Lamp holders often used for LED corn bulbs
HPS, incandescent, CFL lamps and HID are replaced or retrofit with LED corn bulbs. Because of corn cob LED lights stability and reliability, they are gradually being accepted by the market as a substitute. Economical corn LED lamp is the best lighting solution to replace and retrofit. Because LED corn lights can be made into many types of lamp holders, such as E39/E40, E26/E27, E14, G24d/G24q, G9, G4, GU10, etc. So garden lights, street lights, wall lights, high bay lights, downlights and flood lights, etc., which have small base, medium base, and large base can all use LED corn lamps. Light bulb mogul base has E39 (US Standard)/E40 (Europe Standard). LED bulb medium base refers to E26 (US Standard)/E27 (Europe Standard). Corn bulb light small base refers to E14, G9, G4. Facts have proved that using KYDLED corn cob light bulb as a lighting solution is a wise move. Long life and high light efficiency will save your money.
Retrofit metal halide with LED corn bulbs
It is relatively easy to realize the transformation and replacement of general lamps. We only need to replace the LED corn bulb with the same brightness to solve it perfectly. However, we need to pay attention when retrofit some lamp fixturers, such as high-power sodium lamps and street lamps. During our replacement, if we use corn cob LED lamps that is not compatible with electronic ballasts, this corn cob bulb will burn out easily and quickly. So what issues should we pay attention to when we retrofit with LED corn bulb?
- Use LED corn bulb compatible with electronic ballasts, which has the advantage of being able to be replaced quickly, but the cost of LED corn lamps compatible with electronic ballasts will be higher than that of ordinary voltage input LED corn lights.
- Use ordinary input voltage LED corn bulbs. Such LED corn lights have low cost, but the electronic ballast must be disconnected or bypassed. The construction will be a little troublesome and requires a professional electrician to implement it.
The LED corn lamp has a fatal flaw. If you rely on an active heat dissipation system, in many cases, considering the volume of heat dissipation, its power is not large. Under normal circumstances, active heat dissipation within 80W LED corn bulb is already the limit. If we want to increase the LED corn bulb power, we need to increase the fan, passive cooling system. Therefore, under the limitation of volume, high bay lights and closed street lights with large power must carry a fan for heat dissipation to ensure the service life of the LED corn cob light bulbs. LED corn lamp & LED corn light produce by KYD LED corn bulb manufacturer offer solutions for 70 watt to 1000 watt metal halide LED replacement.

LED Corn Lights Comprehensive Guide
What is LED Corn Light?
LED corn bulb is one different types of LED lighting. The LED chip is with 120° light beam angle. If we want to design 360° light beam angle, we have to consider emitting light in every direction, so designing into LED corn cobs is the best choice.
LED Corn Light
What Lamps can be Replaced by LED Corn Bulbs?
Compared with traditional lamps, 360° (omnidirectional) beam angle traditional lights have compact fluorescent lamps, incandescent lamps, metal halide lamps, high-pressure sodium lamps, candle lamps, etc.
Lamp bases of these traditional lamps are E14, E26, E27, B22, E39, E40 and G24. Among them, E14 is a small lamp base (mainly used in candle lights).
E26, E27, B22 are medium base (mainly used in incandescent lights and compact fluorescent lamps). E39 and E40 are mogul base (mainly used in metal halide lights and high-pressure sodium lights).
G24 is a plug-in form (mainly used in fluorescent lights).
LED Corn Bulbs Applications
LED corn light bulb lamps have all features about compact fluorescent lamps, incandescent lamps, metal halide lamps, high-pressure sodium lamps, candle lamps, etc.
So LED corn bulbs lamps are retrofit LED sunlight bulbs designed to replace the above traditional old bulbs.
What Materials are the LED Corn Lights Made of?
LED corn bulbs generally include LED drivers, LED chips and LED radiators.
1. About LED chips of LED Corn Light
LED corn bulbs manufacturer will use 3014, 3528, 2835, 5630 or 5730 SMD LED chips.
Our LED corn light factory use high brightness LED chips, so our LED corn lamps standard lumen output is 130lm/W.
If you need a high-end version LED corn bulbs, its lumen output can be up to 170lm/W.
Color rendering index over 80ra makes the light closer to sunlight light. It is best sun lamp bulb for eyes.
