12V vs mains recessed ground lights

Updated: 22 October 2026

You already have a low-voltage cable in the border, or you are looking at a round well and cannot tell whether it wants a transformer. This comparison of 12V vs mains recessed ground lights uses nine amazon.co.uk listings. Five are mains GU10 holders that state no transformer. Four are extra-low voltage wells, and none of those four includes the transformer. The full check order is on the [recessed ground light buying guide](/hub/garden-decor/recessed-ground-light/sub/recessed-ground-light-buying-guide). The rows are on the [recessed ground light comparison](/hub/garden-decor/recessed-ground-light). Peter F. compared those listings.

Two supplies, not one product type

The mains group is ledscom.de at 230 V, EBION at 110–240 V, both YOVGQOLV packs at 220–240 V, and Auraglow at 240 V. They are GU10 holders with no transformer. EBION and Auraglow leave the bulb out. YOVGQOLV states a 5 W 3000 K lamp. The low-voltage group is the CNBRIGHTER mini, the honeycomb well, the 3 W side-slot well, and HIBOITEC. The carton does not contain the supply. After that split, 12 V still divides into DC and AC.

DC, AC, and the words on the bullet

The mini, model TMDM-1W-Mini, says 12 V DC and not 12 V AC. Lumena's note on a 12 V waterproof transformer says the output is AC and may not suit some 12 V LED systems, so this £15.99 marker is outside that bullet. It is about 87 lumen, a marker rather than a mains uplight. The honeycomb well states 12–24 V DC and compatible with 12 V AC. The side-slot well states 12–24 V DC and also AC/DC, so those rows do not agree. HIBOITEC's bullet is 12–24 V AC/DC. Match the words on the listing you buy.

What the box does not contain

None of the four low-voltage listings includes the transformer. The side-slot well names one as an extra. HIBOITEC leaves the transformer and the wire out and includes six screw-lock connectors. A UK review calls the mini's lead short. Mains holders say no transformer because they expect 230 V-class wiring. Auraglow's 1 m flex is still mains. Extra-low voltage at the well does not delete Part P on the transformer primary. Burial and the stop points sit on how to install recessed ground lights.

Brightness is not the same job

The mini is about 87 lumen and the honeycomb about 95, both 1 W. The side-slot well is 195 lumen and throws light sideways. An empty GU10 holder has no lumen figure until you fit a lamp, so do not compare 87 lumen with EBION's 11,200 lumen attribute. A 1 W well will not imitate a mains uplight. The best recessed ground lights page splits those jobs without crowning one star line.

Common questions

Which captured lights are 230 V and which are extra-low voltage?
ledscom.de, EBION, both YOVGQOLV packs, and Auraglow are the mains GU10 holders, from 110–240 V on EBION up to a stated 240 V on Auraglow. The three CNBRIGHTER wells and HIBOITEC are the extra-low voltage group. The mains bullets say no transformer. The low-voltage bullets require a supply the box does not include. A round stainless cover appears on both sides, so the photo is not the test. The voltage line is.
Can you put the mini CNBRIGHTER on a 12 V AC garden transformer?
No. The bullet says 12 V DC and states that it is not 12 V AC. A plug-in garden transformer that outputs AC can be the wrong half of 12 V, which is the warning Lumena prints on its own AC transformer. Use a DC supply that matches the bullet, or choose a different fitting whose words allow AC. Sharing the number 12 is not compatibility.
Does compatible with 12 V AC mean the same as 12 V DC only?
No. The honeycomb well at £21.99 uses the wider sentence: 12–24 V DC and compatible with 12 V AC. The mini uses the narrow one and rejects AC. The side-slot bullet says 12–24 V DC while another line says AC/DC, so that row is unresolved. HIBOITEC says 12–24 V AC/DC in the bullet. Read the sentence on the listing you are buying. Do not average them into one 12 V rule.
Is the transformer in the HIBOITEC or CNBRIGHTER box?
No. HIBOITEC states that the transformer and the wire are not included. The CNBRIGHTER side-slot lists a transformer as an optional extra. The mini and the honeycomb do not include one either. Six screw-lock connectors on HIBOITEC are not a transformer. Budget for a supply that matches the AC or DC words, and keep that transformer out of a wet zone rather than in the same flooded pocket as the well.
Why do mains GU10 packs say no transformer?
Because they are 220–240 V or 240 V fittings, not because the transformer was forgotten. Auraglow, EBION, YOVGQOLV, and ledscom.de are holders you connect to a mains circuit. Saying no transformer is a description of the supply, not a claim that installation is trivial. Mains outdoor lighting remains a job for a registered electrician. The flex in the Auraglow box is still a mains flex.
Does a 12 V fitting remove Part P?
No. Fixed garden lighting stays in scope in England and Wales, and the primary side of a transformer is still mains. A 12 V well can be the extra-low voltage end of a circuit that begins at a consumer unit. Notification is a separate, narrower question and belongs with the install page. Do not treat low voltage on a bullet as an exemption from the Building Regulations or from RCD protection on a new or significantly altered luminaire circuit.
