FYI, after a few hours of supervised running, seems like this was the problem.
The tech kiddies will get a 'splaining of what not to do next time.
So many words above... FEL lamp with replaced, but the lamp sockt in need of replacement? Some posts above answer to do so. By the way don't re-use the lamp installed in a bad lamp socket or you could destroy the new lamp socket. What lamp/s were in use with a bad lamp socket are best to get rid of
More a question of education of the classic concept of putting a perfectly good lamp into a perfectly bad lamp socket.

If it's an FEL source, leaving it burning is just using up lamp hours. Shut it down whenever prudent - like, if it's not going to be used in the next 10 minutes or so. Less, if the on/off cycles aren't going to be distracting for nearby patrons.
The "leave it on" mentality doesn't typically apply to non-metal arc sources, which do take time to stabilize and which do lose multiple lamp hours per lamp ignition.
Also, you might want to try using an GLC lamp in place of the FEL. Similar output but lower wattage, similar cost, slightly less heat going through your consumables, and a more compact and efficient filament.

Average 1,000w/120v FEL lamp 3,200°K/27,500 Lumen/300h
Average 575w/115v GLC lamp 3,200°K/15,500 Lumen/400h
Agree with the above about most. have not tried GLC.
GLE/HX-755 might be a better option.
Average 750w/115v GLE lamp 3,050°K/17,400L/1,500h
I have notes of a lot of lamps, probably well discontinued such as the HX-800 or others in the 750-1.2Kw range. Smallr filament doesn't always help if fixture has a big old hole in it's center of the reflector. Altman 1000 verses Altman 1000Q is a big detail for upgrade.
My recommendation if one wants to max out this followspot is the JCV 120v-1200wCH Ushio #1000972 if still available. 33,000 Lum 200hr.
The most efficient lamp for output/color temp./lamp life if you don't want to increase or decrease output... in really by way of serching... this is still the FEL for this follow spot. Smaller filaments in point source of light do not always equal more actual output given other factors such as an internal lamp reflector adding as told 15% more lamp efficiency.
The Philips line of #6981P lamps designed for the VL-1KD fixtures are also more powerful than even the GLE lamp.
750w/115v, 3,200°K 20,500 Lum 300hr.
Stick with the FEL.

Huge can o' worms that topic. Type "followspot gels" into search box and stand back!

Heh, I did -- lemme rephrase. I want to replace the existing faded gels as close to factory as I reasonably can...
Empty. Filled at LD's discretion and Preference.Wait -- or did they come factory with empty holders? I don't wanna think....
