SUNMASTER SONT+ DS 600w

Description

SUNMASTER SONT+ DS 600W is the double-sided high-pressure sodium grow lamp from Sunmaster that emits light from both sides of the arc tube, increasing the total light output available for reflection toward the canopy and reducing the dark zones that single-ended lamps create within the reflector cavity. We have been recommending Sunmaster DS lamps to UK growers since 2017 as an effective lamp upgrade for growers who want more from their existing 600W ballast and reflector investment.

How Double-Sided Arc Tube Technology Improves Grow Light Efficiency

Standard high-pressure sodium lamps emit most of their light from the central arc tube section, with relatively little emission from the lamp cap end where the electrical connections are made. The cap end of the arc tube faces upward into the reflector in typical overhead mounting configurations, contributing less to canopy-directed light output than the lower section. The Sunmaster SONT+ DS addresses this with a double-sided configuration where the arc tube emits efficiently in both directions — including upward toward the reflector — increasing the total photon flux available for reflection toward the canopy from the same 600W input. The result is more usable light reaching the canopy from the same electrical input, improving the lamp’s effective efficacy compared to single-sided equivalents. The enhanced Sunmaster spectrum also provides improved red and far-red output compared to standard SONT lamps, supporting vigorous flowering and bud development.

Compatibility, Lifespan, and Integration with Your 600W System

The Sunmaster SONT+ DS 600W is compatible with standard 600W HPS electromagnetic and digital ballasts and fits standard E40 lamp holders in all major reflector brands. Use with a quality hammered aluminium or parabolic reflector that maximises reflective surface contact with the enhanced double-sided output. Replace annually in continuous-use operations to maintain lumen output and spectral quality across the crop cycle. At 600W, this lamp covers a 1.2m x 1.2m canopy effectively in a flowering configuration. For growers looking to extract more from their existing 600W lighting investment without changing the ballast or reflector, the Sunmaster SONT+ DS offers a worthwhile performance upgrade.
