Philips S21 6 Dimmer Strip W/ Edison (GR) Output Connectors
Part # 71502
Mfg: Strand / Vari-Lite

Rosco LitePad Quick Kit Strand Lighting is pleased to introduce the next generation of S21 Dimmer Strips; a perfect extension of our R21, C21, and A21 range of installed dimmer cabinets. Systems can be mixed and matched as needed to create a completely flexible lighting system to meet the needs of any installation. Our dimmer strips feature quiet convection cooled IGBT dimming for low lamp noise and reliable operation. IGBT dimmers are an Insulated Gate Bipolar Transistor power device that works in tandem with a dedicated microprocessor to control almost any type of lighting load required. IGBT dimmers are completely silicon-based and operate silently without the use of chokes, and do not produce any mechanical buzz or hum associated with Silicon Controlled Rectifier (SCR) dimmers. They are smaller, lighter, and generate fewer neutral harmonics than SCR dimmers.

Ideal for smaller systems, S21 Dimmer Strips may be used in schools, churches or any facility that does not have space for conventional dimmer racks. Easy to install and use, S21 Dimmer Strips can be fed from standard breaker panels.
