[SBE] LED tower lighting

[A9xw at cs.com]

We have strobes. They lasted 20 years with 3 failures (other than flash 
bulbs) then a hit on the utility line took out the entire system.  We replaced it 
at a mighty big cost. The new fixtures are plastic not glass/stainless. A 
lightning strike took out two side strobes and locked one in daylight mode really 
annoying the neighbors.  We've been waiting 5 weeks for the crew to return with 
parts to fix the two day only mode fixtures, the controller, and 1 crispy 
fixture.  So much for Flashtek. Apparently no spare parts on hand since 
Dielectric took over.  We had a regular maintenance once every 2 years to replace flash 
lamps with the original system.  Even a lightning strike that caused the 
Bogner antenna to arc over and melt that burned the 480 V power lines in the 
conduit didn't damage the old strobe fixtures. I have 3 tower levels and 1 top at 
1008' in the middle of corn fields, suburban sprawl and 35 miles from the 
closest tall structures in downtown Chicago.
