Why choose LED Aquarium Lighting?

LED Aquarium Light

So why should you choose LED Aquarium / Plant Lighting? Read on...

Advancements in nanotechnologies has led to more powerful, and efficient LED (Light Emitting Diodes) Aquarium Lighting, making them well suited for sustaining aquatic life. It has allowed development of
led aquarium light fixtures, which are capable of producing a highly effective PUR:PAR ratio, thus allowing reef aquarium hobbyists to keep and aqua-culture captive photosynthetic reef invertebrates, including SPS corals.

Metal Halide lighting versus LED

We've personally used metal halide aquarium lighting for many years in the past, before the advancement of LED aquarium lighting, therefore we can tell you first hand that metal halide aquarium lighting lacks in many areas, when compared to modern LED lighting.

Metal Halide Operation: Metal halides contain a mixture of gasses within the bulb. As the device operates, the internal temperature and pressure begins to increase. Unlike metal halides, LED lights do not feature a gas, operating under extreme pressures, at very high temperatures. Instead, the LED lights contain a solid state lighting element, eliminating several risk factors associated with high pressure gases. Solid state lighting has advanced dramatically over the past several years, and has become the industry standard for home saltwater coral lighting applications.

Lighting Start-Up and Cool-Down: During initial start-up, the metal halide will fail to operate at the maximum luminous output. The pressure and temperature within the interior arc chamber may require up to five minutes to achieve the necessary state for optimal performance. During this warm-up period, the metal halide may exhibit numerous colors as a result of vaporization occurring within the arc chamber. In the event of a brief power failure, the arc will extinguish. A cooling period as long as 12 minutes may be required prior to restart. Unlike the metal halide, LED lights respond instantly, and do not require a warm-up period. In the event of a momentary power failure, the LEDs will resume normal operation the moment that power is restored.

Metal Halide and LED Life Span: A single metal halide lamp life expectancy for aquarium use is estimated at 8,000 hours, according to the manufacturer's data sheets, which means the lamps will need to be changed-out every year. Also improper bulb orientation can actually reduce the life by 5,000 hours. Near the end of life, the bulb will begin to exhibit "cycling". As the lamp ages, the required voltage increases beyond the available source voltage. With increasing internal temperature, the lamp will fail. After a brief cooling period, the lamp will re-start. This process will then repeat on a continuing basis. Aging LED lights do not exhibit similar behavior! An LED aquarium light fixture designed to replace metal halides, can provide up to, or in excess of 75,000 hours of life. The LED lights may remain operational for as long as 100,000 hours or more.

LED Lighting Heat Dissipation: LED lights generate significantly less heat when compared to the metal halide bulb. Not only do the LEDs generate less heat, but they also dissipate their thermal energy back into the mounting fixture. Most traditional light bulbs tend to dissipate heat from the front of the bulb, and out into the surrounding atmosphere. This can make thermal management a challenge in certain applications where the direction of heat dissipation becomes critical. Typically aquarium hobbyists using metal halide fixtures will have to run a chiller unit to keep their aquarium at the necessary temperature of 72 to 76 degrees Fahrenheit. Typically aquarium hobbyists running all led aquarium lighting do not have to run a chiller unit at all.

LED Beam Angle: Due to the directional characteristics of traditional metal halides, the bulb produces mass amounts of wasted light from the top and sides of the lens. Not only does this result in a lower system efficiency, but also contributes to environmental "light pollution" in the home. However, LED lights feature superior directional characteristics, and can dramatically reduce pollution. The narrow beam angle of the optic lens featured on LED lights provides illumination within the intended areas only. Not only does this reduce light pollution, but also promotes higher overall system efficiency.

In Conclusion

We hope the above helps you in your decision making, when considering converting to
LED Aquarium Lighting. One last major factor to consider, your LED Aquarium Lighting will eventually pay for itself, from the energy savings on your electric bill.
