Thicker and Wider PCB boards
Another component that makes this LED tape commercial-grade quality is the thickness of the PCB. A thicker PCB helps disperse the heat correctly, meaning the LED will run at a cooler temperature. This helps prolong the LED’s life to the expected 70% @ 50,000 hours.
Domestic grade LED tapes cut corners by using 1 ounce PCB boards instead of 2 or 3 ounce. Cheaper LED tape also uses narrower PC boards to cut down on manufacturing costs. For example, 10mm wide PCBs instead of 12mm. Again this can effect the running temperature, which will in turn effect the longevity of the LEDs’ working life. Ultimately thicker and wider PCBs mean your LED tape will achieve its quoted life expectancy of 70% @ 50,000 hour life by helping to disperse the heat .
When correctly managed, your LED tape’s resistor sallow the LEDs to run at the right output (brightness) and temperature – whilst still lasting the 70% @ 50,000 hour expected life. All resistors on commercial grade LED tape are correctly managed for optimum performance.
In domestic grade and other lower-quality alternative LED tapes, the manufacturer cuts corners by using cheaper and less bright LEDs and then over powering the tape’s resistors to make the LEDs appear as bright as branded Epistar SMDs. This means the LED’s may initially appear to be the same brightness. But after as little as 2,000 hours, the LEDs can start to deteriorate in brightness due to the poor resistor management. Over time, this deterioration will only continue to get worse over time.
