How long do Philips LED lights last?

LED light bulbs are already supposed to be energy-efficient, but Signifiy thinks it can improve on the formula. The company has released Philips Ultra Efficient LED bulbs that, as the name implies, use 40 percent less energy than the brand's usual LED options. The "advanced" LEDs and optics reduce the yearly energy cost to between 55 cents and $1.03 per bulb, Signify claims. For context, a Philips Ultra Definition 60W bulb uses an estimated 97 cents each year.

The new lights might also be helpful if you're trying to minimize waste. Signify estimates that the Ultra Efficient line has an average lifespan of 50 years, or more than three times the usage of Philips' standard LED bulbs. There's a real chance this lighting might outlive you.

The Philips range is available now as a Walmart exclusive. It starts at $10 for a 60W-equivalent A19 bulb ($17 for two) in soft white and daylight variants. A 65W BR30 bulb costs $11, while a 100W A21 light is $15. You're paying considerably more than you would for standard LEDs — a four-pack of Philips Ultra Definition 60W bulbs costs $14. However, Signify is clearly betting that the lower energy costs and increased longevity will ultimately save you money on top of being kinder to the environment.

The catch, of course, is that these aren't smart bulbs. You'll need to live with higher energy consumption if you insist on Philips Hue and don't want to use smart plugs. If that isn't an obstacle, though, you may see your energy bills shrink if you replace enough bulbs around your home.

How long do smart bulbs last? A fair question to ask if you're about to invest in a home-wide revamp of your lighting setup. Or, indeed, if it's just one bulb you want to replace as these are more expensive than their simpler filament bulb siblings.

This guide aims to clarify just how much glow you can expect for your buck. So even if you don't go for one of the best smart light bulbs, you can still have an idea of what to expect and – crucially – what to look out for and to avoid when buying.

To be clear, smart light bulb means an LED bulb or light strip that smart connects to a device. That can be using WiFi and a hub or directly to a phone using Bluetooth. These factors can vary the features you get and the way you use them but they won't change the lifetime. That comes down to other factors that we go into below.

How long do smart bulbs last compared to filament?

Getting an automated home is one big draw when it comes to smart light bulbs but the other is just how much you get for your money. The key here is that traditional bulbs use lots of power and have a limited lifetime. Smart bulbs, on the other hand, use LEDs instead.

An LED uses very little power compared to a bulb. Have you ever turn off a gadget and noticed the little light is still on? Yup, even without power they keep going, they're that efficient. 

As a result you can expect a very long lifetime from your smart bulb. The average will last around 23,000 hours. For a six hours day, or night, of being on that's about ten years of life.

Go for the top end models like Philips Hue or the Lifx range and they offer up to 25,000 hours which, with similar use, is an 11 year life. Or to put it another more realistic way, with three hours use a day on average these will last 22 years.

Is there more to go wrong with a smart light bulb?

The short answer is yes. Automated lighting not only illuminates a room but also let you smart control them for features like color variations, timers, automated power based on other gadgets' actions and so on. The point is there is more connectivity and gadgetry to go wrong. That said you do get a two year warranty on brands like Philips – not that this helps much in that decade long expectation of bulb life.

The other factor, that isn't about lifetime, is that these use your WiFi – in most cases – and can potentially create an opening for network attacks. This is very unlikely and you can take steps to protect yourself, like using a VPN, but it's worth noting.

Are standard LED bulbs longer lasting than smart bulbs?

While comparing standard filament bulbs to smart LED light bulbs does make the latter look amazing for life, you can also get standard LED bulbs. 

A smart LED bulb, at its best, is going to give up after 25,000 hours. By comparison a cheaper LED bulb, with no smart features, is going to keep going for around 50,000 hours.

So if you want longevity over everything else, go for a standard LED. But if you need smart features and think the price is justified by those extras then smart is the way to go.

Why do LED bulbs burn out?

LED bulbs might be wonder lights that last for ages, change colors and work instantly, but even they have a lifetime. But why? These Light Emitting Diodes (LEDs) gradually get dimmer over time.

While LED bulbs create very little waste and so produce nearly no heat, there is still some produced. This gathers in the bulb neck and can get hot which raises the temperature of the air in the bulb itself. This is where some of the diodes die. Eventually as more and more drop off you'll notice the light getting less and less bright.

So the advantage here is that the LED bulb won't just die like a traditional bulb, leaving you in the dark. But the downside is you will have to spot when it's not good enough and needs replacing. 

How can I make my smart light bulb last longer?

There are a few ways to make sure your smart bulb gets the best shot at its little life possible. As mentioned it's mostly about avoiding overheating. So if you have your bulb on constantly it'll get hotter than if you give it breaks. So perhaps turning the bulbs off when you leave the room and on when you return could be a helpful step to extend its lifetime.

Another cause of overheating is loose connections. So the first step is to make sure it's screwed all the way in. Next is to make sure the connections are clean, with no corroded contacts on the fitting the bulb is going into.

Make sure the fixture the bulb is going into is big enough and there's enough space to let air flow. Ventilation is key to make sure the bulb stays as cool as possible and lasts longer.

Lastly, be sure to set timers. That means when you're not using the bulbs, even if you forget to turn them off, they'll power down – ensuring you get the most hours of use in the longrun.

As with all smart tech, occasionally things go wrong. You may find it useful to know how to reset a smart bulb.
