The official Maglite LED upgrade module, with focusing beam. Upgrades any 3 cell C or D Maglite torch to a powerful white LED beam. Unlike 'LED refits' that are not made or approved by Maglite, this is engineered and factory-authorised by Maglite. Its use cannot void the warranty on your Maglite torch. LED technology dramatically preserves battery life, saving you money. It is also more durable as LEDs are virtually indestructible in normal use, and can last up to 100,000 hours. This means no bulb changes. Instructions included.
