Good thing there is only 30, otherwise it may be a baked egg.We only have 30 Par64's in the air, two systems of backlight.
Although with the scaffolding I've seen recently, maybe they are trying to crack it open?

Is there any more info on *why* the lamps were recalled? We just spent hundreds of dollars on lamps a few months ago and they're all subject to it. At this point, I don't even know where they all are. If the reason is "they burn out too quickly" I can deal with it. If the reason is "they explode" my reaction's going to be a bit different....
@DELO72 , So the FEL should continue to be the bane of @derekleffew ‘s existence for the foreseeable future?
Westinghouse's 750T12/9 lamps were the best!Derek likes them because they are what they are, as with asbestos wiring.
Strand-Century and others "solved" this beginning in the late 1960s first with flatted, then double-flatted reflectors. The ellipsoid is made of may squarish planar facets, each positioned to reflect the filament through the same point in the gate.
There's lots of volume inside a Fresnel and the spherical reflector isn't very good at reflecting all of the light. Whereas in an ellipsoid, light, heat, and sound are all reflected save for the void of the hole in the reflector.Halogen vs. Incandescent... yes that is a factor as with cooling, but mostly the robust earlier designs will or will not take the heat. Mostly will when wired modern and maintained, but depends on situation. 6" Fresnels of all ages since the 1930's have never had a problem with halogen upgrades other than in wiring and maintaining.
I give you the 1975-ish fixture using a hybrid PARAbolic, ELLipspheric, SPHeric reflector, the Electro-Controls Parellipshere....in an age before computer drafting.
If you want to pay the shipping ill GIVE you a Patt 23 and Patt 123. Got lots. Parellepsheres are harder to find now though... That last theatre I know that had some still was the Blyth Festival Theatre, and they got rid of theirs a year or two ago (sold for scrap). They were really great lights really however they are HEAVY and LARGE.Caught my easy point on the Fresnel in making a concept point - good job, but vaiid in not too many reflectors burning up.
But fascinated by your reply in history of how they were designed I only suspected, cool thanks you knew all that off hand. And now the world knows how/why.
On my get list the Parellesphere (Philisphere?) as with a Patt 23. I have a Daughter and bills and no longer am spending money on E-Bay stocking the museum.
Again old guy.. friend, when are you coming to visit and help identify some lights?
