3.7V 5W COB LED Panel – 16 SMD LED, 56×12mm Panel

The 3.7V 3W COB LED Panel – 16 SMD LED, 56×12mm Panel is a slim, high-brightness LED module designed for low-voltage, battery-powered lighting applications. It integrates 16 SMD LED chips connected in parallel under a continuous COB phosphor layer, delivering smooth and evenly distributed light output across the panel.

This LED panel is also known as: 3.7V COB LED Panel, 3W COB LED Strip Panel, 16 SMD COB LED, Flat COB LED Module, High Brightness COB LED.

Although commonly referred to as a 3.7V COB LED, the actual LED forward voltage operates around 3.0–3.2V, making it well suited for use with single-cell 3.7V lithium-ion or LiPo batteries when proper current control is applied. Due to its high current draw, this COB LED panel produces strong illumination and is widely used in DIY lighting projects, rechargeable emergency lights, portable lamps, torch lights, battery-powered panels, and custom LED designs.

If you are searching for a 3W COB LED panel price in Bangladesh, this model is a popular choice for its slim form factor, wide light spread, and compatibility with lithium battery systems.
