For Trainspotting 2, we was given 2 Weeks to design and build a custom LED light to mount on a Russian Arm. with the ability to remotely control from the vehicle.
Based on the requirements and the time available, we decided to repurpose an existing LED fixture, which has a high CRI rating.
This gave the DOP full colour control, with Red, Green, Blue, Tungsten & Daylight emitters.
A new housing was custom built, which made use of air cooling generated while driving, allowing us to remove the weight of the heatsinks, while retaining the output of the LEDs.
To further reduce the weight of the fixture, we located the power supplies at the base of the Russian Arm, in total reducing the total weight from 6kg to 0.5kg.
