Lumatek 400 W Growth and Flowering HPS

Product detailed description

Lumatek 400 W HPS Dual Spectrum discharge lamp - growth and flowering

The Lumatek 400 W HPS Dual Spectrum discharge lamp is a high-pressure sodium (HPS) discharge lamp with a dual 2,000 K spectrum for growth and flowering. Unlike HPS lamps designed purely for flowering, its spectrum also covers the vegetative phase, allowing you to complete the entire cycle with one discharge lamp. Luminous flux 56,500 lm, PAR/PPF 700 µmol/s, E40 base.

Why dual spectrum

Dual Spectrum means that the discharge lamp emits both wavelengths supporting vegetative growth and those intended for flowering. For growers, it is a versatile choice - you do not need to change the discharge lamp between phases. The long service life of 28,000 hours and luminous flux of 56,500 lm make this discharge lamp an economical source for the entire cycle.

Installation

We recommend operating it with an original dimmable Lumatek 400 W ballast to reduce the risk of damaging the discharge lamp and ensure greater compatibility. Fit the discharge lamp into a reflector with an E40 base, such as Lumatek Xenon 2. For a larger area, consider the Lumatek 600 W HPS Dual Spectrum (400 V) discharge lamp.

Frequently asked questions

Can one discharge lamp handle both growth and flowering?
Yes. The Lumatek 400 W HPS Dual Spectrum discharge lamp has a dual 2,000 K spectrum covering vegetative growth and flowering. You do not need to change the source between phases - one discharge lamp will take your plants through the entire cycle.

What are the discharge lamp's specifications?
The luminous flux is 56,500 lm, PAR/PPF is 700 µmol/s, the colour temperature is 2,000 K and the service life is 28,000 hours. Voltage 230 V, E40 base. Operate it with a 400 W ballast, ideally Lumatek.

How does it differ from an MH discharge lamp?
HPS Dual Spectrum is a sodium discharge lamp for the entire cycle (growth and flowering) with a warmer 2,000 K base. An MH discharge lamp produces a bluer, purely growth-oriented spectrum. If you want one discharge lamp for everything, choose HPS Dual Spectrum.
