12v AC Waterproof Transformer (Various Wattages) – Versa Plug & Play Output Cable
From: £19.00
This 12v plug & play transformer is for use with 12v Garden Lights, particularly the Versa Plug & Play Range. A 3 pin UK plug is attached to 1m of 3 core rubber waterproof input cable resulting in easy installation with no wiring. The 240v ACÂ mains input then converts to 12v AC output via the transformer. Lumena transformers are available with a choice of 2 core plug and play output cable in various lengths. The output cable is detachable and connects to the transformer and fittings with a 2 pin plug at each end, secured with a threaded cap.
IMPORTANT INFORMATION
The output of this transformer is A/C, therefore may not be suitable for some 12v LED systems. All Lumena 12v LED lamps and fittings will work with this transformer.
DO NOT TOTALLY SUBMERGE IN WATER. Although rated IP68, if the input mains voltage cable should become damaged, a rick of electrocution could result
UK Plug should be located indoors or connected to a waterproof socket.
240v – 12v AC VERSA Plug & Play Transformer
This 12v plug & play transformer is for use with 12v Garden Lights, particularly the Versa Plug & Play Range. A 3 pin UK plug is attached to 1m of 3 core rubber waterproof input cable resulting in easy installation with no wiring. The 240v AC mains input then converts to 12v AC output via the transformer. Lumena 12v transformers / drivers are available with a choice of 2 core plug and play output cable in various lengths. The output cable is detachable and connects to the transformer and fittings with a 2 pin plug at each end, secured with a threaded cap.
Lumena 240v-12v transformers are compatible with dimmable LED bulbs. Whilst the transformers themselves don’t have an adjustable switch or dial, the driver units are compatible with some remote lighting systems, such as Light Symphony.
IMPORTANT INFORMATION
The output of the transformers is A/C, therefore may not be suitable for some 12v LED systems. All Lumena 12v LED lamps and fittings will work with this transformer. The total wattage of a transformer should NEVER exceed the transformer’s wattage. We highly recommend not loading more than 90% of the transformer’s capacity, e.g. up to 45W on a 50W transformer. Lumena 12V transformers perform better over longer periods of time when loaded between 66% and 85% of their capacity.
DO NOT TOTALLY SUBMERGE IN WATER. Although rated IP68, if the input mains voltage cable should become damaged, a risk of electrocution could result.
UK Plug should be located indoors or connected to a waterproof socket.

Garden Lighting Made Easy!
Lumena offer a large range of high end 12v Plug and Play lighting and accessories making it very simple and easy for quick DIY installation. Low voltage lighting is particularly suited to outdoor environments because it tolerates the damp conditions without performance being affected. Anything required underwater should also be low voltage as it is much safer.
When it comes to connections, there are multiple cables and adaptors which are suitable for various 12v plug and play lighting systems. Lumena’s Versa plug & play system is compatible with a number of brands such as Techmar. Cables are available in various length in various combinations of plug & play and open end. In addition, 3 way and 6 way connectors make it very simple for connecting components and fittings to just one transformer.
12v lightings requires a transformer in order for these to be powered. A transformer converts 240v mains down to 12v low voltage. We stock various wattage transformers (10w, 20w, 50w and 100w). Calculate which size transformer is required for a circuit following this simple formula:
Lamp Wattage x Lamp Quantity = Total Wattage Required (minimum)
Example: 5W MR16 x 3 fittings = 15WÂ Â (20W transformer required)
You must never exceed the wattage of a transformer, and avoid underloading. The ideal capacity is 75-90% load.
12v Lighting Set-up Example
12v lighting circuits can use a combination of plug and play and hard wired components. Versa Plug & play is simple with various compatible adaptors, cables and transformers available. Easily convert plug and play to hard wired with our plug & play to open ended cable. Standard junction boxes and in-line connectors can then be used to connect the two systems together.
What is voltage drop?
The term ‘Voltage Drop’ relates to the amount of voltage loss that occurs through all or part of a circuit. This is a result of increased resistance which is a measure of the opposition to current flow in a circuit, measured in ohms (Ω). Electrical cables of any size and length carrying current always present resistance. Although it can affect the entire circuit, it is first apparent at the end of a cable run. A simple comparison would be a garden hose, where the pressure of water running through it reduces the further away it is from its source.
What causes voltage drop?
The 4 main factors which contribute to voltage drop are cable length, wire temperature, wire material and the cross sectional area. Generally, 12V lighting systems can withstand a maximum voltage drop of up to 8% (1V) with no noticeable effects, on the basis that the correct cable / power source is used and it is within range of the LED lamp voltage. If significant voltage drop does occur, it can cause dim lighting, strobing or no power at all.
How to reduce voltage drop
To reduce the risk of voltage drop, consider the following:
- Reduce cable runs – keep length to a minimum with no more than 12 fittings per circuit
- Highly conductive wire, e.g. copper. A tinned end can improve performance and longevity
- Use high quality, heat resistant rubber cable. Minimum H05RN-F
- Use thicker cable where possible (1.5mm² / 2.5mm²) with a secure, watertight connection
For a larger garden where this is not possible, consider laying a mains power feed to various points / areas where additional 12V transformers can be installed to create separate, smaller circuits. 240V fittings can also be connected to the mains feed if required.
Voltage drop cable run guides
Suggested maximum cable run includes cable supplied with each fitting, adaptors and connector cables. Where longer cable runs are required, use thicker cable such as 1.5mm² / 2.5mm² which have a lower resistance and reduce voltage drop. Cable runs can be increased by up to 50% (approx.) when thicker cable is used.
For longer cable runs, thicker cable is recommended. The below table is for 1.5mm and 2.5mm 2 core cable.
The above tables are a guide only. We strongly recommend that the voltage is checked with a volt meter at each fitting prior to final placement. Some external factors can affect performance, such as placement of cable etc.
