More oil needed I think but at what level the oil warning light is switched on?

As above, it's an oil pressure warning. There is no oil level sensor! (well there is, the oil temperature sensor could do that but LR decided not to use it...)

Yes, odd that there is a combined oil level and temperature sensor fitted and whilst the level sensor is not used the temperature sensor is used:

"The oil level and temperature sensor is installed in the cylinder block skirt stiffener, mid-way along the RH (right-hand) side of the engine.
The oil level signal is not used, as a mechanical dip stick is fitted.
The ECM uses the oil temperature signal to control the engine oil temperature. In extreme operation the ECM limits engine torque to prevent the oil temperature exceeding 140 °C (284 °F)."
(from Workshop Manual)

It's interesting that with that much oil missing from the system of the OP's vehicle that the temperature did not exceed the threshold stated and so limited engine torque in a way apparent to the OP; or perhaps it did and OP did not connect the two?

Also begs the question if the level sensor is there why it's not used to give an extra level of protection. If it's engineered into the wrong part of the engine and may give false reading when off road at extreme angles, then surely the temp element of the same sensor would suffer the same issue?
