How to choose LED Tube
1. LED tube is also commonly known as light tube and fluorescent tube, and its light source uses LED as the illuminant. The traditional fluorescent tube is also called a fluorescent lamp. There is a filament at each end of the lamp. The lamp tube is filled with a small amount of argon and dilute mercury vapor. The inner wall of the lamp tube is coated with fluorescent powder. Make the phosphor emit visible light. Led lamps have many advantages and are generally used for general lighting, office buildings, shopping malls, restaurants, schools, homes, factories and other indoor lighting.
2. Since LED lamps are gradually popularized in the market now, LED lamps and traditional fluorescent lamps have different power supply methods. In order to let the majority of compatriots and users who care about this product understand the installation of this lamp Way. Today, I specially sorted out my personal experience, and I hope it can be helpful to everyone. Now LED lamps are basically built-in power supplies, so basically they are mainly to replace the original fluorescent lamps, while traditional fluorescent lamps are divided into two types: inductive fluorescent lamps and electronic fluorescent lamps.
How to choose LED Tube
1. Luminous efficiency: The higher the luminous efficiency, the more power saving. Generally, it is recommended to choose the luminous efficiency [lumens (lm)/watts (w)] of LED lamps to be higher than 80LM/W. Such indicators are in the growth period. Select a higher value to save power.
2. Color rendering index: The color rendering index reflects the authenticity of the color of the object after being illuminated by light. The current LED light display index standard is greater than 75. It is recommended to choose 80 or more. If you have a studio at home, you can choose a display index Tall bulbs, which better reflect the authenticity of the color.
3. Color temperature selection: LED lighting with different color temperature can be selected for different environments. The color temperature range is 2800-6600K. The smaller the value, the yellow light will be biased, otherwise it will be blue and white light. Yellow light is more suitable for bedrooms, living rooms and other occasions. To create a warm and comfortable feeling. The white light is brighter and clearer, which is more suitable for study, kitchen, etc.
4. Product quality: Household led lighting is mainly composed of three major parts: shell components, driving power LED. Because the LED lamp generates a lot of heat, choose a shell with good heat dissipation. In addition, the power factor of the driving power supply needs to be above 0.9; the LED chip directly determines the brightness and decay of the lamp bead.
