These are great for rooms where you have a feeling that you won't be keeping them there. It's a great alternative for you.
For larger areas or permanent installations, a mains wired LED strip lighting will give you a little more versatility. When you're installing your LED strip lights, you will need a LED transformer. Obviously, this is for the more committed type of lighting.
This is great for accent lighting, or rooms that you know you will keep the lights in. Remember, LED strip lights come in a range of different colours and temperatures. You can even get multicoloured. If this is what you're looking for, mains wired could be a perfect choice.
If you're looking for strip lights for outdoor use, you have to ensure that the LED strip lights have a durable PVC body. Make sure they say that they're suitable for outdoor use, and are impact resistant.
Every single LED lighting strip will state what they are suitable for.
How long do they last?
This is a great question, as they obviously can't be replaced as easily as a bulb or fixture light. In general, LED lights boast a life expectancy of about 50,000 hours - this is around six years of continuous use. Over time, you'll see their output getting a little lower but six years is the general rule of thumb.
For LED strips, you have another factor to consider. Over time, the adhesive strip can degrade and lead to your LED lights falling off your wall or ceiling. For this reason, you need to place them in a safe setting.
If you think these types of lights are for you, then LED is definitely the way to go.
