Feature:

(1)This 4w bulb light is using high quality thermal dissipation design to maximize heat dissipation area; its unique look is based on the modern streamline, which is in line with the popular aesthetic and also create a perfect and classic shape. So it can replace conventional incandescent lamps and energy-saving lamps.

(2) Adopting high quality and low light failure, low power, high efficiency, high antistatic 3014 lamp beads as light source, the bulb light is energy saving and environmental protection, long life, up to 50,000 hours or more, impact resistance and anti-vibration. It is a new generation green high-tech products with large angle, colorful light effects.

(3) The bulb light has unique assembly and high-strength acrylic cover design. The bulb light case adopts PC flame retardant and ABS Matte , fine extruding. The reasonable optical design and the use of light shade material whose transmittance has been up to 90%  effectively improve the illuminance and brightness.

(4) Thermal RMS ≤ 5.99 °C / w (2h/Trth),good heat dissipation. The temperature of the bulb light case is below 65°(Working temperature under ambient temperature 25°-30°), it is secure to use . 

(5)The drive power adopts high efficiency constant current driver circuit, the conversion efficiency is ≥ 90%, it can be suitable for the traditional mains voltage with stable and reliable performance .

(6) The bulb light does not have infrared light and ultraviolet light, no glare, no radiation, no harm to the human body. The light is soft and pure with colorful light effects. Using electromagnetic compatibility design, it is a good way for decoration because of its environmental protection, which will help recovery and utilization.

(7) Color index is high with good color. The presentation of colors is more real and more vivid, and the identification of colors is also very good. Its viewing angle is 150 °, which is more in line with the application requirements of traditional lighting.  

(8)The size and the installation method is consistent with the traditional lamp, so it can be installed directly on the lighthouse which is for the traditional lamp. It can also match the E27 lights.
