Years ago, there was an HN article "You Need More Lumens"[1], which in turn led me down a rabbit hole.
I ended up purchasing:
4 standard table lamps from Target,
28 2000-lumen Cree LEDs bulbs[2] and,
4 7-way splitters[3].
The end result is somewhere around 56,000 lumens. And I LOVE it. Makes me much happier in my home office, especially in the winter months.[1] >>10957614
In my office I have 6 of these, for a total of around 13,000 lumens. It effectively 6x'd my light output for around $150. Worked wonders, especially in the PNW winter.
