Yes it is made from mostly plastic but it is a good quality product. The sensor has better all round range than my previous aluminium security light and is also tilt adjustable. The only thing perhaps slightly confusing at first is the live wire colouring. Its not our usual brown (uk) but black that needs connecting from the lamp and of course it doesnt need an earth connection because its not metal in construction. There is a diagram showing this in the instructions but it is rather small.
