 04:29 AM:

I must correct the comment made by Mark.
He quotes the EJL as an A1/259, however, the A1/259 is actually an ELC. The EJL is an A1/252.

Posted by Mark Todd (Member # 96) on December 23, 2017, 04:58 AM:

Yes thats right sorry.

Ones 200 EJL the other 250 ELC watt.

People often use the ELC for more whoomph, but its not quite right for the film gate like the EJL.

Best Mark.

Posted by Maurice Leakey (Member # 916) on December 23, 2017, 08:51 AM:

Yes, but the ELC might burn out the transformer as it's 250 watts.

I recommend staying with the ESC bulb. It is out there you just have to find it.

The GS 1200 is a remarkable machine. To take such a risk as to try other bulbs that fit the socket and actually light is not a wise thing to do.

Imagine what would happen if you put water in your car's gas tank instead of proper fuel........

Hi Chip, Thanks for your message and words of wisdom. I have been told of a site in the USA that has the ESC lamps and are quite reasonably priced. I am waiting until the new year before I order any.
Best wishes, Clive

Chip is absolutely right about not using the 250 watt ELC lamp in the GS1200. Yes you can use it, I have done it and you do get an extremely bright picture, brighter than the 200 watt ESC lamp. But the risk of burning out the transformer is significant. Think about it, if Elmo thought that they could safely put a 250 watt bulb in this machine they most certainly would have done it. So stay with the 200 watt ESC lamp, unless you want to modify the machine for use with an external 250 watt power supply, as Graham and others have done.
You can also boost screen brightness by 33% if you install a 2-blade shutter.

I looked into getting the Fuji ESC lamp a few years ago. I spoke to a local lamp importer. The two things that put me of, one was the cost, but the other and this really was the big downer, was the lamp was only rated for a 25 hour life [Frown]

that killed of my interest in it quickly [Frown]

A quick survey here folks......how many of you use the ESC, and what has been your average life out of the lamp?

Clive Its easy to move the lamp holder back the 10mm, and what I have been thinking regarding your 200 watt EJL, and I should add its a lamp I hate with a passion due to its dullness, is to try the lamp at the 10mm back position and see what happens. There is a good chance the EJL might work a lot better in that position, if not simply move the holder back to its original spot.

I think its worth trying...it might just work [Cool]

Unless a large screen is wanted I am sure most projectionists would use the lower lamp setting.
It would be interesting to know how long this would extend the quoted life which I assume is at the full operating voltage.

Hi Graham, Thanks for the reply, I will be ordering the correct lamp for the GS1200 from the States in the new year. I will try them to see what a difference they are over the EJL lamps. If they do show a difference and they are still readily available, I might just as well stick with them. The ESC lamps in the UK do seem to be rather expensive, I can get them from the States cheaper than I can get them from the UK, and that includes shipping.
Regards, Clive

Your Welcome Clive [Smile]

Like Maurice I also hope to hear how others have found the life of the ESC lamp [Smile]

If you buy from the US I would suggest one at a time to order, otherwise you may get charged some import tax or VAT.
It might, in the long run, prove cheaper to buy in the UK.

Posted by Clive Casey (Member # 6202) on December 31, 2017, 04:42 PM:

Hi Maurice, Thanks for your message. I have only found one supplier in the UK that has the ESC lamp, and that is Cinema Paradiso. They are selling them for £23.95 each plus £3.95 postage. Do you know of some where else that sells them?
Best wishes for 2018.
Clive

You are correct. At the moment Cinema Paradiso seems to be the only UK seller, but he does offer a discount for a multiple buy of the lamps. I assume the cost is high as he may import them from the US.
At one time Blue Cine Tech were selling the Fuji ESC lamps but I think that supply has now dried up.

Hello at all!
I have tested the 200W EJL from Philips with the 10mm back Position. It was a very less Lightoutput. Here in Germany i cant buy the original ESC Lamp. Wittner had some of the Fujis 2 Years ago for 50 Euros. Thats to expensive for me because anyone said the ESC has only a Lifetime of 25 Hours. So I cut the 3 Lines for the Lamp in my Elmos and give them to an external Transformer with 24V/ 400w. So I use over 26 Years the ELC 250W Lamp with a very bright Picture also in 9foot Scope. Last Year I find out that the ELC 250W from Philips is the best or my machines. It is very easy to connect an external Transformer on this Machine.
