The LED recessed lights were selected by our electrical contractor and, while they perform well from a lighting standpoint, several of them have now failed from a staying-intact standpoint.  Five of them have fallen apart, the most recent being a surprise when we heard a crashing sound in the kitchen.  The problem is that the trim breaks free from the rest of the housing, falling to the floor.  The electrical contractor is no longer in business, having been acquired by another firm, and I thought that rather than complain I'd learn how to fix them.  It's not that hard, but I'll know better next time and will avoid specifying Halco ProLEDs on future projects!
