SUNMASTER SONT+DS LAMP 1000W

Description

SUNMASTER SONT+ DS LAMP 1000W is the double-ended high-pressure sodium lamp from Sunmaster rated for the full 1000W power tier, designed for professional DE ballasts and reflectors where maximum canopy-level PPFD is the primary objective. We have been supplying Sunmaster HPS lamps to UK growers since 2017 as a quality, well-priced alternative to the Philips and Gavita DE range, offering comparable light output and spectral quality at a more accessible price point for growers equipping larger multi-light operations.

Double-Ended 1000W Performance Advantages

The double-ended lamp format maintains the arc tube under mechanical tension between its two connection points, preventing arc sag that occurs in single-ended lamps and causes output degradation and spectral shift over the lamp’s service life. At 1000W, the Sunmaster SONT+ DS delivers approximately 150,000 lumens initial output — the highest PPFD available from a standard HPS system — covering a 1.5m x 1.5m to 2.0m x 1.5m canopy footprint at recommended hanging heights. The orange-red spectral peak of the SONT+ specification is optimised for the flowering and fruiting phase, delivering the light quality that drives maximum reproductive growth in the most demanding large-scale growing environments.

Compatibility and Operating Requirements

The Sunmaster SONT+ DS 1000W requires a compatible 1000W DE digital ballast — Gavita Pro series, Lumatek Zeus, or Dimlux Expert are all proven choices for this lamp format. Use with a DE-rated reflector: Gavita Pro 1000W DE reflectors and Adjust-A-Wings Avenger DE are both compatible. Maintain a minimum 70–80cm lamp-to-canopy distance to prevent heat stress on the uppermost flowering sites. Replace annually or at 10,000 hours for consistent output — do not run degraded lamps past their service life as output reduction wastes electricity without proportional light return.

Pair the Sunmaster SONT+ DS 1000W with a Gavita Pro or Lumatek Zeus 1000W DE ballast and a dedicated DE reflector for a complete, high-output professional flowering system.
