Best Energy Efficient Light Bulbs For Home – We’ve all heard the story of Benjamin Franklin and his lightning kite. And most of us know about Thomas Edison’s endless experiments with light bulbs. But these days, there are a lot of different lighting options. Most of them are driven by aesthetics, but there are other factors as well.
For the modern consumer, energy efficiency is more important than style. It’s not just about reducing utility bills. Light bulb users are also concerned about energy conservation and environmental protection in general. So, let’s see which bulbs are best for your pocket.

Best Energy Efficient Light Bulbs For Home
Ever wonder why your room feels cooler (and quieter) during a power outage? It is because energy cannot be created or destroyed. It can only be converted from one form to another. With traditional light bulbs, heat energy is converted into light energy, although much of it is wasted along the way. Unfortunately, that “wasted heat” still consumes electricity.
Best Energy Efficient Light Bulbs
So if you want to make your light bulbs more energy efficient, you can either reduce the heat output, use more heat released, or convert more heat into light. Different types of bulbs do this in different ways. Some create a vacuum inside the bulb so that the filament glows brighter and emits more visible light. Others use gases to illuminate the light produced.
In some lights, filaments and gases are omitted. Instead, semiconductors are used. These semiconductors pass an electric current through a diode with a negative charge. Electrons inside the current release photons pumped with electromagnetic radiation. When these photons collide and combine, they produce bright lights while consuming minimal energy.
When dealing with light bulbs, some ideas may seem foreign. For example, there is a trend towards using artificial LED grow lights to simulate photosynthesis. This looks at the quality and intensity of the light produced and whether it can cause germination and growth. But on a more basic level, it helps to know the difference between energy used and energy produced.
To help us understand this better, let’s look at some common powers and how they translate into brightness. We will rate the brightness (lumens per watt) of dim and bright bulbs. For reference, lumens are abbreviated as lm, watts as W, and volts as V. Roughly, incandescent tungsten bulbs produce 10 lumens per watt, while CFLs provide closer to 40 lumens per watt.

Although the premise of the bulbs is similar, their specifics vary. And it’s these variations that dictate how efficient your bulbs are. The goal is to collect the maximum amount of heat and smoothly transform it into light waves, so let’s see how each category of light bulb does this.
Of note, light bulbs were marked in watts until 2011, when the FTC (Federal Trade Commission) required light bulbs to be labeled in both lumens and watts. This allowed for greater transparency for consumers while making it easier for buyers to convert their bulbs as needed.
These are the “original bulbs”. They are made from a tungsten filament attached to the base of your bulb. A glass globe surrounds the filament. The glass is usually transparent, but can also be tinted or colored according to preference. The bulb gets extremely hot when the lights are on, so never touch an empty bulb. You risk burning yourself or even cutting yourself if the light bulb breaks in your hand.
Inside the glass, the manufacturer could charge nitrogen gas to make the filament glow brighter, releasing larger amounts of light. The most common tungsten bulb for household use is the 60W bulb. It produces 700 to 800 lumens, but wastes a lot of heat energy as it dissipates.
Light Bulb Types
This means that tungsten lights make your room significantly warmer. In other types of tungsten bulbs, the glass globe has no gas in it. Instead, all the air and other gases are sucked in, leaving a vacuum. Both heat and light move faster in vacuums, so the bulbs are more efficient.
Tungsten bulbs remain in good working order for up to 1,000 hours of use. They produce mostly warm, yellow light, which is about 2,700° Kelvin (warm white or soft white). This light temperature is often described as “soft white”. These bulbs are the most common…and the least energy efficient. Their estimated efficiency is 8 to 10 lumens per watt. The rest is wasted.
They use the same technology as standard incandescent tungsten bulbs. The central filament is heated and the surrounding gases illuminate the red glow to release more lumens. Halogen bulbs get their name from the halogen gas that fills the glass globes. In addition to halogen, these bulbs (or lamps) are sometimes infused with bromine, iodine, or other inert gases.
In halogen lamps, the “fill gas” does not directly touch the hot filament. The filament is enclosed in a transparent glass envelope, which is in turn encased in a larger glass globe. Halogen bulbs are smaller than tungsten bulbs and last longer. They don’t get as hot to the touch because there is an extra layer of gas and glass between your fingers and the heat and light source.
Does Led Bulbs Use A Lot Of Electricity
The brightness of halogen bulbs (they are more often labeled as lamps) is about 12 to 15 lumens per watt. This is a slight improvement over tungsten bulbs. So if you’re looking to replace a 60W tungsten bulb with a halogen lamp, you’re looking at a 40W to 45W halogen bulb. Halogen bulbs are sometimes mounted in reflector cups to improve light direction and intensity .
Fluorescent lights are popular in greenhouses because they provide illumination without interfering with your plants’ temperature settings. But if you want high energy efficiency for your gardening needs, you should probably go for an LED grow light. It will lower your utility bills, and that’s essential because you’re also spending on irrigation systems, fertilizers and pest control.
But while installing fluorescents in the indoor garden, also think about the configuration. Old fluorescent lights were long cathode ray tubes that needed an elongated socket and a starting fuse. Today’s fluorescents can fit perfectly into a tungsten socket without the need for additional customization. These bulbs are called compact fluorescent lamps (CFLs).
CFLs are still the typical cylindrical fluorescent tubes. But these tubes were folded, corrugated, or coiled to take up the same amount of space as a tungsten light bulb. The two ends of the tube connect to a single socket rather than two cathode poles. And like regular fluorescent tubes, CFL tubes are filled with mercury and other gases. They can last up to 10,000 hours.

The brightness levels of CFLs are 30 to 60 lumens per watt. Some fluorescents can produce up to 90 lumens per watt. And because they are fluorescent bulbs, they give off ‘cool light or ‘blue light’. This light is approximately 4,100° Kelvin (bright white or cool white). High lumen CFLs can reach up to 5,000° Kelvin to 6,500° Kelvin, which is the same as daylight at noon.
These bulbs have become popular in recent years, so we consider them “new technology”. But the first LED light bulb was invented in 1962 by Nick Holonyak Jr. and his colleagues at General Electric (GE). Instead of using heat to produce light, LEDs use photons. LED chips are much smaller than halogen filaments or tungsten filaments and are sometimes mounted in doubles or triples.
The basis of an LED chip is a negative diode. When electricity passes through the diode, the electrons release photons. These photons mix to release light. Because it takes very little energy to release these photons, and because their collisions produce so much light, LEDs end up being four to five times more energy efficient than their tungsten cousins.
For the same reason, LEDs don’t get as hot as filament bulbs. And because the diodes are so small, you can fit more bulbs in the same space. That’s why LED strips are one of the most popular forms of LED lighting. LEDs are also commonly equipped with RGB filters that allow colored light. You can get seven or more color selections within the same LED strip.
Light Bulb Types: How Much Do Led Lights Save Per Year?
Of all the light bulbs we reviewed, LEDs are the most energy efficient. But because their chips are small and there are more diodes per bulb, the conversion is not so simple. If you want to replace a tungsten or halogen lamp with an LED, they must use the same type of socket. Alternatively, get self-adhesive strips that emit the same number of lumens.
This is a convenient option as it will drastically reduce your energy bills and will not require labor costs or renovation fees. Find a convenient spot – preferably at the corner of the wall and the floor or the wall and the ceiling – and stick your LED strips. Walls are ideal because they reflect the light from the LED chips and then help it “travel” further around the room.
The other benefit of LED replacement bulbs is the backup factor. An LED strip might have forty or even fifty chips along a two-foot wire. So even if some of the bulbs explode or fail, you’ll still get plenty
