There is indeed such thing as a water-safe power supply! Typically anything rated IP6X is fine, often you can get away with IP5X.
I’d be happy to recommend some, (external LED drivers often include dimming solutions, you are wise to want something other than a resistor!), I just had one questions first.
Are these LED lights? I’m assuming, given the low wattage and restriction on other light types, that they are. Better safe than sorry though!
Those are some lovely bulbs. You definitely want to go with a supply with an IP rating, some may not have this so you don’t know if its been tested.
The first digit though is for solids. For liquids, it’s the second digit you care about. You can read up a bit more here about the IP code. Ratings can often be found in a products datasheet. We can have a look if something of ours that you are interested in doesn’t have one.
Nothing if you don’t want it to last long.
depends of course on what sort of current is required to light these globes to an acceptable level. To date no one has mentioned this.

If it is one of those little block 9V types and the globes need a fair bit of current the battery will probably die before you get anywhere. But try, you never know and all you can do is bugger up a battery.
Use your multimeter on the 10A range.

I looked into a lot of waterproof systems but the problem I couldn’t solve is where can I put the cable such that it would be a tripping hazard.
In the end, I what worked great was just a good ol’ 9v battery. Way brighter.
Current draw on the hole thing was about 250ma so a 9v Battery should get me 4 hours of light.
That’s not super impressive but it’s actually all I need, I’m not out there all the time and a 9v battery is easy to plug in and take out.
