very much so- most led suppliers will have a datasheet available that lists things like PIV, forward current, etc etc
( heres my streetlight one...)

that tells anyone who knows how to read it everything they need to know about its electrical behaviour
most dcc supplies are dangerously close to the upper limits (eg something like coach lighting can - even with a full rectifier diode bridge be close to them)
even dc supplies can in the right(or wrong) circumstances be enough to be damaging them- even with a series resitor of the correct value fitted
