    Generally,You can find two sorts of develop lights utilized in horticulture.one is Large Intensity Discharge Lights (HID) - These can be found in two types, the Metal Halide Grow Light (MH) along with the High Pressure Sodium Grow Light (HPS) Metal Halide - bulbs are made for plants through their rising cycle. That's, for non-fruiting or non-blooming plants. Metal halide lighting is therefore the most beneficial HID choice to the plant's developing phase. High Strain Sodium Lights (HPS) - The HPS expand light is made use of mainly for plants which might be inside their blooming or fruiting phase. Modern substantial pressure sodium lighting can, even so, be bought, and that is enhanced for blue spectrum (for vegetative development) and for red spectrum (for flowering development). This means that they might be applied during the whole expanding course of action for many sorts of plant. Fluorescent Develop Lights emit much less light than substantial intensity discharge lights and whilst they could be applied throughout the plant cycle their lack of brightness will develop small yields....

    High pressure sodium lamp and metal halide lamp is high intensity discharge lamp,is it ok to use the same ballast drive the two lamps? High-pressure sodium lamp and metal halide lamp, although is the high strength gas discharge lamp, but because of the different substances, the luminous efficiency is also different, in the design of light source, the same power high pressure sodium lamp and metal halide lamp, the design of the current and voltage is different. Therefore, light ballast for metal halide lamp and high pressure sodium lamp should not be mixed. Some users mix metal halide lamp and high pressure sodium lamp ballast, although it can be lit, but will be shortened the life of the bulb or due to the over high temperature of the ballast and damage to electrical appliances. James lighting provides the light ballast for metal halide lamp and high pressure sodium lamp. User can choose matching appliances (as by hid do light source due to the high efficiency, high life, high irradiation angle and is widely used in outdoor lighting. However, due to the current technology is not fully mature, especially in the light of metal halide lamp light source. Due to the current domestic in this industry, a blind, often the lamps of the IP level design is very high, so invisible will increase the difficulty of design and design costs. In fact, as long as the water is not used for the water and the bottom of the outdoor lighting lamps as long as the IPX3~IPX5 can be designed, and according to the actual use of the occasion can also be installed in the lowest part of the installation of drainage holes. And this is more advantageous to the electrical heat....

    When people go to the supermarket to buy a light bulb, the incandescent lamp, energy-saving lamps, LED lamps, in the end what kind of lamp lighting effect is good? Experiment: incandescent lamp I bought three of the common lamps on the market to carry out a contrast experiment. These three lamps are incandescent, energy-saving lamps and LED lamps, the price from 3 yuan to 49.8 yuan range. The incandescent lamp power rating of 40 Watt, energy-saving lamp nominal power for 8 W, its nominal equivalent to 40 watt incandescent lamp brightness, and the rated power of the LED lamp for 5 watts, the nominal brightness is quite to the 40 watt incandescent lamp in a dark room, the the three lamp are respectively connected to the base of 220 volts, current meter to measure current, with the real power of the measurement of light through the test current and soon obtained the real power of the three lights. Incandescent lamp current of about 40, the measured power of about 0.18 watts; energy saving lamp current is about 0.035, the measured power of about 7.7 watts; LED lamp is about 0.021, the measured power of about 4.6 watts. From these data, the incandescent lamp measured power is the highest, but also the most power LED lights...

    The working principle of 55W fluorescent light ballast as below: Due to the gas discharge lamp, such as fluorescent lamps, neon lamp, metal halide lamp is a with the V-I characteristics of negative resistance of electric light source, is negative can be seen when the lamp current is increased, the working voltage of the lamp tube drop, but supply voltage will not be decreased more of this voltage applied to the lamp tube will make the lamp current rise further, so the cycle, eventually burned out lamp or lamp extinguished, so to make the lamp works normally, in the town of flow unit, to limit and stabilize the lamp current. This limiting device is called a ballast. At present, there are two kinds of ballast for gas discharge lamps. electronic ballast principle,the ballast circuit operating characteristic curve in the circuit, working voltage of the lamp and ballast components of voltage equal to the supply voltage, could eventually make the gas discharge lamp stable work...

    Start repairing 2 damaged fluorescent light ballast. When the first electronic ballast is opened, it is found that the R3, R5, have been ablation, the meter measuring Q1, Q2 has been damaged, and then measuring the capacitance of the C5 has been broken down. In the daily collection of components to identify parameters similar to the resistance, capacitance and the new 13003 to buy together, the results plug on power, did not think of things happened. Is plugged in, the fluorescent lamp start duration of about ten seconds, the second is when the fluorescent lamp lighting and flashing, followed by "squeak." a sound circuit board emerging smoke, R3 and R5 also ignite a small fire, quickly cut off the power supply, in the heart of the Dungan failed! Due to the burning of the components is more, also not determine where the fault caused by the problem is, decided to re replacement of the damaged elements, but this is to be selected in line with the parameters for the components....
