    Folks,

    Need constant current supplies around 3A, voltage range to be tolerated
    should be 16V-21V or wider, outdoors, weatherproof, UL. The Meanwell
    HSG-70-24 is a few volts higher than we need but would have worked nicely:

    The problem with them is sluggish to no responses from the factory and 7
    week lead time mentioned at the few distributors there are. That's no
    good because we need several hundred by latest end of April.

    Does anyone know other sources? Probably from the direct LED drive
    market. Should not be much over $50 in 1k qties.

    Guys, nevermind, miraculously I found a source that has much bigger ones
    in stock:

    We'll just use oversized units for a while.

    We could not get help there. But at TRC we did, hoping that a couple
    hundred units from them are enough to tide us over the leadtime until
    new ones arrive.
