More info
DC12V 18W submersible LED pool light designed to replace halogen spotlights. With an IP68 protection rating, it is suitable for continuous operation in full immersion. The friction-welded optical lens is developed for underwater lighting, distributing light evenly around the pool while helping control glare for swimmers. The housing is made from high-durability 316 stainless steel with IP68 sealing, offering improved resistance to corrosion. Its robust design also helps reduce breakage risks typical of surface-mounted luminaires made from plastic when exposed to impacts underwater.
Materials and Construction
The fixture combines corrosion-resistant 316 stainless steel with a high-quality PMMA optical lens, ensuring durability against harsh pool chemicals and underwater conditions. The friction-welded lens integrates seamlessly with the housing to prevent water ingress and withstand mechanical impacts.
The solid build reduces the risk of damage common in underwater luminaires constructed from plastic, making it suitable for pools subject to frequent use or maintenance activities.
Optical Performance
Equipped with 12 SMD LEDs rated at 1.5W each, the luminaire achieves an estimated 2340 lumens output with a high efficacy of 130 lm/W. The 120° beam angle enables broad, even illumination of pool surfaces.
The lens design also contributes to glare reduction, enhancing swimmer comfort by minimizing harsh light reflections and hotspots under the water surface.
Color Temperature Options
Two purchasing variants provide distinct white light tones: neutral white at 4000K and cool white at 6000K, allowing customers to choose lighting that best fits the pool ambiance and visual preference.
Both color temperatures maintain a CRI above 80, ensuring colors appear natural and vibrant within illuminated areas.

PAR LED lamps for focused and professional lighting
PAR LED lamps are designed to produce a defined and concentrated beam of light. They provide an efficient alternative to traditional halogen PAR lamps and are used in shops, window displays, restaurants, hotels, galleries, showrooms, homes and other spaces where a particular area needs to be illuminated or highlighted.
At DomiLED you will find PAR LED bulbs in different sizes, power ratings, luminous outputs, beam angles and colour temperatures. Their integrated reflector directs the light forwards, providing more controlled illumination than a conventional bulb with wide light distribution.
Differences between PAR20, PAR30 and PAR38
- PAR20: a compact format suitable for small spotlights, display windows, cabinets and accent lighting.
- PAR30: provides a larger illuminated area and is commonly used in shops, restaurants, galleries and ceiling luminaires.
- PAR38: has a larger diameter and can produce a more powerful beam for high ceilings, larger spaces and certain outdoor applications.
The PAR number indicates the approximate lamp diameter in eighths of an inch. Before ordering, check the dimensions, cap type and available space inside the luminaire.
Beam angle and light output
The beam angle determines how the light is distributed. A narrow beam concentrates illumination on products, artwork, architectural features or decorative objects. A wider beam covers a larger surface and provides more uniform lighting.
Compare the number of lumens to determine the total light output. For accent lighting, luminous intensity measured in candelas can also be useful because it indicates how strongly the light is concentrated in the centre of the beam.
Colour temperature and outdoor use
Warm white creates a comfortable atmosphere in homes, restaurants and hotels. Neutral white displays colours clearly in shops and exhibition areas, while cool white provides brighter illumination for work and functional spaces.
For outdoor use, make sure both the PAR bulb and the luminaire have a suitable IP protection rating against water and dust. If the installation uses a brightness controller, choose a dimmable PAR LED lamp and verify that the dimmer is compatible with LED technology.
Explore our selection of PAR20, PAR30 and PAR38 LED lamps and find the correct power, beam angle and light colour for focused, efficient and durable lighting.
