The 3528 LED's dimensions are 3.5mm x 2.8mm, making it a smaller SMD chip than those found in 5050 LED strips. The 3528 LED chip is typically used in 60 LEDs per metre of 4.8w or 5w per metre LED tape, both of which operate at 12 volts. When this SMD is used in this quantity per metre, depending on the colour, it will shine onto a surface with a lumen output of around 330-360 lumens per metre (halogen 40w equivalent). Warm and cold white (all various Kelvins required may be manufactured), red, green, blue, and amber are the hues that are accessible in the 3528 SMD. The 60 LED 3528 SMD LED tape is most frequently used as feature lighting, such as plinth lighting, cove lighting, in residences, pubs, restaurants, and hotels, among other places.
Another LED tape employing the 3528 SMD is the 9.6w p/m or 10w p/m LED tape, which has 120 of these LEDs per metre and draws 9.6w. Despite not being nearly as popular as the'standard' LED tape with 60 LEDs per metre, it is nonetheless offered in the same hues. Due to employing twice as many LEDs, the output would be exactly doubled, resulting in 660–720 lumens per metre, depending on the hue. The applications for this LED tape would still be feature lighting, but greater power than the 4.8w p/m is needed in areas with more ambient light.
These two LED tapes are both offered in an IP67 version. For LED tapes with 60 LEDs per metre and 120 LEDs per metre, the cut points would be 50mm and 25mm, respectively.
3528 SMDs don't produce much heat when used at 60 or 120 LEDs per meter—you can easily touch them with your fingertips. They need a PCB board that is at least 8mm broad and 2 ounces thick for the version with 120 LEDs per metre. You may easily install LED tape anyplace as long as it complies with these specifications because it will already have an adequate heat sink and won't need an aluminium extrusion.
The 3528 SMDs are available in several brands. With 70 percent output at 50,000 hours, the premium branded Epistar SMD offers you the brightest 3528 SMDs on the market as well as superb colour constancy and dependability. You will receive less brightness, unreliability, and colour discrepancies both inside and across reels if you pick one of the less expensive options.
