J.W. Speaker's XD Series LED Worklights feature a polycarbonate housing that comes thermally-conductiv, which prevents their light output from decreasing. In addition to being thermally-conductive, the XD housings have some other relevant benefits. Starting with the form factor, they come compact and lightweight to suit a wide variety of different applications. They are both impact- and corrosion-resistant, making them some of the most rugged and long-lasting products available, according to the company. They also come sealed to prevent water ingress and can stand up to high pressure washing.
