Want to get some decent outdoor lights. Auto day light switching and solar powered ideally but otherwise 12v as the run will be up to 100yds with 5-10 lights on it

I've seen some outdoor leds which were very weedy . Give out very little light So what spec would I be looking for ? No of leds? Wattage ?And wht duration could I expect on a winters night where it is dark from 17:00 to 08:00

Thanks in advance for all info
