I haven't had any explode, though I have had a few fail in a weird way. Instead of lighting or going dark they blink. This was a couple of heavy, bright spots with big, beautiful heat sinks out of a larger group of 12. A friendly agency loaned us an extension lift and I replaced all of them, blinkers and steadies both, with new, cheap TCP brand from Home Depot.
The brand on the old ones escapes me. I saved the ones that are still good for re-use in more accessible areas. I'll find out and post it here.
