My stoopidvisor bought a large quantity of the first gen LEDs for the rock farm. I think he was more interested in the sales rep than he was in the light bulbs, she was very attractive :D . The asphalt plant I operated has a 600' long tunnel to provide 5 different materials for the different kinds of black top. It's dark in there 24/7. The tunnel was made with railroad tank cars welded end to end :wtf:. It makes sense if ya think about it :realcrazy:. Those LEDs projected one little bright spot on the opposite side of the tunnel and did nothing to light the work area and only lasted 90 days maybe. Being inspected by 2 OSHAs the lighting had to be protected just like a mine, glass enclosure with a protective metal cage over that. Those cages were 9"? deep so most anyting would fit in there. I found that the screw in flourescents had the longest life span some as long as 5 years. What can I say? When I was the oiler/fireman I had some time on my hands and soapstone in my pocket. When I replaced a bulb I put the date on the tunnel wall :lol:.
