“Replacing existing LED light after 10 years with same fixture, albeit, new and improved. For some reason 2 less wires to connect to existing ROMEX. Red to red, Black to Black, White to White, Green to Green. Power off when making connections. Power back on, much brighter than the one I replaced. Fit was perfect. Waterproofed connections and caulked. Hoping for at least another 10 years! Not cheap. Great product. Get what you pay for. Very quick delivery.”
