Energy Efficient Light Bulbs – Which Ones Shine Brighter than the Rest?
You can make your home shine bright for less money and less impact on the environment. An average home spends about 5% of its budget on lighting, which is a lot when you think about it long term.
Energy-efficient lighting bulbs can actually cut your energy bills and this is the fastest way to save up some money. By replacing your most-used light bulbs, you can save up to $45 every year.
There are many different bulbs like CFL, LED, and halogen incandescent available with the energy star of efficacy. So, your best bet is to go with light bulbs that have that energy star.
What are Energy Efficient Light Bulbs?
Energy-efficient light bulbs represent a significant departure from the conventional incandescent counterparts that have historically illuminated households. While the traditional incandescent bulbs have served as a familiar source of light, their inherent inefficiency and limited operational lifespan have prompted a concerted exploration for more sustainable and energy-conserving alternatives. This exploratory journey has culminated in the innovation of energy-efficient light bulbs, a sophisticated array of lighting solutions that transcend the limitations of their incandescent predecessors.
The conventional incandescent light bulb, despite its ubiquity, is notorious for its inefficiency. A substantial portion of the energy it consumes is dissipated as heat rather than light, rendering it a wasteful choice for illumination. Furthermore, the fragile filament within incandescent bulbs is susceptible to damage from vibrations and shocks, leading to a relatively short operational lifespan. In response to these shortcomings, researchers and engineers embarked on a quest to devise lighting technologies that could minimize energy consumption, prolong operational life, and contribute to environmental sustainability.
What’s the Difference Between The Old and The New?
In the realm of lighting technology, a profound shift has occurred between the traditional lighting systems of the past and the cutting-edge alternatives that now dominate the market. The older, conventional light bulbs, once widely embraced for their illuminating prowess, have not only ceased production but have also been relegated to the annals of inefficiency and wastefulness.
A striking dissimilarity between the old and the new lies in their energy consumption patterns. The erstwhile traditional bulbs, despite their erstwhile popularity, exhibited a voracious appetite for energy. Regrettably, these energy-intensive bulbs were notorious for expending a considerable proportion of the consumed energy as heat rather than the intended illumination. Astonishingly, around 90% of the energy input was squandered as unwanted heat emission, a futile expenditure that resonates as a stark illustration of inefficiency. It's important to note that this excessive heat production held no practical value, as the primary objective of turning on a light is to facilitate illumination, not to generate heat.
In stark contrast, the newer generation of light bulbs emerges as beacons of progress and pragmatism. These advanced lighting solutions herald significant energy savings, thereby constituting a pivotal stride towards environmental conservation and economic frugality. By minimizing the amount of energy required for illumination, these innovative bulbs exhibit an environmental consciousness that aligns with contemporary sustainability imperatives. This, in turn, translates into tangible economic benefits, as reduced energy consumption leads to lower utility bills and a more prudent use of resources.
Furthermore, the contemporary lighting landscape encompasses a remarkable diversity in terms of color options and levels of illumination. Unlike the conventional bulbs that offered limited choices, modern bulbs present users with a vast spectrum of colors and light intensities to choose from. This nuanced customization capability empowers individuals to tailor their lighting environments to suit varying moods, tasks, and preferences. Consequently, the modern lighting experience has transcended mere functionality to encompass a dimension of personalized comfort and ambiance.
So, What Choices Do You Have?
You have various different choices for energy efficient lighting. The most popular ones are the halogen incandescents, CFLs or compact fluorescent lamps, and LEDs or light emitting diodes. They can initially be more expensive than traditional bulbs, but they can save money and make up for that during their lifetime.
They use less energy and last a lot longer than traditional bulbs. They can be found in hardware stores and stores that sell home improvement equipment. There are various controls like photocells and timers that can save you electricity when you are not using the lights.
You can use the dimmers when you want lower light levels. You should select products that are compatible with your energy efficient light bulbs. If you have some outdoor lighting that you leave on for a long time, sometimes even overnight, you can pick CFLs or LEDs which can then save you a lot of energy.
Most CFLs which are bare and spiral can be used in enclosed fixtures and it can protect them from various weather conditions. Both LEDs and CFLs are available as flood lights which means that they have been tested and are able to withstand snow, rain, and other conditions even without enclosures.
Look for energy star fixtures that have been created for outdoor use and have features like shutting off during daylight automatically and turning on when someone passes by.
Choosing the Right Energy Efficient Light Bulb for Your Needs
Navigating the plethora of options available when it comes to energy-efficient light bulbs can indeed be a task filled with choices. In order to facilitate an informed decision, it's essential to take into account several pivotal factors that can greatly influence the lighting outcome. Here are some comprehensive considerations to guide you in your quest for the ideal energy-efficient light bulb:
Brightness and Lumens
In the past, traditional bulb selection was primarily driven by wattage, but the realm of energy-efficient bulbs operates on a different metric—lumens. Lumens directly indicate the brightness level of a bulb. As a point of reference, a conventional 60-watt incandescent bulb typically emits approximately 800 lumens of light. Adjusting to this lumens-centric paradigm ensures that your chosen bulb aligns more accurately with your desired brightness requirements.
