Noise not only has a great impact on one's own family, but noise can also cause problems for neighbors. With the improvement of our living standards, we must do a good job of noise insulation in the decoration, indoor sound insulation materials have appeared on the market a lot, the following small series of simple introduction to the next room insulation materials are what bar. ·Insulation material 1 soundproof felt Sound-insulating mats are the best sound insulation materials in the market. Mainly used with gypsum board, used for wall sound insulation and ceiling sound insulation, but also used in pipe, mechanical equipment, noise and damping damping. The soundproof felt is not a felt and looks completely different in appearance. The felt is light and soft, while the soundproof felt is very thin. The soundproof felt is made of odorless EPDM rubber and dozens of organic minerals in a certain proportion. The product is black, environmentally friendly and has no odor. It is a good soundproof material for low frequency and high frequency sound, which can effectively inhibit various Vibration transmission, the thickness of the material is 1mm, 2mm, 3mm range, measured by the State Building Materials Agency, weighted noise reduction Rw were 23dB, 27dB, 30dB, the flexibility of the material is also very good, you can easily bend, arbitrary ribbon cutting, Construction is very convenient and fireproof soundproof material. Soundproof felt has the following advantages: (1) Material is light and slim (2) soft, high tensile strength (3) Environmental protection, does not cause pollution to the environment (4) Suppression of the propagation of low- and medium-frequency sound waves; excellent flame retardancy (5) Convenient construction 2, polyester fiber acoustic board It is an ideal indoor sound insulation material. Its raw material 100% polyester fiber has sound-absorbing, environmental protection, flame retardant, heat insulation, heat preservation, moisture-proof, mold-proof, dust-removable, easy to cut, can be decorated, simple construction, good stability, good impact resistance, independent The advantages of good and cost-effective, rich variety of colors to choose from, can meet the needs of different styles and levels of sound-absorbing decoration. Mainly used in theaters, concert halls, museums, exhibition halls, libraries, interrogation rooms, galleries, auction halls, stadiums, lecture halls, multi-function halls, hotel lobbies, hospitals, shopping malls, schools, piano rooms, conference rooms, studios , Studios, KTV rooms, bars, industrial plants, computer rooms, homes, noise reduction, and other places with high requirements for acoustic environment and high-end decoration. 3, crest sound-absorbing sponge The noise-absorbing material of the wave-absorbing sponge is a kind of sponge formed by a special treatment of the equipment to form a concave-convex wavy shape. The interior of the sponge is filled with small voids and half-opening structures, which can absorb a large amount of incident acoustic energy and attenuate the sound waves. , to reduce the interference and reverberation of indoor sound reflections and improve the purity of the sound. The main performance characteristics are: (1) High sound absorption (2) good heat insulation (3) Flame retardant grade B1 (4) Close structure and stable shape (5) Light weight, safe and convenient construction (6) Harmless to the human body, no pollution to the environment, odorless (7) Water resistance, strong drainage after water immersion, no degradation of sound absorption performance, no change in shape (8) Can be used twice, destroyed easily, no secondary pollution to the environment Information on indoor sound insulation materials was introduced here for everyone.

Best full Specturm designed to perfectly match large areas of indooor plants, especially for Medical Plant.
COB + Dual-chip,most efficient spectrum,high PPFD.Two cooling fans with double ball(import from Japan) and big aluminum heat sink to protect the grow lights from high temperature,good cooling,long lifespan.Photosynthesis and promote healthy growth budding and flowering.
1000w/2000w /3000w COB LED Grow Light, it will give you more options when your plants need different strength of illumination.
Grow Lights are a great choice for growers who are dealing with hot HPS lights and want to change to something that's going to run cooler. Although LED Grow Lights do produce heat,the smaller models might not bring up the temperature of your grow space.Even the more powerful models of LED grow lights that produce a lot of heat still have built-in cooling systems to help prevent the heat from beaming directly down onto your plants.

WHAT MAKE UP AN EXCELLENT LED GROW LIGHT ?
1.PPFD Value : PPFD is Photosynthetic Photon Flux Density. When you choose a plant light, you should compare the PPFD values of different plant lights. The larger the value, the better the growth of the plant.
2.Actual Power: Because the actual power of the plant light always varies with different conditions, all Amazon sellers use the rated power to describe the power of the product because the rated power is constant. When you pick a LED grow light, the rated power of the plant light is a reference, and more importantly is the actual power.
3.Core Coverage: In addition to the above two, when you choose a plant light, you also need to compare the cover area of different plant lights, of course, the size of the core coverage area. In general, in germination stage, you can hang the plant light higher and the cover area is larger. In flowering stage you can hang the plant light lower and the cover area is smaller because the plant needs more light at this stage. You have to compare different coverage areas to choose the plant light that suits you.
