Is a circuit necessary in this condition?

[roughshawd]

I have an American DJ Topaz 250 disco light that uses a special 250W 24v projector bulb that burns out after a few hours of use readily.

I think the burn out is because the bulb is getting hot, but that is the nature of high power projection bulbs.

The case of the topaz is small, and the bulb is in there with the electronics that drive a sound activated motor for a dichromatic mirror ball plate that spins the light effect around on the floor, and a trickling water effect that is always on.

The only cooling in the case was a 12v induction fan similar to the evacuation fans on PC cases. It has a metal shield above the bulb, that I would think probably keeps the fan plastic from melting after few minutes of operation. I am mounting this on a ceiling about 12' up and don't want to go up there and change the bulb every 3 days of fun, besides the bulb is really expensive.

So...(you know me!)
I got my hands on some of those old overhead projectors they used in the 40's 50's and 60's to show transparencies to a room full of idjots. They generally use high watt projector bulbs and have huge fan systems in the to keep it cool...(ah ha yes, I remember in Alaska when it was cold outside how we all used to gather around the overhead projector to warm our hands...)

I pulled the little fan and attached the blower to the hole where the fan used to be.

So the fan I got is tagged for 380w 82v bulb... should work pretty good on my little 250w 24v.

My 2 part question is about the little fans absents, and the new fans PSU source.

first part
The system fan is going to create quite a stir in the circuit if its simply unplugged and/or missing. So I am thinking maybe I should attach something to the plug where the fan powers, that acts as an inductor of the same caliber as the PC fan... say a .00025 ohm circuit with a temperature sensor that beeps if it starts to overheat??? What kind of terminator can I put in there?

second part
And the new fan has its own PSU system that has a much longer 110v supply plug-in cord which would allow me to plug the fan into a receptical of a floor plug or across the room, rather than to a plug-in about 2.5 feet off the floor. (What idjot guy would build a disco light with a 2 foot cord on it?) If I cut the short plug off of the topaz, and splice or tap the topaz line into the new fan line (which is switched, and has a filter and large capacitor attatched), am I going to require a component to stabilize the power that's going into the topaz device? Just saying... Is there a stabilizer I can use for this?

eh... did I hear sh*ts and g*ggl*s??

The nerve of some people really...I'm glad you said it & not me. My disco lights all have at least a 3-ft cord on it.
Second answer first you making life hard on yourself can't you install an outlet on the ceiling just plug her in.

The system fan is going to create quite a stir in the circuit if its simply unplugged and/or missing.

Same answer.

You overthinking it.,0.00025 Ohms? Now I'm doing that other thing you mentioned while giggling...

Check your local codes where I'm at Los Angeles electrical outlets in the ceiling are considered a junction box so it complies with code your mileage may vary!

Many of those projectors used a ntc resistor in series with the bulb to stop the inrush burning the filament prematurely.
To give you some idea, had a cold circuit dc resistance reading on a bathroom heat lamp the other day.
275w on 240v but the cold resistance was 9 ohm.

I bet you know how to throw a good time.
