I just had a 25A "hockey puck" SSR fail in the middle of my show. Luckily I had a spare. I was surprised at this failure though.
It is a 25A 120/240v rated unit. I have max (all white, full brightness) of 20A through it (typically much, much less). I do not have a heat sink in use.
Are these failures common (or not usual)? I wonder if I should go to a 50A rated unit (without heat sink) or add a heat sink to a 25A version. This was not an easy fix (due to enclosure & location) and I would like to prefer a repeat.
