I need some #12 wire rated 125 degrees centigrade to use as supply conductors for inground Hadco 175 watt MH uplights for lighting a flagpole.They need to be rated for wet location for the inground application.

What should I ask for at the suppy house?

I also need to feed some MH wall floods by Hubbell with the same temp. rated wire.

What wire do I need?

Is this something new in the industry. I would use 90C wire in the past to feed these fixtures...
