  • What is an HID lamp and what cost can I expect?
    ​​​​HID stands for High Intensity Discharge. This type of lamp produces more light and uses less energy than a standard bulb. The quality of light emitted by HIDs is closer to that of natural daylight. Our systems are incredibly energy efficient, our bright green light drawing just 2 amps. You can generally expect energy costs of under $6 per month to operate this system.
  • How long will the HID Lamp last?
    ​Our "Bright Series" bulbs are rated to last approximately 5 years of nightly use. Our "Brilliant Series" bulbs are rated for approximately 2 years of nightly use.
  • What do you mean by "maintenance free bulb"?"
    The heat produced by the bulb each night actually burns off any barnacles. It is for this reason that we recommend that the system be allowed to run every night and not be turned off or added to a timer. Our units feature an exposed bulb, to maximize this heat cleaning effect, unlike a covered bulb system which will require regular cleaning and removing of growth.
  • Isn't LED the newer and better technology?
    LED is great for temporary underwater lighting, such as with our fishing lights and our underwater boat lights, but has flaws as a permanent underwater dock light. The downfall of LED lighting is the fact that it doesn't produce the heat required to burn off the growth mentioned above. In a short period of time you will have to remove the LED light from the water and clean off the growth. In a saltwater application it is even worse for LED. In a matter of weeks the bulb will start to be covered by barnacles and will need to be scraped clean.
  • Why don't we sell lamp cable lengths shorter than 50'?
    Other companies try to lower their prices by offering 30' or 40' length lamp cables. If you think about it you will use the first 10 feet of the cable just from the box to the sea floor, that only leaves you 15 or 20 feet of cable remaining to place your light. Trust us, you would rather have an extra 5 or 10 feet of cable than be short and not be able to place your light where you want. Also, if you feel may need a lamp cord longer than 50', please call or email us we can make a custom longer lamp cord for you (up to 125')
  • Do green underwater lights function?
    Green underwater lights attract fish the most. Underwater fishing lights are typically available in three colors: green, blue, and white. Green is the most popular color since it is the most effective.
  • Why are your power cables only 5' in length?
    We have found that most of our customers mount their control box with-in a few feet of the power outlet on the dock piling, and 5' seems to be the perfect length. We have found that having to long a cable (say a 9') that the gfci plug ends up in the water if the dock light is unplugged and that just causes more problems and headaches for the customer (the plug will have to be replaced). However, if you feel you need a power cable longer than 5', please call or email us and we can make a custom length power cable for you.
  • ​So many choices, which light kit should I choose?"
    Let us clear up some of the confusion you may have. Nearly all of the pictures seen on our website were taken with our basic "bright green" 7,900 lumen single and double lamp kits. These kits are our biggest sellers and the most popular with nothing but satisfying results. If you are looking to simply illuminate your waterway and attract fish, the bright light series of underwater dock lights is all you will really need. Our new style light kits are more for a specific customer. There are some customers that want a brighter light or greener light. Some just want the brightest light available, so we made these additional light kits to satisfy those customers.
  • What do I do if my HID bulb is broken or it burns out?
    If you break a bulb or it burns out we offer replacement bulbs sealed in our coated housing with 50' length marine grade cable for ours and many types of HID underwater dock light systems. If you purchased a green glow dock light kit from us, we offer a 25% discount for our returning customers needing a replacement bulb. (Returning customers please contact us prior to ordering replacement bulbs to receive your discount)
  • How is your HID system "completely automatic"?​"
    Our system has a built in automatic photocell which will turn the unit on at dusk and turn it off again at dawn.
  • What do I need to install your HID dock light kit?
    No wiring of any kind is required by you. Our Lights are a "Plug and Play" System. We provide easy installation instructions. All that is required is that you have a covered 110 volt GFCI outlet and somewhere to mount our box close to it (see pictures). You just simply mount the box with two supplied stainless screws, place the bulb and supplied weight in the water and plug the unit in. It's just that easy.
  • What do you mean by "covered outlet"?"
    You will need to have a "while in use weatherproof outlet cover". This will protect both the light kit's GFI plug and your GFI outlet from moisture (rain). These covers are very easy to install. We have one for purchase that will fit our plugs. Not having a cover may cause problems for underwater light kit owners, it only takes a little amount of moisture to cause a GFI plug and/or outlet to fault and fail.
  • What is the weight for and how do I install?
    The Lamp unit is designed to float, this keeps it off the bottom and out of the sediment. The weight attaches to the lamp cord by supplied zip ties which holds the lamp in place below the surface (the lamp floats above the weight). The weight can be adjusted on the cord by sliding it up or down. We recommend that the lamp be at a minimum of 3' to 4' below the lowest tide to keep it out of boat propellers and trolling motors.
  • Will the 12volt LED Fishing Light work as a dock light?
    The 12volt LED fishing light is intended to be used as a temporary portable light , such as on a boat or fishing pier. While this light is bright enough to function as a dock light, the LED does not produce the heat that our HID dock lights and therefore will not be self-cleaning.
