LED Light Bulbs are described as being 'instant on', meaning that they will reach full brightness as soon as they are turned on. One of the major strengths of using LED technology to illuminate your environment is that they will be able to provide you with little to no warm up time.
The warm up time, or the time which the bulb takes to reach full brightness has traditionally been a major issue with cfl light bulbs, leading people to turn to LED alternatives.
The lack of warm up time present in LED Light Bulbs makes them ideal as an energy saving Light Bulb for a variety of lighting applications, both domestic and commercial. An LED Light Bulb will instantaneously reach full brightness when it is switched on, adding to the advantages of choosing a LED Light Bulb over other low energy alternatives such as CFLs.
