I bought 24 bulbs (4 boxes) 10 months ago and installed 22 in my landscape lighting system. This system works about 4-5 hours a day and has hermetic fasteners. I had a blown bulb in the first month (typical electronic bath curve) and haven't had any failures since. Performance was good enough, I bought a 5th box for parts. MUCH cheaper than the bulbs sold by my lighting supplier (Volt Lighting). I'll try to remind myself to update when I get to the other side of the curve of the tub.
