OK, question for ya...
Why do you need them to be on all night until morning? Just a curiousity to me.
I have a dozen solar lawn lights, that when fully charged will last until dawn, but since they reside at the edge of treed areas, lose their total charge and now usually last only 6 hours or so. For me, that is no problem since I'm long in bed before then and could care less if anyone sees them at 4 or 5 in the morning.
However, consider these options:
- You can get 1250 or 2500 mA rechargeable batteries to replace the (I'm guessing based on mine) approximately 900 mA rechargeables in there now. They will last longer and burn brighter.
- Or you can buy another set of the rechargeable batteries cheaply at someplace like Harbor Freight. I believe they are on sale right now for something like $2.49 a 4-pack right now. Then swap them out every once in a while. It'* really quite quick to do and works well enough.
- Or you can look around and find complete low-voltage sets new or used for very reasonable prices if that is your wont.
I personally am so much more in favor of the solar ones as I no longer have to dig things up to bury wires or worry about cutting them, or worry about poor contact at the connections, etc. All things I had to mess with when I had low-voltage A/C lamps.
