Of course, all sodium lamps appear orange - amber for most people. I'm talking about the ones with an orange coating on them.
I've seen Rommie's
Amber glassed SO/H, supposed as a darkroom safelight.
I've seen Max's
SOI safelightBut this is a new one. On Ebay I've just found a Philips 35 watt SOX lamp with an orange coating. The seller claims it was intended for TV high masts / tall buildings for a warning light (like the red aviation beacons). I have attached an image below. Does anyone have some insight on this? Is it just another safelight or is it genuinely a safety light?
