I wonder if this should be taken to mean that {tamghay} normally refers only to visible light, rather than the full EM spectrum. Or perhaps it's context-dependent, like it is in English (with the everyday definition being just the visible parts while within many scientific fields it'd be the full spectrum).

Based on the context and the usual meanings of the English glosses, it seems likely that {tamghay} normally means visible light.

Lieven: Roughly speaking, it seems like {wovtaHghach} can be taken to mean "the state of having a lot of {tamghay}". Is this correct?

Did Okrand talk more about the use of {'otlh} for light? Up till now, the use of {'otlh} in paq'batlh was the only time we had a noun for "light" as a phenomenon.