LED Corn Light’s Chips
2. About LED drivers of LED Corn Light
For LED corn bulbs with a power less than 60W, the LED driver only needs to be filled with thermal paste.
While the high-power LED corn lights’ LED driver is more complicated. We have to consider LED drivers heat dissipation.
When the power supply is overheated, we will reduce the output power of the LED drivers by 20% to achieve the purpose of reducing heat, and will not turn off the LED corn lamp.
When the temperature returns to normal, the LED driver output becomes normal. It can well protect the power supply from overheating and damage.
LED Corn Lamp Driver
Driver of E39/E40 LED lamp over 80W, many with an output voltage of 12V to drive the fan to reduce the temperature of LED corn bulb radiator.
Surge protection devices are applied to each LED corn light driver. It can protect the LED driver from the external surge voltage surge, and make the LED bulb have a longer service life.
3. About LED heat sinks of LED Corn Light
The LED corn light radiators can be made of different materials, such as plastic, glass, die-cast aluminum, extruded aluminum, and scaled fins.
The power of a all-plastic-radiator LED corn COB bulb can be 3 to 15 watt. The glass LED corn light bulbs power is 3 to 32W. If the aluminum sheet is added in the glass heat sink, the maximum wattage of the LED bulb can reach 50W. The power of die-casting-aluminum LED corn bulbs is 30W, 40W, 50W, 60W, 80W, 100W.
The extruded aluminum one can be produced 80W, 100W, 120W and 150W LED corn bulb. And the scale radiator can be 80W, 100W, 120W, 150W LED corn lamp. If adding a fan, the LED bulbs wattage can up to 250 watt.
In some applications, E40 and E39 LED bulbs have to add fans. For an example, as street light bulb use in street light to replace HPS with LED corn COB lights.
To replace the small sodium light fixtures in the small space, the corn lamp size must be small. But the heat dissipation of the radiator alone cannot meet the demand of the high-power corn lamp.
LED Corn Light Heat Sink & Cooling Fan
There are only two ways to change the heat dissipation conditions:
1. Increase the volume of the radiator
2. Add a system that accelerates air convection.
Due to the small space, it is impossible to increase the volume of the radiator. So we have to increase the fan to accelerate the air convection heat dissipation.
We must ensure that the LED chips have sufficient heat dissipation system, otherwise the temperature will be too high and it will easily burn the LED chips and affect the life of the LED bulb.
What is the Working Voltage of LED Corn Light?
The normal working voltage of LED corn bulb is AC100-277V or AC85-265V, which meets the requirements of North America and Japan is AC100-120V and other countries is AC220-240V.
A few 480V LED corn cobs are used in special industrial bulb or street lamp bulb. Solar street light system or home solar lighting system use 12V or 24V corn lamp.
Where are the LED Corn Lights Used?
LED corn bulbs are widely used, such as high bay fixture in warehouses, low bay fixtures in various production workshops, outdoor parking lots lights, highway street lights, commercial street lights, downlight installations in various shopping malls and offices, courtyards and parks.
As long as the lamp base matches the LED corn lamp holder, the LED corn light bulbs can be used if it is the right size for you.
What You Need to Pay Attention to When Buying LED Corn Lamps?
1. You need to figure out what lamp base you need, E14 lamp holder, E26 (used in North America)/E27 medium base, E39 (used in North America)/E40 mogul base or G24 lamp base.
LED Corn Light Lamp Base Types
2. You need to choose the suitable color temperature. The color temperature options on the market are generally 2700K, 3000K, 4000K and 5000K.
You can choose a warmer color temperature 2700K or 3000K in the bedroom, and 5000K color temperature using in the office or shopping mall, which can make people pay more attention.
3. The choice of LED corn lights power is also important. The brightness should be as the same as the original lamp.
Now the LED bulb lumen output is above 80lm/W. Our factory standard output is 130lm/W, and the highest one can reach 170lm/W.
Incandescent lamp lumen output is about 10lm/W. Metal halide lamp lumen output is about 70lm/W. High-pressure sodium lamp lumen output is about 75lm/W. Fluorescent lamp lumen output is about 40lm/W.
High intensity discharge lamp lumen output is about 70lm/W W. You can compare the luminous flux standards of the above lamps, and then choose the LED corn bulb power you need.
