I have a box of 75W bulbs here; it says 1170 lumens.
When I remember I'll check the 60W box.

Wait--this is the Internet...lessee...I can put in
1170 lumens, and...yep, here it is... 60W= 820 lumens.

(Buoyed by that success, I go back and search on lumens/
candela...presto! )

..."multiply Candela by 12.57 (4pi) to get Lumen"...

Assuming the LED is spherical (which it ain't...)
