    Default Leigh Lights

    Hello,
    Were Leigh Lights ever fitted in pairs on aircraft ?
    In another website it refers to a book(no title given) that suggests that they were and used over the Atlantic.
    If the RAF didn't, perhaps the US did ?

    The Leigh Light was a very heavy and draggy installation, largely because of the battery requirements and the technology of the time. Two of them would have been an encumbrance: what would the purpose of such an installation be?

    Thanks Graham, my thoughts as well.
    If they were both connected to the same power unit, they would surely not be of much use.

    I think the whole setup had to be designed based around fuel/endurance versus weight/drag of the Leigh light installation. Given the known demands on the aircraft thus equipped, it would not take long to decide the best balance between reasonable fuel/weapons load (including the light and its batteries) and desired endurance. Thus simply comes down to very pragmatic in the so-called "Battle of the Atlantic", which was really an entire war in its own right.

    Hi all, I can confirm the RAF aircraft used only one as far as I know. The LL has been installed on later 311 Sq Liberators and it was possible to drop it if the Liberator was in trouble. But for example RAF Catalinas were not able to drop it.

    I'm pretty certain in the case of the Liberator, the engine driven generators on the aircraft would have been more than capable of producing real-time demands for a single Leigh Light. The Fortress had 4 X 200 amp 24 volt generators. That's 4800 watts each. THAT...is a lot. The Liberator likely had similar capacity.
