LED lightbulbs for aquarium lighting

A few weeks ago we decided to use LED lighting on the new tank racks we had instead of using tubular fluorescent lighting. We used Unitech LED lightbulbs as they were pretty cheap and the cover was made out of plastic and is easily removed. Just a quick twist and it pops off easily. No need to damage the lightbulb and if you want to, you can just plop the cover back in.


With cover




Without cover

Installed it to the middle rack in parallel connection with all the lights connected to one switch. Flipped on the switch and all the LED lightbulb burst to life. Been observing the lightbulbs for some time and so far the performance is good.

Used to have 12-24watts of lighting per 15gallon tank but now with these energy efficient LED, its down to 3-5watts per tank. By removing the cover of the bulb it greatly reduces the glare and gives a kind of spotlight effect making it unnecessary to install hoods or reflectors.

The manufacturer claims that the light produced by one watt is equivalent to 8watts of standard CFL (compact fluorescent light) bulbs and by rough comparison it seems to hold true.



With a 30,000 hour lifespan (if true as claimed), these LED light bulbs are worth every cent so if you're setting up a new tank or need to change a busted tank light you should give it a try. The only problem is if you don't have enough room for a receptacle above your tank. This is true for most fish racks but otherwise, they are a great alternative.



UPDATE (July 01, 2015)




The 3 watts LED bulbs wasn't quite enough for aquatic plants with high light requirements so we decided to up the game a little with a higher wattage LED bulb. We switched one of the 3 watts LED bulb (which was still in good working condition) to a higher wattage LED bulb. 







This is an LED from another brand, Isonic, since the previously used LED bulbs (Unitech) were out of stock. We used the 9watts cool light variety and unlike the Unitech LED bulb's cover which was fairly easy to remove, this one required a little bit of hacking. After prying the cover of the bulb open with a small knife, the LED module needed to be glued back on to the housing which required a brisk walk to the nearby motorcycle accessories store to purchase a small tube of fast bonding adhesive (I used Superglue).

The LED bulb cover makes a great hideout for cichlids. They love it very much.

The brightness is obviously higher than then 3 watts LED bulb (left side on cichlid tank) since it is 9 watts and it uniformly illuminates the 15 gallons tank (right side filled with freshly harvested aquatic plants) pretty well.

MP | Cardinal Tetra Profile

From Wikimedia Commons, the free media repository Species Name: Cardinal Tetra ( Paracheirodon axelrodi )   Description: Cardinal Tetras are small, vibrant freshwater fish native to the Amazon Basin in South America. They are part of the Characidae family and are closely related to the more commonly known Neon Tetras. Cardinal Tetras are named for their striking colors. Their bodies are primarily bright blue, extending from the tip of the nose to the base of the tail, with a prominent horizontal red stripe running from the middle of the body to the base of the tail. The combination of electric blue and vivid red makes them one of the most popular choices among aquarium enthusiasts.     Habitat: Cardinal Tetras are found in slow-moving waters, including tributaries, small rivers, and streams within the Amazon rain forest. They prefer areas with dense vegetation and subdued lighting, mimicking their natural habitat in the wild.     Behavior: These tetras are known for their schooling be

Why is regular water change important?

Should we be wasting our time doing regular water change? Is it really that important? The real question here is why shouldn't we? Doing regular water changes is the basic way for ensuring that the environment our aquatic pets live in is not only aesthetically pleasing to our eyes but most important of all, is fit for the general well-being of our aquatic pets and their surroundings. Some beginners in the aquatic pet hobby think that the only reason why we need to do water change is for water clarity. A clear water as a matter of fact doesn’t mean that your tank water is clean. It is just the same as a drinking water. Being clear doesn’t mean that it is fit for drinking. It could contain harmful chemical which are not visible to the naked eye but are unhealthy for you. Filtration systems especially those high-end expensive types can help keep the tank environment in optimal condition but this doesn't mean that we no longer need to do water changes in our tank.
