Help needed - I'd like to run some mains powered led lights from battery instead and control remotely?
Here's a bit of background to the project I'm trying to undertake. My wife and I recently got married and as we met many years ago working on a cruise ship, my family decided to commission a model builder to build a replica of the ship we met on. Wonderful! We've mounted it on a shelf on the wall half way up our stairs as it's the only place in the house it fits. My only problem is that is has a set of lovely white led lights built into it with a cable coming out with a plug on the end. There's no easy and elegant solution to get power to the shelf where the ship is and I can't access the lights to swap them for a battery powered set as they're sealed within the model. I figured that it may be possible to create a battery pack to connect to the lights instead of the plug. As they're leds, I assumed (and we all know what that leads to) that they may be low powered enough to run off batteries.
The other thing i'd really like and i have no idea if this is even possible, is to to have them turned on and off remotely as reaching the shelf to switch them off will be quite tricky as it's very high up.
I don't have the first clue where to start. I am attaching (if I can work out how to do it) a picture of the plug that I have removed from the lights to hopefully give someone a clue as to the power requirements of the lights.
Any and all help would be greatly appreciated.
Thanks again in advance.
