Quote - Here are my FireFly SUPERFAST Manual Settings:

• All checkboxes turned off.
• Min shading rate: 5.0
• Pixel samples: 1
• Max texture size: 1024
• Max bucket size: 64
• Min displacement bounds: 0
• Post filter size: 1

At these settings, I can see what my lights are doing just fine. The above render was made in 3 seconds.

 

Actually if your machine can handle it, I find increasing the bucket size to 256 or even 512
gives a faster render.  At 1024 my machine chokes, but somebody with a faster machine
and more memory might even want to give that a try.
