My subdivision has gates with 2 post lights, each with 2 mini candelabra base bulbs, plus 2 150 watt floods (tube type lamp) on the sign. The post lights each used 2 60 watt incandescent lamp. We were changing one lamp every few months. So, I though, LEDs. I bought a single LED flood fixture, with 2 20 watt LED patch arrays and appropriate electronics to drive them ... about $40. For the lamp posts, I used 5 watt frosted LED flame shaped bulbs from Lowe's.
This was September of 2013. So far, the flood is still ok, with the exception of some physical damage either by an animal or a 2 legged animal. I really think it was a bear or deer foraging around for some food, because if a person wanted to break it, it would have been really broken. And it looked like it was just bumped really hard. Out of the
6 LED bulbs, one failed after about 2 weeks ... replaced by Lowe's. Last week, another failed ... Lowe's also replaced it. These are supposed to have 25000 hour lives, however, by my estimate, that one only lasted about 2400 hours; maybe only 1/10 of the estimated lives. Anyway, the test goes on. As long as Lowe's stands behind them, I'll keep replacing them. And, actually, if they had lasted 10,000 or 15,000 hours, I probably wouldn't have said anything. The service rate is still less than the old bulbs. I would have loved to dissect the bulb and find out if the electronics or the LED failed. Unfortunately, I had to surrender it to Lowe's. My money would be on the electronics and not the LED itself.
