    I have 3 LED's which I need to build drivers for.

    1. 3500mA 30-34 Volts
    2.700mA 30 - 34 Volts
    3 1050mA 30 -34 Volts

    I was Going to use a constant voltage power supply, but now I need to add the LED driver. The mean Well range offer a 700mA and a 1000mA but have no idea what to use for the 3500mA

    LEDs would be better driven with a constant-current supply.

    The meanwell HLG-120H-36 series is 3400mA @ 18-36VDC

    The Meanwell units list for $60+USD. Try some of the units direct from Chinese manufacturers, available for less than $10USD. Some examples are at LED World via their ebay store at http://stores.ebay.com/ledworld2010professionalleds?_trksid=p2047675.l2563
    Make sure the unit you get has overload protection. Many of the cheaper units will instantly overvolt & burn themselves out if there's no adequate load on the output.

    Meanwell never replied to my email. Possibly because the volume of my needs is very small
