PHILIPS GREENPOWER EL-1000W DE 400V

Description

The Philips Greenpower EL 1000W DE 400V is a professional, dual-ended high-intensity discharge lamp from Philips, one of the world’s leading horticultural lighting manufacturers. The Greenpower EL represents Philips’ commitment to lighting performance that is validated and trusted by commercial greenhouse operators and serious indoor growers across the world. At 1000W in the dual-ended (DE) configuration, this lamp delivers the highest photon output per unit of a HPS lamp available — producing the light intensities required to maximise yield potential in large-scale indoor growing operations.

Why Dual-Ended Technology Outperforms Single-Ended HPS

Traditional single-ended high-pressure sodium lamps connect to their ballast at one end. Dual-ended lamps connect at both ends of the arc tube. This design change has significant consequences for lamp performance. The electrical connection at both ends allows a more stable, more consistent arc discharge, producing higher luminous efficacy (more photons per watt) and a more consistent spectrum throughout the lamp’s rated lifespan. Single-ended lamps lose a meaningful proportion of their output in the first 500 hours of operation as the arc tube blackens. Dual-ended lamps maintain output more consistently over their rated lifespan. The 400V operating voltage of the Greenpower EL also contributes to efficiency. Higher voltage operation at equivalent power means lower current draw — reducing resistive losses in the ballast and cabling and producing more of the supplied electrical energy as usable light output. At The Horticulture Company we have supplied Philips Greenpower lamps to professional growers since we opened. The commercial-grade quality and performance consistency are the reasons they remain the choice of serious growers despite the growth of LED technology.

Ballast Compatibility and Practical Guidance

The Philips Greenpower EL 1000W DE 400V requires a compatible dual-ended 400V DE ballast. Do not attempt to run this lamp with a single-ended or incorrect-voltage ballast — damage to the lamp and ballast will result. Pair with a DE-specific reflector housing that accommodates the dual-end connection format. Run at full power throughout the vegetative and flowering stages for maximum photon output and yield potential.
