Unlike standard single-row strips, this model features three parallel rows of surface-mounted diode (SMD) chips to maximize lumen output.Thick Protective Casing: The clear, thick PVC or silicone extrusion encasing provides durable weatherproofing (typically rated IP65), making it suitable for both heavy indoor architectural molding and outdoor landscape perimeter lighting.Commercial Spool Configuration: Wound onto a heavy-duty black plastic reel, this layout is typical for professional 100-meter continuous runs.High-Voltage Design: The dense printed circuit board (PCB) markings and internal component layout indicate this is an AC high-voltage system (usually 110V or 220V) that operates over long continuous distances without experiencing significant voltage drop.
