I found this website from a previous message and found this to be the best place to buy any LED bulbs, motion detector fixtures and accessories.
Worth marking as a favorite for anyone wanting to upgrade to LED without the Camping World high cost.
LED Lights for RV Website
They charge for shipping but it is really reasonable.
I just replaced my porch light with a black motion detector light.
It comes with a 200 lumin led light bulb but you can upgrade to a 300 easily.
