I need to buy 2 LED floodlights for the back garden and driveway:
The garden is 15m(49 feet) long.
The driveway is 13m(42 feet) long.
I can't seem to find an answer online as to which wattage I should get. I want both areas to be pretty well lit. At the minute I'm leaning towards a 30w LED such as this one: https://www.amazon.co.uk/Equivalent-Daylight-Waterproof-Security-Floodlight/dp/B016VS0ZNQ/ref=cm_cr_arp_d_product_top?ie=UTF8
But I'm wondering if I should go for a 50 for the back garden.
There are no houses in front of me so I won't be disturbing neighbors. There's also a large fence at the back, so again, it shud'nt bother the neighbors.
Any input would be appreciated.
p.s. can the light listed above be turned permanently on and off by a switch? So the sensor is active always however you can turn it on permanently if you know your going to be outside for a longer period of time? I'm guessing it cant?
