For growers who don’t want to use a Metal Halide bulb for vegetative and a High Pressure Sodium bulb for flowering, Sunmaster have developed their Dual Spectrum range of bulbs. It is a High Pressure Sodium bulb with an enhanced blue spectrum. This blue light means the bulbs can be used in the vegetative stage as well as the flowering where plants need the orange and red spectrum.
Product Description
Venture Sunmaster HPS Dual Spectrum (for growth and bloom):
– Increases chlorophyll content for a deeper green and healthier plants
– Promotes a greater leaf area / -mass
– prevents unnatural stem elongation
– produces thicker main stems
– similar to blue deficiencies of HPS
– promotes earlier flowering and number of flowers
– support accelerated linear growth
– increasing the total number of branches and internodes
– delivers an increased fruit weight
– produced higher yields (total biomass)

Venture Metal Halide (MH) lamps are designed for plants during their growing cycle, i.e. for non-fruiting or non-blooming plants: they are great for reproducing the spring to summer light spectrum. Metal Halide lighting is therefore the best HID choice for the plant’s vegetation growing phase.
The output of Metal Halide lamps is closer to natural sunlight than most other light sources.
Venture Metal Halide Lamps are a high output horticultural grow lamps specifically designed for the Vegetative/Growth phase of a plants cycle.
Each Venture MH Lamp is fitted with an E40 screw fitting for connection to most brands of HID reflectors and cables. These lamps can only be struck with a HID lighting ballast of the same wattage.
Metal Halide Lamps are for use during the Growth phase of plants (light cycle 18/6).
Venture Metal Halide Grow lamps can be used with analogue or digital ballast.
Each Metal Halide Lamp from Venture produces a light that is 4000 Kelvin – Blue Spectrum.
Venture 250w MH Lamp – Lumen Output: 22,000
Venture 400w MH Lamp – Lumen Output: 36,000
Venture 600w MH Lamp – Lumen Output: 50,000
Venture1000w MH Lamp – Lumen Output: 90,000
Remember: When handling grow lamps to ensure you don’t leave fingerprints on the glass as this will impair the performance of the lamp. It is best to use a cloth when handling grow lamps.

METAL HALIDE – (MH)
Metal halide bulbs are very efficient and produce between 65 and 115 lumens of light output per watt of electricity used. MH bulbs produce a light that is very close to full summer sun, with a spectrum rich in the blue end. This promotes fast vegetative growth and compact, stocky plants with short internodal leaf spacing.
Metal Halide bulbs create light by passing electricity through an clear inner arc tube that is enclosed in the vacuum of an outer clear glass tube. This inner arc tube contains mercury and other metals in iodide form. When electricity is applied to these metal iodides they give off very intense light and heat. The outer casing can be either clear or phosphorus coated. Most gardeners prefer the clear bulb as it produces the brightest white light available.
MH bulbs come in sizes from 70 to 1500 watts with the 250 w, 400 w , 600 w and the 1000 w being the most popular sizes for gardening. All the bulbs need to run with a ballast (basically a transformer to step up the voltage to the proper amount), that are designed to run a specific size bulb.
Medal Halide bulbs (except the 1000 w Super Bulb) should be replaced about every 9500-10000 hours or aprox.18 months (assuming an 18 hour / day on cycle).
Venture High Pressure Sodium (HPS) lamps promotes flower onset and production and is, therefore, more suited to the flowering/fruiting phase.
Proper lighting is a key ingredient in promoting robust, healthy growth as well as meeting the needs of various plant growth phases through optimized spectral outputs. Specifically tailored for the hydroponic and horticultural industries.
HIGH PRESSURE SODIUM – (HPS)
HPS bulbs are the most efficient bulbs that are commonly used by the hobby gardener. They are high in the red and yellow parts of the spectrum and low in the blue, this imitates the fall sun. Because of this spectrum some plants that are grown with HPS lights only can grow elongated and rather leggy, while many other plants are not effected by the light spectrum. For plants that normally bud and flower in the fall this is usually the light of choice because the light spectrum promotes flower production.
HPS bulbs are made out of a translucent ceramic arc tube containing a mixture of sodium, mercury and xenon gas. This arc tube is suspended in a outer glass shield (bulb). HPS bulbs range in power from 35w to 1000w, with the 250w, 400w, 600w and 1000w being the most popular for indoor horticulture.
HPS bulbs should be changed out after about 24 months. The bulbs slowly lose their brightness over time and to maintain good light quality the bulbs must be changed before the end of their rated life.
250W HPS Venture = 30 000 Lumens
400W HPS Venture = 45 000 Lumens
600W HPS Venture = 90 000 Lumens
