Because smoke disperses light, a narrow beam with good throw and very minimal spill is necessary. Spillage causes the iris to adjust to control the light, making it harder to see objects from far away. Additionally, an LED with a lower color temperature will help reduce dispersal. Lower color temperatures have longer wave lengths, so they are reflected less by rain or fog. This means red and yellow-toned LED bulbs are ideal over blue and bright white.
It is important to note that visibility will depend on the density of the smoke. Thinner smoke will allow more penetration of light, but thick black smoke will require thermal imaging.
