I'm going to have to disagree with the comments here, providing that the projector is calling for an EJL bulb as OEM.
If this projector uses an EJL bulb (200 watts) then upgrading to an ELC (250 watts) will be ok. I have done this on every projector I own that initially called for an EJL bulb after hearing discussions about it on another forum. And I have had zero issue, including running the projectors for double feature nights where the projectors ran for hours and hours.
And this quote is from Richard Burgess, who serviced Eiki's (The US version of the ELF) from back in the 70's and still does projector repairs to this day:
"For example, the Eiki's and Elmo's were originally designed for EJL, but all manuals were authorized and updated to accept either lamp. NO modification was done to the projector specifications or electronic components. My manuals from Kodak also authorized the ELC in the 250S in later editions. I never saw any modification to any component. The lamp components have no problem with either lamp.
I have never had a service issue with any of the 200/250 watt lamp circuit transformers in any of the Kodak's, Eiki's and Elmo's even though they initially came with EJL's as the OEM lamps. The only failures have been lamp socket contacts, not related to electronics. Contacts bend and then arc causing damage to the socket.
For what it's worth, he also said this:
You can use the ELC in the ST/M series Eiki's without a problem. The transformers are very robust and can easily handle either lamp.
Even the first RT series projectors came with the EJL lamps and stickers. The stickers weren't even updated for years in production runs even though ELC's became the OEM lamp for the projector. Owner's manuals were updated to say you could use either lamp. No electronic modifications were made, the same transformer from one series to the next, just some mods for the motors.
Hope this helps as the 250watt ELC bulbs do help with brightness esp. when projecting onto a larger area ![[Big Grin]](biggrin.gif)

Paul, keep in mind Richard Burgess was selling these machines new back in the 70's and was an authorized repair source for them as well (and still is). His history with 16mm projectors is WELL documented on the 16mm forum.
I would tend to think that someone who has as much experience, history, and dealings with Eiki as he has (and being an authorized repair source), that he would have been "in the know" if there were any running model changes to the transformer (or anything else). I would also go as far to say he wouldn't risk people damaging their machines by providing incorrect information. The guy REALLY knows his stuff and spanning 40+ years of repairing these machines, I'd be more confident to believe him vs. what I read on a forum from someone who is less experienced in servicing the Eiki/Elf brand.
Also given the amount of people who I have encountered that 'upgraded' their EJL 200 watt bulbs to an ELC 250 watt bulb (myself included) with zero issues, further makes me have confidence in his statement. Of course, anyone is free to disagree if they wish ![[Wink]](wink.gif)
