Still, it emitted enough light to make it day in space.

The animal does not emit light continuously, but can do so for a period of five minutes after suitable stimulation.

The discharge then emits light with wavelengths corresponding to the spectral lines of the metal.

Soon he's emitting light and his weight starts creeping mysteriously toward zero.

This is because the phosphor compounds which emit light to produce images lose their luminance with use.

The lighthouse at initial stage is used to emit light once in 7 minutes.

It emits light just like an ordinary flashlamp, but in a tighter beam.

The transistors can emit light and may have future use in optoelectronics.

Now they were dark shapes, too geometrical to be natural, but emitting no more light than the forest that lay a few hundred yards away.

Not only does an object emit more light as the temperature is increased, but the most probable/likely photons to be emitted also changes.
