Due to the wide and varied application of g4 led bulb, g4 led bulbs can consume a large portion of the energy used to light a home or business. Around a home or office you can find g4 led bulb in many places including: recessed can lights, track lighting, home security lighting, stage lighting and use as individual spotlights in art galleries and museums. These applications often use high wattage bulbs running for many hours a day which makes them prime candidates for replacement with energy efficient g4 led bulbs. Depending on the application, a g4 led bulb will typically last five to ten times as long as a halogen. g4 led bulbs can vary widely in quality, color temperature, beam angle and a number of other factors.

Although g4 led bulb lights (mostly in the form of individual diodes) have been part of our daily life for a long time, their use for lighting purposes started only decades later. This was due to g4 led bulb low light output and to other conditions provided only by later technical inventions.

So what are the conditions that make it possible to have g4 led bulbs, which operate at mains and emit enough light to replace any of our current light bulbs?

Light emitting diodes operate at low voltage DC, therefore LED light bulbs in household use need to include internal circuits to operate from AC. Another significant condition is obviously a decent light output of the LEDs. Although, the light emitted by a single LED is increasing very fast due to the large amount of research done in the field, most LED light bulbs contain multiple diodes, to increase light emission. LED light bulbs used as a main source of lighting in households started with the introduction of SMD technology to LED lighting solutions, and was followed by high power LEDs. These are very bright LEDs, but they are difficult to place into the small space provided by the traditional light bulb.

Breakthrough products in household use were Osram’s replacement for a 40W conventional light in 2009, and Philips’ replacement of a 50W bulb in May 2010. The light bulbs created with this high light output are full replacements of previous light bulbs of filament types, with similar beam angles. At the same time, hundreds of Chinese manufacturers work on developing new LED products at a price much more available to the masses. These solutions might lack brandings that are a guarantee for quality, but might produce quality products with warranty also provided.

Another issue was heat generated by the G4 LEDs Bulbs. LEDs are heat sensitive devices; therefore their thermal management is crucial. When placed close to each other – especially with high power LEDs, which generate more heat – LEDs can easily overheat each other, which eventually leads to the failing of the device. The easiest way of avoiding the overheating of LEDs was that they were uncovered, although this meant that they were also unprotected, and this could also shorten their lifespan due to the dust or oil depositing on the LED’s surface. The best solution was the introduction of heat sinks with cooling fins into the design of the bulb itself. This provides a proper air circulation and eventually releases much of the heat generated by the LEDs.g4 led bulb

G4 LED Bulb comes in standard fittings for the sake of easy replacement, however not all G4 LEDs Bulb run at the mains, 12V LED lights are still available for running them on batteries or transformers. Transformers need to be LED compatible, as the electronic transformers most frequently used with halogen lights ruin LEDs. There is no such problem with G4 LED Bulbs which are suitable for 220V or mains in other words. So those, who wish to reduce their cost of lighting quickly, this is the solution they were looking for.
