400w Philips High Pressure Sodium Lamp


Philips 400w HPS Lamps have a sintered aluminum oxide discharge tube enclosed in a vacuum clear soda-lime or hard-glass outer bulb. The discharge tube is filled with sodium-mercury amalgam and xenon starting gas and has a clear tubular outer bulb. These lamps improve output and profitability in all sectors of greenhouse production. They generate a spectrum with enhanced blue output, optimizing plant development and quality with good leaf and bloom color and extra branching.
