Tips on modding Skyray STL-V2

Anyone got good tips for a driver upgrade for skyray stl-V2?

Mine draws 1.5A on high with two batteries and it doesnt get warm at all while using outdoors. Indoors it gets abit warm after 20mins on high when standing on the table. So i thought there could be a chance to put a more powerful driver in it.

What do you recommend? Or do you recommend at all upgrading the driver?

The stl-v2 has really a pretty descent driver..

You could start with doing a allu foil mod (around the led) for squeezing out a few lumens extra.
