In theory, solar powered lights seem like a great idea, but I'm wondering how long they stay lit for.
I work for a company that has looked into these things for garden use as decorations and they work great. The light comes on when the solar panel stops charging the battery - i.e. when it's starts to get dark.
The only problem is, even during summer, with a full day of sunshine, the charge is not enough to keep them running throughout the night.
I guess these versions may have better solar panels, batteries and or more efficient LEDs, but surely the time of year they will be most needed is the time of year they will be receiving the least amount of charge (Winter). I'm sure it'll be enough to satisfy the 9-5 commutyclist, but anyone expecting them to still be lit later in the evening may be disappointed.
It will be interesting to see how they fair come November - which is probably why they've been installed now!
