Do you know how many and what tests should LED wall washer undergo for quality certification before delivery? This article would help you to know it. Temperature Test Temperature test is a must in quality inspections of LED wall washer. There's a temperature limit for different components. During product designing, manufacturers should pay great attention to heat dissipation, especially that of certain components, such as insulation sheet. Components could be easily damaged if working under a high temperature condition for a long time. This might cause a fire or electric shock. The internal power module of wall washer is enclosed in a small space, which might lead to a heat problem. Therefore, manufacturers should select components in proper size, which would avoid the over-heating problem when the components work under full-load condition. Aging Test  LED wall washer should undergo a 24-hour aging test before delivery; and waterproof test should be carried out im...

Here I'm going to show you 7 basic specifications of LED wall washer that you'd like to know before buying. 1. Power Power is a key factor determining LED wall washer's projection distance. Generally, the power could be 18W, 24W, 36W, 48W, etc. However, the power is flexible. It could be changed upon different requests. Usually, high-power LED wall washer is always in a single row. Concerning on heat dissipation, the power of 1-meter-long wall washer, which is designed with couples of 1W lighting bulb, must not exceed 36W; otherwise, a serious Lumens depreciation would happen as a result of heat dissipation problem. 2. Voltage DC power or AC power. Usually, build-in power supply requires AC 220V(AC110 in Japan), but external power supply requires low voltage, like DC24V, DC12V, DC27V and so on. The voltage could be different due to different customers' requirements. 3. IP IP protection is also a basic specification of LED wall washer. What's IP pro...

As mentioned in " 4 Aspects to Understand LED Stage Light ", LED wall washer is a very important part of stage lighting. Well, it's not only used for stage lighting, but also a nice choice for indoor and outdoor lighting. Now I'll show you what's LED wall washer . LED wall washer is mainly used for architectural lighting purposes. As described by its name, the light comes from LED wall washer is like water washing all over a wall. It's energy-saving, and high luminous efficient. Now traditional wall washer light is gradually being replaced by LED wall washer. The power module for LED wall washer is installed inside the housing, of which the space is very limited. Therefore, some manufacturers, in order to save space, weld the pin-type components onto PCB board, which could cause a big problem in quality. These surface-mounted components could easily come off because of bad soldering. That's very dangerous. LED wall washer, controlled by a bui...
