I needed a sensor light to replace a failed old colonial design sensor light. It was important to find something very similar in appearance, as our old light also activated a separate passive colonial light nearby. The Duanera light is made of weather-resistant plastic and is easy to assemble by following the pictorial instructions. The hidden time and sensitivity adjusters are accessible by rotating the "eyelid" of the sensor. My old unit had been professionally wired so that it could also be manually turned on if necessary (overriding the sensor) and was also wired to a second passive light. The wiring requirements on the new light were compatible with what I already had in place, so it was an easy case of 'plug & play". I am very happy with the appearance, design and quality of this product.
