Final answer:
The specific wattage of a light bulb for an NVG test lane is not given, but discussion about light bulb characteristics, efficiency, and temperature-related resistance changes has been provided to illustrate concepts related to light and energy associated with different wattages of light bulbs.
Step-by-step explanation:
The wattage of light bulb used for an NVG (Night Vision Goggles) test lane is not specified in the provided context. However, we can discuss the properties of light and energy as they relate to the question. Incandescent light bulbs convert electrical energy into light and heat energy, but this process is not highly efficient, with only about 10.0% of the energy converted into visible light. For example, if a 100-W incandescent bulb converts 10.0% of its energy output to visible light with an average wavelength of 580 nm, and photons spread out uniformly without atmospheric absorption, we could calculate the visibility range based on photon flux entering the eye's pupil.
Light bulbs with different wattages have different energy consumption rates and light outputs. A 60-W bulb typically has lower resistance but draws more current and uses more energy than a 25-W bulb. On the other hand, compact fluorescent lights (CFLs) can produce the same light intensity as a 60-W incandescent bulb but use significantly less power, between 1/4 to 1/10 of the power.
Resistance and power consumption are also affected by temperature, as seen in the case where a headlight may dissipate 30 W when hot but can draw 411 W when cold due to lower initial resistance that increases as the temperature rises.
