WATERPROOF LED DOWNLIGHTER

Waterproof downlights improve the structure of the lamp body on the basis of traditional downlights. Generally, waterproof rubber rings and waterproof plugs are added to prevent water vapor from entering the interior of the lamp body. Outdoor downlights are often rated with high IP ratings, IP54, IP65, etc. They find common use in damp environments like kitchens, outdoor balconies, bathrooms, toilets, and swimming pool areas.

etc.

SURFACE MOUNTED LED DOWNLIGHTS

LED surface-mounted downlight is mounted directly onto the ceiling, providing directional lighting. It emits light in one specific direction, resulting in a concentrated beam angle and focused illumination. This design creates strong contrasts between light and shadow, making illuminated objects stand out more prominently. They do not require recessed ceiling openings, making them suitable for retrofit projects and spaces without false ceilings.

DOUBLE TRIPLE LED DOWNLIGHTS

Grille downlights come in single-head, double-head, and triple-head, available in square and rectangular shapes. Each individual downlight head features an adjustable light module with a deep anti-glare design. This feature is valuable for accent lighting, task lighting, or general illumination, providing flexibility in lighting placement. They are commonly used alongside linear profile lights, or embedded linear spotlights in living rooms, corridors, supermarkets, hospitals, schools, and other places.

Frequently Asked Questions

Downlight generally refers to a kind of concealed lamp installed on the ceiling. All the light is projected downward. The lighting provided by the downlight is not particularly obvious, just like the light emitted from a hole in the ceiling. Its diameter is usually 2.5 inches to 10INCH. The structure of the downlight fixture is generally divided into a lamp body, a light source module, and a cover. There are many kinds of lamp body materials, such as iron surface, pure aluminum, die casting, etc.

Generally speaking, the price of the iron Led downlight is cheap, and the materials of pure aluminum and die casting are more expensive, but they are more durable. The down lamp with the aluminum shell is more used in engineering. The lighting module is usually a led light source, CFL, HID, or incandescent lamp. The recessed can light usually includes a frame, which is used to fix the device to the ceiling structure, and the accessories for fixing the lighting module, such as E27, GU10, and G24 lamp caps, are added. When these light sources are broken, they can be replaced and updated at any time.

With the improvement of people’s energy-saving requirements and awareness, people are constantly improving the down lighting to improve its work efficiency and lifespan. Due to the continuous development of LED technology, the luminous efficiency of LED downlights has generally reached 80-100lm / W, Lifespan is usually above 50000hrs (the LED downlights produced by our company in 2013 can still work with high quality up to now, and the working time has been more than 7 years), while the life of ordinary lamps is only 2000-6000hrs. At the same time, led downlights do not contain mercury, toxic gases, and liquids, which are harmless to the environment and can be recycled. These characteristics make him more and more popular with LED panel lights, especially for various commercial places, such as supermarkets, shopping malls, stores, hotels, and home places, such as living rooms, kitchens, bedrooms, bathrooms, etc

The market is full of recessed can light with different prices and quality from different manufacturers. High Quality LED downlight often depends on the following price aspects:

1. Aluminum or die-cast aluminum shell and radiator. The radiator undertakes the task of quickly exporting the heat emitted by an LED light source, so as to reduce the temperature in the downlight device and the temperature of the LED lamp bead, so as to reduce the light attenuation of the lamp bead and delay the service life of the lamp bead.

2. LED Chips. best Led downlights often use pure gold wire beads with copper support, which have high luminous efficiency, low light attenuation, consistent light color, and good uniformity, which can better create the lighting effect.

3. High Color rendering. LED light sources on the market have SMD cob, SMD lamp beads are usually above 80, and the color rendering of cob can reach more than 90. The higher the CRI, the more accurate you will be able to observe the true color of the object it illuminates, which can present the true natural color of the object being illuminated. This is extremely important for some special places, such as the lighting of museums and meat shops.

4. Anti-glare performance.Anti -Generally, different designs are made on the lamp body and optical lens to hide the luminous surface of the downlight as far as possible. When people look up 30 degrees, they can not directly see the light source. This can better protect people’s eyesight and create a more comfortable lighting atmosphere.

5. No flickering effect. Stroboscopic refers to the fluctuation of the luminous flux of an electric light source at a certain frequency. When a mobile phone is aimed at the light source, the fringe distribution can often be found, which is caused by stroboscopic light. As early as the 1990s, a large number of studies have found that there is a close relationship between the stroboscopic light source and neurological diseases such as migraine, headache, autism, visual fatigue, and discomfort, which can lead to the illusion of human eyes and then cause accidents. High-grade led downlights must use a free flicker LED power supply.

6. Choosing the correct color temperature for different application places.

According to the above points, you will get the best-led downlight.

The best wattage for led downlights should be decided by application places, such as, for residential houses, its height is about 2.7-3 meters, in this case, the best wattage is 7Watt to 9Watt. But in some commercial places such as clothing stores, it will be better to use bigger wattage like 15W 18W to increase the brightness, however, for larger commercial places like shopping malls or supermarkets, generally, it is best to install 18W 24W 30W led downlights.

From theory, the lifespan for led downlights is 50000Hrs. But from our experiences, lifespan is decided by multiple factors. Some of the bad-quality downlights maybe only last 6 months or 1 month. You have to purchase high-quality led downlights if you want downlights to last 50000hrs. The key points for led downlights are led driver and led chips. We only do high-quality led downlight fixtures with Philips/LiFud/DONE driver and Bridgelux Chips. The led downlights we produced in 2014 are still working well today. Its lifetime has been already more than 7 years.

It mainly depends on the size and height of your room, as well as the density of the installation and the power of the LED downlights selected. If there are main lighting fixtures such as chandelier lights in the room, and the led downlight is just for decoration. Then the number of downlights does not need to be too much. For example, in a living room at home, 8-10 7W downlights or indoor spotlights are generally enough. For a smaller kitchen or bathroom, then 4 7W-9W is enough.

The main reason for the continuous flashing of downlights is generally the quality problem of the LED driver, which cannot provide voltage and current stably. Some low-quality LED downlights often use non-isolated power supplies or integrate power components directly on the PCB.

Yes, it is available to do replacements or retrofits by LED sources, such as using GU10 or MR16 LED bulbs to do replacements directly. In this case, you have to check if the dimension of this gu10, and mr16 led is suitable for your existing downlight shell.
