I currently am running these same lights, and had S1s back there previously. The Rigids look a lot better, and SPVs wiring kit makes it really nice, but the S1s absolutely put out more light. With the Rigid, it really only helps when using the backup camera. If I look at the back myself, I don't really notice they are on. With the S1s, not only could I see it without camera, but the neighbor across the street could see it in his kitchen.
The BD lights ABSOLUTELY throw out more light. Wish I had gotten them in the first place. I will replace the Rigids with BD soon. Then put the Rigids on the OBS when I can find one at a reasonable price.
