Illumination

A small, naked bulb gave the only illumination.

Can I ask for an illumination?

Moonlight was the only illumination.

Insufficient illumination is deleterious to ocular health.

There have been inroads against ever growing urban illumination. The International Dark Sky Association in Tucson, Arizona, a group that claims 3,600 members in more than 70 countries, says efforts to curb excess light are under way from the Australian Outback to Britain's Sherwood Forest. In the Czech Republic, an anti-air pollution law also fights light pollution by requiring shielded fixtures to block upward beams. Laws have also been enacted in Chile, thanks to persuasive astronomers who staff the three big observatories there.

They provide wide-beam illumination, lighting a small room or an area in a clinic.

When we went fishing with my father, we always took a lantern with us for illumination when night fell.

The physicists believe the technology could have a range of applications in small devices, including hair removal, laser printing, night-time surveillance and the illumination of delicate surgery inside the body.

Efforts to curb excess illumination are also underway from the Australian Outback to Britain's Sherwood Forest. The Czech law resembles one enacted in Italy's Lombardy region after 25,000 citizens petitioned against obtrusive outdoor lighting.

I bring illumination to the world.
