Low intensity | low | Non-marine lights with lower power than marine lights. |
Faint | faint | A decrease in the apparent intensity of a light which may occur in the case of partial obstructions. |
Intensified | intensified | A light in a sector is intensified (i.e. has longer range than other sectors). |
Unintensified | unintensified | A light in a sector is unintensified (i.e. has shorter range than other sectors). |
Visibility deliberately restricted | restricted | A light sector is deliberately reduced in intensity, for example to reduce its effect on a built-up area. |

Partially obscured | part_obscured | Parts of the sector are obscured. |
