James, we haven't had them all that long. One is rarely turned on at all and the other is turned on, always on the brightest setting, every day by 7 a.m. and is left on at least 12 hours a day, sometimes 16 hours. But so far, we're quite happy with them.
OSRAM 60, what? LED, CFL, incandescent? You have a more expensive opener than my Model 3280M, but the manual for the 8550 says to use incandescent or CFL, but "DO NOT use LED bulbs as they may reduce the range or performance of your remote control(s)." But since it says "may" reduce, not that it's sure to, LED may be good. And CFL, halogen are also acceptable in the 8550 while the manual for my 3280M says "Use ONLY incandescent." But I didn't get the manual out and read that until AFTER I tried the LEDs.:laughing:
