These are in a space that’s being turned into offices. I don’t know what this was before but it’s been like this for years. It’s very cool and unusual. The mercs are 400w and the incandescent are 150W

Before the popularity of MH, and sometimes as a less expensive option, facilities used a combination of MV and incandescent. The gym at my university was lit like that and was built in 1974. In 1976, they built the pool and it was lit with MH.

Nice to see!

Good quality things are awesome. Cheaply made things are not.

From what I understand This area had little rooms in it which were removed and from what I’m seeing here this (“may”) have been there all that time even being switched on and off with the lighting, who knows? It’s possible that these could have been lit 24/7 for the past unknown amount of time.

The incandescent lamps would have certainly burned out long ago if ran 24/7. Even if switched on and off with the lighting on the faux ceiling that was in the little rooms, I'm thinking the incandescent lamps wouldn't have lasted all this time. Very cool they were left in place though, and hopefully some of these will be saved by someone. They lok practically new!

Please check out my newly-updated website! McCann Lighting Company is where my street light collection is displayed in detail.

Ever see a swimming pool area lit with HPS? I have around 1996 a school I went to had an Olympic sized swimming pool and at night it was lit with HPS. That was the first time and the last time I saw something like that.

The gym was lit with standard metal halide lamps the fixtures resembled the canopy fixtures that were used (before all of this LED junk started) to light gas stations but the fixture was recessed into a drop ceiling with a sag lens they probably 400W, but I was not into lighting back then so I am going from what I know now and what I remember from back in 1996
