An electronic ballast in the 400w class with the popular Lumatek Superlumen function: Both output levels (250W, 400W) are complemented by two additional levels, each with around 10% more power! As such, HPS lamps can be pushed up to 275W or 440W. (Metal halide lamps may only be operated at their respective output level).

The popular wing reflector by Adjust-A-Wings in large. 
The large Avenger makes almost any lamp more efficient!

The popular wing reflector by Adjust-A-Wings in large! The Adjust-A-Wings Avenger Medium's glass coating increases light reflection by up to 97%. Constructed in the same way as the "Stucco" model, this reflector illuminates evenly, which enables optimal surface illumination and light output.

...

The NXE 400W from GIB Lighting is an incredibly efficient, yet compact and safe ballast, which allows the indoor gardener to care for remarkable gardens. Another practical advantage of this ballast is the choice of four output levels, which on one hand allow for the operation of a powerful 400W lamp, but also allow for dimmed, and therefore energy-saving operation (of HPS lamps only) for less light-hungry phases of the plant?s life.

...

The Adjust-A-Wings Avenger Medium's glass coating increases light reflection by up to 97%. Constructed in the same way as the "Enforcer" model, this reflector illuminates evenly, which enables optimal surface illumination and light output.

...

The popular reflector by Adjust-A-Wings, in efficient titanium white. The reflector, like all Adjust-A-Wings models, is made from light, rust-free aluminium and is coated with a resistant, easy-to-clean polymer sheeting. This sheeting is extremely resistant to heat and distributes the light more evenly than any other Adjust-A-Wing reflector. This reflector reaches slightly lower light reflection values than the Avenger models, for example, but this effect is negligible thanks to the particularly even light distribution.

...

The wing-shaped reflective surfaces mean that this reflector illuminates evenly, which enables optimal surface illumination and light output. The matte stucco surface enhances the effect of the particularly even illumination.

For more light at a much lower temperature:
Air cooled reflectors from Ventilution can achieve exactly this.

Air cooled reflectors are the solution if HPS or metal halide lighting is to be implemented in a small space. These otherwise magnificent lighting systems have the inconvenient side-effect of strongly heating the surrounding air.
However, this effect can indeed be exploited with the correct implementation to heat the grow room, although the heat generated is usually problematic, especially when multiple lamps are to be operated at the same time.

• High light output
• Suitable for the growth and flowering phases
• Optimised light spectrum

The SON-T Agro HPS 400W high-pressure sodium lamp from Philips is a lamp which can be used for both the growth and flowering phases.

...

Light is a crucial requirement for photosynthesis, and therefore also for the growth of any plant. Plants thrive best in sunlight, as this provides a balanced light spectrum. However, plants can?t always be grown outside. In most cases, conventional indoor lighting is not sufficient to ensure good photosynthesis performance.

...

Lumatek too makes use of the red light colour spectrum for its HPS flowering grow lights. With a colour temperature of 2087K, the 400W version can give off an astonishing 53,000 lumens. The PAR value (photosynthetically active radiation) indicates the spectral range of sunlight used by living organisms to perform photosynthesis. Tables and diagrams provide better explanations for this.

...

Green-Power lamps are perfect for assimilation lighting. This means that they support the CO₂ absorption (=assimilation) for improved photosynthesis, which leads to faster-growing, overall healthier plants.

...

Lumatek too makes use of the blue light colour spectrum for its metal halide growth-spectrum grow lights. With a colour temperature of 4328K, the 400W version can give off an astonishing 44,000 lumens. The PAR value (photosynthetically active radiation) indicates the spectral range of sunlight used by living organisms to perform photosynthesis. Tables and diagrams provide better explanations for this.

The efficient option from the metal halide
family: 80 lm/W with the 400W metal halide ?Growth Spectre? from GIB Lighting.

GIB also offers an affordable metal halide lamp in the 400W class. The colour spectrum of this metal halide lamp is perfectly suited for cuttings and seedlings. During the first weeks of the vegetative stage, the increased blue proportion ensures compact plant growth.

...

A cost-effective alternative. The HPS lamp by GIB Lighting.
The 400W Flower Spectre "XtremeOutput" - an efficient model.

The 400W lamp by GIB is particularly popular among beginners and hobby gardeners thanks to its value for money. The phrase "XtremeOutput" refers to the high efficiency value for a 400W lamp. This value indicates how much of the power consumed (W) by a lamp is actually converted into useful light (lm). The GIB Flower Spectre "XtremeOutput" has an astonishing efficiency value of 145lm/W, which is comparable with that of the big name brands.

...

The quality 400W metal halide lamp by Philips. This lamp emits a stable white light with a high blue content, which makes it the perfect choice for the growth phase.

...

The Venture Sunmaster DUAL 400 W is an innovative HPS light with two colour spectrums. This combination lamp was developed specifically to meet the needs of serious indoor growers who wish to give their plants the right light frequency in all stages of the growth cycle with just one lamp.

...

The brand name lamp specially designed for assimilation lighting:
The Plantastar series by Osram. 400W for efficient professional and home gardeners.

Unparalleled 400W assimilation lighting: With the Plantastar series, Osram has developed the ideal HPS solution especially for use in indoor grow areas. This HPS lamp is also in the red area of the spectrum (around 2000°K) and is therefore perfectly suited for the flowering phase. Unlike conventional HPS lamps, the Plantastar lamps have a somewhat broader light spectrum, which leads to shorter production times, healthier plants, and improved CO2 assimilation (30-40% higher blue proportion compared to the Vialox series).

Want to install an air-cooled reflector into a 160mm system? These three parts make that possible. Solid, galvanised reducer and light, flexible aluminium ducting (opaque) from Ventilution.

...

In the 400W class as well, the high pressure sodium lights from Sylvania are the ideal choice when it?s a question of affordable but reliable and long-lasting lamps. Sylvania is a subsidiary of Osram and has certainly made a name for itself in the world of grow lights.

...

They set themselves apart with exceptional reliability, a high luminous flux output (up to 141 lm/W) and first-class production quality, in the 400W class too.

...

The Sylvania Grolux SHP-TS is geared specifically towards the needs of plant cultivation, and contrary to the SHP-TS version, it has a higher blue content in the light spectrum. As light with different wavelengths is needed for different metabolic processes in the plant, the broader spectrum of the Sylvania GroLux product line helps plants to achieve a more saturated green colour and lusher growth.

...

The Elektrox Super Grow is a metal halide lamp with a blue-white light spectrum for the growth phase. At 5,600 Kelvin, it has a cool white colour temperature. With an output of 400 watts and a voltage of 120V, it helps you achieve stronger stems, large green leaves, and beautiful healthy plants. It has an E40 socket and can only be operated with a suitable ballast.

Elektrox Super Bloom is a 400-watt HPS light. The light output is 136 lumens/watt with a colour temperature of 2,000 Kelvin. Thanks to its red colour spectrum, the Elektrox Super Bloom is perfectly suited for the flowering phase, as the red content supports healthy growth and bigger yields. With an output of 400 watts, this HPS light can be used in grow tents with a floor space of up to 1 sqm.
