Yeah, for the price it's certainly worth giving the drivers a shot, they can always be used elsewhere. If you're looking to up light trees, there are 10 watt LED floods available that run on 12 VDC. You can also get them as AC voltage models, using household power. They're waterproof & made for the outdoors, you don't need an extra driver since it's built in. My DIY 10 watt multichip aquarium fixture uses all 10 watt LEDs hooked up in parallel supplied by two 12 VDC power supplies & manual dimmers. One of the reasons I chose the 10 watt multichip LEDs is the forward voltage for most of them is in the 9 to 12 VDC range, making it easy to find power supplies. I realize constant current drivers would be safer, but the fixture has been running for close to two years with no burn outs (I'm underdriving the LEDs, keeping voltage below 9VDC through the dimmers).

Check it out, might another option or supplement. Like you said, maximum flexibility. These can be had on eBay as well, just happened to find the link below useful due to the info & description.
