What are led bulbs?

LEDs are a light source that is often used in signs and displays. The acronym stands for “Light Emitting Diode” and refers to any semiconductor light source that emits visible light when an electric current runs through it. Although LED lighting has only recently become more popular, the technology was first developed by Russian inventor Oleg Losev in 1927.

Small, compact, and cylindrical are the words that come to mind when thinking of LEDs. LED lights are available in multiple colors, including white, red, green, blue, and yellow. They can also be combined to create virtually any color imaginable.

LED Light Buying Guide - Things to Know before buy

Before you buy an LED light bulb, there are a few factors that you will need to consider to get the most out of your purchase. Ensure that the power draw is compatible with your electrical system and fixture before purchasing an LED light bulb. If your home uses dimmer switches, it’s essential to choose a brand of LED light bulbs compatible with these systems, as some are not. 

You should have a complete idea about the IP rating of led light before buying. You can read the full guideline here.

Let’s have a detailed discussion about this:


Lumens are for LEDs, as watts are for CFLs. So the wattage of a product is not always a good measure to judge its brightness. LEDs have much higher lumens per watt than incandescent, so they can often produce more light with lower wattages. When comparing a 60-watt incandescent to a 9-watt LED bulb, for example, you’ll see that it is nine times brighter.

LED bulbs are available in a wide range of voltages. For example, you can find LEDs that run on standard household voltage, around 120 volts. This is the same as incandescent bulbs. You can also find LED bulbs compatible with solar panels and batteries. They can even run on voltages as low as 3 or 4 volts!


LED lights are available in a wide range of color temperatures, so you can get just the warmth you want. But if you aren’t sure what color temperature is best for your needs, stick with soft white bulbs. They emit a classic, warm glow and go well with most décor schemes. If you’re looking for an electric blue or green to add a bit of color or modern look, then cool white or daylight LED bulbs might be what you’re looking for. LEDs also come in many different shades of white and other colors like red and green, serving as holiday lights.

Always check the box for color based on the temperature displayed on the Kelvin scale. The higher the Kelvin number, the bluer the light, and the lower the Kevin number, the hotter the light.

  • Yellow light – 2700-3000K
  • White light – 3500-4100K
  • Blue light – 5000-6500K

LEDs are cool to the touch, so you don’t have to worry about your kids burning their hands on an LED bulb. This makes them especially good for under-cabinet lighting and lamps that can be touched or reached easily. Avoiding LED bulbs in enclosed fixtures is recommended due to heat build-up, shortening their lifespan.


LEDs are available in the screw, bayonet, and wedge sockets. Make sure your old sockets are compatible with the LED bulb you want to buy. Otherwise, you’ll need to change the socket too for it to work.

When purchasing a new LED, remember to select the right spot, depth, and socket style. Even if you’re switching from CFL to LED, it’s essential to choose the proper position, depth, and kind of socket. Old or damaged sockets should always be replaced.

There are different types of led sockets like:

  • Bayonet Cap
  • Small Bayonet Cap
  • Edison Screw
  • Small Edison Screw
  • GU10
  • MR16

Other widely used LED light bulbs have the ones found in exit signs and traffic lights. The latest LED light bulb type is flexible LED strips that can decorate your house, bicycle, or automobile.


How do LED light bulbs work?
Ans: To understand how LED light bulbs work, we must first know that all electronic devices and appliances require electricity (the flow of electrons) to function. When electricity travels through a wire, it generates light in the form of visible or infrared radiation. LEDs are made of semiconductor materials like silicon, germanium, and gallium arsenide, containing impurities to create a p-n junction. When voltage passes through this junction, electricity is generated, transformed into visible light.


Why is LED Lighting the next generation of lighting?
Ans: LED lights have several advantages over incandescent and CFL bulbs.
LEDs produce more light with less energy which means you can save up to 80% of your electricity bills compared to conventional lighting. An LED bulb uses only 20-25% of the power consumed by an equivalent CFL light for producing the same amount of light. This is an advantage because it makes them cost-efficient and environmentally friendly.
LEDs are also more durable than CFL or incandescent bulbs as they last up to 50 times longer.
Most LED lamps are shockproof, mercury-free, and highly reliable, which means you can install them in places where conventional lamps cannot be used.
An LED light also uses minimal space, making it ideal for narrow fixtures and tight spots where lights using fluorescent tubes or halogen bulbs cannot be placed.


What features should you look for in an LED light bulb?
Ans: There are several factors that you must consider before purchasing an LED light bulb, such as lumens, watts, and voltage. For example, a 60-watt incandescent light bulb produces 800 lumens, whereas a 9-watt CFL (Compact Fluorescent) emits 800 lumens. When you are buying LED light bulbs, it’s essential to check the number of lumens they produce so that they can provide you with enough lighting without being too bright or too dim.


Is LED lighting superior to incandescent or halogen light?
Ans: Absolutely! LED lights provide low-level illumination for extended periods, making them ideal for commercial applications.
Incandescent bulbs are inefficient in converting energy into light and heat. Instead of creating light, they produce 80-90 percent of their energy as heat. LED lights are more 85 % energy-efficient than incandescent bulbs. As a consequence, they require less power to produce the same amount of light.


Are LED lights cheaper to run?
Ans: Not only are LED lights more energy-efficient than other types of lighting, but they also save you money on your electricity bills. Since they emit very little heat, less power is required to cool them down, which means reduced cooling costs.
A 60-watt incandescent bulb can be replaced with a 12-watt LED.


What causes LED lights to flicker?
Ans: Dimming a light or changing its color temperature can cause LED lights to flicker. Flickering results from the human eye’s inability to see slow changes in light levels. This problem can be solved by ensuring proper insulation between AC power circuits and dimmer switches, properly shielded wiring, and low-frequency electronic ballasts.


Are LED lights suitable for growing plants?
Ans: LED lights are used by people growing plants indoors to provide essential light for photosynthesis. These lights produce little heat and consume less power than other types of lighting, making them ideal for plant growth.


Are LED lights bad for your eyes?
Ans: LED lights are low-intensity lights which means they don’t pose any severe health hazard to your eyes. Since these are not high-level light sources, you need not worry about eye strain or fatigue that people often experience after staring at incandescent or fluorescent lamps for a long time.
LEDs are now being used in cars and to light highways and streets. They save energy and money, reduce greenhouse gas emissions that cause global warming, and help save the environment.
