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

Getting just lumens is cheap. Getting a full spectrum of light is where costs increase.
This is the reason I chose to go with the specific Cree bulbs (linked in original post) that get a 90+ CRI rating
