Smart LED Light Bulb in Hand

There is no denying that smart lighting is gradually but certainly replacing conventional and traditional lighting systems. And it is proving to be more than just a fancy way of controlling the lighting within your home. Nonetheless, this is a relatively new concept to a huge portion of the population; hence the need for this comprehensive guide to smart light bulbs.

What is a Smart Light Bulb?

A smart light bulb is an advanced LED bulb that is controllable and customizable via wireless communication standards. Since they use light-emitting diodes (LED) in place of conventional filaments, smart light bulbs last must longer. They also use considerably less electrical energy than their traditional light bulbs.

How do Smart Light Bulbs Work?

Through applications on your smart devices such as a smart speaker (Amazon Alexa, Google Home, Apple Homekit, etc.), smartphone, or tablet, smart lightbulbs can be controlled (including voice control), automated, and customized to the needs and preferences of the user(s). The wireless communication pathway can be realized either via Wi-Fi, Z-wave, ZigBee, or even Bluetooth wireless communication technology.

Some brands, for instance, the Phillips Hue, require an additional special gateway known as a hub for their smart light bulbs to work. The Hub or gateway is a separate unit that relays commands and instructions to the smart light bulbs. At the core of this assembly is a native application installed on the smartphone or onboard the home automation hub where a user can control the different aspects of the operation of the smart bulbs.

Some of these aspects revolve around the following:

  • The ability to remotely and conveniently adjust the level of brightness of the bulbs in your home or office from anywhere. This also includes the luxury of switching off/on the bulbs without necessarily being physically in that room or even when away from home.
  • Setting up an automated home or office lighting schedule tailored to your lifestyle. You can also schedule the smart light bulbs to switch on or off at a specified time.

Do Smart Light Bulbs Need Hubs?

Some smart light bulbs require a hub while some don’t. Not all smart light bulbs today require a special hub/gateway to controlled via wireless connectivity. The smart light bulbs that don’t require a hub simply operate over the standard wireless communication protocol (e.g Wi-Fi or Bluetooth). A good example of such a smart light bulb is the LIFX A19.

How do smart bulbs work with switches?

Smart bulbs are usually pre-programmed to work with conventional switches the same way a regular light bulb would. This implies that even without utilizing the advanced features of wireless connectivity and the full potential of smart bulbs, they can work just as well as your conventional bulbs do.

The catch, however, is that the operation of the interconnected wireless lighting control system assumes that all switches are in the ‘ON’ position when issuing commands. In other words, when you physically turn off the lights, they will stay electrically off until you turn the physical switch on again to allow the flow of electricity.

There are also smart switches which are a cheaper alternative to smart light bulbs. A smart switch works similarly to a smart light bulb in that it can be controlled via wireless connectivity. Therefore, because you have far fewer switches in your home than you do light bulbs, replacing all the regular switches in your home with smart switches is a much cheaper option than replacing every regular light bulb in your home with a smart bulb.

Are smart light bulbs safe?

There are growing concerns about the vulnerability of smart home automation systems to hackers with malicious intent. The argument is that smart light bulbs, speakers, and other smart devices that wirelessly connect to your home’s network can create vulnerabilities that can be exploited by hackers.

As such, a hacker who can infiltrate his/her way into your home’s network, can turn off the interconnected alarm system and unlock your doors to facilitate a ‘smart break-in’. Fortunately, there are numerous ways to mitigate these security risks. Such as hiding your home network and using a secure WPA network access password. Also regularly updating the security features of your smart devices.

Do Smart Light Bulbs Save Money?

Yes, smart light bulbs do save money. This is due to the fact smart bulbs utilize LED technology, which makes them far more efficient than traditional incandescent bulbs. As a result, they use less electricity and last much longer, saving you money on both electricity and replacement costs.

But the savings don’t end there. For example, how many times have you forgotten to turn off the lights when walking out of a room? Probably too many to keep count. These are the little things/habits that eventually rack up your energy bills. Luckily, most smart light bulbs can be controlled via the app on your phone. So even if you forget to turn off a smart bulb, you can always turn it off via your phone even when you are away. And don’t worry, as smart bulbs consume very little electricity (essentially negligible) when off or on standby position.

Do smart bulbs work in any lamp?

Smart light bulbs can be used in any lamp or fixture as long as the bulb’s base is electrically compatible with the socket of the fixture. However, if a smart bulb is not compatible with a particular lamp or fixture, a smart plug may be the better alternative. A smart plug used with a fixture containing a regular non-smart lightbulb will allow you almost the same control, flexibility, and luxuries of wireless connectivity to your smart devices as you would have with a smart bulb. Smart plugs can also be used to monitor the lamp’s energy consumption. Though you won’t be able to adjust the brightness of the regular bulb or utilize the multicolor capabilities of smart bulbs.
