Know About the Materials Used In G4 LED Light Bulbs

G4 LED light bulbs are excellent replacements to standard halogen lights because of their cost-effective and energy efficient properties. These bulbs are ideal for directional spotlighting or as decorative elements for lighting fixtures at home. G4 LED bulbs can typically reduce your energy bill by up to 90%, and because of their energy efficiency, they are cooler to touch. They can last for up to five years used continuously—which is equivalent to up to 30 years of common domestic use.







What makes G4 LED bulbs energy efficient? They do not have the same filament that is used in typical halogen bulbs. A 1.5W G4 LED bulb contains a high-quality LED chip in a frosted reflector to reduce glare, while the aluminium base helps deflect extra heat. G4s are compact and can illuminate places that are difficult to illuminate, making them the choice of light fitting designers.

To achieve maximum heat resistance, some types of G4 LED light bulbs have special components, such as poly-functional hardeners, which are mixed and heated to around 150 degrees Celsius to create an exothermic reaction. Poly-functional hardeners can unlock the heat resistant and chemical resistant properties that prevent LED components and LED chip from overheating and eventual failure.

There are also G4 LED bulbs that have 12 SMD LED chips. SMD refers to 'surface mounted diode', the chips that are directly mounted onto the circuit board (eliminating the need for a reflector). They achieve excellent light output with 180-degree beam angles that can light up a wide area from a small space.

G4 LED bulbs are available in either warm white or cool white in the Kelvin Colour Temperature Spectrum, and they provide a 90-degree directional beam angle. G4 LED bulbs are non-dimmable, so they are ideal for straightforward and non-ambient lighting needs.
