Customizable LED Lighting for 36–42 Inch Aquariums
The Gamalta 36W aquarium LED light combines an automated 24-hour lighting cycle with adjustable colours, brightness settings and expandable mounting brackets. It is designed for aquariums measuring approximately 36–42 inches wide.
Its slim black housing provides broad illumination without adding excessive bulk above the aquarium. Use the automatic natural-light sequence for convenient daily operation or create a custom schedule that suits your aquarium and preferred viewing times.
Automatic Sunrise, Daylight and Moonlight Sequence
The 24/7 lighting mode changes the aquarium’s appearance throughout the day. It progresses through sunrise-inspired light, brighter daytime illumination and lower moonlight-style lighting before switching off.
This gradual visual transition provides a softer alternative to abruptly changing between full brightness and darkness.
Custom Lighting Mode
Custom mode allows the user to adjust key lighting settings, including:
- Operating times
- Colour selection
- Brightness level
- Daytime illumination
- Evening ambience
Choose settings according to the species in your aquarium, room conditions and desired display. Lighting requirements vary between fish, live plants and other aquatic organisms.
Seven Colour Options
The multi-colour LED arrangement can emphasize different elements within the aquarium. White light supports clear general viewing, while red, blue and other colour combinations can enhance the appearance of fish, plants and decorations.
Adjustable Brightness
Brightness can be reduced for evening viewing or increased when stronger display lighting is preferred. Begin with a moderate setting and observe the aquarium before making further adjustments.
Excessive light duration or intensity may contribute to unwanted algae growth, so the most visually intense setting may not be appropriate for every aquarium.
Expandable Brackets for Flexible Installation
The adjustable mounting brackets extend to fit compatible tanks between approximately 36 and 42 inches wide. Position the light centrally above the aquarium to provide more even coverage.
Before installation, confirm that the aquarium edges can support the brackets and that the light remains stable without contacting the water.
Slim Aluminum Housing
The rectangular aluminum body gives the light a clean, modern profile. Aluminum construction also helps disperse heat produced during operation.
Designed for Indoor Aquarium Use
This product is intended for use above indoor fish tanks. Although the lighting unit may provide water-resistant protection against incidental splashes, the adapter, plug, controller and electrical connections must remain dry.

Installation and Setup
Positioning the Light
Extend the brackets until they rest securely on both sides of the aquarium. Centre the fixture and confirm that it cannot slide or fall before connecting it to power.
Electrical Safety
Create a drip loop in the power cable below the electrical outlet. This helps prevent water travelling along the cable toward the plug or outlet.
Keep the following components away from water:
- Power adapter
- Electrical plug
- Controller
- Cable connections
- Wall outlet
Choosing a Lighting Schedule
Lighting needs depend on tank depth, plant species, fish behaviour, surrounding daylight and nutrient levels. Start with a consistent schedule and make gradual changes while observing fish, plants and algae development.
Freshwater and Planted Aquariums
For planted aquariums, select the lighting period according to the needs of the specific plants being kept. This light does not guarantee plant growth and may not meet the requirements of every demanding aquatic plant.
Fish-Only Aquariums
Use a moderate brightness level that allows clear viewing without leaving the tank brightly illuminated throughout the night. Fish should receive a regular period of darkness.
Cleaning and Care
Disconnect the light from power and allow it to cool before cleaning. Wipe the housing with a soft, slightly damp cloth and dry it completely before reconnecting.
Do not immerse the fixture, adapter, controller, plug or cable connections. Avoid abrasive cleaners, chemical sprays and harsh cleaning tools.
Important Safety Information
This is an electrical product intended for indoor aquarium use. Do not submerge any part unless the manufacturer specifically identifies that component as submersible.
Unplug the light before aquarium maintenance. Do not operate it with damaged cables, loose connections or a wet adapter. Install it away from condensation, splashing and areas where it could fall into the aquarium.
Use a GFCI-protected outlet where available. The aquarium light is decorative and functional equipment; it is not a substitute for appropriate aquarium care, professional lighting calculations or species-specific guidance.
