Gerald, with all due respect, what was in your mind to put a 12v bulb on 21v projector? [Eek!]

Gerald I just checked the voltage on the EJL bulb you mentioned. DO NOT USE IT....it's 24V 200W.

Only use a EKE or EJV.

Marriage made in projection heaven with QLV-1 matched to G17Q base. All you need is G17Q base, QLV-1 socket, masking tape, solder, JB Weld, spring clamp and a G17Q jig. Break any old G17Q base lamp such as DJL, DLH, DCH, DJA, DFN, ect. Clean glass down to base rim. Break out the corresponding rear electrical contact pins from the base. Use masking tape to cover open holes in G17Q base. Solder QLV-1 leads to fit as the new pins in the G17Q base. Use a needle or pin to poke a small hole centered the in tape covering the base openings. Place Base in an matching socket out of old parts projector. Push tinned leads down through the tape and base, into the socket. J-B weld it in the jig. Clamp it. After setting, pop the new lamp module out, and put the appropriate MR16 rated lamp corresponding with the wattage and voltage of the original lamp application. DJL= ESD, EZK, JCR/150/120, etc; DLH= ENH etc. Just that simple. Works like a champ! Good luck!

George this sounds great...but next time you do a conversion like this could you take some incremental photos to go along with your instructions. I'd like to try it...but I'm having trouble visualizing some of the steps. [Confused]

The Elmo FP-A projectors generally used a DCA (150W 21.5V) lamp. However, I discovered when I bought an FP-A projector for parts that it had a Halogen MR16 EJM (150W 21V) lamp. This must have been the Deluxe Model. So I removed all the lamp components from the junker and transfered them to my original FP-A projector.

Here is what the conversion looks like.

This is what the Junker FP-A Deluxe model looks like;

I don't recall where I saw it just recently, maybe eBay, but it was a conversion socket just like George made and they were asking $300.00 for it.

WOW...$300. It doesn't sound that complicated. I want to try and make one. Maybe I'll understand the instructions better once I start...but I get a little confused with the "jig" part of the instructions. I hope George posts some more pics.

Hi Janice and Barry,
Ummm... I'm the guy selling those on eBay and my website too. Barry, you were about $225.00 over the actual price though. I wish I was getting those prices. lol. [Smile]

It does take a few hours to make them, and the jig is the key of course. Although I'm a newbie here, I like the concept of this forum and the enthusiasm of the members. Although it would be easier and probably cheaper to buy one, it's a lot more fun to make one. That is why I wanted to show the plug-in module. I do make how to video's for YouTube and my website. I will send photo and print instructions for the jig free to any 8mm Forum member for private use only. Just send me a message with your email.
