Good garden lighting serves two purposes: safety (lighting paths and steps) and atmosphere (making your garden beautiful at night). Together, they extend your outdoor living season by months.
Five types of garden lighting and when to use them
1. Path and step lighting (safety)
LED path lights (£3–10 each, solar or mains-powered) illuminate pathways, preventing trips and falls. Space them 1.5–2 meters apart. Solar versions are cheapest (no wiring), but mains-powered LED lights are brighter and more reliable.
For steps, recessed lights in the tread (the horizontal part) or low spotlights aimed downward are safest. Aim for 50–100 lumens per light.
2. Uplighting (drama and features)
A spotlight pointed upward at a tree, shrub, or wall creates drama and depth. A single uplight on a mature tree: £30–80 for the light, £100–200 to install if wiring is needed. The effect is stunning.
3. Flood lights (broad area coverage)
A floodlight mounted high on a fence or wall lights a large area (garden party, kids playing). 400–800 lumens typical. Mains-powered floodlights: £40–100. Can be harsh—use a dimmer or filter for ambience.
4. Festoon lights (ambience)
Decorative string lights hung across a patio or garden structure create warm, inviting atmosphere. 50–100 lumens per bulb. Cost: £50–150 for 10–15 meters of string.
5. Deck and feature lights (accent)
Recessed lights in decking, low-voltage lights in borders, or wall-mounted lights on garden structures. Often dimmable or color-changing. Cost: £20–80 per light depending on sophistication.
Design principle: Layering
Like kitchen lighting, garden lighting works best in layers:
- Ambient: Soft general light (festoon strings, one large uplighting upward).
- Task: Path and step lighting (safety).
- Accent: Spotlights on features (trees, sculptures, water features).
Solar vs. mains: Pros and cons
Solar: No wiring, zero running cost, simple installation. Downside: dimmer, must be in sunlight to charge, batteries degrade over time (5–7 years).
Mains: Brighter, more reliable, can be on timers and dimmers. Downside: wiring needed (cost and disruption), electricity cost (~£10–20/year per light), building regs approval.
Recommendation: Use solar for path lights (low-power, pure safety). Use mains for uplighting and feature lights (where brightness and reliability matter).
Color temperature and intensity
Warm white (2,700–3,000K): Inviting, cozy. Best for patios, decks, and entertainment areas.
Cool white (4,000K+): Clinical, harsh. Avoid for ambience; okay for security if you prioritize visibility over warmth.
Avoid bright white flood lights unless you’re lighting a large area for a party. Dimmers let you adjust intensity.
Installation considerations
- Power source: Solar is DIY. Mains requires an electrician and building regs approval for hardwired systems (but low-voltage systems under 50V are exempt).
- Cable routing: Mains cables should run under the ground in protective ducting. Cost: £200–500 for a 20m run.
- Outlet location: Position a weatherproof outdoor power socket near your garden so you can plug in lights or power tools. Cost: £100–200.
Cost guide for a typical garden scheme
- Solar path lights (10 lights): £30–100.
- Mains uplighting (3 spotlights): £300–500 including installation.
- Festoon string (15m): £50–150.
- Outdoor socket and wiring: £100–200.
- Total: £500–1,000 for a well-lit garden.
Maintenance and longevity
LED lights last 25,000+ hours (25+ years). Solar batteries degrade over 5–7 years (replace them for ~£10–30 per light). Mains-powered systems are virtually maintenance-free if wiring is protected.
Smart and color-changing lights
WiFi-enabled garden lights (Philips Hue, LIFX, etc.) let you change color and brightness from your phone. Cost: £30–100 per light. Worth it if you entertain frequently or like to adjust mood.
Bottom line: Layer your garden lighting: solar path lights for safety, mains spotlights for drama, festoon strings for ambience. Total cost: £500–1,000 installed. The result is a garden that’s beautiful, safe, and usable from dusk onwards.
