Is it possible you got the 220v bulbs? Maybe @mauricem00 could give his thoughts. That would be too bad if they're really not ~105 lm/w. I haven't received mine yet.
This is the thread you're remembering: https://www.rollitup.org/t/t8-lights-for-growing.850807/#post-11056855

There's no markings on the bulbs themselves but each box is marked 110v, so that's all I have to go by. Thanks for the links to those threads by the way.
