Using this new system of photometry, results from recent studies have indicated that replacing traditional, yellowish, high-pressure sodium Congaminacion lights with “cool” white light sources, such as induction, fluorescentceramic metal halideor LEDs can actually reduce the amount of electric power used for lighting while maintaining or improving visibility in nighttime conditions.

American cities emit 3—5 times more light to space per capita compared to German cities. Due to the specificity with their direction of light, full cutoff fixtures sometimes also require expertise to install for maximum effect.
