If you mean light that escapes from poorly directed lighting units, and so is not useful to us, it gets absorbed in surrounding structures, vegetation, trees, etc, and ultimately in dust in the atmosphere.

If the grass is at the base of the energy pyramid and 90% of the energy is lost at each trophic level, the amount of energy available for the hawk would be 10% of the 10,000 units, which equals 1,000 units of energy.
The energy that is lost when an electron falls to a lower state is emitted as a photon of light. This process is known as photon emission, and the energy of the emitted photon corresponds to the energy difference between the initial and final states of the electron.
10% of energy is lost as you move from 1 level to the next. So at the end 90% if the energy will be lost as heat.
Energy lost by an electron during its transition from an outer to an inner orbit is emitted as a flash of light called an emission. Light/energy emissions are released in a characteristic manner (wavelength) that corresponds to the amount of energy lost.
A third-level consumer can use roughly 0.1 units of energy from the original 1000 units produced by the producer. As energy is transferred through trophic levels, only about 10% is typically passed on, with much being lost as metabolic heat or used for the organism's own functions.
Some energy is changed to heat and lost. The main energy is still be converted to light beam.
When you turn on an electric lamp, electrical energy is converted into light energy and heat energy. The electrical energy flows through the lamp's filament, causing it to heat up and emit light. Some energy is also lost as heat due to resistance in the lamp's circuit.
The Momentum from each of the objects colliding is added together, and the collision follows a course based on the sum.Example:Object A is going 25 (Units) SouthObject B is going 20 (Units) NorthEnd Result: 5 Units SouthThe Energy from each of the objects is transferred to sound, light(sometimes), heat, and mechanical energy.
