Perfect for adding additional light to show off your aquatic plants, corals or amazing fish. Now you can accent the inside of your aquarium without adding clutter to the outside.

  • In-frame mount and integrated cord routing
  • Rotating adjustment dial directs light where needed
  • Fully submersible with suction cups (included) for placement anywhere in the aquarium
  • On/off switch on cord for easy control

I just bought the Marineland 60 gallon ensemble and have replaced the t8 bulbs with floramax bulbs and know I need more lighting for my large plant collection. Is this fixture good for plants or some other hidden led system good for plants?

Asked by: Jofish
The blue and white Hidden LED light would be suitable for live plants, yes. For this size tank, we recommend at least two of them, depending on the types of plants you plan to keep. BREX

Attaching to a 23g bowfront

I have a 23 gallon bowfront tank, 30" W x 12" D (at the middle' 10" at either end) x 18" H Can I either 1) attach the light to the front with the suction cups (presumably it can't clip on due to the curve), or 2) attach it to the straight back. The issue at the back is that it has an attached lid, with the hinges on the back frame. I presume that it being waterproof would mean I can have it under the HOB filter.
Asked by: ScottAR
It would not fit on the front at all, no. You would have to make room for it on the back. It comes in a 17" and a 21". BREX

I bought the 17" hidden light, will this grow plants in my 10 gallon tank? Would it be considered, low, medium or high light output? This will help me with my plant selection, thank you.

Low to moderate light plants would do well with this light. BREX

are these lights dimmable

would like to be able to dim the lights. this would allow me to use a controller to turn them on/off gradually to desired level to simulate typical daytime light and make the fish more comfortable about lights (no turning off and on when the kids want to see them, etc.)

No, they are not. BREX

Can I replace flourescent with LED lighting?

I have your model PFES12 and the lighting fixture seems corroded. Can I change to an LED and if so, which would be appropriate?
Asked by: RLA45
Yes, and no. You cannot place one inside the cover. You would need to cut the cord of the old light, and use a Hidden LED which would snap into the frame at the front of the tank. BREX

Asked by: jdf25
They will definitely fit, but no, they are not programable. I'm not sure if they will be enough for your tank since I don't know what you house in your tank. They are extremely bright, however, and good for live plants. BREX

hidden Led lights

I have both of the hidden led light and both of them have condensation in each tube.. why advertise as water proof when indeed they are not?
Asked by: usarng2000I
Because they are waterproof, however, when they are first plugged in, moisture that was trapped inside, when they were sealed, may cause minor condensation that is not an issue. If they are showing more than minor condensation or it is interfering with their working capability, there may be a bad seal. You have a one year warranty on them. BREX

will a 21 inch one light my 37 gallon tank and will it grow plants

Asked by: asdfgh
It will definitely aid in growing plants, although your tank is pretty tall. The height will reduce this ability somewhat. This is a very bright light, however, and should have no issues lighting the tank. BREX

I have a 6' fish tank, and the top is complicated for lights (not exactly clear). Will this work, and will it grow plants?

Will this light work for plant growthin my 6' fishtank? Would I be better off with 3 21" lights, or 4 17" lights? Or, should I double the amount of light and put some in the front and the back? This is a standard 6' long 125 g tank.
Asked by: EMSY
While our Hidden LED lights are not marketed for their strength to grow or sustain aquatic plant growth, depending on the types of plants and your plants' light needs, you may still be successful. The issue is the depth of your tank and how much light energy is needed to permeate through that depth to reach your plants for photsynthesis needs. While you may need to do some extra research on what amount of light energy your plants require, the specs of this LED's light is below (scroll down and click on the "product manuals and instructions" link for lighting spec information). http://www.marineland.com/Products/aquarium-lighting/LED-Aquarium-Lighting/freshwater-saltwater-reef-aquarium-led-lighting-system.aspx ML2

Marineland Hidden LED Lighting System w/30-gl Saltwater Tank

Are the 460nm blue LEDs enough to support life such as sea anemones and/or plants? Also, I'd like to leave the blue LEDs on all night? Is this ok for the fish, crustaceans, etc?
Asked by: Ranman
This light is meant more as a supplemental light as the white lights in it are not 10,000-14,000 Kelvin. You would need the Reef LED Strip. No, do not leave them on all night as this would not occur in nature, and would be detrimental to the livestock. BREX

I'm trying to get enough light for dwarf baby tears. I currently have a 16 G bow front with a 15 watt light. Will this provide enough extra light?

I need something fully submersible as I have a hang on back filter that would get in the way of hanging another light on the back rim.
Asked by: Snorg
Assuming your 15 watt bulb is a grow light or plant bulb with 6500 Kelvin, yes, this should be enough. One note of concern is that I assume you will mostly have the baby tears in the front of the tank since it is a foreground plant. Since your tank is a bow front, this will not fit on the front. It is submersible, so I am assuming you plan on putting it further down on the back of the tank. This may still be too far away if the plants are in the foreground. BREX

What size tank does this item fit?

I have a 60 gallon tank. Would this item be to small?
Asked by: nicki70
For something like a 60 gallon tank, most people put two of these in the tank. These are 21" long so that would cover 42" of the 48". They are quite bright, by the way, if you are considering them as the sole light for your tank. BREX

hidden led lighting

Are the hidden led lighting lights suitable for coral growth, and if so how many do I need for my 55 gallon led aquarium kit?

Can you hook up more than one, end to end?

I currently have one of these light strips on my 20 gallon tank, but am getting ready to set up my 120 gallon tank which is 6' long. What do you suggest?
Asked by: nicwatts
No, they do not connect like you are hoping. I would recommend the LED strip lights. Which one depends on what you will be housing in the tank, but I would recommend two 48" lights which have legs that extend out to 60 inches. One in front and one in back. BREX

Best way to clean hard water deposits?

Hello, with the hidden LED's being submerged I am wondering the best way to clean them not only for hard water but also for algae that may get behind the light. 1. Can vinegar be used to wipe them down for the hard water? 2. Is it alright to snap the lightbulb out to clean the assembly area? or how do you recommend cleaning around the light itself? Thanks
Asked by: cmclien
Yes in answer to both questions. The light portion can be pulled out so you can clean around it and clean the black frame portion. I would recommend a distilled white vinegar solution with hot water. Probably a 50:50 ratio and use a soft cloth that won't scratch. BREX

Does this work for glo fish?

Wondering if this light has enough blue lights for Glo fish? Can you run the blue lights with the white lights or would we need to add more blue?
Asked by: Adriscoll
You can run the blue and white lights together or just the blue alone. The blue lights are deeply blue, 460 nm. I would suggest trying just this light to see if it is enough blue for the glofish or not. I think it would be, but that depends on the individual tank. If it is not, then supplement with the Accent Light in Blue. BREX

Can we retrofit the LED system onto a Eclipse 24 x 13 lid
