MTH Floodlight - what's the highest voltage they'll handle?

Neal, I have a set as well. They are wired into a bank of other lights on my layout so I have to limit the voltage to 16V - 18V making these towers way too dim for my service yard.  They look fine at 20V, but it’s not good for the longevity of the other lights. I’d be interested in others’ input on a way to brighten them up?  Is there a good replacement bulb out there?

I assume these take a single bulb the illustration isn’t that clear. You could go with a 18V LED replacement bulb and not have to worry about bumping up the voltage as the will run much cooler than incandescent bulbs. Town & Country or Hennings has  replacement  LED bulbs. 

Thanks guys. I feel stupid even asking the question since this is model railroading 101, but just wanted to know what other's experiences have been. It's like they used 24 volt bulbs these things, and they should be bright, not dim!

Here is an LED upgrade post on those towers.

Thanks Dave for the link, I’ll check it out.  The bulbs are usual and there’s not a lot of room for anything too different.  I’ve attached photos.

220v, 221v, whatever it takes.

I don’t think there is a LED replacement for that style. 

How are they are wired series or parallel ?

that could make a difference.
