The 5050 LED is replacing the 3535 LED, which has long been the leader in the outdoor lighting market. The existing ceramic-based 3535 has excellent reliability but is expensive. At present, the 5050 LED, which has achieved remarkable performance improvements in recent years, is targeting the market with price advantages. However, the 5050 LED must continue to enhance its reliability to become the mainstream of the market. The outdoor lighting industry has been looking for a more reliable and affordable lighting solution that can protect our safety and properties.

Samsung’s High Power LH502D is the answer to all these problems and is the ideal outdoor light source for overcoming the limitations of current outdoor lighting products.

Scientifically Proven High Reliability

To prove the powerful performance of LH502D, Samsung conducted reliability tests under various circumstances. Rigorous tests were set up to prove LH502D’s high durability compared to the existing outdoor lighting solutions in extreme conditions such as high temperature, harmful gases, and salty humidity, which are often experienced outdoors. The result confirmed that the Samsung LH502D has superior reliability in comparison with other similar solutions in the market.
