Need advice on high bay LED fixtures in a very hot boiler room.

[Russs57]

Fixtures would be about 18 feet up. Would estimate temperature at 150 degrees F. Existing are 400 watt metal halide. More light output would be nice. Most important is reliability as many fixtures are hard to get to. Not that I think it would be an issues with LED's but need fast re-strike time in power outages.

Would prefer a "big name brand" like Lithonia. Fixtures don't have to be LED so suggest whatever you think would be best. Able to handle getting sprayed with water a big plus.

Thanks in advance.

I have the 160 watt version in my garage with 16 foot ceilings and I love them. I cant speak to their reliability at 150F but I have had them for about 8 months and so far no issues. (Hyperlite)

This is one of those application areas where discharge lighting still shines. Pun intended. Around an oven 15 years ago we found that quartz halogen lamps held up the longest. Given that they run very hot to start with I’m. not surprised they were highly heat tolerant.
