Led-spotlights part of the friction problem solution

During Boulder World Cup finals, normally each boulder are lighten up by a spotlight just few minutes before the first person enters. Then the holds are in constant spotlight and get continuously warmed up for some 24 minutes. This means that the conditions deteriorate minute by minute which make the last climber, the winner of the semi, face the worst friction. It should be noted that in the Olympic finals with eight climbers, the last climber face holds that have been in the spotlight for some 32 minutes. The simple solution to get more fair conditions during the finals is to use led-spotlights.
