Can You Convert Solar Lights To Low Voltage

I have some really durable solar lights that i purchased but do not like the short duration of lighting provided.
Can you convert solar lights to low voltage. 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. 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. 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.
Retrofitting your existing garden lights with led bulbs will deliver four wins. The other two types of lights will deplete the accumulators dc power much. You can place a solar panel where it gets light for power and run the cable to the fixtures. 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.
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. Led bulbs use a lot less power meaning you can run many more. Led lights consume much less electricity than incandescent of fluorescent lamps. Do i understand correctly.
The benefits of led conversion. Some solar lights come with a remote solar panel that connects to the fixtures. It is somewhat like low voltage lights without having to have a need for a 110 volt power source. 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.
