DGT lighting is a professional and experienced China led downlight manufacturer. We have about 30 years history for producing LED downlight, include, led recessed downlight, led ceiling downlight, LED surface mounted downlight, dimmable downlight, integrated led downlight, waterproof downlight and eyeball downlight,etc.
LED downlight, as known as LED recessed downlight, LED ceiling downlight, is a light fixture that is installed into a hollow opening in a ceiling. When installed it appears to have light shining from a hole in the ceiling, concentrating the light in a downward direction with as a broad floodlight or narrow spotlight. Because of LED downlight is a great lighting product can create perfect lights indoor, LED downlight becomes one of the most popular LED lighting products. It is widely applied in many places, include hotels, shopping malls, offices, restaurants, commercial places and residential places,etc.
Also, DGT has many series of downlight. LED COB downlight and LED SMD downlight. The power range is from 5W up to 50W. The sizes are 2.5 inch LED downlight, 3 inch LED downlight, 4 inch LED downlight, 5 inch LED downlight, 6 inch LED downlight and 7 inch LED downlight. The shapes include round downlight, sqaure downlight and trimless downlight, etc.

COB full name is Chip On Board, refers to the mounting of a bare LED chip in direct contact with a substrate (such as silicon carbide or sapphire) to produce LED arrays. SMD full name is surface mounted diode，The SMD type LEDs are mounted on an aluminum substrate and enveloped in an epoxy resin.
First, the price of SMD downlight is more competitive than COB downlight when they have same wattage. One of main reasons is becasue SMD chip are cheaper than COB chip.
Second, SMD downlight has higher lighting efficiency than COB downlight becasue the SMD chip has high efficiency than COB chip.
Third, SMD downlight has wide beam angle usually. The reason of this is becasue SMD downlight is with many SMD chips, it’s not easy to concentrate the light. So, SMD downlight is good to use at low height indoor area.
SMD downlight is used worldwide not only becasue of the price is competitive, but also they have high lighting efficiency. They are widely applied in residential places and low height area.
First, COB downlight has more optical options becasue COB chips have higher “lumen density” than SMD chip, which means COB downlight only need one COB chip. It’s flexible to make COB downlight to have different beam angles by different reflectors. So, COB downlights are able to deliver light to ground when they are install at a high height ceiling.
Second, Currently, LED COB chips have higher quality of light than LED SMD chip, such as higher CRI, lower color tolerance. LED COB chip can reach CRI as high as 97 on market, also COB downlight are required the color tolerance below 3 SDCM （Standard Deviation Colour Matching）.
Nowdays, COB downlight not only are applied in residential places but also many commercial places, such as restaurants, hotels and shopping malls, etc. They have many optical options and higher quality of light, also they might be a little more expensive than SMD downlight.
