E27 20w LED Corn Light
Long life: light-emitting semiconductor chip no filament, no glass bulbs, not afraid of vibration, less breakable, life of up to 50,000 hours (incandescent life of only 1000 hours, regular saving is only 8000 hours lamp life)
Health: Healthy light does not contain ultraviolet and infrared light, does not produce radiation (ordinary light contains ultraviolet and infrared ray)
Green: no harmful elements such as mercury and xenon, which will help recovery, but does not produce electromagnetic interference (ordinary lamp contains mercury and lead, elements, energy-saving lamps in the electronic ballast will produce electromagnetic interference)
High Light efficiency: fever small, 90% of the electrical energy into visible light (incandescent electric energy conversion 80% for the heat,only 20% of the energy into light energy)
High safety factor:the required voltage,current smaller,less heat, not produce security risk, in the mines and other dangerous places. We have provided many specification LED Corn Bulb choices, They are include, E27/E40 corn light , E14/E27/E26/G24 Candle Corn Light , Horizontal Plug Corn Light, etc.
Easy to install:LED light source shape is similar to pass incandescent, energy-saving lamps, there are E27, E40 lamp holder, on a screw can be installed without the need for change Lighting equipment.
Q: What about the lead time?
A: 3-5 days for sample order, 7-12 days for offical order.
Q: Do LEDs have a wire filament?
A: No, LEDs operate using entirely different components. LEDs are diodes - they only allow power to move in one direction. The anode (+) is where the current comes in and the cathode (-) is where the current goes out, much like the positive and negative terminals of a battery. Incandescent bulbs project light in every direction (omni directional) as opposed to LED lights which project light in specified directions (such as 20, 50 and 120 degrees) due to their package design and layout.
Q: What is a heat sink? And why do LED bulbs feel warm?
A: LEDs perform best in cool environments. Heat is the enemy of the electronic components that control the LED. It degrades both the level of light output and the lamp life. To move the heat away from the LED control module, we use what is called a heat sink. They absorb and disperse the heat created by the electronic components, keeping them cooler and increasing the lifespan of the bulb. Heat sinks are commonly made of aluminum for aluminum’s thermally conductive properties.
