Clear the purpose of the test, select the instrument category In short, the detection of harmful gases has two purposes, the first is to measure the explosion, and the second is to measure the poison. The so-called explosion test is to detect the flammable gas content in dangerous places, exceed the standard alarm to avoid the occurrence of explosion accidents; the test is to detect the content of all toxic gases in the dangerous field, and exceed the standard alarm to avoid staff poisoning. The range of the explosion test is 0~100% LEL, and the range of the test is 0~ tens (or hundreds) ppm, which is very different. There are three kinds of harmful gases in dangerous places. First, non-toxic (or low-toxic) flammable, second, non-combustible and toxic, third, flammable and toxic. The first two cases are easy to determine, the first test explosion, the second test, and the third case if there is a person exposed to the test, if there is no personnel exposure, the explosion can be measured. The blasting machine selects the flammable gas detection alarm device, and the toxic gas detection alarm device is selected for the measurement of the poison. 2, clear detection purposes to choose the type of instrument (portable or fixed) The long-running leakage detection of production or storage positions uses fixed detection and alarm devices; other types of portable (or pocket-sized) instruments such as inspection, emergency detection, entry detection and inspection. The instrument model contains three main contents: manufacturer, function index and detection principle. 3, clear the test object, choose the instrument model There are several principles to consider when selecting an instrument model: 1 The manufacturer is honest, reputable, and the quality of the production is guaranteed. It has passed the ISO9002 quality system certification, and has the CMC production license issued by the technical supervision department. It has the fire and explosion proof certificate. 2 The detection principle of the instrument should be adapted to the requirements of the test object and the test environment.

LED Grow Lights function by sending an electric current through a semiconductor material.This in turn excites the electrons that create a powerful light from a very small bulb.By using different materials for the semiconductor, it is possible to create LED diodes with different wavelengths of light. This makes them capable of giving your indoor plants exactly what they need for each stage of growth. How those are used will be covered further down.

Our professional full spectrum Grow Light are suitable for all the indoor plants and good for seeding, growth,flowering and fruiting stages of plants, increasing the harvest and Saving energy.
Cautions:
1.Do not use the lights in dripping water or anywhere where they will get wet, water and electricity can be a dangerous mixture
2. The working environment for the light is -20~40 degree celsius,45%RH~90%RH.
3. To protect the light, Plz cut off the power when there is a lightning strike.
4. Don`t touch or move when the light working.
Suggestions:
1.Clean the dust inside every 6 months to ensure the good heat dissipation and long life time.
2.Don`t keep too short distance to the plant canopy to avert leaves bleaching.
3. Highly hang the lamp will weaken the energy and affect the growth cycle of the plants, so the lamp should not be hang too high.
4. While taking care of the plants, please spray the leaves and branches 2-3 times everyday, to ensure the plants do not wrinkle a wither, and have no phenomenon of few fruit, and hard pericarp
