How long does smart lighting last?

When you’re spending a healthy chunk of change on a smart lighting system, you want to know that it will last. We’re here to break down expected timelines for a smart lighting system and figure out which components are likely to fail first.

How long do smart lights last?

Smart lights use LEDs, which reports show last much, much longer than incandescent bulbs. LEDs can last 30,000 to 50,000 hours of output until brightness decreases to 70% of what it initially had. Meanwhile, CFL bulbs will go for 8,000 to 10,000 hours, while traditional incandescent lamps only last 1,000 hours. Applying a little math shows that you could run an LED bulb eight hours a day for 17 years, and even then, you’d only be dealing with a slight diminishment of bulb brightness. If you’re really concerned about making sure your smart lights last long enough, you can always set a schedule so they’re only on exactly when they need to be.

Do smart bulbs burn out?

LEDs will emit less light over time. Rather than burn out from overuse, it’s much more likely that they’ll become unusable due to a wiring fault or gradual decline in color quality before then.

The reason LEDs last so much longer than incandescent bulbs is because they don’t rely on generating heat in order to create light. Incandescent bulbs send their voltage through a filament that gets hot until it starts emitting light as well, but over 90% of that energy is lost as heat. So there’s a lot less stress on the materials at play in an LED, but it doesn’t mean they produce no heat at all. Improper materials that don’t account for the small amount of heat they do produce could result in a burnout. In that vein, LEDs that have been built with poor heat sinks are likely to burn out. Home wiring that’s running at too high of a voltage could equally fry a smart light bulb. There are outliers, however, and in general, you shouldn’t expect your smart lights to burn out in the same way as incandescent bulbs.

Do smart bulbs last longer than regular bulbs?

Smart bulbs do last longer than non-LED bulbs. One potential pitfall with smart lights versus “dumb” LED lights is software support. For example, Philips Hue light bulbs require a wireless hub to communicate with your phone. After a while, the mobile app stopped supporting voice commands to any Hue bulbs that were connected to the first-generation hub, requiring users to upgrade to the next generation. In these instances, the smart light bulbs themselves worked just fine, but the software backbone they needed had partially failed. Basic functions were still supported, but it should be expected that smart lights will lose some of their functions as software platforms evolve.

Do smart bulbs go bad?

At worst, smart bulbs become less useful over time. Diminishing light quality is likely to happen with any LED bulb, and it’s unlikely manufacturers will provide software support for any given product for an indefinite amount of time.

With all of that in mind, hopefully you can pick up a set of smart light bulbs with a clear conscience. These bulbs last a long time, and should serve your home well in providing convenient, colorful lighting. There’s a lot more to LED lighting, though. We’ve got an all-encompassing guide to smart lights that should provide extra background on these products.

Nanoleaf upgrades its music-syncing skills, launches new lighting products at CES 2024
The Nanoleaf Skylight lighting up a room various shades of purple.

Nanoleaf lit up the stage at CES 2024, pulling back the curtain on a variety of new lighting products arriving later this year. Along with the Essentials Matter Smart Multicolor Lightstrip, Outdoor String Lights, and Permanent Outdoor Lights, the company gave fans a closer look at the upcoming Skylight Modular Ceiling Light and the Orchestrator software -- with the latter bringing massive improvements to Nanoleaf's music syncing abilities.

Orchestrator is arguably the most exciting innovation of the bunch, as it connects directly to your computer's sound source to create a highly accurate lighting performance. This allows your Nanoleaf products to create a light show that's more robust than most other products on the market, which rely on sound alone.

A video doorbell is a great upgrade for your front door, allowing you to see (and greet) guests whether you're at home or away on vacation. They also record and store motion events — offering added peace of mind and an additional layer of security to your property.

Today, the best video doorbells include the Google Nest Doorbell, Ring Video Doorbell, and Wyze Video Doorbell v2, among others. While these all offer their own advantages and unique features, they also all capture high-quality footage, are easy to use, and are reliable enough to last you several years before needing to be replaced.

How long does a Ring Video Doorbell battery last?
Person installing Ring video doorbell

A number of Ring’s Video Doorbell models are wireless, including the standard 2020 model, as well as Doorbell 4 and Doorbell Battery Plus. These smart doorbells use battery packs that you periodically remove and charge. The advantage is that you don’t have to worry about wiring projects and can easily place the Doorbell in an optimal position to get the best view of your porch in a do-it-yourself (DIY) project.

But since those battery packs require a bit more maintenance (you’ll get alerts when they need recharging), buyers often want to know just how often they’ll be expected to recharge them and if any long-term replacement costs are involved. Here’s what you should know.
How often does a Ring Doorbell need to be charged?
