CULTILITE – MH BULB 150W – GROW 4200°K

CULTILITE GROW Bulb 4200°K

CULTILITE – MH BULB 150W – GROW 4200°K was designed for the growth phase of your plants, which is vital if you want a decent yield. It generates a blue tone that offers an appropriate light spectrum to promote foliar development. The power of 150 watts is enough to promote the height of the plants and prepare them for the flowering stage when, by changing the bulb, it would cause the effect of the sun. With the Cultilite MH Bulb 150W (4200K), you will get a concentrated height that will help you achieve a uniform and dense pyramid shape. Install this specific bulb for MH technology on your growth reflector to optimize the results of your crop using a bulb of the highest quality on the market. The Cultilite MH Bulb 150W (4200K) boosts the growth phase, which is so important to achieve a successful harvest. The sowing of our plants is so delicate that without knowing the characteristics of the variety, we risk skipping some necessary steps. However, in the growth phase, we are more prone to omit various steps or requirements that all plants need to follow the same pattern or to notice any apparent damage on their leaves or roots. The most frequent mistake we make is our timing, not realizing that there are varieties of marijuana hybrids or clonally propagated plants that have particular needs in different periods within the same room.

The E-40 lighting base is standard for 40mm diameter Edison screws and is the prevalent lamp base setup in commercial and industrial lighting due to its high load capacity, wide operating voltage capabilities, and good shelf life. The E-40 base is the most frequently used light source holder in the mercury vapor, high pressure sodium, and metal halide low pressure discharge ranges. E-40 lamp holders operate with lamp stem design in accordance with international standards. This standard specifies the method for the measurement of polarization and resistance to vibration of category C and C1 E-40 caps, designed for use with tubular fluorescent lamps.

Importance of Proper Lighting in Plant Growth

Lighting is one of the most important factors to consider when developing a plant growth strategy, both in greenhouse applications and indoor growing facilities. The main source of energy for photosynthesis is light. If a plant does not receive an adequate quantity, quality, or duration of light, growth will be stunted and in the worst-case scenario, the plant could die. There are many important factors when considering lighting. Some include the type of light, the distribution of light within the plant canopy, the shadows and shading they cast, the dynamics and amount of light interception throughout the day, and the lighting costs compared to the growth potential. New technology allows the manipulation of the growing environment to increase plant growth or affect plant morphology, thus increasing production and aesthetics over traditional methods. For this reason, new discoveries, methodologies, and technologies continue to be developed and improve the capacity of photosynthesis in controlled environments, which leads to the manipulation of growth, development, yield, and quality in plants.

Colour Temperature and Luminous Flux

In lighting, the term “color temperature” is used to describe the appearance of the light given off by a lamp in terms of its warmth or coolness. Warm colors are lower on the color temperature scale and range from reds to yellows. Cool colors are higher on the scale and range from dull white to blues. Color temperatures of 2,900 K or below are considered warm, color temperatures equal to 4,100 K or above are considered cool, and color temperatures between 4,100 K and 2,900 K are considered neutral. This is the Kelvin Scale, where the lowest values indicate warm light and the highest values indicate cool light. The term “color temperature” comes from the fact that it is based on measuring the temperature at which an ideal black body radiator emits its maximum amount of radiant energy.

Luminous flux is a measure of the total visible light emitted by a light source. The unit of luminous flux is called the lumen (lm). For a lamp of constant color temperature, the amount of electrical energy used to produce light is a measure of the overall efficiency of the light source. In order to compare two light sources, both the luminous flux and the power input to the light source must be considered. The lumen is the standard unit for measuring the amount of light retrieved per second. The luminous flux is the intensity of the light observed. Different wavelengths of light have differing amounts of energy tied into their presence. The most sensitive wavelengths for the human eye lie within 450 nm to 650 nm, which means the human eye can only observe light within this range of wavelengths, so the light source considered will always be defined around these wavelengths.

PAR Watt mW and Photosynthetic Photon Flux

The amount of light that will be absorbed by chlorophyll is approximately within 280-720 nanometers. There is no chlorophyll reaction at 1-280 nanometers. This is called Photosynthetically Active Radiation or PAR. PAR covers 400-700 nanometers and also covers the peak wavelength of flowering and fruiting. 1 PAR watt covers 10.76 square meters and 1 PAR mW covers 0.01075729 square meters. For example, if a light bulb with 10 PAR watts shines, the chlorophyll is able to absorb it all if the leaf area is 10.76 square meters. So, an electric power that equals 1000 W does not mean that the intensity on a leaf that is exposed to 1000 W light will be the same. PAR mW is the measure of the amount of light in the PAR region per second and is the actual definition of light intensity. PAR mW indicates the actual effectiveness of the light and should be considered while designing your light system.
