Philips Hue Lily Outdoor Spotlights Installation in London

Updated 1 November 2026

Lily and Lily XL are the spotlights at the centre of Hue's low-volt garden system. They run on Hue's low-voltage cable from an outdoor power supply rather than from the mains, and Hue says a 40 W supply powers five Lily or three Lily XL. A vetted JACK pro in London plans the cable runs, fixes the lights on ground spikes or walls, sizes the power supply and adds everything to your Hue Bridge, for a fixed price you see before you book.

In short

Yes. A vetted JACK pro in London can install Philips Hue Lily and Lily XL spotlights on Hue's low-voltage cable, with the power supply plugged into an outdoor socket as Hue instructs and a Hue Bridge within reach of the garden. If there is no outdoor socket, adding one on an existing circuit is not notifiable in England but needs 30 mA RCD protection, and it is priced into the job before you book.

Product facts come from Philips Hue's UK product pages and support articles, linked beside each fact; where the UK page is silent, a few come from Hue's other English-language sites and say so. Hue changes its range often, so check the model on your box or order and send it with your request. Last checked 1 November 2026.

How the Lily Outdoor Spotlights is powered and mounted

Hue's low-volt system keeps the mains at the socket. The outdoor power supply plugs in there, its 0.6 m lead joins Hue's outdoor cable, and the spotlights branch off that cable through screw-together T-connectors and extensions, each light on a spike in a bed or on a bracket on a wall or fence. Lights and cable are low voltage, yet fixed garden lighting is still an electrical installation within Part P: not notifiable, but expected to be safe, which is why the runs and joints are planned rather than improvised.

Power and cable length set the limits. Hue says a 40 W supply runs five 8 W Lily or three 15 W Lily XL, so a bigger garden, or a mix of both, moves to the 100 W supply and its two outputs. Each low-volt light also repeats the Zigbee signal to the next, so the lights nearest the house carry control out to the far end of the lawn, and Hue's US guidance is to keep each light within about 15 m of another Hue light or the Bridge.

The socket is where many London gardens come unstuck. Hue's instruction is to plug the supply into an outdoor socket, and customer reviews on Hue's UK product pages say its 13 A plug is too bulky for standard weatherproof outdoor sockets. The usual answers are an outdoor socket with a deep in-use lid, or a weatherproof enclosure around the plug and supply. Hue does not describe putting the supply indoors with its cable through the wall, so JACK sticks to Hue's outdoor-socket instruction.

What the pro checks first

Whether you have an outdoor socket, what kind of lid it has, and whether its circuit is RCD-protected
The total wattage of the lights you have bought against the power supply in your kit
Each cable route from the socket to the lights, measured against Hue's length limits
How far the garden is from your Hue Bridge or the nearest Hue light indoors
What each light fixes to: soil for a spike, or brick, a fence post or decking for a bracket
Where paving, a path or decking crosses the route, so the cable can go through conduit

What the pro does on the Lily Outdoor Spotlights

Lights set out on the ground with you before any spike goes in, each aimed at the tree, wall or path it is meant to light
Cable run along borders and fence lines where spades and mowers will not catch it, and through conduit under paving; Hue's UK pages give no burial guidance, so this is JACK practice
T-connectors screwed together firmly, with spare cable coiled out of sight
Power supply plugged in under an in-use lid or inside a weatherproof enclosure, never on an extension lead trailed through a window
Lights added to your Bridge nearest first, so each one repeats the signal to the next
Scenes and schedules, such as dusk until late evening, set with you in the Hue app

How the Lily Outdoor Spotlights installation goes

1Your garden sketch, photos of the socket and the planned light positions reviewed, with the supply size and cable lengths checked
2Socket arrangement confirmed: the existing outdoor socket, an in-use lid, an enclosure, or a new socket priced in
3Lights set out, the cable laid and joined at T-connectors, and spikes and brackets fixed
4Power supply connected and plugged in
5Lights added to the Hue Bridge and tested at the far end of the garden
6Aim, brightness and schedules adjusted with you

Before you book: what to send

A rough plan or photos of the garden marked with where each light should go
What you have bought: base kit, extra lights, extensions, T-connectors and the power supply size
A photo of the outdoor socket and its lid, or a note that there is none
Where your Hue Bridge sits indoors, and roughly how far that is from the garden
Whether any light goes on a wall or fence you share with a neighbour

Is low-voltage garden lighting electrical work?

Yes, though not the kind that has to be notified. How the rules apply in England:

Approved Document P covers fixed lighting in gardens, including extra-low voltage installations powered from the house
Fixed low-volt lighting needs no building control notice unless it involves a new circuit, so a competent pro may install it
Plugging the power supply into an existing outdoor socket makes no change to your fixed wiring
A new outdoor socket taken from an existing circuit is not notifiable either, and it must have 30 mA RCD protection
A brand-new circuit from the consumer unit to the garden is notifiable; that needs a registered electrician, and JACK does not book it

Where the pro adds or alters a socket, ask your pro for a Minor Electrical Installation Works Certificate for that circuit.

Hue low-volt or mains outdoor lights: what each needs

How many Lily spotlights can each Hue power supply run?

Hue's own figures for its two outdoor power supplies, and what they mean for the lights you can hang off each.

Power supply	Power	Cable	Lights, by Hue's numbers
40 W	Up to 40 W; IP67, Class II	35 m of cable at most	Five Lily (8 W) or three Lily XL (15 W)
100 W	Up to 100 W; IP67, Class II	Two outputs, each up to 30 m	Any mix of Lily and Lily XL that stays within 100 W

Hue's extension cable page gives 35 m as the total system length per power supply, which is shorter than the 100 W page suggests, so the pro plans to the lower figure where they differ. JACK does not sell Lily kits or power supplies: you buy them, and the pro installs them.

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.

Frequently asked questions

Do Philips Hue Lily lights need a Hue Bridge?

Yes. The Lily FAQ on Hue's UK page says all outdoor Philips Hue products require a Hue Bridge, sold separately. Each Lily also passes the Zigbee signal on to the next, so the pro adds them nearest the house first and checks the far end of the garden still responds.

Can the Hue outdoor power supply go indoors?

Not by Hue's instructions, which say to plug it into an outdoor socket; Hue does not describe running its low-volt cable through a wall from inside. JACK follows Hue's instruction: if you have no outdoor socket, a pro can add one on an existing circuit with RCD protection, priced before you book.

Does Hue low-volt cable need to be buried?

Hue does not require it: its UK pages give no burial guidance, and its US page says low-voltage cable need not be buried deep or put in metal conduit. JACK's practice is to route it along borders and fences away from spades and mowers, and through conduit wherever it crosses paving.

How much does Philips Hue Lily Outdoor Spotlights installation cost in London?

It is a fixed price for your Lily Outdoor Spotlights, worked out by a vetted pro from the model, a photo of where it is going and what power is there now, and shown in the JACK app before you book. Other devices can go on the same booking for one price. If you would rather pay for time, hourly hire for smart home is typically £45–£95 per hour as a guide.
