أضواء الصيد LED تحت الماء: Complete Buyer Guide

Comlite manufactures underwater LED fishing lights from 8W to 5000W for freshwater and saltwater use. Our range covers 12V/24V DC submersible lights for boats, kayaks and portable battery packs, 110V-240V AC lights for docks and fish farms, and high-output deep sea units built for commercial fleets.

This page explains how underwater fishing lights actually attract fish, which LED colour suits which species, and how to specify voltage, wattage and depth rating before you request a quote. If you already know what you need, go straight to our 12V/24V range or deep sea range.

What Is an Underwater LED Fishing Light?

An underwater LED fishing light is a fully submersible luminaire designed to be lowered into the water and left running for hours at a time. Unlike a deck light or a flood light mounted above the waterline, a submersible fishing light creates an illuminated column below the surface. That column is what pulls in plankton, then baitfish, and eventually the predator fish you are targeting.

A typical Comlite unit combines a sealed LED array, a corrosion-resistant housing, a reinforced cable entry and — on higher-power models — a stainless steel protective cage. Because the light never leaves the water during operation, sealing is the single most important design decision in the product. We build to IP68 across the range and pressure-test every deep sea model before shipment. Tell us your working depth and we will send the test conditions together with your quotation.

Submersible vs Surface-Mounted Fishing Lights

Submersible lights go into the water and build the food chain from below. Surface-mounted or onboard lights sit above the waterline and spread light across the surface. They solve different problems.

A submersible light is a fish attractor. An onboard light is a work light that lets you see your deck, your lines and your catch. Serious night operations usually run both — one to bring fish in, one to land them. You can see our above-water range on the Onboard & Dock Fishing Lights page.

How Underwater Fishing Lights Attract Fish

Underwater lights do not attract game fish directly. They start a chain reaction:

Water temperature matters. Below about 10°C (50°F) the entire chain slows significantly, so cold-water and ice fishing sessions need more patience and a longer runtime.

Two practical consequences follow from this. أولاً, light first, fish later — give the light time to work before you start casting. Second, run time beats peak brightness. A moderate light running for six hours will usually out-fish a very bright light running for ninety minutes.

A Note on Running Lights in Air

Submersible fishing lights use the surrounding water as a heat sink. Most will overheat within 30-60 seconds if switched on in open air, which can crack the potting compound or damage the LEDs. Always submerge the light fully before connecting power, and let it cool in the water before you haul it back aboard.

LED Colour Guide: أخضر, أزرق, White and Warm White

LED colour is not a cosmetic choice. Different wavelengths penetrate water differently, and different species respond to different parts of the spectrum.

Colourطول الموجةPenetrates best inBest for
أخضر520-560 نانومترFreshwater, inshore estuariesCrappie, bass, redfish, snook, trout — general purpose
أزرق450-495 نانومترClear offshore saltwaterSquid, mackerel, deep-water snapper
أبيضBroad spectrumMurky water, general visibilityAll-round visibility; more surface glare
أبيض دافئ / أصفر570-590 نانومترShallow water, occupied areasFewer flying insects; softer light for docks and patios

أخضر penetrates freshwater further than any other visible wavelength and matches the bioluminescence that triggers a plankton feeding response. It is the safest all-round choice for freshwater and inshore saltwater.

أزرق travels furthest through clear offshore saltwater and mimics deep-ocean bioluminescence. It is the preferred colour for squid and deep-water species.

أبيض gives the highest perceived brightness and works well in murky water, but it creates more surface glare and can spook shallow, skittish fish.

If you are not sure which colour to specify, our Dual Colour & RGB Fishing Lights let you switch colour on the water instead of committing to one before you know your conditions.

How to Choose: ضغط, Wattage and Depth Rating

Voltage — 12V/24V DC or 110V-240V AC

If the light will run from a battery on a boat, a kayak or a portable pack, you need 12V or 24V DC. Our DC range runs from 8W portable units up to 800W mid-power lights.

