Hi,

If you can get under the ice it is possible yes. Is the rink inside and using
a mechanical freezing system? If so the heat from the lamps shouldn't affect it
or melt it. I have seen ice carvings lit up and the colored lights really made
them beautiful. I wouldn't put the lamps too close to the ice if you use
anything over 40 watts. Make sure they are waterproof exterior fixtures with a
GFCI circuit breaker feeding them. I like the idea you want to try.
