Fresnel: 1M/G40/23, 1500/G40/21, 2M/G48/5 are the three lamps rated for this
fixture. None exist in my lamp spec. notes.
(This is either out of the
Photometrics Handbook or Phillips Lamp Conversion Chart - don't remember which if either.) Could be off the
Kliegl Bros. (Historic) website.
http://www.klieglbros.com/ Kliegl as a brand name went out of business in the late 1980's, they no longer exist as a company. (Sorry, no upgrade kits from them.) Contacting the webmaster of the website however given Kliegl is the name and history they are trying to preserve might lead to some ideas on who to talk to about lamps for the fixtures. Most or many fans of the old company such as I have at one
point or another no doubt checked in with it in thanking them for the website and preservation of historic info about fixtures still in use. Eric’s (one of the webmasters) is good people, believe he is even a member (inactive) of this website. The guys running the Kliegl website beyond lamps might help in giving advice for resale of your fixtures so as to buy newer ones or who might be interested in shopping for ones of your model - never know until you ask what they know or could help with. Should you speak with the guys from the website remind them of
Controlbooth for such a question they should have been all over in checking into every once in a while.
Other options: Such fixtures and parts at best exist on E-Bay (rare) and possibly on the shelves of Vara-Light/Dimatronics/
Hub Electric (Old parts Dist., Owned by
Altman) 6207 Commercial Rd. Crystal Lake, Il. 60014. (815)455-4400 They are the only company in existence which is known to have been over the years buying up the parts for
incandescent S/S
fixture companies that go out of business. They would or could also have CD-80 parts in
stock (another post topic). I’ll run a check in the morning to three of my lamp suppliers in seeing if they have any of this discontinued lamp in
stock (doubtful) but also it’s possible
Hub might have some discontinued lamps. Could be they dont'
stock lamps, in that case if they are of the mood they might reference you to old time sources potentially having this lamp gathering dust on the shelf.
The Kliegl Brother’s Website also has a few other websites for sales/service in parts to check.
Contact the Antique
Bulb Collector’s Forum also, some of the guys from that website might know of sources that have old lamp collections for retail and or even be able to re-filament and make the lamps live another day your bad lamps. This or perhaps even buy up your old even bad lamps that are no longer useful in that
fixture. Perhaps even buy the
fixture. As with any forum, read the rules of posting first and perhaps contact the webmaster before posting so as to ensure your post follows the guidelines of posting best.
http://www.bulbcollector.com/ Lots of old lamp type experts on that forum that will jump at the chance to help you on this lamp type. The guys on this website know more about lamps than anyone has business knowing. (Yes, there are bigger lamp nerds than I in the industry.)
I know I certainly do not have this lamp in
stock... that would be all I need in having to justify it’s existence - loss of profit on my end of year accounting inventory of lamps. On the other
hand, I’ll stick my hat in the
fan in saying I would also be someone that has lots of experience in making something into something else such as these fixtures. I could even make them
LED should you wish - been there, done that in addition to having in the past made 10Kw Fresnels into 1Kw ones, yet that
bench focus of the lamp still being centered on the
reflector once I was done. Lots of Euro fixtures converted to American, lots of other conversions in the past even 9-Lite mole lights converted to six light with
strobe lights stuck in the center of them.
No doubt a few
fixture tinkerers/fabricators on the site and elsewhere who work for places would also jump at the chance to
play with such toys.
(You pay for such types in allowing them to tinker or
play with your gear on the other
hand, thus it’s half harted the offer that I would tinker for pay with your gear - my rate is not cheap in doing such things due to work load and experience in doing such things. That’s a corporate type thing and at any moment in the day I more juggle any one of six projects that need to get done very soon than have time to focus on any one over another. Adding another project to my day costs money in taking me away from a fully booked schedule thus I’m not seeking more stuff to work on. In part also why I don’t advertise where I work in generating sales during my off time from work. Would love to tinker with the lights, no time.)
Hub no doubt could also do a factory quality retrofit of the
fixture. Have to
call and even visit them one of these days - as much as I speak highly about them one would think at least once I have done business with them. Overall, it’s possible to upgrade such fixtures, but would take some measurements and calculations in doing so - that’s a touchie feelie type of thing.
