A New Technology, Bulb directly light up with 110V/220V, Capless&Resistance-Free, Long Lifespan.

Free of power supply LED Aluminum Board Lighting Source, a longer lifespan, directly lighting up with 110V/220V, without electrolytic capacitors and transformers.
The design of the Lighting have high luminous efficiency, Power Factor(PF)≥0.92. High-quality Aluminum Board Lighting Substrate, using 5730 chip(Gold wire, Red Copper Hold). 
High Heat Dissipation, High Brightness, Simple assembly process, reduce customer costs.

Dimmable, Constant current Aluminum Board Lighting

High Efficiency, High PF(Power Factor), without electrolytic capacitors and transformers, Single/Multi-channel linear constant current control chip.

Note

Be sure to using with matching radiator. For example, apply to bulb, downlight etc. 
Can't directly using Bare Board, or it will cause LEDs Luminance decrease faster.
