LED lighting is the most popular source of lighting nowadays due to their cost effectiveness and longer life than the conventional bulbs. LED lights have a semiconductor diode, which release its light from electronic current. They can be used for many purposes such as flashlights, electronic devices, vehicles and for home use. Led light colours can vary due to the composition of semi conducting materials used, so a reputable branded LED bulb can provide a brighter and clearer light.

Choosing your LED Lighting
It is very important to choose the best LED light, and following are some of the measures, which can be used while buying LED lights.
Colour Selection: Two of the most popular choices are daylight white (6000K) or warm white (3000K). Warm white has less blue light and is a close match to traditional incandescent bulbs. Daylight white bulbs deliver more of the full spectrum, which means they have more blue light and will also usually appear to be brighter. Many people describe daylight white as being colder, especially in a domestic or relaxing environment, which colour temperature is right for you is a matter of personal preference although most people prefer warm white bulbs in their bedrooms and lounge rooms, while daylight white bulbs are ideal for work spaces like the kitchen and office.
Additional Features: Some Led lamps are dimmable (but most are not), which apart from ambience can also be used for reducing energy consumption when less light is needed. So, make sure to ask about the dimming feature while buying any LED lighting.
Watts: Contrary to common belief the wattage of a bulb does not indicate the light output but rather the amount of energy that is drawn to make the bulb work, for incandescent there is a correlation between watts and brightness but not for LEDs, the whole idea of Led lighting is to produce the most amount of light for minimum energy use. So if not watts how do you know how bright a LED will be? Lumens are the answer, the lumen (lm) is the real measurement of brightness provided by a light bulb, and is the number you should look for when shopping for LEDs. For reference here are some figures-
|Energy efficiency and energy costs||Light emitting diodes (LEDs)||Incandescent||Compact Fluorescent (CFLs)|
|Life span hrs (3hrs a night)||30,000hrs Approx. 27yr||1,200hrs Approx. 1yr||8,000hrs Approx. 7yr|
|KWh used per year (20 bulbs) 3hrs per night||175.2 KWh/yr||1314 KWh/yr||328.5 KWh/yr|
|Annual cost (30c per KWh) 20 bulbs||$52.56||$394.20||$98.55|
|Contains mercury||No||No||Yes 1-5mg|
|On off cycling(switching on off quickly. Ie.in a pantry)||No effect||some||Yes can reduce lifespan drastically(no chance to warm up)|
|On instantly||Yes||Yes||No takes time to warm up|
|Durability LUMENS||Handles jarring and bumping||Glass and filament break easily||Glass breaks easily|
As you can see the power drawn for the amount of light output is considerably less in the LED bulbs.
When looking for quality LED Light, I hope the above-mentioned measures will be helpful for you choosing your LED lighting.
