What are Smart Lights bulbs?

*Women Controlling Smart Light Bulb with a Mobile Application*

Smart light bulbs are LED bulbs with advanced lighting technology. These bulbs can interact with the environment and users around them and adjust their color, brightness, and temperature accordingly.

Smart light bulbs designed to connect with wireless technologies such as Wi-Fi, Bluetooth, or Zigbee. This means you can easily control them with the help of a remote control, smartphones, or even voice assistants (Alexa or Google Assistant). This connectivity also helps you control and manage smart lighting while you are away from home.

For example, you can adjust the lighting of your study room to bright white for better concentration or turn your bedroom light to cool blueish by simply using your smartphone or voice assistant (Alexa, Google assistant).

Unlike traditional lighting, smart light bulbs go beyond just lighting a space. You can save on energy costs by creating a lighting schedule for your house, such as the lights should automatically turn on and off at certain times of the day.

How do Smart Light Bulbs Work?

The 'smartness' in smart lighting comes with their ability to connect with other devices. These bulbs have a microchip that can connect with different wireless connections. There are different types of wireless systems that can make a lighting fixture smart. We will discuss some of the most commonly used technologies in residential smart lighting.

Bluetooth

Bluetooth is one of the most common wireless technologies for exchanging data between devices. Anyone can easily access it, but it has a very limited data storage capacity. You can only use Bluetooth between limited distances. This means it is good for managing a single room's light or AC with your phone but will not work well through the walls.

Wi-Fi

Wi-Fi is the most popular technology used for smart lighting or home automation. It uses a LAN (local area network) to provide internet connectivity within a certain range. You can use a router to connect and control all smart devices from a single network, such as lights, doorbells, speakers, or smart locks. As compared to Bluetooth, Wi-Fi has a better distance range (150 to 300 ft) and high-speed data transfer. The downside is that it has a high electricity consumption and the lights wouldn't work when the router is down.

Zigbee

Zigbee is a wireless communication system that carries small amounts of data over short distances. It is a mesh network where every node in a network is connected and interacts with other devices for data exchange. It does not require any internet connection, which means your smart home will function perfectly even if the internet goes down. Zigbee is a low-power, low-cost, and easy-to-use system. The only disadvantage is its short range (100 ft max), which is unsuitable for commercial or large-scale automation.

To understand how do smart light bulbs work on different networks, their power consumption, and suitability, let's do a complete breakdown:

The table above shows how three common wireless technologies work with smart lighting. Bluetooth offers a simple control for nearby rooms, whereas Zigbee supports multiple device setups with reliable communication. However, Wi-Fi offers the best support with faster data transfer, which makes it a suitable choice for smart lighting.

Important Considerations for Choosing Smart Light Bulbs

You should consider a few features and settings before choosing smart lighting for your house. Below, we have listed the most prominent ones.

Compatibility

Before buying smart light bulbs, check their compatibility with your existing smart home systems and other devices. Most of the smart home systems require all connected devices to use the same hub. Also, ensure the bulb connects with your existing Wi-Fi or needs an additional hub to function.

Brightness and Colors

This is the best part about choosing smart lighting. Choose from a brand that offers variation in brightness and color temperature:

Lumens: Lumen measures the brightness of a bulb. A higher lumen value means brighter light output. For instance, a bulb with 600 lumen will shine more than the one with 400 lumen. Consider the size and purpose of the space and then choose accordingly.
Color Temperature: Color temperature defines the warmth or coolness of light; it is measured in kelvin. Light fixtures with lower kelvin (2000 to 3000) indicate warm-yellowish light, while higher values ( 4000 to 5000) and above move towards white and cool bluish light. Choose from a brand that offers variation in color temperature.

Energy Efficiency

Generally, all smart LED bulbs are designed to be energy efficient, with an average lifespan of up to 50,000 hours. Choose a bulb that consumes less energy and has a higher lifetime to save money in the long run.

Size

Smart bulbs come in different shapes and sizes and are usually identified by their base code. Before buying, measure the exact diameter of the screw base of your light fixture. This will help you determine the appropriate bulb code. Most of the smart bulbs come in standard sizes like:

A 19: This is the most common size, similar to a regular incandescent household bulb.
BR 30: It is a wide bulb with a reflector, often used in recessed lighting cans.
E26: This is the base size for a smart bulb in a lamp.

Installation and Setting of Smart Lighting

Installation of smart lighting can be done in two ways. First, if you are planning a complete home automation, consult a professional team with dedicated expertise. These people have the right support and technical knowledge to set up a complete home automation system that comprises lighting, security, entertainment, or climate control of your house.

Second, if you are only planning to update your existing light fixtures to smart ones, this is a small DIY project you can easily do over a weekend. Here is a quick guide for how you can install and set up smart lighting in your house:

Preparation

First, ensure the smart bulbs you buy fit your existing light fixtures and work with the Wi-Fi. Go to the app store and download your manufacturer's application.

Installation

Turn off the power at the circuit breaker. Remove the old bulb from the socket and fix the new smart bulb securely. Once the bulb is installed, turn on the power.

Connection and Control

Open the manufacturer's app you have downloaded earlier. This app will guide you through setting up a smart bulb. This might involve connecting to the Wi-Fi and naming your bulb ( dining room lamp) for easy identification. Once connected, use the app to turn the bulb on and off and adjust any features ( dimming, color change) to confirm everything is working smoothly.

Repeat the similar process for each smart bulb you want to install. Explore your app's features to personalize your smart lighting experience.

Benefits of Smart Lighting

Smart lighting goes beyond illumination and offers a variety of benefits to enhance your home experience. Let's see some of the key advantages:

Convenience

The basic goal of home automation is to provide you with complete control and autonomy over your home environment. Smart lighting gives you the convenience to customize your home's indoor ambiance with a single click.

Imagine a remote-controlled light bulb that can be turned on and off with a click or voice command. Modern smart bulbs go one step further with built-in motion sensors for automatic turn on and off. For example, your outdoor smart lights can automatically turn off once you leave the space.

Cost Effectiveness

LED smart bulbs are famous for being energy efficient and using less electricity than traditional incandescent or CFL bulbs. Lighting makes up around 15% of an average house's electricity usage, and LED bulbs can help you save around $ 225 in electricity costs per year. Also, smart bulbs have a longer life span of about 25000 to 50,000 hours, which means you wouldn't need any frequent maintenance or upgrades.

*Energy Savings from Different Types of Bulbs*

Smart Home Integration

While smart lights help you control lighting and save money on electricity, integration with a smart home automation system can take it to the next level. Smart light bulbs' integration with your smart home theater systems and smart climate control lets you create an ambiance and environment of your choice regardless of the time and weather outside. Planning a dinner party at home? Simply tell Alexa to turn the lights bright and play upbeat music on smart speakers. Your home is instantly transferred into a vibrant space for your guests.
