The head can be rotated 270?, allowing the light to be directed where required, and it can cast a wash of light upwards, downwards or to either side. Worth Knowing To create a more innovative look, this light has been designed to incorporate the LED within it. This LED is not replaceable but has a lifespan of up to 20,000 hours. LEDs use around 85% less energy than incandescent bulbs.
