Buying LED Light Bulbs

Buying LED Light Bulbs

It used to be a no-brainer to head to the hardware store for 60-watt incandescent bulbs. But as these bulbs were pushed aside by energy-efficient CFLs and LEDs, buying light bulbs became a bit more complicated.

For example, an LED that’s branded as a 60-watt replacement can draw up to 12 watts and only add about a buck to your energy bill over a year.


When LED bulbs first hit the market, it seemed they were finally going to be the lighting breakthrough we’d all High Bay Sensor been waiting for. They would provide brilliant illumination for a fraction of the energy costs associated with old-fashioned incandescents, and save thousands of dollars on electricity bills each year for businesses.

It’s no surprise that they’re now the go-to light bulb for many homeowners and businesses. They use up to 50% less energy than incandescents and last 50 times longer, which means you’ll spend a lot less on electricity costs over their lifetimes. But what about the cost of an individual bulb? On average, lighting accounts for 10% of a household’s energy usage, so the upfront cost of switching to LEDs can add up quickly.

To calculate the cost of an LED light bulb, start by entering your device’s wattage, which is found on the user manual or on the device itself. Next, enter your price per kilowatt-hour (kWh), which you can find on your utility bill or by using our electricity cost calculator.

You’ll also want to consider the desired brightness of your LED bulbs. Most come in a variety of colors, including soft and warm white, which produce a yellow-tinged, candlelike glow similar to traditional incandescents, and bright white, which is closer to daylight and often used in offices and retail stores.


LEDs are far more efficient than standard light bulbs, which waste about 98% of their energy as heat. This is a major reason why they can last so much longer. They also require a fraction of the power to produce the same amount of light, reducing both energy bills and carbon emissions.

LED bulbs use a semiconductor chip to generate light. When the chip’s negative terminal is exposed to a positive voltage, electrons are drawn to it, creating a flow of electricity that produces light. The resulting heat is dissipated by the chip’s heat sink, which is often made from aluminum or copper to keep the circuitry cool. The better the design of the heat sink, the longer the bulb will last.

Although LED bulbs can be more expensive than traditional incandescent ones, they pay for themselves with reduced energy consumption and a long lifespan. This is why they are increasingly popular in homes, where they can be used to reduce energy costs and fight planed obsolescence and e-waste.

When purchasing LED bulbs, look for information about their lumens (a measure of brightness) printed on the package. The packaging will usually specify an incandescent-equivalent wattage, which is helpful for people who are used to selecting light bulbs by wattage. Also, consider whether the light will be in a closed fixture or an open-air fixture. If it will be in an open-air fixture, the bulb may need to work harder to keep its temperature low, which could shorten its lifespan.


Many LED bulbs are available in a range of colors. Choosing the best color for your home depends on your preferences and the look you want to achieve. If you are shopping for an LED bulb that is a replacement for your existing incandescent or halogen light, start by looking for one with a similar color temperature. For example, 2700K LEDs match the color of old incandescent bulbs, while 3000K and higher are more like halogen light.

If you’re looking for an LED light that changes color, choose a bulb with a built-in diode for each red, green, and blue. The diodes are connected to a control unit that adjusts the current running through them to produce different colors. This type of LED bulb is often called a “colored” LED, and it can be used to add ambiance or to complement the colors in your room.

While LEDs are more energy efficient than traditional incandescent bulbs, they still emit heat. This can shorten the lifespan of a bulb when used in enclosed fixtures. To help prevent this, choose a bulb that is designed for use in an enclosed fixture or install a separate driver to convert the higher voltage AC power supply to low voltage DC for the bulb.

LEDs also have a lower luminous decay than other bulbs, meaning that they don’t lose their light output as quickly. However, they do lose some of their brightness over time. To maximize the lifespan of your LED light bulb, avoid using it in a fixture with too many reflective surfaces or objects. You should also keep it out of direct sunlight to prevent the light from becoming too warm and reducing its efficiency.


The shape of a light bulb can impact its ability to produce light and how it can be used. LED bulbs are available in a variety of shapes, making it easy to find one that will led light bulbs fit your fixtures and complement your decor. They are also compatible with most smart lighting systems, allowing you to control them from anywhere using your phone or computer. If you want to get the most out of your new bulbs, make sure that they are rated for your location and the fixture in which they will be installed.

The first thing to look for when choosing an LED bulb is the shape of the base. There are four primary categories: A-shape, reflectors, decorative, and specialty. A-shape bulbs are most common and can be found in many fixtures. Reflectors are conical in shape and provide a more focused beam of light. Decorative bulbs are smaller and often come in vintage styles to match your décor. Specialty bulbs are used in unique fixtures, like wall sconces and chandeliers.

The other thing to consider is the wattage and energy cost of an LED bulb. The wattage is the amount of electricity that the bulb uses to produce light, and the energy cost is the price you pay per kilowatt-hour for power from your local utility company. Some LED bulbs are certified as Energy Star, which can help you save money on your electricity bill.
