CULTILITE – MH BULB 400W – GROW 4200°K

CULTILITE – MH 4200°K

High pressure gas-discharge bulbs known as metal halide (MH) type quartz bulbs are suitable for horticultural lighting, particularly for facilities that have little or no sunlight. The MH bulb is an arc discharge lamp that has been used for various purposes and has good color rendering with good light distribution. MH lamps contain some kinds of metallic halides and give many lines in the high pressure mercury lamp spectrum that lacks radiant energy with relatively high color temperature compared with other light sources. MH bulbs are frequently used for commercial lighting.

A 400W bulb with 4200K color temperature is not only energy efficient but it is also extremely long-lasting. These metal halide bulbs make it possible for indoor and outdoor plants to flourish and grow healthy. A 400W bulb with 4200K color temperature correctly mimics natural light as the bulbs employ full spectrum technology to deliver the best yields of high-quality plants for domestic growers. However, the performance of metal halide bulbs during the vegetative phase of the growth cycle far surpasses technology touting bulbs as full spectrum, just any blue light, or red light only. Our bulbs are designed to maximize the performance of the vegetative phase, thus ensuring that the total crops and yield remain of the highest quality.

Operating Wattage: 400W

The Cultilite bulb with MH technology has an operating wattage of 400W and a color temperature of 4200K. In addition, it has an active phase of 5% and active quartz. The size of this bulb is 47.5 x 29.5 mm, and its weight is 0.45 kg. The active phase of the device has a slight blue color when turned on, emitting a large number of color rendering indices. This device has its ballast, which contributes to the safe operation of the bulb. It is known that all additional equipment is simply made for the connection and power of such generators. The products included in this line are not afraid of fluctuating voltage in the network, are resistant to emergencies during an increase in voltage characteristics, and prevent large-scale breakdowns in the factory by the classical occurrence of errors.

Lamp Current: 3.3A

Lamp current for the Cultilite MH 400W bulb is 3.3A. The power consumption is 430W, and this value is also a major factor to think about. The bulb has a nominal voltage of 120V, and that is good for initiatives that have low voltage supply.  The manufacturer stated it generates a color temperature of 4200 K. With this level of precision, the expectation is that the bulb must be capable of producing a wide range of light suitable for these categories of plants. I have noticed that even if it is slightly more bias to the blue side, green plants seem to handle the light it produces well.

Efficacy: 103.4 lm/w

The CultiLite 4200K offers plant growth orientated color temperature and, therefore, the highest light quantity versus emitted heat output. The outer bulb reduces UV-B radiation and increased UV-A radiation. The installations are dimmable and able to work in any burning position. The system life is extended by the use of compact and robust technologies, to aid your crop to reach its full potential through outstanding growth results. The ballast supplied supports a 400W HPS and MH lamps. The bulbs incorporate the proven metal halide arc-tube design that excels versus other technologies used in horticulture, due to its ability to concentrate and isolate the spectral energy produced and to have a very quick off-strike and restrike. The bulb has specially formulated protection for use in open luminaires and can operate without the protection cover.

Importance of Color Temperature in Plant Growth

Color temperature in plant growth refers to the visible color of the light source in relation to the infrared and ultraviolet radiation it emits. A light source can be cool and blue or warm and red, depending on its color temperature. It affects the physiological functioning and bears a strong correlation with the vegetative and generative development stages of the plants. It is important to note that color temperatures should be related to specific crop stages. During the process of growth, plants have distinct levels of photosynthesis and transpiration, and different colors alter the levels of both functions. The color temperature needed depends on the physiological growth stage of the plants – the lower the color temperature, the more a red shift, which promotes stem elongation and flowering, and has a major influence on the generative development; the higher the color temperature, the more a blue shift, which drives the development to the vegetative stage.

The cool white fluorescent lamps have color temperatures in the range from 2700K to 3500K, the daylight white lamps in the range from 4100K to 4200K, and the cool white deluxe lamps in the range from 4500K to 6500K and above. The highest transmission of red and far-red light is shown by the 2200-2700K lamps, while the highest transmission of blue light is shown by the 4000K lamps.
