===Effect===
If the Pokémon holding this item creates [[harsh sunlight]] with the [[move]]s {{m|Sunny Day}} or {{m|Max Flare}}, or the [[Ability|Abilities]] {{a|Drought}} or {{a|Orichalcum Pulse}}, it lasts eight turns instead of five turns. (Prior to [[Generation VI]], it has no effect on Drought, which creates harsh sunlight with indefinite length in those games.)

In the [[Generation VII]] games, if harsh sunlight has its duration extended by the Heat Rock, the turn counter on the user interface for these effects will indicate that it lasts for 8 turns for the player whose Pokémon used the move, while it will display that it lasts for 5 turns for their opponent. After 5 turns of harsh sunlight have passed, the user interface will display that it lasts for 8 turns for both players.
