Methinks I'm going to buy a couple cases of traffic signal bulbs. 8000-16,000 hours, as opposed to 750-3000 hours. Have a 169 watt bulb in a table lamp here in my room. Came out of a signal head that I got from the City of Bellevue, Washington (yes, legally), in 2002. Installed a LED module in 2004, and figured I'd reuse the bulb for the table lamp. It's still working. May be a bulb from last century.
