This sort of thing looks pretty useful. Definitely something to consider
for path lighting. A look at them one year in may be in order for
water ingress, corrosion etc. and mitigation of same.
An interesting YT channel I found was bigclivedotcom - often he's
destroying or reverse engineering things; sometimes LED 'ballasts' and
USB power banks in the name of safety. He's a devotee of the small solar
LED garden lights and has done a number of videos on weather hardening
them, which would easily translate to the bigger stuff.
I will be getting some similar to these for around home.
