The Menards UFO scene requires 4.5 volts DC. I have 5 volts all around the layout. Can I use that with a diode drop, which would give me about 4.3 volts for the UFO, or would that cause problems?

Should work fine, but being a chicken, I would put two diodes in series first, then measure voltage from diodes to UFO. Diode drops vary between .2 and .7.
The power supplies that I bought from Menards specially to run the lights in their buildings measures 11.5 output? And that is after I returned the ones that they said were too high and got new ones?

Chugman: Question for you,, do you have the transformer that's slim line, like what the new ones show on the website or the old boxey looking transformer? That would make a difference. just asking...Bob
Is that 11.5 with a load, or not connected?
This is the supply Menards recommends for the UFO, 4.5volts:

has anyone taken a current measurement/voltage measurement when the display is running?
With this I would look for a regulated power brick at a the 4.5 volts and try to get more amperage then needed, as the unit will only draw what is needed
Sorry, but perhaps my intention was not clear. I would like to tap off of the 5 volts I already have around the layout. I would prefer not to run a 110V AC line to the area where the UFO will be placed.
MED's reply pretty much answers your question. The diode method should work fine. I have done the same thing to operate animated signs.

Just make sure the Diode will handle the current draw
