LED corn bulb is composed of small LED lights, which can produce strong brightness. They allow you to see more clearly. When using LED corn bulbs, you do not need to replace the entire lighting fixture. All you need is to replace the light source inside the lamp. There are currently four models: E26, E27, E39, and E40. You can use them for many different indoor and outdoor applications. For example, you can use them as street lights, gardens, warehouses, workshops, parking lots, overheads, security lighting, and so on. It is a good decision to switch from incandescent lamps, energy-saving lamps, HID, HPS lamps to LED corn lamps. The LED corn bulb gets its name because of its appearance. They are light-emitting diode (LED) components on LED lights. They all have square LED lines on their surfaces. The diodes (sometimes hundreds) are mounted on a metal “cob” that has as much surface area as possible to keep the diodes cool. They usually have a beam angle of 360 degrees, so their lighting can illuminate any place.
