A Link To The Past
Whenever Link enters a cave, dungeon or other dark area he will have instant access to his trusty Lamp. The oil in the Lamp is long-lasting, but it does require Magic Power to light."
"Link realizes that if he must go to the depths of Hyrule Castle, he'll need a dependable Lamp."
"Link can always use the Lamp to light the larger, stationary torches in caves and dungeons."
"A Lamp in 3 Locations
If, for some unforeseen reason, Link neglects to collect the Lamp before he leaves his house and enters Hyrule Castle, he can find other Lamps inside the castle. It's best for Link to pick up the Lamp at home because it allows other important items to appear in the Small Chests inside of Hyrule Castle."
The Lamp is the first item acquired in A Link to the Past. It is found right after waking up, in a chest located in the southeast corner of Link's House. With the Lamp, Link can light torches and see in dark places. However, it uses up a small amount of Magic Power. If Link does not take the Lamp from the chest in his house, he instead finds it in the Sewers of Hyrule Castle.
A Link Between Worlds
In A Link Between Worlds, the Lamp makes its second appearance. It functions similarly to the Lamp in A Link To The Past; however, it does not actively utilize the Stamina Gauge, making it infinitely useable. It can be upgraded into the Super Lamp by completing the advanced course of the Treacherous Tower. It becomes incredibly powerful, dealing eight times the power and making it a useful weapon for close up encounters, though other items may still be more efficient to use.
- When merged into a wall, the Lamp is visible attached to Link's Belt. It also continues to give off light around Link.
