outdoor lighting

We have visitors coming next week to celebrate my birthday. Tomorrow is my birthday but since it’s Sunday, we can’t celebrate it because most of my friends will go to church. So, I have decided to celebrate my birthday on Saturday. I need to an outdoor lighting into my patio and porch because we will have a barbecue outside the house. I will celebrate my birthday from 4pm to 9pm I guess. Definitely, we will need a light.
