Do the published numbers agree?

These checks compare figures the manufacturer published against each other. Nothing here is estimated: every operand is a published number and the arithmetic is shown so you can redo it. When a check does not agree, that does not say which figure is wrong — only that they cannot all be right at once.

Not enough published data to check

Average irradiance vs. total optical power ÷ illuminated area

Missing: total optical power, illuminated area, declared irradiance.

⚠️ Numbers do not agree

Claimed runtime vs. battery energy ÷ rated power
