This is an excellent, inexpensive solution to these expensive bulbs. Based on this, I came up with using a extremely bright "flash light" LED, positioned it just right and it worked.
Checking out Amazon, replacement DJL bulbs are going for anything from $60 to $280! ENH bulbs on eBay start at $6. Your hack is a godsend that I will try to replicate. Thanks.
It works. But I have to warn you that extracting that ENH lamp from the reflector is not easy. I would recommend just purchasing a lamp module like this one. www.ebay.com/itm/292943497319
fantastic and perfect solution!!! congratulations! I realize an analogue solution in my DEF lamp (21,5V 150W General Electric but with glass mirror), with an halogen bulb G6.35 socket, 24 volts 150Watts (the lamp for slide projectors), for my Bell & Howell 8mm regular projector. very thanks for your wonderful solution!!! bye (and... sorry me for my English!)
I've read that handling a halogen lamp with your bare hands is a really bad idea and will cause premature failure of the bulb due to oil from your hand causes unequal heat distribution on the glass
Yes. Thank you. Most people know to use an alcohol or lens cleaning wipe whenever they touch any lamp. Or, they should know. Always worth mentioning for sure.
If it doesn't work out here is a link for a lamp module that will work great in your 456A. store.tvedenlampmodules.com/BH-projector-LAMP-MODULE-356A-357A-357B-358A-456A-456Z-457-458-458A-P3088300.aspx
Thank you so much for this. I have seen a few different ways to do this, but this is been the first one I saw that re-purposes the original Lamp. I have a projector I picked up for 20$ (The same one a 456a) and the lamp was working, up until I assembled all the parts, and got some film to play, then the lamp blew at that moment!

This was done and shown for entertainment only. It's not easy extracting the bulb from the base. As you found out. I would just buy a DJL replacement kit or module. www.ebay.com/itm/291025347853
It did not damage my projectors. But I make no guarantees to what your results may or may not be. If you want a good, reliable, affordable replacement lamp here is a link. store.tvedenlampmodules.com/DFN-DFC-DFA-DFG-Plug-in-Module-for-Bell-Howell-245-248-253-254-256-346A-OSAWA-P3149663.aspx
Hey Charlie. I ordered one of your bulbs on Ebay didn’t get it yet. But I managed to solder the one I was working on. It works but the light is very dim. The projector says use only DLG bulbs. Am I using the wrong bulb? Is yours the correct one? Feel like I’m wasting my time and money. What do you think?
Hi Doug, It sounds like you installed a 120V lamp where you needed a 21.5 volt lamp for your DLS-DLG projector. The voltage matters as much as the wattage, if not more. If you're doing a hack on a 21.5V projector like yours, you will need to match it with a 21V donor lamp, such as an EKE or ENB. We always suggest that you just get a kit or a plug-in module. Thank you and good luck.
Can’t seem to find anything under ENH or ELH when I search WalMart or Lowes websites. Is there another designation for these bulbs? What is the wattage/voltage of the bulb you used. I tried a 150 watt halogen as per a guy here on UA-cam, it works but it’s nowhere near bright enough to project an image. Any help thanks a lot.
Is there a reason that you did not use the reflector and bulb of the ENH? Looks as if the front supports for the original lamp could have been used for the new bulb and reflector unit.
Hey Charlie I have completed everything except soldering the new bulb to the contacts on the old housing. Doesn’t seem to be solderable metal? Any Suggestions?
Hey Charlie, can I order one of these from you? I can’t solder the wires to the socket terminals don’t know what kind of wire it is. Anyway I think you sell them. Also do you sell the large take up reels? Let me know thanks.
Hi Charlie, Just curious. I bought a plain bulb (250w, 120v) without the ENH housing. It has the ceramic bonding fully intact. Can I simply make a bigger hole in the hacked housing unit without removing the ceramic bondingfrom the bulb? Thanks for the informative video! Cheers.
I wouldn't make a bigger hole in the mirror as it will reduce the brightness... unless it's already bright enough for at least a nice 3 to 4 foot wide screen.
Thanks for a great video. Currently working on the reflector. Got bulb out ok. The reflector is fastened to the base by two tiny little points and in process of enlarging opening for bulb, it broke away from the base. So trying to figure how best to attach it back. Figure this might have happened tp you so I figured I’d ask! Maybe jb weld for that too! Any suggestions? Thanks again!

A few people have asked what bulb to use for a DFN-DFC hack. This one works: DONAR 27127. $9.00 on Ebay. When you're done clean off the bulb w/ some rubbing alcohol or the bulb will burn out prematurely. This is very important.
you can buy 12V g4 or g8 halogen bulbs without the reflector with no problem, why do you had to buy the whole thing with the reflector if you not using it?
