Best smart light bulbs
Smart bulbs are brighter and easier to control than ever, but choosing the right one is a challenge. CHRISTOPHER NULL reports
Smart light bulbs – LED-based bulbs that can be controlled by a hub or smartphone app – are no longer a new idea. What is new is how far this technology has come since its advent just a few years ago. Also new: Products from companies such as Nanoleaf (fave.co/2NYcJ5z) fundamentally change the light-bulb concept.
Smart LED bulbs aren’t quite a commodity, but they are getting close to maturity as far as the
market goes. Today’s bulbs are more compact, much brighter, have better colour representation, and, for the most part, feature control apps that do more than ever and are easier to set up. Prices have also come down, with some no-name colour-tunable bulbs now available for less than £10 each. (Buyer beware: you get what you pay for.)
Smart light bulb protocols and features
Three control technologies continue to vie for leadership in the smart bulb market (Z-Wave is a major contender in smart lighting, but you won’t encounter it in bulbs – just in switches, plug-in modules, control panels, and smart-home hubs).
Zigbee: Bulbs that use the popular smart-home networking protocol require a bridge to communicate with your home Wi-Fi network. This is the technology Philips’ Hue Line-up uses, but it’s not the only one.
Wi-Fi: This class of bulb talks directly to your Wi-Fi router, no hub or bridge required. LIFX and TP-Link both manufacture excellent Wi-Fi smart bulbs, but neither company comes close to the Hue line-up in terms of the depth and breadth of the Hue ecosystem.
Bluetooth: These bulbs skip your home network altogether and pair directly with your smartphone or tablet. As such, they can’t be controlled from outside your home. GE and a number of other manufacturers make Bluetooth bulbs, some of better quality than others. Signify has recently added Bluetooth radios
to its Philips Hue line of smart bulbs, which eliminates the need to deploy the Philips Hue Bridge. Taking the bridge out of the equation reduces the overall cost of deployment, but adds some limitations. You can read more in our review of the new Philips Hue bulbs.
Each of these technologies has pros and cons, so before you attempt to settle on a specific bulb, first try to determine which tech is right for you. If you want to hook your bulbs into a broader smart-home system – such as SmartThings or Nest – Bluetooth bulbs are out. You can control more than one bulb with your phone, but you can’t connect it to sensors or other systems inside your home. Don’t like the idea of pairing a bulb to your phone? A Wi-Fi bulb will work best for you, though you won’t have quite as many options as you’ll find with a Zigbee product.
Smart bulb, or smart switch?
There’s a significant argument about the best way to install smart lighting, and two approaches present themselves. You can either go with expensive smart bulbs and control them all
individually, or you can use cheap dumb bulbs and install smart switches to control all the lights on that circuit. Both approaches make sense: With smart bulbs, the biggest issue is cost, but there’s also complexity to deal with. While bulbs can usually be grouped based on location, this is only as intuitive to manage as the bulb control app.
Smart switches, on the other hand, are far more complicated to install – to the point where some users might be uncomfortable dealing with exposed wiring and would prefer to hire an electrician. Smart switches, however, provide more flexibility in many installations.
Habituated from years of flipping hard-wired switches, many users (or their children) will instinctively use the wall switch to turn the lights out when they leave a room. Once that happens, all the apps in the world won’t be able to turn the light back on until the switch is returned to the on position. While this won’t be an issue if you install smart switches, they can’t change a bulb’s colour or colour temperature.
That said, smart bulbs, no matter what the technology, still won’t be right for everyone. Notably, most of these bulbs cannot be dimmed via a hardwired wall switch (it messes with the power going to the radio, rendering them useless). Some will fail even if a dimmer is present on the circuit and dialled up to full power. The quality of light from an LED bulb is likely to be much, much better.
The good news is that bulb prices are going down, so it’s easier to get started with smart bulbs and less punishing should you find that a product doesn’t work for you. That said, we want to get you started on the
right foot. So without further ado, here are deep dives into the most worthwhile colour and white LED smart bulbs on the market.
White LED bulbs are smart, too
With their rainbow of hues and myriad party tricks, colour LEDs get all the press in the world of smart lighting. It’s fun stuff, but the reality is that most of us will rarely find much of a need to turn all the lights in the house blue or red – unless it’s time to celebrate our team winning the Premier League. Even then, you’ll probably want to turn them all back to white after the celebration.
White light is also important in its own right, as today there is plenty of science to show how various
shades of white – with variations in colour temperature – impact our psychological state. Cool light that’s closer to blue has an energizing effect, and is best in the morning. Warm light is relaxing, and is best after the sun goes down. Note, however, that not every white LED smart bulb is colour-temperature-tunable. Check out the specs before you buy.
White smart bulbs downplay the party features that are a staple of colour-tunable bulbs. On the other hand, white smart bulbs are less expensive than colour bulbs, making it more affordable to roll them out in multiple rooms.
Best colour LED smart bulb Philips Hue White and Colour Ambiance A19 (Bluetooth + Zigbee)
Price: Varies. See fave.co/2VKWWM1
Philips was one of the first players in this market, and the company’s experience shows. Physically, its Hue Colour and Ambiance bulbs haven’t changed much since their introduction in late 2012, but the latest generation lasts a lot longer and the company has added a Bluetooth radio that obviates the need for the Philips Hue Bridge (but most smart home denizens will want the Bridge anyway). The Philips Hue ecosystem is the industry’s deepest and broadest, including not only bulbs of every shape and size imaginable, but also indoor and outdoor fixtures as well, including the Philips Hue Calla pathway light and the Philips Hue Lily outdoor spotlight, both of which we like very much.
Best white LED smart bulb Philips Hue White BR30 (Bluetooth + Zigbee)
Price: Varies. See fave.co/2VKWWM1
Our choice won’t surprise anyone who’s been following this market. Philips dominates this space and is also our top pick for best colour LED smart bulb. The latest Hue bulbs can be controlled via Bluetooth or Zigbee (the latter requires the Philips Hue Bridge), they deliver high-quality light, and are backed by a strong warranty. We received the BR30 form factor for our review, but the bulb is also available in A19, candelabra, and even with vintage-style LED filaments.
