One thing you need to know - we have produce so many led strips - before you produce led strips, you need to bake them for 24 hours at 60-70°C, as their MLS lever is 6. Then if you did not proceed with dehumidification, they die easily. Moreover, it is better to make them waterproof using silicone tubes. Finally, I advise you to use ws2813 and sk6822 led strips.
