I just did a lamp comparison.
I can tell that the 24V200W ESC lamps from this site here (brand is Donar, but it does'n say so on the site) are very dim.
https://www.replacementlightbulbs.com/lampesc.html
I bought 4 of those and threw away my money on that.
I compared it to another 24V200W HXL EJL lamp from Osram, and that lamp was clearly brighter and whiter, only because it is an EJL mirrored lamp, the light has no conformity to the corners of the screen.
If a replacemet of 10mm backwards is also enough to use an EJL HLX, we could use this lamp for a brighter and whiter picture, without a complete transformator conversion.
- Has anyone done a lampholder backwards replacing with this 200W EJL and how much was needed?
Than I tried the just arrived Osram 24V250W HLX ELC lamp, and MAN what a bright and white light is that, and light conformity also not all the way to the corners, but better than the EJL, and this with the lampholder still in it's original space.
So I think that if a ELC need to be replaced 10mm backwards, the EJL probably need 15mm, or even 20mm backwards.
The 200W EJL HLX will than probably be comparable with the origenal Fuji ESC (I assume, cause I never had one), but a bit whiter and cheaper.
This can be achieved without going trough the hustle of an extra transformer conversion.
If you go for the complete transformer adding conversion, I know you'll end up with an even much brighter picture.
And compared to my Donar ESC lamp it's even twice as bright to the eye.
I also bought 2 of the Philips Focusline version of this 24V250W 31363 ELC which seems to be even brighter than the Osram, but I did not yet received those.
Can hardly wait to see that.

Steve Osborne of the reel image has the correct Fuji lamps, and are correct without any movement of lamp to gate distance. The Fuji has one coil more than other lamps of the same voltage and wattage, plus the multi faceted reflector which help focus the lamp. This is plenty bright enough for the three blade gs 1200. Bill's upgrade has certainly caused some ripples amongst the gs owner wanting more light, but unless you are able to undertake the conversion successfully and safely, the Fuji lamp is still very good, even if it has a short life span. The two blade shutter is a good upgrade and will add more light output again, so will the f1.0 lens. You just seem to be going round in circles, four pages later you are no closer to a conclusion, cut your losses and buy the Fuji lamp, its the safest option short term.......

I just placed an order for the Fuji ESC 24V200W at the Real Magic Store.
Also a 2 Blade Shutter and all sorts of stuff like; Filmguard Film Renew and a lot of film leader.
I hope that the FilmGuard and Renew can be shipped to the Netherlands as well.
In the mean time,...
Looking at the Fuji ESC bulb there, you can see it has facets all over, which helps with focusing the brightness, apart from the extra coil of course.
I also just ordered this lamp as well for comparison.
Philips 13631 24v 250w
8711500410757
It has facets, just like the origenal Fuji ESC has.
See photo.
Anyone already tried this one out?
Because it's not an ESC the lamp should probably be moved backwards, but we shall see.
Before doing that, I really like to see how this compares to the Philips Focusline and Osram, and of course to the origenal Fuji ESC.
A lot of testing.
Cannot wait to see the Fuji myself compared to the Donar ESC.
After that, I'm really curious how much it adds to use a HLX 250W lamps in comparison.
I think the whiter light will be the most offious.
This is actually a lot of fun, only it is a pricey test.
The lamps come from all over.
I have a Spectoradiometer and a colorimeter, so I shall do some testing with those as well.

I dont have the Fuji ESC yet, and my lampholder is not yet removed 10mm back.
On its origenal place this 250W Facet reflector lamp gives a very even bright light on the screen which is brighter and whiter than the Donar ESC lamp.
Can hardly wait how the Fuji lamp will compare.
The Osram is brighter in the middle but has darker corners, but as we know, this lamp needs the 10mm back.
Not sure if the whole picture than will be as bright as the hotspot it shows now?
Than I know what the end result will be.
For now I'm very interessted to see if this facet Philips lamp would be better than the Fuji ESC, still on the origenal place.
Interesting for people who don't like to move the lampholder.
I also received my order for the Philips Focusline that I ordered from Germany, because we don't have those here.
What I received was a totally differend Blue Phoilips package instead of the Focusline.
I could have bought that here as well and would have saved me the shipment.
I did put those into my GS1200 to compare it with the Osram, but the Osram is a whole lot brighter.
As soon as I receive the Fuji ESC lamps I will setup a whole measuring shootout for all the lamps and post it here.

Its a m33 lamp, in the Philips reflector, cheaper than the elc 24v 250w standard lamp. Looking at the Fuji lamp some are not lined up correctly and square to the outside reflector, this maybe the cause of the 12% loss of light, but if your prepared to cut the reflector and replace it with m33 lamp, you would be better replacing it with a HID 12v lamp, which is as much a conversion as this is, only cheaper and much brighter and whiter than either lamp. Philips do a long life lamp in this range, 500 hrs and 1000hrs, they are around the same price as the original Fuji lamp, but last much much longer, and they are very reliable on those time figures, as I use them all the time for lighting fixtures, fit them and forget ..........

Hi Thomas, its a car headlamp upgrade kit, these can be bought on ebay, and they come with ballast, you need a stable power supply which I think you could make yourself, I bought a multi tap power supply that's used for cctv. No flicker on the screen that I could see, checked against the beaulieu it was nearly as bright in my 3 blade gs 1200, if you have a two blade shutter gs then it would probably be closer to it, very bright even white light, I used an old Fuji lamp reflector, and set up a good Fuji lamp against a wall to gauge spot size and even ness at the same distance, this was good enough.
