If I have an LED lamp which is specified as, say, 350 mA at 12 V DC. What would happen if I fed it directly from a 48 V DC constant-current power supply capable of providing up to 350 mA?

I understand increasing the voltage on an LED lamp typically makes it run hotter as it tries to draw more current, but since it is fed by a current limited source is this issue voided?

Edit: I am talking about higher-powered LED' lamps, like ones used for outdoor lighting such as streetlights, garden lights, etc. Say a max. wattage of 30 W.

If I have an LED which gives specification for say 350mA at 12VDC - what would happen if I fed it directly from a 48VDC constant current power supply providing 350mA?
