Philips Hue Low-Volt or Mains Outdoor Lights: What Does Each Need?

Updated

Hue's outdoor range is really two systems. One family is wired into your home's mains like any outside light. The other runs at low voltage from a power supply you plug in, with cable that can run through borders and along paths. They look alike in photos, but they ask different things of your house.

In short

Hue's mains outdoor lights, such as Econic and the newer Semeru and Struana, are 220–240 V fittings that replace an existing outside light on its circuit, and the Class I models need a working earth. Hue's low-volt garden range, such as Lily and Lily XL, runs from a 40 W or 100 W Hue power supply that Hue says plugs into an outdoor socket. A JACK pro in London fits both and can add an outdoor socket on an existing circuit, while a brand-new circuit from the consumer unit goes to a registered electrician.

What does a mains Hue outdoor light need?

It is an outside-light swap with a few Hue-specific checks:

  • An existing outside light on a circuit that can take it. In England, replacing it is not notifiable, and additions to existing circuits outdoors stopped being notifiable on 6 April 2013
  • An earth for Class I fittings such as Econic, Muscari, Struana, the Welcome floodlight and the Secure Flood Light Camera. Some older lighting circuits have none, so the pro runs one or you choose a Class II model such as the mains Impress, Semeru or Scenova
  • A permanent live. The indoor switch has to stay on, or get a Hue wall switch module, or the light drops out of the app
  • RCD protection. BS 7671 expects a 30 mA RCD on new or significantly altered lighting circuits; where a fitting swap meets an older circuit without one, the pro records it and advises an upgrade
  • Signal. The front of a London terrace can be a long way from the Bridge, so a mains-powered Hue light inside near the door helps carry it

Brick and render take masonry fixings, and the cable entry is sealed. In a flat or a listed building, the freeholder's or council's consent comes first. Ask your pro for a Minor Electrical Installation Works Certificate once the light is wired in.

What does Hue low-volt need?

No mains wiring at all if you already have an outdoor socket in the right place. Otherwise:

  • An outdoor socket. Hue's instruction is to plug the power supply into one; where there is none, a pro adds one spurred from an existing circuit, which is not notifiable in England but must have 30 mA RCD protection
  • Room for the plug. Some reviews on Hue's UK pages say the power supply's 13 A plug is too bulky for a standard weatherproof socket, so the pro fits a socket with a deep in-use cover or a weatherproof enclosure
  • A power budget. Add up the watts: Hue says one 40 W supply runs five Lily spotlights or three Lily XL
  • A cable plan within Hue's limits, routed where spades and mowers will not reach it, and in conduit under paving. Hue's UK pages give no burial depth, so this is JACK practice

Fixed low-volt garden lights still count as an electrical installation under Part P, even with no mains wiring touched: not notifiable, but the work must be safe. Hue does not describe keeping the power supply indoors with the cable through a wall, so JACK does not offer that as Hue's method.

When does outdoor Hue need a registered electrician?

Only when the plan needs something new at the consumer unit:

  • A new circuit for garden lights, a shed or a garden room, for example where no existing circuit is near enough or has room for the load
  • A new or replacement consumer unit, including one needed to make space for that circuit

JACK does not book either. The Hue fitting and set-up can be booked through JACK as a separate job once the electrician has finished.

Low-volt suits beds and paths; mains suits the house wall

A rough way to decide:

  • Lighting a wall where an outside light already is: a mains Hue light is the tidier swap
  • Lighting borders, trees and paths across the garden: low-volt, because one plug feeds the run and the cable carries low voltage
  • A roofline or eaves: Festavia permanent, a low-volt system with a 2.5 m lead before the first light, fixed along the fascia from a ladder
  • Lights near neighbours' windows: the Environmental Protection Act 1990 treats artificial light that causes a nuisance as a statutory nuisance, so floodlights are angled to keep their light on your side

What should you send for a Hue outdoor price?

JACK books London addresses only. Send:

  • Photos of each wall or bed to be lit, taken from far enough back to show the route to the house
  • The outdoor socket you would use, or where one could go, and the existing outside light if you are replacing it
  • The indoor switch for the outside light
  • The Hue products, and how many of each

Sockets, enclosures, conduit and extension cables are agreed at cost before you book; JACK does not sell the Hue lights.

Mains or low-volt: how do Hue's two outdoor systems compare?

What your home needsAn existing outside light point, a permanent live, and a working earth for Class I modelsAn outdoor socket near where the cable starts
Cable limitsYour home's existing wiring40 W supply: up to 35 m of cable; 100 W supply: two outputs of up to 30 m each
Hue BridgeRequired for Econic, Impress and Welcome; Semeru, Scenova, Muscari and Struana also list Bluetooth controlRequired
Notifiable in England?No, on an existing circuit; a new circuit isNo, but it is still an electrical installation that must be safe

Hue's power supply pages give a '24 V' lead length but do not state the output voltage in words, so this guide says low-voltage.

How is Philips Hue installation priced in London?

A vetted pro prices your Hue job from the products and your photos, and the JACK app shows that fixed price before you book.

Whether the job touches your wiring matters more than how many lights there are. Fitting B22 or GU10 bulbs, setting up a Bridge and plugging in lamps, Play bars or a lightstrip is set-up work. Ceiling lights, Perifo track, wall switch modules and mains outdoor lights are electrical work on your existing circuits, priced for the isolating, connecting and testing each one needs.

Then the home itself: a heavy fitting that has to go into a joist, a high or sloping ceiling, a two-way landing that needs a module at both switches, old cable with no earth, or a long garden run for low-volt lights. On a high ceiling or a long fitting, your pro can ask another pro on JACK to help through the Pro2Pro feature. Several Hue jobs, and devices from other brands, go on one booking for one fixed price.

You buy the Hue products; JACK does not sell them. Accessories the job needs, such as a deeper back box, an in-use cover for an outdoor socket or aluminium channel for a strip, are agreed and added at cost before you book, and so is parking where it has to be paid for. Prefer to pay for time? As a guide, hourly hire is typically £45–£95 per hour for smart home work and £55–£110 per hour for electrical work, and a full-day handyman booking is a flat £350–£400 for up to 8 hours on site, which suits a whole-house Hue fit.

Frequently asked questions

Do Philips Hue outdoor lights need an electrician?

The mains ones need someone competent to do electrical work, because they are wired into your home. Replacing an existing outside light on its circuit is not notifiable in England, so it does not have to be a registered electrician. Low-volt garden lights plug in, and only adding an outdoor socket for them involves mains wiring.

Can Philips Hue low-voltage lights plug into an outdoor socket?

Yes, that is how Hue says to power them: the power supply plugs into an outdoor socket. Some owners find its plug too bulky for a standard weatherproof socket, so a deeper in-use cover or an enclosure may be needed.

How many Lily spotlights can one Hue power supply run?

Hue says one 40 W power supply runs five Lily spotlights or three Lily XL. The 40 W supply takes up to 35 m of cable, and the 100 W supply has two outputs of up to 30 m each.

Do Hue outdoor lights need a Hue Bridge?

Most do. Hue's low-volt garden lights and established mains lights such as Econic and Impress need one. Some newer wall lights, Semeru, Scenova, Muscari and Struana, also list Bluetooth control and say they work without Wi-Fi.

Can Hue low-voltage cable be buried?

Hue's UK pages give no burial guidance. JACK pros route the cable where digging and mowing will not reach it, and put it in conduit under paving, as their own practice.
