Ultra-Thin Pool Lights: A Detailed Guide

Ultra-Thin Pool Lights

Ultra-thin pool lights are popular with many people for their unique shape. This article details the Slimline pool lights to help you understand this type of product.

What Are Ultra-Thin Pool Lights?

Ultra-thin pool lights are not a new type of pool light, they are still normal pool lights. The most obvious difference between them and other pool lights is the thinner body of the light. There are currently no clear regulations in the pool lighting industry regarding the thickness of ultra-thin pool lights.

How Do You Make ‘Ultra-Thin’ Pool Lights?

The answer is to make the luminaire body thinner. Below are some common design options.


The interior of an ultra-thin pool light is very compact, simplifying heat dissipation and some electronic components.


Some ultra-thin pool lights have a thinner housing than conventional pool lights.


The lens allows the angle of the LED chip to be adjusted, thus changing the beam angle of the LED pool light. Many ultra-thin pool lights do not have a lens to save space.


LED pool lights have face caps that transmit light and seal the light body to prevent water from entering the light body. Some of these covers also have an anti-glare design to soften the light.

The cover itself has a certain thickness. Some pool light cover even protrude outwards, which increases the thickness of the pool light considerably. The ultra-thin pool light has a flat face cover and a significantly reduced overall thickness.

The Advantages of Ultra-Thin Pool Lights

Ultra-thin pool light is also a kind of LED pool light. The advantages of LED pool light such as energy saving, environmental protection, high brightness, safety, and rich lighting effect also exist in ultra-thin pool light. In addition, the ultra-thin pool light also has some characteristics.

Lighter and thinner

The old pool lights, whether made of metal, plastic or toughened glass, were large and heavy, but the advent of LEDs has made them lighter, and the ultra-thin pool light is certainly better at this.

A better fit to the pool wall

The ultra-thin pool light is even more advantageous when used in an surface mounted installation. This is because there is very little protrusion when installed and it does not take up significantly more space in the pool. The ultra-thin pool light looks even better when installed.

Some pools cannot be fitted with a recessed pool light due to the type of pool, wall thickness etc. By choosing an ultra-thin pool light, the use of a surface mounted installation can approach the effect of a recessed installation.

A better and safer experience

Even with suface mounting, the slimline pool light fits more snugly against the pool wall. In the event of an accident, there is less chance of personal injury or equipment damage due to impact.

Disadvantages of Ultra-Thin Pool Lights

The advantages of ultra-thin pool lights are outstanding, and the disadvantages are also very obvious.

Difficult to achieve high power

The increased power of LED pool lights is accompanied by thicker electronic components and increased heat generation. Most ultra-thin pools have compact interiors with weaker thermal design and heat dissipation than ordinary pool lights. As a result, ultra-thin pool lights are rarely available in high wattages.

For normal pools only

High temperature applications such as spas require a higher level of heat dissipation from LED pool lights. High temperature resistant pool lights have thicker internal aluminium substrates and more thermal conductors to help dissipate the heat from the pool light. The small internal space of an ultra-thin pool light obviously does not support this.

Inability to fit a lens

Lenses adjust the beam angle of the pool light. Most LED pool lights with adjustable beam angle have a lens fitted in the position of LED chips.

There are two types of LED chips : SMD and COB.

SMD chips are smaller and only have a 120° beam angle choice.

Pool light with SMD chips

COB chips are larger and are suitable for adding lenses to achieve more beam angles.

Pool light with COB chips

Most ultra-thin pool lights use SMD chips to save internal space and only have a 120° beam angle. Slightly less durable products without face caps.

Some ultra-thin pool lights omit the face cover construction and rely on filled resin for waterproofing and light transmission. These pool lights can be thinner and lighter, but are not as durable as regular pool lights.

When Is a Ultra-Thin Pool Light the Right Choice?

When you choose surface mounted pool lights, you should consider choosing ultra-thinline pool lights in the following situations :

  • Domestic pool
  • More beautiful
  • Want easy installation and maintenance

Some recessed pool lights have equally very thin bodies. You can also opt for ultra-thin recessed pool lights.

Features of WAKING’s Ultra-Thin Pool Lights

WAKING Lighting uses stainless steel for the body material of all its ultra-thin pool lights. This material has a good texture, is durable and conducts heat better than plastic. Some of WAKING Lighting’s ultra-thin pool lights are available in a standardised design with a choice of surface or recessed mounting options.


Ultra-thin pool lights have many compelling advantages as a new pool lighting option. However, we can’t ignore some of their disadvantages either. We hope that the detailed description of slim pool lights in this article can help you make a better choice.
