Lumens do not stack.

That means if those LEDs are 200 lumen LEDs, the most you're actually getting is 200 lumens.

Photon flux density is a different story.

pic related - I build and design lights. Don't get fooled by bullshit marketing.

Never have, never will.

Prototype on breadboard, finalize on CAD.

Otherwise, prepare for expensive failures.

Pic related - the most powerful diode array on the planet right now, made specifically for horticulture. 300w in a 30mm x 30mm package.

I made this. If I hadn't made prototypes, I'd have never gotten even this far.
