Can You Convert Solar Lights To Low Voltage

Some solar lights come with a remote solar panel that connects to the fixtures.
Can you convert solar lights to low voltage. Retrofitting your existing garden lights with led bulbs will deliver four wins. Battery bank you need at least one deep cell battery to power your lights and it should be rated for at least 150 amp hours to allow the system to compensate for cloudy days and to power the inverter. The other two types of lights will deplete the accumulators dc power much. The more charge the battery can hold the longer it will power your lights but keep in mind that a bigger battery needs a bigger solar array to keep it charged.
I wanted to find out if it s practical to convert these to electric with a transformer so i can run them as low voltage. That is why they are used on solar lawn lights. They currently use 2 1 5 volt rechargable batteries and use a single led light bulb. I ve looked everywhere for 12v lights anythi.
You want to lay underground cable to the lights and convert them to 120 volt ac wiring and screw light fixtures. I have some very cool solar lights that are very unique that don t do very well as solar lights due to too many trees providing shade. I want to convert them to a low voltage system and am not sure how to calculate the voltage requirment for these bulbs since they are not rated by. Do i understand correctly.
Led lights consume much less electricity than incandescent of fluorescent lamps. I have used one for light inside my shed before. It is somewhat like low voltage lights without having to have a need for a 110 volt power source. You can place a solar panel where it gets light for power and run the cable to the fixtures.
