The G4 lamps are types of the bi-pin or two-pin standard, defined by the International Electrotechnical Commission (IEC).
These types of lamps have two pins at the input.
The number 4 in the name indicates the center-to-center distance between two pins, which is 4mm in this type.
The alphabet G is used to indicate that the original model of the G4 lamp had glass used in it.
Why Is It Right To Replace G4 Halogen Bulbs With G4 LED Capsules?
First, they save a lot of electricity because they operate on much lower power than halogen bulbs.
They are brighter and produce a negligible amount of heat as compared to them. Moreover, the average life of a G4 LED capsule is 30000 hours, which is ten times more than the halogen bulb. They have no toxic chemicals like mercury or Barium, thus posing no threat to human health.
Skipping the right practices during the replacement of halogen lights with G4 LED 12v lights results in problems. The common issues are Flickering, proper function, or permanent damage to the LED light. Here are some right ways that should be considered when the replacement is being done.
#1 The Right Voltage
A G4 LED capsule is a low power device with a usual operating voltage of 12 volts DC. Some companies also manufacture G4 LEDs that operate on 12 Volts AC. While the mains voltage around the world is 220-240 volts, you cannot directly connect the G4 led with the main voltage.
#2 The Right Transformer
You would need a transformer to reduce the mains voltage down to 12 volts. There are two types of transformers available in the market. One is the electromagnetic transformer and the other is electronic. Electronic transformers are preferred due to their efficiency and low cost.
#3 The compatibility
While replacing 12v halogen lights with G4 LED 12v, it is important to check the compatibility of the G4 LED lights with the lighting fixtures. As mentioned before, most of the G4 LEDs operate on DC voltage, so they will need a different power supply or transformer to operate. While all the halogen lights operate on AC, it is very important to check the compatibility of the fixture with the LED light. Both should be either AC or DC, but never different.
#4 The Right Power
It is important to check the power rating of the fixture where the halogen lights were installed. A 20-Watt halogen bulb would normally be replaced by 2-4 Watts of G4 LED.
#5 The Right size
The size of the fixture should always be measured prior to the purchase of LED lights.
#6 The Right Model
As mentioned earlier, LED lights are available in both AC and DC voltages. If you want to replace only the lights and not the fixture, you have to bring the G4 LED 12v in AC. However, it is highly recommended that both the fixtures and the lights should be replaced to maximize the long-term benefits of the replacements.
It is always recommended to do a bit of research to know which G4 LED 12v capsule is best for your home. Online forums and manufacturer’s sites are the best sources of reliable information.
G4 LED bulb comes with different light sources, SMD or COB, to check what’s the difference between them.
G4 LED lights are trending nowadays due to their cost efficiency, reliability, and many other benefits. This article highlights the right ways to follow while replacing G4 halogen lights with G4 LED lights.
