LED Spa Lighting
A spa light is a lamp, a lens, a gasket and a length of cable. Three of those four are consumables, and the fourth is the reason the other three are replaced.
Fitting, voltage and connector.
Matched on fitting, voltage and connector — in that order.
LED lamp
12 V lamp for the common fitting sizes, in white or RGB, with the lens and gasket that seal it.
Lens and gasket
Replacement lens and O-ring for the fitting, where the lamp is sound and the seal is not.
Harness and extension
Cable with the connector the fitting uses, in the length the cabinet run needs.
Transformer
12 V supply sized to the lamp load, with the enclosure the installation requires.
Fitting and retaining parts
Fitting, retaining ring and the fixings that hold the lamp square in the shell.
Reference data
Mounting, lens and connector.
Mounting arrangements vary by model and may include threaded wall fittings or dedicated niches. Please confirm the lamp, fitting and cable configuration before selection. A lamp that fits but is not sealed is a warranty return with water behind the lens.
| Field | Typical options and what we confirm |
|---|---|
| Mounting | Mounting type confirmed per model: niche-mounted, nicheless or a threaded shell fitting. Seat depth confirmed per enquiry. |
| Supply voltage | Typical: 12 V AC/DC. Transformer confirmed per enquiry. |
| Wattage | Typical: 6 / 12 / 18 W. |
| Colour | Options: RGB, RGBW, 2800–6500 K white. |
| Connector | Photograph the plug at the end of the harness so the mating half is matched from the picture. |
| Cable length | Measure the run from the fitting to the control box and send the figure. |
| Lens and gasket | Read the lens diameter and the O-ring section off the old fitting. |
| Reference system | Why it helps |
|---|---|
| Lamp label | Voltage, wattage and connector as printed |
| Fitting measurement | Diameter across the opening |
| Spa brand and model | Narrows the lighting family and its control |
| Connector photo | The plug that must mate with the harness |
| Transformer label | Available 12 V supply and load |
Lamp compatibility is confirmed per enquiry on the fitting and the connector; output figures are quoted as declared by the maker. Brand names are used for cross-reference only.
What to read on the old light.
Two photos and a voltage answer most lighting enquiries. The replacement bulb or lamp, and what it plugs into.
- Photo of the lamp in the fitting, with a rule across the opening
- Close photo of the connector at the end of the cable
- Transformer label showing the 12 V output
- Whether the colour is white or RGB, and what switches it
- Cable length needed from fitting to control box
- Whether water has entered the lens
Water behind the lens.
A lamp that fogs is a gasket that has aged, not a lamp that has failed. The lens and gasket are quoted with every lamp for that reason.
Seal supplied with the lamp
Lens and O-ring in the box, not as a separate line.
Transformer sized, not guessed
Load is added up across the lamps on the circuit.
Low voltage only
12 V lamps and their supply; no mains-voltage lighting is offered.

Questions about LED spa lights.
Can I replace the lamp without draining the spa?
Only where the fitting allows it. Most fittings are sealed to the shell and are serviced with the water down.
Why does the lens fog?
The gasket has aged or the cable gland is loose. Both are replaceable.
White or RGB?
RGB needs a control that drives the colours; white needs only a 12 V supply.
Do you supply the transformer?
Yes, sized to the lamps on the circuit.
How do I identify the connector?
A close photograph of the plug; connectors differ between lighting families.
Are these lamps certified?
Low-voltage lamps are supplied with the approval route the destination market requires, arranged per order.
Service parts that arrive with a lighting order.
Lighting is usually a small line on a larger order.
