LED lumens, lux and other non-standard brightness
How to compare it

"LED lumens" / "light source lumens" / "lux" / "peak lumens" ⚠
Non-standard units, typically 2–10× higher than ISO lumens. "Light source lumens" measures the emitter before the optics. "LED lumens" has no definition at all. We never show these as headline brightness. We store them as brightness.claimed_lumens with brightness.claimed_unit, and on the data sheet we flag "unverified unit".
