Sometimes , Customer give us the other factory led strip light sample. Some price is very low , they want to know what is the different from good quality led strip light and what is the low quality led stirp light. In this post ,Lightstec will show you how to tell the different from each other.
LIGHTSTEC LED STRIP LIGHT
PCB：Double layer 2OZ copper PCB
Double layer copper PCB is better for heat dissipation and lower voltage drop.For project used.
Power:Our led strip light is use 151R resistance.Power 12.8W/M.Our led pass LM-80. That means our led strip light can use longer time.
Our company use original 3M tape: 9080A Check date sheet here: https://www.lightstec.com/wp-content/uploads/2018/05/3M-9080-for-led-strip-light.pdf That means our led strip light can stick strong in right use.
Our LED is 18-20lm, RA>80, light effect: 100LM per watt.The led holder is copper .Copper holder led is good at heat dissipation and not easy rusts.Life time will longer than iron holder led.
CHEAP QUALITY LED STRIP LIGHT
Single layer thin PCB
Single layer pcb voltage will bigger , for low price products.
Power:cheaper led stirp light use 181R resistance ,and power is 11.8w/m. That they just want to lower the power,because they are led strip light can not use bigger watt.Heat dissipation not good.
Cheaper led strip light use some other brand led tape. Not strong enough when use long time. But the price is low. Not good for project use.
After testing, the sample led brightness is 13-15lm,RA<80.The Led can be sucked up by magnet.That means the led holder is make by iron.Iron rusts easily.And heat dissipation not better than copper.So the life time will shorter than copper holder led.