If you have shore power, a generator or a fixed installation at a dock, a fish farm or a fish cage, 110V-240V AC lets you run far higher output. Our AC range covers 600W to 5000W.

As a rough sizing rule: a 20W light draws about 1.7A at 12V, while a 120W light draws about 10A. A 100Ah deep-cycle battery will run a 20W light for roughly 48 hours but a 120W light for only about 8 الساعات. Match the light to the battery you already own, not the one you plan to buy.

Wattage

Depth Rating and Ingress Protection

Continuous submersion requires IP68 — not IP65 or IP67. IP65 and IP67 cover water jets, splashes and temporary immersion. They do not cover a light left at depth all night.

Beyond the IP code, ask two questions of any supplier. What depth is the light rated for, and is that a test result or a marketing number? And does the rating hold at temperature, in saltwater, and after repeated pressure cycles? Our deep sea range uses 316L stainless steel housings and is pressure-tested before shipment; we will share the test method and conditions on request. Always specify a rating comfortably above your maximum working depth.

Housing and Cable

Saltwater destroys aluminium and standard steel quickly. For permanent or semi-permanent saltwater use, specify 316L stainless steel or a marine-grade polymer housing, and check that the cable entry is a moulded gland rather than a simple grommet. Cable length is our most common customisation request — tell us the length you need and we will build to it.

Dock and Pier Lighting

A fixed underwater light turns a dock into a reliable night fishing spot. Most dock owners choose a 12V/24V green light in the 20-60W range for seasonal use, or an AC unit where mains power is available. Because the light stays in one place, corrosion resistance and cable quality matter more than raw output.

Boat and Kayak Night Fishing

On a boat with a house battery, a 12V light between 60W and 450W is the usual choice. Kayak and small-boat anglers are better served by a compact 8-20W unit on a small lithium pack, where portability matters more than coverage.

Fish Farm and Aquaculture

Beyond attracting wild fish, underwater lights are used in cages and ponds to concentrate stock for feeding and harvesting, and to support algae growth. Because these lights run for long hours every night, the priority shifts from peak brightness to energy efficiency, thermal management and serviceability. Comlite supplies fish farm and aquaculture lighting for pond, cage and hatchery installations.

Deep Sea and Commercial Fishing

Commercial operators need output, depth rating and repeatability. Our 600W-5000W AC units are built for deep drop work, longline sets and large cages, with dimming available on selected models so crews can manage generator load. Talk to us about fleet pricing.

الأسئلة الشائعة

What colour LED light attracts the most fish?

أخضر (520-560 نانومتر) is the most effective all-round choice. It penetrates freshwater further than other wavelengths and triggers the plankton bloom that starts the food chain. For squid and deep-water species in clear saltwater, أزرق (450-495 نانومتر) usually performs better.

Can I run an underwater fishing light out of the water?

لا. Submersible fishing lights rely on water for cooling and can overheat within 30-60 seconds in open air, which can crack the sealing compound or damage the LEDs. Always submerge the light fully before connecting power.

How long does it take for an underwater light to attract fish?

In healthy freshwater, plankton gathers within 15-30 دقائق, baitfish follow within 30-60 دقائق, and predator species typically arrive within 1-3 الساعات. Saltwater is slower — allow 2-4 الساعات. Water below 10°C (50°F) slows the whole chain.

Do I need 12V or 220V?

If you are running from a boat battery or portable pack, choose 12V or 24V DC. If you have mains power at a dock, fish farm or fixed installation, choose 110V-240V AC — it supports much higher output.

How deep should I submerge the light?

It depends on water clarity. Around 1-3 metres works in clear water; in murky or tannic water, keep the light shallower so the beam can spread. Always choose a light with a depth rating well above the depth you actually fish.

Do you support OEM and private labelling?

نعم. We provide OEM and ODM services including custom LED colours, wattage, cable length, housing material, logo printing and retail packaging. Minimum order quantity and lead time depend on wattage, housing material and customisation — send us your specification and we will quote firm numbers.
