This light was quickly installed as a replacement for a different solar light that was old and not working well.  The level of brightness of this light is quite good.  It lights up the base of my driveway nicely.  I don't quite know yet how long it shines after dark as I haven't checked on it ... but so far I do like it.  If the light stays on for quite awhile then this will actually be a 5 star review.
