- High-Quality Lamp Beads: Utilizes 5730+5050 type lamp beads for stable, flicker-free illumination. An 85% color rendering index closely mimics natural light, benefiting both fish and human eyes. Lamp beads are sealed with glue-filled technology and protected by an acrylic baffle for superior waterproofing and extended lifespan.
