1. Overview

1. Product Features

● Significant energy-saving effect: Saves 90% energy compared to ordinary incandescent lamps at the same brightness, and saves 65% compared to energy-saving lamps.

● Long lifespan: The average lifespan of LED light sources can reach 50,000 hours, avoiding frequent bulb or tube replacements, achieving maintenance-free operation.

● Environmentally friendly: No pollution, no ultraviolet radiation, it is a new generation of green and environmentally friendly lighting fixtures.

● Wide working voltage range: The voltage varies within the range of 65 to 264V, the lamp operates normally, and the brightness does not change.

Effectively solves the problem of large voltage fluctuations underground that can easily burn out lamps.

● The product has pioneered the research of a new generation of heat conduction structure, achieving good heat conduction effects.
