convert solar-powered sensor light to low-voltage ??

Hello, I am not an electronics expert, but I am wondering if the following is possible ( and how ).

I see a number of solar-powered outdoor lights with motion-detectors ( such as those made by SunForce ). Can they be "cheaply" converted to run off low voltage lines instead of solar-battery ?? I have a number of low-voltage outdoor garden lights now, and would like to run the motion-sensor light off that same low voltage line. The market does not seem to make "low voltage" motion-sensor lights...

I appreciate any feedback and advice offered by your team !

You have them on eBay. The less expensive ones are rechargeable through USB and some more expensive with solar pannels. Search for "light with motion sensor", you should find without problem. I have tried one some time ago, they were really power hungry, relatively speaking though, back then. Many of these devices seem ecologicaly friendly at first glance, but they are terrible, energy wise, overall. EEVblog, on YouTube, blasts many of them.