Color Temperature
The color temperature of a light source determines the character of the emitted light, whether it imparts a warm or cool ambiance. Warmer color temperatures, usually around 2700K, echo the gentle, golden radiance reminiscent of traditional incandescent bulbs. In contrast, cooler color temperatures, often at 5000K and above, yield a crisp, bluish-white illumination. Deliberating on the color temperature offers you the freedom to sculpt your ambiance according to your aesthetic preferences and intended use.
Wattage Equivalence
Energy-efficient light bulbs often provide a wattage equivalence metric to guide users transitioning from conventional incandescent bulbs. For instance, an LED bulb consuming a mere 10 watts might be presented as an equivalent to a 60-watt incandescent bulb. This relatable measure aids in gauging the energy consumption and performance of the bulb, facilitating a seamless switch to more efficient alternatives.
Dimmer Switch Compatibility
If you envision employing dimmer switches to control the lighting atmosphere, it's imperative to verify that the selected energy-efficient bulb bears the “dimmable” label. Not all bulbs possess this attribute, and compatibility with dimmer switches is contingent upon this designation. Ensuring dimmer compatibility secures your ability to modulate lighting intensity and mood according to your preferences.
Halogen Incandescents
These have a capsule insight that holds gas around a filament and this increases the efficiency of this bulb. These are available in all sorts of shapes, you can get different colors and even dimmers if you like.
They meet the federal minimum energy efficiency standards. However, there are better options now that can be better for your lighting needs.
CFLs
The full name of these is compact fluorescent lights similar to the straight long tube fluorescent lights that are usually found in the kitchen or in the garage or basement.
They are usually curly and use less electricity than typical CFLs They can pay themselves off pretty quickly, but they are quite expensive at the outset. They can start saving you money after nine months. It actually uses one-fourth of the energy that traditional bulbs use and it can last ten times longer for the same amount of light.
You can find them in various different colors like warm tones. When they first came out, one of the biggest problems people had with them is that the light they gave was too cold. However, new CFL bulbs can actually give a warm light and save you money.
Some of the CFL bulbs are encased to cover a wider area with the light so that they can provide a similar shape of the bulbs that you are replacing.
You can also get the dimmable option which is great. You should always recycle them as they contain a small amount of mercury and many companies recycle them for free.
LEDs
Light emitting diodes contain semiconductors that convert electricity to light. It was once known only as the type of light used in indicators and traffic lights in white light and other general illumination.
However, today it’s one of the most common energy efficient technologies and it’s developing very quickly. They have an energy star and they use only about 20% – 25% of the energy, while lasting 15 or 25 times longer than the traditional bulbs.
They are now available in many different products as replacements for traditional bulbs, reflector bulbs, small track lights, desk lamps, kitchen lighting under cabinets, outdoor area lights, and so on.
They come in a wide variety of colors as well as dimmable options just like motion or daylight sensors.
They work equally well indoors and outdoors because they are extremely durable and great performance in different environments. You can find great outdoor options which are very popular right now like pathway lights, step lights, porch lights, and solar-powered LED lights for even more efficiency.
LEDs are more expensive in general but they still save money and last a long time. The durability itself saves a lot of money.
Benefits Of Energy-Efficient Light Bulbs
The benefits of energy efficient light bulbs may be quite obvious but you should still be reminded of what they are before you make any big decisions. For one, they require much less energy to work properly. Here’s a look at what other benefits energy efficient light bulbs can bring us.
Efficiency
This is a bit obvious, and we mentioned it earlier, but it’s worth mentioning again. For comparison, CFLs are four times more effective than traditional bulbs, lasting ten times longer too. LED bulbs can work 24 hours a day, 7 days a week for 11 years.
Using them also cuts your energy bill a lot. This means that you can save both on the lifetime because in 11 years you would buy countless regular bulbs but just one LED, and your electricity bill will be lower.
Lower emissions
Every bulb you replace with an energy efficient one, will reduce the emissions by half a ton. If every person in the US replaced just one bulb, the emissions reduced would equal the number of emissions from 800 000 cars on the road. Imagine how much of a difference you could make.
Electricity savings
Energy efficient bulbs cost more at the outset than the traditional incandescent bulbs, these will offer valuable savings later on, over their lifetime by lasting longer and using less energy.
Versatility
The energy efficient bulbs can now replace almost any incandescent bulb, which is amazing and really useful in many homes. There are CFLs that can work on dimmer switches and on three way lamps and so on.
Durability
LEDs can take a lot of stress from bumping and weather. They don’t need a filament so they don’t break as often as your regular bulbs would.
In essence, there is no reason not to get these energy efficient bulbs as they can save you a ton of money. Depending on the provider, the price can be a little higher in the beginning but it makes up for it later on.
