I bought a solar light in Dealz recently. One of those pencil like ones. It cost I think €1.50. There was no sticker you pull away from the battery (?). The battery is encased and not changeable. A very simple solar light. I managed to get it to work. You turn the switch on and stick it in the ground. I was delighted to see it shining away.
But later on, there was no light. It must have lasted only a few hours. I am not sure how long.
So what is the story with this? This is summer and if it is all day in the light outside and lasts only a short few hours, is that it? I mean what's the point of them? Why is it lasting such a short time? If I wanted a solar light to last longer (as in all night which is what I though they would be doing) what should I be looking for? Does it depend on the battery size and if so what should I be looking for?
