The Loadstar Pro 600W Dual Spectrum Lamp is a high-pressure sodium (HPS) grow lamp designed to provide useful light for both vegetative growth and flowering from a single 600W lamp. Its dual spectrum output combines the predominantly red/orange output associated with HPS lighting with additional blue-spectrum light, allowing growers to use one lamp throughout the crop cycle.

Designed as a cost-effective replacement lamp for compatible 600W HID lighting systems, the Loadstar Pro uses a standard E40 screw fitting and is intended to operate with a suitable 600W ballast and reflector.

Dual spectrum technology makes the lamp particularly convenient for growers who want to avoid changing between separate vegetative and flowering lamps. It can remain in the lighting system as plants move from vegetative development into flowering and fruiting.

Why choose the Loadstar Pro 600W Dual Spectrum Lamp?

  • 600W HPS grow lamp - a proven HID lighting format for high-intensity plant lighting.
  • Dual spectrum output - combines useful blue and red/orange wavelengths in a single lamp.
  • Vegetative and flowering use - designed for use throughout both major stages of the crop cycle.
  • No seasonal lamp change required - one dual spectrum lamp can be retained when moving from vegetative growth into flowering.
  • E40 screw fitting - compatible with suitable E40 HID lamp holders and reflectors.
  • 600W ballast compatibility - designed to operate with an appropriate 600W HPS ballast.
  • Strong light penetration - 600W HPS technology provides intense light suitable for established plant canopies.
  • Cost-effective replacement lamp - a practical option for maintaining existing 600W HID lighting systems.

Dual spectrum lighting for vegetative growth & flowering

Traditional HPS lamps produce a spectrum heavily weighted towards the warmer red and orange wavelengths commonly associated with flowering. Dual spectrum HPS lamps modify this output by introducing additional blue-spectrum light.

This broader output makes the Loadstar Pro suitable for vegetative growth as well as flowering, providing growers with a straightforward full-cycle lighting option without having to change between separate metal halide and HPS lamps.

The lamp remains particularly well suited to flowering applications while the additional blue component makes it more versatile for earlier stages of established plant growth.

Proven 600W HPS technology

High-pressure sodium lighting has been widely used in controlled-environment horticulture for many years. A 600W HPS system produces intense light from a relatively compact lamp and can be paired with a suitable reflector to distribute that light across the crop area.

HID lamps generate considerable heat during operation. Appropriate ventilation, reflector positioning and plant-to-lamp distance are therefore important parts of any 600W HPS installation.

E40 fitting for compatible 600W lighting systems

The Loadstar Pro 600W Dual Spectrum Lamp uses an E40 screw base, the common large-format lamp fitting used across many single-ended horticultural HID reflectors.

The lamp requires a compatible 600W HPS ballast. The ballast regulates the electrical supply required to start and operate the lamp and should always be correctly matched to the lamp wattage and type.

Before replacing an existing lamp, isolate the lighting system from the mains supply and allow the old lamp and reflector to cool completely.

Ideal as a replacement 600W grow lamp

HID lamps gradually lose light output through use even when they continue to illuminate normally. Replacing ageing lamps can therefore be an important part of maintaining the performance of an existing HID lighting installation.

The Loadstar Pro provides a straightforward replacement option for suitable 600W HPS systems, particularly where a dual spectrum lamp is preferred for both vegetative and flowering use.

Loadstar Pro 600W Dual Spectrum Lamp FAQs

Is the Loadstar Pro 600W an HPS lamp?

Yes. It is a 600W high-pressure sodium grow lamp with a dual spectrum output.

What does dual spectrum mean?

Dual spectrum HPS lamps supplement the predominantly warm red/orange output of conventional HPS lighting with additional blue-spectrum light, making the lamp more versatile across different plant growth stages.

Can I use the Loadstar 600W lamp for vegetative growth?

Yes. The dual spectrum output is designed to make the lamp suitable for vegetative growth as well as flowering.

Can I use the same lamp for flowering?

Yes. Flowering is a core application for HPS lighting, and the Loadstar Pro can remain in use as plants move from vegetative growth into the flowering stage.

What fitting does the Loadstar Pro 600W use?

It uses an E40 screw fitting, commonly found on single-ended HID horticultural reflectors and lamp holders.

Does this lamp need a ballast?

Yes. The lamp must be operated with a suitable ballast designed for a 600W HPS lamp. It must not be connected directly to the mains supply.

Can I fit it into an LED fixture?

No. This is a replaceable HID lamp intended for a compatible 600W HPS ballast and E40 reflector system. It is not an LED replacement component.

Does a 600W HPS lamp produce much heat?

Yes. HID lighting converts a significant amount of electrical energy into heat as well as light, so suitable ventilation and safe clearance around the lamp and reflector are important.

Should I touch the glass when fitting the lamp?

It is good practice to handle HID lamps carefully and avoid unnecessary contact with the glass. Always install or replace the lamp with the lighting system isolated from the mains and completely cool.

Is this a good replacement for an old 600W dual spectrum bulb?

It is suitable as a replacement where the existing lighting system uses a compatible 600W HPS ballast and E40 lamp holder. Always check the ballast and reflector specifications before installation.
