1. The spectrum emitted by the lamp shall be comfortable and eye-safe
Color rendering is greater than 80, relatively close to natural light, the color shift of the light under the item is small; according to each person's preferences, select 3000K (warm color temperature), 5000K or more (cool color temperature) or the color temperature; available smart phone camera mode, select Flicker-free luminaires (viewed luminosity-like images with flicker); luminescence spectrum wavelengths are constant. The use of inexpensive LED chips will cause color drift for a long time. Manufacturers that do not have LED spectrophotometers have a hard time producing color-accurate products.
2. Electrical Safety
The body of the LED Light is usually made of aluminum. If there is a problem with the insulation of the driving power source installed in the lamp body, it is possible to introduce the mains electricity into the aluminum lamp body. There will be electric shock when people touch it! Recently, there were reports that there were “two (such) accident reports for the world’s leading LED Lights in the European market, and dealers and distributors took measures to withdraw the market from this product”. Shanghai Shishi uses insulating ceramic bodies to make the lamp body, thereby eliminating the causes of such electric shock accidents. Lamps that pass the necessary safety certification must be selected to ensure safety.
3. Buy lights according to the lumen output not watt
Look at lumens (lm, the brighter the light source is, the larger the lumens are). The advent of LED luminaires changed the pursuing philosophy of buying lighting. If you still look at wattages to buy LED Lights, then you have to be OUT. Assuming a 30 square meter living room with a required luminous flux of 3000 lm, consumers can purchase a 200W incandescent lamp, or a 50W fluorescent lamp, or a 43W low-efficiency LED lamp, or a 27W high-efficiency LED lamp. Although the wattage is different, their final lighting effects are similar. If low-wattage LED lights are selected under the same lumen parameters, then congratulations, such a wise choice saves the household more than 37% of the electricity bill. ! In this way, taking the lumen as the parameter standard and referring to the wattage comparison will always allow you to buy high-efficiency, energy-saving and economical lamps! The LED light provided by ZGSM Tech have a light efficacy up to 165lm/W, which could help to save both the energy and the bill for you.
4. Lifetime of LED Light
The lifetime of LED luminaires is not terminated until they are not brightened, it means the time of the luminous flux reduced from 100% to not less than 70% after working. The LED lights manufactured by Hangzhou ZGSM Tech have been tested and it shows our lights have a lifetime of more than 100000 hours in the temperature environment of nearly 25°C. Because we use high quality imported chips and design excellent heat dissipation for our LED Lights.
