I have purchased from Sunny Bunny before and as expected, quality is excellent. I have these lights setup to light up pathways and stairs around the house. When the movement sensor is activated they switch from dim to full power.. and boy are they bright! The only mod I have done is to use a taller post so I could mount them higher. I used an old Black paint roller extension pole because the diameter was a perfect fit into the base of the light. Then I screw fixed the lights to the pole
The advantages of the dual spotlight re the ability to light two different areas with flexibility in both horizontal and vertical directions. I have placed the light on a old broom handle to give some height and the ability to move the unit around. Need to give some thought to placement so that the sensor is effective.
