not unique. But, with the drivers and fixtures needed, not exactly what a homeowner needs for a couple of antique lamps. I've seen extraordinary lumen output in the lab, too, but first there are those industrial new builds, then refits and later come the homes.

As far as the calculations for 30,000 hours go-- you do realize that's about 7 years at a 50% duty cycle. And to compare 9W with 6.5W without a lumen count is deceptive, but even if they are the same output, 20 bucks over 7 years approaches meaningless. I probably should ask what "4.28 $29.66" means, but doubt it will change anything.
