The connections on most any low voltage light is always going to be
damp and conduct a certain amaount of current, be it above or below
water level. My ponds low voltage lights around the shoreline have
routinely been totally submerged in water well over their tops and
burn just fine udner water until the pond water level drops to
normal...There is not enough resistence to make em
short........However excessive current flow can do some strange things
to fish, be it low or high voltage.......

Are you sure they are 24VDC, and not 12 Volt AC. I have never seen any
residential 24VDC lighting, I have seen it in commercial stuff though.
I would stick with the norm and go 24 volts.

If you hneed to spice your wires to your lights and have it water
proof there is a kit made by 3M (Scotch) that you can buy........not
really cheap, about 20 bucks for one 2 conductor lead.........do not
use silicone to "waterproof" your connections as its bound to
fail.....
