Yep! over 150 clear 400W mercs still in service! The owner is in for a rude awakening in 2016 though... A lot have vintage photocells too. Photocells that end up broken from getting brittle are replaced with shorting caps or new PCs. The PCs are all bypassed though I think since all the lights come on at the same time and they turn the lights on way before it get's dark. These are 208V 3ph.
These are in the process of being replaced by LEDs. I do not know anything about the LEDs, just that there are LEDs replacing these mercs. Many have already been replaced.
