If you are looking for a place to escape from life’s every day hustle and bustle,Look for IP (Ingress Protection) rated fixtures that are waterproof, meaning dust-tight and protected against long immersion in water, rather than simply “water safe” or “wet location safe” options. Waterproof fixtures are meant to be submerged and will prevent water from entering them due to sealed assembly. Take the precaution to ensure that your fixtures will meet all safety and application standards for an underwater environment prior to purchase or installation.
Ingress Protection (IP) ratings specify the environmental protection the enclosure provides.
The IP rating normally has two (or three) numbers:
An “X” can used for one of the digits if there is only one class of protection, i.e. IPX1 which addresses protection against vertically falling drops of water e.g. condensation.
IP First number – Protection against Solid Objects
IP Second number – Protection against Liquids
Voltage Requirements
When weighing your options on which type of fixture to choose, cost, convenience, and the size of your project are important. If one were to complete a large project for the grounds of a grand hotel, for example, line voltage (120V) would be the ideal option as vast distances may exist between the focal point and the fixture itself.
While it’s also true that standard incandescent bulbs can be found at virtually any hardware or household goods store, in an age where environmental awareness is important to daily life, technology and the public are moving in tandem towards different solutions. Since line voltage lighting consumes much more energy and will typically require the expertise of a licensed electrician, more homeowners are choosing low voltage (12V) options. Low voltage fixtures are notably the safer and less hazardous of the two choices, are often smaller, and easier to conceal within a natural landscape. They also have the added benefit of lower cost over time. Note that a transformer is required to convert to the lower voltage for fixtures which will be used underwater. You may also make use of photocells and timers to save on electricity consumption costs even further.
Let’s take a look at some examples of the different types of submersible low voltage products available today:
Low Voltage Halogen
This LED lights consume approximately 75% less power than incandescent units for the same amount of light output. This amounts to a sizeable savings over their life span. Moreover, standard underwater LED fixtures consume about 1/5 of the power as standard incandescent bulbs!
Besides energy savings, the nature of LED production makes them ideal for underwater applications. There are no bulbs to change as LED fixtures typically come in a permanently sealed housing. Sealed construction means underwater lights may be left in a permanent location with no concerns about extra cable allowances, or making provisions to change bulbs. They should, however, be accessible in order to clean the lenses during regular pond maintenance.
