A smart bulb resembles a simple LED bulb, but it is controlled using smart devices or technology. Smart light bulbs are expensive compared to traditional bulbs; however, they require less energy and serve you in the long run.

Smart bulbs come in various sizes and color-changing features, so you can pick the one that perfectly blends with your indoors.

Advantages of Smart Light Bulbs

Here are the advantages of installing smart light bulbs in your home:

Easy Operation

Compared to many other innovative lighting solutions or devices, a smart light bulb is very easy to operate. There's no need for complicated connectivity and installation, as you can use competent assistance or a smartphone app to run the bulb. Once you've installed the bulb, you can pair it up with your wireless internet connection.

After a successful connection, it gets easy for you to control it through your phone or voice control. However, if you have bought a specific brand of the smart light bulb, then it may need a particular gateway or hub. For instance, if you've just got your hands on a Philips Hue smart bulb, you need a Philips Hue Bridge for its successful operation.

Longer Life Span

Typically, an incandescent bulb has an average lifespan of 750 to 2000 hours. But, as smart bulbs are either LED or CFL bulbs with integrated smart technology, their lifespan comprises over 350000 to 50000 hours. This means once you've installed smart light bulbs in your home, you can use them for as long as 20 years which is a lot more than the cost.

Better Security

Another benefit of smart light bulbs is that they make your home more secure. A smart bulb has sensors that detect the presence of someone in your room and gets turned on and off automatically. You can also use this feature to send alarms on your phone when you are away from home to ensure no one's entering your space.

Disadvantages of Smart Light Bulbs

Let's have a look at a few of the smart light bulbs disadvantages:

Needs Bridge for Higher Demands

If your smart light bulb usage is more than average or you need high voltage output, it'll not work with ordinary hubs or devices. Instead, you need to buy a separate bridge to meet the higher lighting demands of your home.

Light Switches Must be On

To operate your smart light bulb, it's essential to keep the light switch connected to it always on. It's because once you turn the switch off, you won't be able to operate the bulb through any smart device. 

So, if you are looking for something to minimize your light and energy usage, a bright light bulb is the ultimate choice. It allows people to control the device through different options like manual or voice control and is a perfect smart home lighting package for those who want something easy-to-use and long-lasting.

Smart Bulb vs Smart Switch: What is a Smart Light Switch?

A smart light switch is also a wireless-enabled smart device that allows you to remotely control your home lights. It looks like a standard light switch but has many advanced features like you can control the lighting using your smart device or a voice command. Besides lights, an intelligent switch allows you to manage all other devices or equipment connected to it.  

For instance, if the wireless light switch is connected to the fan or fireplace and lights in the same room, you can turn them on remotely through that switch. What's the best part? A wireless light switch lets you create custom schedules to turn it on and off at specific times. Moreover, with it, you can manually turn the switch on or off using a smartphone when away from home.

Advantages of Smart Light Switch

Here are the advantages of wireless light switches that you should know before it's installed in your home:

Very Convenient

A smart or wireless light switch is very convenient as you can control it anytime and anywhere as long as it has a steady internet connection. For instance, if you are out on vacation, you can schedule when you want your home lights to be on and off with your smartphone to save on your energy bills. This is something that you can't achieve with a traditional light switch.

Multi-Device Integration

As a wireless light switch is a quick way towards home automation, it enables you to control multiple devices remotely and manually. For instance, a smart switch turns on alarms, door sensors, and lighting before the arrival of homeowners.

Variety of Options

Another exciting advantage of the smart light switch is that it comes in various sizes and types. The main types are dimmer, motion sensors, rocker buttons, etc. So you can select the desired one matching your needs.

Need Different Models for Different Setup

To make your wireless light switch two-way or three-day, you need to go with a specific model. It's because not all switches are designed for multi-way operation. For example, if you want a 3-way smart light switch, then Lutron Caséta Wireless Smart Switch is a suitable option.

A wireless light switch is suitable for those who are either building a new home and want home automation or upgrading the old one. For old homeowners, it's not an ideal choice!

What is a In-Wall Smart Relay Switch?

This switch has two parts: a smart relay part and a smart switch part. Connect it with HomeKit WiFi or use any hub like ZigBee or Z-wave to manage all your smart devices and appliances.
