Philips has announced its MASTER LED collection of LED lamps that can be used in luminaires with E27 and GU10 sockets. The 7W E27 A55 lamp, identical in form factor to a conventional light bulb, is most interesting, suitable for retrofit of 40W incandescents for nearly 83% energy savings in general lighting applications. The lamp [...]

Cooper Industries has announced the acquisition of Irvine, CA-based Illumination Management Solutions, Inc. (IMS). IMS is a developer of specialized optics and system design for LED luminaires.
