Just been watching the mens synchronized diving, and there was a (...) up on the Mexican teams dive, the top camera shot show a powerful LED flood switch on just above the divers, just as they started moving forward on the board, the divers claimed it put them off, and asked for a re-dive.
The dive was granted, but as they both got on the board, the judges decided there was to be no re-dive!
It went on for a good 8 minutes!, and the team coach wasn`t happy!, the flood must have been on a cell or something as it was going dark in Rio, but it was an instant `on` powerful beam, so it must have been LED!
