1000w 4K HOR Metal Halide Lamp

Manufacturer's Code: 80091

Smaller BT-37 glass jacket (400 watt size) with 1000 watt arc tube. Horizontal operation only. Glass envelope clear. Pin must come to rest at the 9:00 position. Rated best of all standard Metal Halide Lamps.

The High Intensity Discharge metal halide grow lamps from Venture originally were and still are used for street and warehouse lighting. They have been selected for use in horticulture applications because of the light spectrum they emit. They are limited to the 3K color temperature range, which is generally considered to be a good all-around vegetation spectrum. While you could use them for bloom growth, it is suggested that you burn a High Pressure Sodium or a Sunmaster Warm lamp along with it to increase the red, yellow and orange spectrum. It is good to note that of all the colors in the spectrum, plants need a larger percentage of the blue spectrum to be healthy. This is the color that drives photosynthesis and translocates sugars. The red, orange and yellow colors of the electromagnetic light spectrum are hormonal tripping colors. This is to say that when the plants have these electromagnetic wavelengths pass through the leaves; bloom hormones are produced in the anticipation of the coming fall and winter seasons. Note: Lamps labeled HOR (horizontal) and BU (base up) are position oriented and will give you the highest light output available for their wattage. They are designed to burn in their designated positions only. Lamps labeled U (universal) may be burned in any position. However, they will be less bright than position oriented lamps with the same wattage.

The High Intensity Discharge metal halide grow lamps originally were and still are used for street and warehouse lighting.

1000w Eye Hortilux HPS Lamp

Manufacture Code: LU1000B/HTL/EN
Initial Lumens: 145,000

This lamp may be burned in any postion.

EYE Hortilux is a proven leader in the High Pressure Sodium plant growth specific lamp industry. Always top-notch quality and consumer satisfaction is very high. It is deigned to be used in 1000 watt High Pressure Sodium ballasts only. These High Pressure Sodium lamps are used in greenhouses to elevate the red, orange and yellow electromagnetic wavelengths hitting the plant. This (along with shorter photo-periods) signals the plant to start producing bloom hormones. Increased red, orange and yellow wavelengths can produce higher yields and more abundant blooms and fruiting sites when quality plant foods and bloom leaf sprays are used.

Indoor gardeners, lacking the Sun, may find that HPS lamps do not supply the necessary amount of blue light to keep plants healthy. Blue light drives photosynthesis, translocates sugars and keeps the immune system working properly. Those growing areas using HPS lamps exclusively in the bloom stages of growth may experience adverse vertical stretching and blooms located only at the top of the plant. It is suggested to burn a Metal Halide lamp along side of the HPS lamp to increase sugar production and horizontal growth. Increased insect attack in the final stages of HPS only bloom growth may also be experienced. Other options would include using Sunmaster Warm Metal Halide lamps that burn at the 3 thousand Kelvin color temperature range. They have enough red, orange and yellow light to trigger bloom hormones and an ample amount of blue to keep plants healthy and proportional in size.