This is a Big no doubt heavy 8" and powerful
Fresnel. You won't get a 2Kw rated 8"
Fresnel for under $100.00 these days. (Perhaps a very trashed Mole light for that price but it will also need serious work.) Replacing it with something rated for the same wattage isn't worth the price - much cheaper to fix it and or upgrade what you have. This assuming that you want to have as much range in wattage as the
fixture is designed for. This is a classic 2Kw movie industry Studio
Fresnel, it would be a shame to only do 1Kw out of it or make it into something lesser. Otherwise it might be cost effective to replace the fixtures with some 1Kw
Stage 8" Fresnels if 1,000 Watts is the normal wattage and save/preserve for a later generation with cash and interest in making a historic antique work to spec the Kliegl fixtures for future needs or bringing up to
par. I would not as advice recommend this
fixture for continued use as what it is. It either needs to be an antique museum piece for you or somewhere donated to or has to be upgraded to another incantation of a 2Kw
Fresnel. As a 1Kw
fixture it probably is not worth upgrading unless you really want to keep using it.
I would upgrade the
fixture if saving it and intending to use it as a up to 2Kw
fixture, to a G-38 (Mog.
Bi-Post) lamp
base (assuming a P-40s already) so at that
point you can use the very common locational
Fresnel CYX lamps at 2Kw (or better yet, Thorn CYX HX-2400 lamps) or lamp down to the 1kw CYV or 1.5Kw CXZ lamps as necessary. This assuming that such large lamps once retrofitted will fit in the
fixture. Given I don’t have the
fixture on
hand and the lamp specs, it would take some reverse engineering and measurements to re-focus a completely different lamp and lamp bast type into the center of the
reflector now. This is all theoretical thus on my part in yes, it’s possible but what solution is possible I would not
stand by until I started tinkering.
There is also some very long life and medium long life lamps available for the
fixture in these 1Kw/1.5Kw/2Kw G-38 wattages that would balance lamp cost with lamp life in exchange for lamp life. Not much available but there is some. This given it cold take a CYX lamp with at least 1" clearance between glass and top of
fixture, yet still center the
filament on the
reflector.
Not sure if I were normally doing a 1Kw lamp in the
fixture if I would bother upgrading it but unless the above lamps were too tall in overall size to fit - possible given a G-40 lamp used to be in the
fixture, the as said "BTL" series of medium
pre-focus (P-28s) lamp would be another option for lamps that are now shorter. The 500w BTL would not have enough output/punch but a 1Kw BTR would be a good start. Not a great lamp life or efficiency on the BTR lamp. As another option, and given Osram/Sylvania still makes the 1.2Kw FSG lamp, it would be the highest output medium-prefocus lamp on the market and your
fixture should you not be able to do the Mog
Bi-Pin (G-38) lamps above, the second best option. 100hours on this lamp so buy lots of them if available. Than of course if doing an upgrade one could also just upgrade to something such as a FEL in a G-9.5
base or even JCV 120v-1200w/CH in the same lamp
base but having “more
power.” Just waiting on the day I get to upgrade a
Altman 1000 follow spot to
play test this lamp. Too bad in the case of the follow spot that the FEL-R lamp is discontinued I believe. A FEL with internal
reflector might be useful...
OK Van. - great details but you need to specify if it's Mog Screw, Mog
Bi-Post or Mog
Pre-Focus to make my life easy by way of cheating on the test given your answer.
Your notes on this lamp type and
filament type are much more extensive than mine. Give me all your info for my notes. If not, great advice and things to consider.
Not seeing these lamps in my notes so all of these lamps have to be pre-1986 GE catalog where my lamp notes start.
Closest lamp I have notes on is this, and I don't know if it's the same lamp - the
LCL measurement would be the key in this. Sounds likely but it's long gone.
1M/G40PSP G.E. #22203 (?disc.) (Disc.) CL, Incd. SP (HRG) 1 Kw G-40 c-5
LCL 3.15/16" Mog PF
Base Down to Horz 25,000 Lum 200hr
Long discontinued but some of my sources might have one or two on the shelf - I’ll check around.
Still my advice is that you don’t upgrade this
fixture. Preserve it in a coating of WD-40 in a plastic bag and with the origional even if bad lamp, and tuck it away somewhere for another generation and a later day. Leave a note on it or all the notes you can find on it with a do not open tag. Let someone else in the future have this or these fixtures. Leave them your mom’s phone number with your name in contacting you in a future day should they wish to work on them and wish to contact you by way of some permanent phone number.
It’s an antique that savely unless you really need a 2Kw
fixture can safely be removed from your inventory and replaced. Don’t upgrade it unless you really cannot afford to do otherwise.
