Solar Outdoor Lights: How to Choose the Right One
Share
Solar outdoor lights charge from the sun by day and light up at night, with no cable to run and no electrician needed for most models. The right one depends on the job: lighting a path, securing a side passage, marking a gate post or flooding a driveway. This guide explains what to compare, then matches each job to lights from our range.
1. What to compare on a solar light
- Lumens: how much light it gives. Compare lumens rather than watts. Our solar lights range from around 300 lumens for a lantern to 1,500 lumens for the largest solar floodlight.
- Sensor: many solar lights switch on fully only when they detect movement, which makes the battery last through the night. Each listing gives the detection range.
- IP rating: how well the light is sealed against dust and water. IP44 resists splashing, IP54 adds dust protection for exposed walls and garden beds, and IP65 is sealed against water jets for fully exposed positions.
- Battery: where the listing gives it, a larger battery (shown in mAh or Ah) stores more of the day's charge.
- Panel position: built-in panels need the light itself in sun. A separate panel on a cable lets you mount the light in shade and the panel in sun.
- Colour of light: 3000K warm white for gardens and entrances, 4000K neutral white, and 6000K–6500K daylight for clear visibility on driveways and for security.

| Patio table, camping, a light you can carry | Synerji solar LED lantern | 300 lumens, solar or USB-C charging, up to 48 hours lighting time |
3. Placement makes the biggest difference
A solar light is only as good as the sun its panel gets. Mount the panel where it gets direct sun for most of the day, away from roof overhangs, trees and walls that cast shade. If the spot you want to light is shaded, choose a light with a separate panel, such as the Synerji solar floodlight, so the panel can go where the sun is.
Expect shorter run times in winter, when days are shorter, and wipe the panel clean every few months so dust does not cut the charge.
4. When solar is not the right choice
If the area is in shade all day, or you need bright light all night rather than when movement is detected, a mains-powered light is usually the better option. Our outdoor wall lights and LED floodlights include sensor models; these need to be installed by a qualified electrician. For a fuller comparison, read solar vs rechargeable lights.
Frequently asked questions
What are the best solar outdoor lights for security?
Choose a motion-sensor model with daylight (6000K–6500K) light and at least 700–1000 lumens, such as the Synerji twin solar sensor light (1000 lumens, 10m detection) or the 8W rectangular sensor wall light (1000 lumens).
Do solar lights work in winter?
Yes, but they charge less on short or cloudy days, so run time is shorter. Placing the panel in full sun helps most.
Do solar lights need an electrician?
Most solar wall, spike and post lights screw to a wall or push into the ground with no wiring. Mains-powered outdoor lights do need a qualified electrician.
What does IP54 mean?
The light is protected against dust and splashing water from any direction, which suits exposed outdoor walls and garden beds.
