Fluorescent Aquarium Lights

Fluorescent aquarium lights are a popular choice for plant and older fish hobbyists. They provide an inexpensive way to light up the tank and provide beneficial lighting for aquatic plants and animals. 

Various types of fluorescent lighting are available, each with pros and cons.

Benefits of Fluorescent Lights:

Fluorescent lights offer a variety of benefits when compared to other types of aquarium lighting. 

Fluorescent lamps emit less heat than metal halides, making them an excellent choice for tanks that may not be able to handle the heat.

Additionally, fluorescent bulbs last longer than other bulbs, meaning you won’t have to replace them as often. 

Finally, they can be found in a wide range of colors and intensities so you can suit your tank’s needs.

Types of Fluorescent Lights:

There are two main types of fluorescent aquarium lights available;

  • T5 Tubes
  • T8 Tubes

The difference between these two is primarily size.

Size always matters!

T5 tubes are thinner than their T8 counterparts, but both will fit into standard hoods designed for fluorescent bulbs. 

A range of lengths, extending from 12 to 48 inches, are available for both T5 and T8 tubes.

Pros and Cons of Fluorescent Lights:

On the one hand, they produce less heat, making them great for smaller tanks, but on the other hand, they don’t put out as much light intensity as alternatives like LEDs or metal halides.

If you want intense illumination, this may not be your best option. 

Additionally, installation can sometimes be tricky because they require special ballasts (which are only occasionally included).

Cost Considerations For Fluorescent Lights:

When it comes down to cost, fluorescents typically run cheaper than LED.

However, the overall cost can quickly increase since most setups require multiple fixtures. 

Plenty of options are available if you are looking for budget-friendly solutions;

  • Current USA Orbit Marine Pro LED+T5 Combo Fixture. This light offers both LED and T5 bulb capabilities at an affordable price. 
  • The Aqueon Modular LED+T8 fixture provides dual, LED-only modes and combination modes, allowing users greater flexibility when setting up their tanks.
Key Takeaway: The key takeaway from this article is that fluorescent lights are a great budget-friendly option for aquariums, offering both long-lasting bulbs and customizable lighting without breaking the bank.

Halogen Aquarium Lights

Halogen aquarium lights are ideal for amplifying illumination and adding a splash of color.

Halogen bulbs provide bright, white light that can bring out the vibrant colors of your fish and plants. 

Halogen bulbs boast an extended lifespan, making them a cost-effective selection in the grand scheme.

Benefits of Halogen Lights:

Halogen aquarium lights offer several benefits compared to other types of lighting. 

The most obvious benefit is their intense brightness, which can make even dull-colored fish appear more vivid and vibrant. 

Additionally, halogens have a much longer lifespan than fluorescent, up to 10 times as long. 

Finally, halogens emit less heat than other forms of lighting, so they won’t raise the temperature inside your tank too much when used correctly.

Types of Halogen Lights:

Two main types of halogen aquarium lights are available on the market today.

  • Incandescent
  • Quartz-halide lamps (also known as metal-halide). 
  • Incandescent bulbs are generally cheaper but produce less light intensity.

Quartz-halide lamps are more expensive but generate brighter illumination with better color rendering capabilities.

Halogen aquarium lights provide intense brightness and a longer lifespan than other types of lighting. 

These bulbs get crazy hot, so keep them far away from anything that can catch fire.


Generally, halogen lights are more expensive upfront than LED/fluorescent options.

However, they may save money in the long run due to their extended lifespan and fewer replacements required throughout their lifetime. 

If budget constraints prevent purchasing high-end models, then consider opting for lower-priced alternatives such as;

  • The TMC AquaRay GroBeam 600 Ultima. 
  • Zoo Med PowerSun UV Metal Halide. 

Both come equipped with built-in safety features to ensure safe use while providing ample illumination to grow aquatic plants and corals.

Key Takeaway: Halogen aquarium lights provide intense brightness and a longer lifespan than other types of lighting. However, they require higher wattage, which may increase electricity bills.

Metal Halide Aquarium Lights

Metal Halide aquarium lights are one of the most potent lighting options for aquarists. 

If you need to call Batman, use a Metal Halide!

They produce a bright, white light ideal for replicating natural sunlight and providing intense illumination to your tank. 

Metal halide lighting has been a staple of commercial aquariums for decades, yet its popularity among hobbyists is steadily increasing.

Benefits of Metal Halide Lights:

Metal halide lights are known for their intense brightness and long life span. 

This makes them ideal for larger tanks that require more light than other types of lighting can provide. 

Finally, metal halides emit whole spectrum light, which helps promote healthy growth in plants while providing natural-looking colors on your fish’s scales and fins.

Types Of Metal Halide

Metal Halide lights come in various types, each with its advantages and disadvantages. 

  • SEs, are comparatively economical but with less longevity.
  • DEs, are the most commonly seen bulbs. 
  • Compact fluorescent lamps (CFLs) offer excellent energy efficiency but may need to be more brightly for some tanks. 
  • High-intensity discharge lamps (HIDs) provide the highest output levels yet generate more heat than other options. 
  • LED chipsets offer excellent color rendering capabilities without generating much heat.

The main upside of metal halides is their high luminosity and extended life compared to other light sources, such as fluorescent lamps or LEDs. However, these same features can also be seen as disadvantages since they require more electricity. 

Additionally, they generate quite a bit more heat, so you must choose an appropriate size fixture based on your tank size/dimensions to avoid overheating issues.

Cost Considerations For Metal Halide Lights:

When it comes down to cost considerations, metal halides will generally cost you significantly more upfront.

Primarily, they contain rare earth elements like mercury vapor inside each bulb. 

On top of this, you will need additional components such as ballasts, reflectors, and timers which add even further costs to the overall setup price tag. 

This all sounds like lots of work to me.

Key Takeaway: Metal halide lights provide intense brightness and a long lifespan but come with higher upfront costs. Still, if cost is not a concern, their extended life and dazzling brilliance make them an investment worth considering due to the reduced upkeep costs over time.
