We have the Enbrighten puck lights around our pond and they're awesome. I've purchased several LEDs for the pond/garden over the years, but these Enbrightens are the best. However, they come in 6 pack and may be overkill depending on your size.

There are some weatherproof LED lamps with remotes on Amazon for $16. I bought these originally, but needed more lights on a single strand. https://www.amazon.com/gp/product/B071NDG8TH/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

We have some flame bulbs as well, but those are better suited for Halloween, in my opinion.
