12.00 Volts to 10.00 Volts LED Bucker
Never a dull moment. Genuine 10 watt LED chips (they need a heatsink) are not 12.00 volts capable. Driven much higher than 10.00 volts, light output stays the same but heat increases as dramaticall...

If your LED (array) is bare, that is, no other electronics involved, then you can put voltage aside and only worry about current, since LEDs are current mode devices.
On china-e-bay, there are plenty of adjustable constant-current LED drivers. If your delta-v is very small, a SEPIC type driver might be the best fit, as it allows input voltage to be higher or lower than output voltage.
350mA SEPIC driver
700mA SEPIC driver
