What is an LED light?
LED lights are considered a solid state lighting bulb (SSL). This means that instead of generating light and heat through something, they produce light through diodes or semiconductors. These conductors are known as a p-n junction 1, where positively and negatively charged ions meet. They force the electricity to run in a particular direction, which produces light. If the wrong type of voltage is supplied, you may hear a buzzing sound when using a dimmer meant for incandescent bulbs. Therefore, if you are switching to LED bulbs, you may need to replace your dimmer switches.
Why are LED lights not used in table lamps?
They are not always suitable for table lamps because they do not cast consistent light. For these purposes, invest in what is known as symmetrical LED lights, which are LEDs that have a diffuser to cast the light evenly around the room. These lights often have LED clusters inside that produce light in a variety of directions, making them easier to use anywhere. Always check the label to determine which type you are purchasing.

Luminous efficacy is basically how well a light bulb produces visible light in comparison to the power consumed and the amount of lumens generated. Simply, it is how many lumens are produced per watt.
Can LED lights be improved?
The answer to the above question plain and simple: NO, not only will the light levels improve, but will maintain their brightness levels for the entire duration of the LED tube’s life. Which cannot be said the same for fluorescent tubes.
Do fluorescent lights flicker?
How often have you walked in an underground garage or down a hallway, only to notice the ominous light flickering. As fluorescent tubes expire, their light levels decrease significantly…and eventually they start to flicker. In comparison, LED tubes do not flicker or decrease the amount of light coming from the bulb. The light level always remain the same – as the tube reaches the end of its life, it simply stops working. No decrease in lighting, no flickering, and most importantly no creepy experience for your tenants!
