LED wall washers and LED hard light strips are linear lamps, which are called line lights in the lighting industry. However, LED wall washers are generally used for outdoor landscape lighting, LED hard light strips are generally used indoors more! Both have their own strengths, and there are many differences between the two. For example, it includes uses and properties as well as materials, as well as appearance structures. One: Use The LED wall washers illuminate more light than the hard light strips and have a wider area. LED hard light strips are more suitable for use in jewelry counter lights. If they are used on the outer wall, it is not very suitable. If it is to be used on the outer wall, it should be used for those with an illumination height of less than 1 meter. It is better to use a wall lamp if you want to take a high range. Two: Appearance structure LED wall washers are made of high-power LEDs, and it is best to require a waterproof rating above IP65. The LED light bar...

YJLED-004E-SN21RGB and YJLED-006E-ST14RGB is the advancement of YJLED-004D-S16RGB and YJLED-006D-S9RGB. 004E and 004D size is the same, all of them are automatic RGB led lights. The big difference is that the 004E light cap is full transparent, so it called 360 degree lights. Besides, YJLED-004E has 5 leds more than YJLED-004D, it is 15leds on the top, 6 leds on back. 004E more bright than 004D, because 004E has more leds, and its back also has leds. When it light, it like a dazzling diamond. This is the video from my Spain customer, he ordered about 10,000 pcs YJLED-004E and YJLED-006E from me, all these automatic RGB led lights use for his own rides. He chose ship the goods by sea, so he can save money. At the beginning, i am so worried about customs clearance, because he never use the shipping way by sea before. But, i seem to be worried to much. My customer is a clever man, he solved all things and get the goods smoothly. Next step, my customer installed his lights on t...

The RGB LED floodlights product components. Lens + LED integrated light source (COB) + LED power supply + die-cast aluminum housing = RGB LED floodlights 1, Lens. Process: There are two kinds, one is physical tempering and the other is chemical tempering. Physical tempering is the production of ordinary flat glass or float glass by quenching or air-cooling fire treatment under specified conditions and environments. Chemical tempering is a process in which ordinary flat glass or float glass is subjected to ion exchange to change the composition of the surface of the glass to form a laminated stress layer on the surface of the glass. Good and bad discrimination: check for quality defects such as flatness, no air bubbles, inclusions, scratches, lines and fog spots. Glass with such defects will be deformed during use, reducing the transparency and mechanical strength of the glass. The thermal stability of the glass. 2, flood cover Discrimination method: no deformation, no spin lines, n...

Color temperature is a physical quantity used in illumination optics to define the color of a light source. That is, when a black body is heated to a temperature, and the color of the light emitted is the same as the color of the light emitted by a certain light source, the temperature at which the black body is heated is referred to as the color temperature of the light source, referred to as the color temperature. The unit is expressed in "K" (Kelvin temperature unit). The color temperature of the source is determined by comparing its color to the theoretical thermal blackbody radiator. The Kelvin temperature of a hot black body radiator matching the color of the light source is the color temperature of that source, which is directly related to the Planck blackbody radiation law. The color temperature is defined by the absolute black body. When the radiation of the absolute black body and the radiation of the light source are exactly the same in the visible region, the temperature...
