Lighting has always played more than a decorative role in aquariums. Behind the glass, the right aquarium light isn’t aesthetic; it’s environmental. It shapes plant growth, fish health, and the entire rhythm of the underwater cycle.
In many households, aquariums are often found in living rooms, offices, and even kitchens. Whether built around a planted tank or a reef, each one is a self-contained system that needs structure, not guesswork. That starts with the proper lighting. At Ubuy Philippines, fish tank lights span everything from UV steriliser systems to high-output LED fixtures. These aren’t soft glows for ambience. They regulate photosynthesis, algae growth, and fish circadian rhythms with specific spectrums and cycle settings.
Different aquariums demand different lighting setups. From freshwater to the reef and planted tanks to low-light biotopes, every light source has a specific technical role. Below, we break down the most common types used in home aquariums today.
LED lights have become the default for most home aquariums. They use low power, generate little heat, and offer programmable spectrums. Most aquarium LED strip models are available in white, blue, and full RGB colour options, such as the NICREW ClassicLED or Hygger Programmable Aquarium Lamp LED, which provide 24-hour light cycle simulation, including sunrise, daylight, dusk, and night settings.
These lights last upwards of 50,000 hours and often come with IP67 water resistance, protecting against splash exposure. LED aquarium light units are ideal for tanks between 10 and 120 gallons, with mounting brackets that fit standard glass rim widths. Ubuy Philippines stocks LED fish tank lights suitable for both low-light aquarium plants and high-growth CO₂ setups. To help you out in picking the right branded LED light for your Aquarium. We've pointed out a comment from a user on the post "Best light for a 29 gallon", check it out and bring clarity to your choice:
"I use submersible seaouras in my 29 gallons. They’re surprisingly bright for their wattage but the timer resets whenever there’s a power outage.
You need to hook them up to a separate timer to prevent that."

There are some other popular comments which you can also spot and make a decision. See another LED light choice for you to go forward with:
"I love my Fluval lights. They connect to my phone via Bluetooth and I can adjust spectrums and timelines with the app. I'm able to control the growth of my plants quite easily. They were pricey but worth it."

UV steriliser aquarium systems are not designed to light the tank visually. Instead, they emit ultraviolet radiation that kills algae spores, harmful bacteria, and parasites in the water column. These lights sit inside a closed housing with water passed through the steriliser chamber. The UV bulb typically ranges from 3W to 55W, depending on tank volume.
Brands like Coralife and Aquatop manufacture internal and inline UV filters that integrate with existing aquarium pumps and filters. A UV filter aquarium setup helps maintain water clarity in overstocked or reef tanks where the biological load is higher.
T5 and T8 fluorescent tubes have been standard for decades in freshwater aquariums. While slowly replaced by LED, they remain relevant in specific use cases. T5HO lamps offer a high PAR (Photosynthetically Active Radiation) value, making them ideal for high-tech planted tanks.
Typical sizes include 24”, 36”, and 48” tubes with Kelvin ratings from 6,500K to 10,000K. Brands such as Fluval and BeamsWork produce T5 fixtures with dual and quad-lamp hoods, often with independent on/off switches for photoperiod control. Their heat output requires adequate ventilation and usually complements aquarium heaters and chillers for temperature regulation.
Blue-spectrum lighting isn’t decorative; it penetrates deeper water and supports coral fluorescence. Actinic lights are used heavily in reef tanks, providing wavelengths between 420 and 460 nm. These mimic deep-sea sunlight conditions, bringing out the natural pigmentations in coral, shrimp, and marine fish.
Systems like the Kessil A160WE offer targeted actinic spectrum blending with shimmer effects. When used in combination with full-spectrum white, the blue light for fish tank setups allows both aesthetic and biological accuracy. These lights are often paired with programmable reef controllers and fish food for nutrient-timed light cycles.
Night lighting creates a low-output, non-disruptive glow that allows for nocturnal viewing without affecting fish sleep cycles. Typically using dim blue or red LEDs, these lights are set below 0.5 watts per litre. Models like the Hygger Submersible Night Light or NICREW Moonlight feature auto-on sensors or timer integration.
Unlike standard lighting, night lights remain on after the primary cycle and assist in observing species such as catfish, loaches, or shrimp that are active after dark. These lights can also help reduce stress for fish startled by complete darkness. Most systems clip to the tank rim or adhere via suction.
Not all aquarium lamps grow plants. Aquatic plant lighting requires a spectrum between 6,500K and 7,500K for optimal photosynthesis. Systems like the Finnex Planted+ or Fluval Plant 3.0 offer red, blue, and white light combinations, along with programmable day-night cycles and adjustable intensity.
These lights are essential for tanks featuring plants such as Cryptocoryne, Java Fern, or Amazon Sword, which are classified as low- to medium-light tolerant. High-output LEDs (HO-LEDs) with a PAR value above 70 µmol/m²/s are used in tanks with CO₂ injection or in carpeting plants, such as Hemianthus or Monte Carlo. Fish tank LED light replacement units should always match existing wattage and spectrum requirements.
Marine aquariums demand higher-intensity lighting for coral growth and symbiotic algae health (zooxanthellae). Reef lighting often combines multiple light types: high-PAR LED arrays, actinic blues, and shimmer-focused designs.
Brands like Kessil and Coralife use optical lens technology to avoid hot-spotting. Reef-specific fixtures deliver an output of up to 1000 µmol/m²/s at a depth of 12 inches. These lights are best mounted 6–12 inches above open-top tanks with fan-assisted cooling. Additionally, compatibility with Wi-Fi controllers and ramp timers allows tuning for SPS, LPS, and soft coral variations.
Black lights, which emit a UV-A spectrum ranging from 365 to 400 nm, highlight fluorescent pigments in particular species. Although rarely used as a primary light source, black light is often used in fish tanks to highlight GloFish or other genetically enhanced breeds. These should be used sparingly and only for limited hours, as prolonged exposure can affect natural behaviour and stress levels.
Fixture integration usually occurs through clip-on auxiliary bars or magnetic-mount strips. It's best for show setups, not everyday tanks.
Here's how leading lights available on Ubuy compare across key features and user experiences:

People usually choose LED aquarium lights because of their low heat output and programmable features available on Ubuy Philippines. UV steriliser systems remain a niche yet effective solution for enhancing water clarity. In planted setups, spectrum control and PAR value have a greater influence on growth outcomes than brightness.