That's great, but we're not using 12v lamps. Let me know if you can find 120v 250 watt halogen bulbs without the reflector. I may be able to get a large quantity special order from Donar in China, but I have spent hours and hours searching the web.
well looking for ohp bulbs there is much more 82V 250w ones for about 5$ each or 600W 120v :] but those are quite a bit bigger though I have no idea about us voltage ones though because in europe we use 230V standard, so i thought that 12 or 24 volt bulb would be more universal, did not expected that to work from mains voltage.
I just purchased a EIKI RT-O projector and i need to replace belts, the rewind belt looks good and the long belts ,but there appears to be 2 tubular belt sprockets that need belts that connect to motor and fan housing. is there just suppose to be 1 belt or 2 on each of these sprockets ?.
1:13 ENH lamps are 250w and ELH lamps are 300w. Since the original DJL lamp is 150w, won't this risk burning the film since you'll be radiating more heat than the original 150w bulb?
We have used both 150w EZK lamps and 250W ENH. For whatever reason, the 150w EZK and a 150w DJL do not output the same candle power. To get comparative output the 250w ENH must be used. We have used a laser thermometer at the film gate to measure temp. and the ENH is about the same, just a little cooler. Go figure. ;) Thank you again for the excellent questions.
Well thank you for the excellent answers as well! Halogens are slightly more efficient than incandescent bulbs (3.5% vs 2.1%) so theoretically you wouldn't expect there to be a huge variation in temperature. Also, output for halogens as measured in lumens is typically equal to or greater than that of an incandescent bulb. The only reason I can come up with for why this fails here is that I believe the projector bulbs run much brighter and hotter than a "typical" (e.g. household bulb). Just imagine staring at a 150w household bulb vs. a 150w projector bulb. I believe the projector bulb is going to be much brighter and hotter (and will blind you sooner!). Unfortunately, there doesn't seem to be any detailed specs. produced for these vintage bulbs regarding luminosity or thermal output so it's hard to answer this question analytically. It's "cool" (pun intended) that you discovered this and found a working solution empirically!
Thank you so much. We do use an infrared laser thermometer to get the thermal readings. The candle power comparisons are done side by side. It is interesting how these comparisons don't correlate with the lamp wattage ratings. Take care.
@@enigma7070 To answer your final point first, the projector bulb will blind you first because it is concentrated by the reflector. Also, remember that the voltage / current / wattage of an incandescent bulb filament is not written in stone. There is a range it can run at. Running any given filament on a higher voltage will up the current and therefore the wattage and thus a brighter, whiter output but at a tremendous cost in reduced hours while running on a lesser voltage does the opposite. For example, cut the voltage to an ordinary household bulb in half and the life doesn't double; it may go up ten-fold. Or more! The point here is that the projector bulb is running at the upper end of that range which is why they have such short lifetimes. That filament is of such design (thickness & length) that if you examined it and were told it was for a household bulb you might guess that it was intended for just, say, 90 volts. It would be a dimmer bulb but have a normal life. But it's made to run on 120V which makes it very intense but very short-lived. They ARE putting out more lumens per watt. And that's another reason the projector bulb will hurt your eyes more than the same wattage ordinary bulb. Which is why they came up with the halogen bulb which is also a type of incandescent and runs at the top end but the halogen principle keeps it going longer than it otherwise would. I'm sure there is a Wiki article which explains it. Now then, as to the question as to why it takes more wattage to properly illuminate --especially when it's a halogen bulb where you would think you would get away with less wattage? Most likely it is a question of optical efficiency. The halogen bulb in its original reflector had the filament at the precise optical center. I'm not familiar with the donor bulb so I don't know what size aperture it was intended to illuminate---anything from 2" slides to 16mm to 8mm. Likely the DJL also had it's filament properly located. But after the conversion it's doubtful that the filament is exactly where it would produce the greatest light output with the old reflector. It's amazing enough that it works at all. As a personal note, after watching The Deuce on HBO, I got a whim to buy some 8mm (regular 8) adult reels on eBay. But no way to play it but I scored two B&H machines off CL for just $25. I think one can do both R8 and S8. The other S8 only. Both have DJL bulbs. The downside is now I feel obligated to watch this crap. It's really boring. Once through on each reel and it will go sit on a shelf forever. Or maybe back on eBay. Hopefully, my bulbs will last but if not I will be trying what is shown here.
Hi Eduardo, If the internal reflector is made of metal not glass you should be able to make it work. The halogen donor lamp would likely be an ELB. There are a couple others too but I can't remember at the moment. I'll update when my memory (hopefully) comes back. Good luck.
Hi, Thanks for reply. The DLD has a glass reflector. Why can't I use it? Because of adapting the new bulb? or any other reason. Can you please write me to my email, edubarca1946@gmail.com because I want to send you some pictures I took of my DLD lamp. Thanks for your help.
