The streets of LA have undergone the world’s biggest LED street light revamp, which have seen them go from a bright yellow to a sophisticated white. Films shot before this change will feature the orangey glow of the lights and as Dave Kendricksen said: “In a sense, every night exterior LA-shot film previous to this change is rendered a sort of anthropological artifact, an historical document of obsolete urban infrastructure.” He also added: “The [new] LEDs should very well prove a benefit to existing-light photography – better for the environment, and in nearly every case better for cinematography.”

Though this change may have raised mixed views among filmmakers there is a vast improvement in terms of economic and ecological values. Justin Gerdes, who writes for Forbes, states that LA are expecting to save $7 million in electricity bills and $2.5 million in maintenance costs. The bulb’s life expectancy is between 80,000 and 150,000 hours as well as producing 42 to 81 lumens per watt.

So next time you’re watching a new Hollywood film, see if you can spot the difference.
