Security lights are simply floodlights with a motion sensor that switch on when movement is detected, and switch themselves off again when no motion is detected for a set period of time, usually between ten and 30 seconds. Wireless security lights appear to be a very affordable, convenient and versatile solution; but are there any downsides to them? This article will look at the pros and cons of wireless security lights compared to their mains powered counterparts.


Perhaps the biggest advantage of wireless security lights is their convenience. They are easier to install and more versatile than mains powered security lights, which will need to be either installed by a qualified electrician, or plugged into a mains outlet. With wireless, you can install the light yourself quickly and easily; and because they are wireless, you can install them on any surface you can screw them to, without remaining in close proximity to an electrical supply.

Power and consistency

The major strength of main powered security lights is their consistent, high quality light output. Because they are have a steady supply of electricity, their light output remains the same over time, whereas with wireless lights that rely on batteries, at some point the light produced will diminish. Similarly, because mains powered lights receive more power from the mains as opposed to batteries, they produce a much higher light output, illuminating dark areas more effectively.


Taking into account the cost of the light and installation, wireless security lights come out cheaper than wired lights. Of course there are different types of security light in both categories at different price points, but wireless tend to be cheaper overall.

Should you choose wireless security lights or mains powered?

The answer to this question depends on three things: 1. The area to be illuminated in terms of size 2. The proximity of a mains electricity supply 3. Budget and time constraints


Mains powered security lights produce more light than wireless, so if you need to light up a large area, a single mains powered light will be the equivalent of two or three wireless lights. Use wireless security lights for driveways and small yards and gardens. For areas larger than this, either use mains powered or more than one wireless light.

Proximity to mains power

This is a big consideration. The further away from the mains power supply the location of your light needs to be, the more expensive and inconvenient it will be to install a mains powered light. It may be cheaper to install a few wireless lights rather than a single mains powered one.

Budget and time

If you need a quick fix then wireless security lights are the way to go. They can be installed in minutes on walls, fences, sheds or trees. If you have the time and budget, and you want the higher light output that mains powered security lights provide, then they are clearly the way to go. So, when deciding on whether or not to use wireless security lights over their mains powered equivalents, consider the points above to find the right solution for your needs.
