What you mean: the battery voltage has dropped 60 mV. If the lightbulb was designed to work on 2.4 V, why would the manufacturer list "(AC 100-240V, 60 Hz)" on the bulb? Being able to use it on 2.4 V DC would be a nice feature. The circuit in the lightbulb need a high voltage of at least 100 V AC. It has to do with how the circuit is deigned.
A 240V AC means that it has a peak voltage nearly equal to. 240 × 2–√ ≈ 340 V 240 × 2 ≈ 340 V. Where the given values for the voltages for AC source is usually the RMS voltage Vrms V r m s, which is defined as the square root of the mean square of the value of the voltage across one periodic time Wiki, and it is related to the peak

DC-to-AC converters (add grid AC-to-DC also) can be used but I wouldn’t be surprised to see USB ports directly on the battery for charging things. The reason we have 120V / 240V systems is
Product Description. The AIMS Power 5000 watt inverter with 240 volts AC output is a great choice for an off grid well pump that requires 240V ac to operate. However, keep in mind that this inverter is not a "split phase" 240V ac; you will not be able to pull one leg off to create 120V ac. The 240V ac supply is accomplished through one of the
