20W Led Video lights advice

[Sharkbus]

Hi there,

I've bought some 20W LED modules,

DC Forward Voltage13.5-15 VDC
DC Forward Current 1400mA-1800mA
140degree viewing angle
5500K, 1000LM

I would like to have a dimmable or 5 step power output.

I would also like to have a burn time of 2hours at full power.

Anyone know of an of the shelf dimmable driver to suit this application? or a kit?

I would prefer to fit batteries and driver in the light-head rather than a cannister.

Cheers
