Here is the yardblaster once again except this time there is a coated mercury vapor bulb instead of a clear one. This one happens to be a Tungsram bulb. I believe it is from the 80's. This is to show the ways in which the coated bulb is different from the clear ones I had shown before. Particularly the pink warm up tone and the slightly cooler temperature that made touching the bulb bearable. Enjoy!
