Best Solar Tube

solar tube

Solar tube lighting is a highly innovative means of providing indoor illumination and the wider benefits of the sun’s rays in general anywhere of your choosing within a building. Where it differs from traditional window lighting is that it uses a through-the-roof design. This means that areas once inaccessible to window light can then benefit from daytime illumination without the need for additional electricity.

Today’s aim is to make you aware of the many benefits available with these tube installations and give you a full rundown of how they work as well as weighing up the pros and cons of using them in your home or workplace.

What Are Solar Tubes?

What makes a solar tube so effective as both a light source and a long-term cost-saving complement to your home is the fact that it relies on the sun’s rays to provide light. The top “cap” of these tubes is placed on the exterior of a building and is primed for maximum photon ray absorption before the light is then sent down the central tube for reflection within your interior space.

Enhanced efficiency comes from the interior tube coating, which has been specially designed to efficiently disperse light and provide optimum brightness. This means that a solar light tube is not going to cost you a penny after installation because it is a completely self-sustaining source of illumination thanks to its exclusive reliance on the sun.

There are other benefits besides illumination here too. They come in the form of additional natural heat thanks to the concentration of the sun’s rays and the ability of the body to create vitamin D without being exposed to the sun for prolonged periods of time. All in all, this makes solar tube lighting an incredibly sought after utility option that thousands of homeowners are already enjoying on a daily basis.

Things to Consider Before Buying Solar Tubes

Even though solar tubes will prove highly effective for many, there are still several areas that you need to review before you commit to buying a set. Unlike other sun-powered products, installing this item leads to the permanent alteration of your roof structure. Or that is to say, it is very hard to effectively restore your roof back to its original state should one of these tubes be removed.

As a result, you need to make absolutely sure that it is going to be the right option for you going forward. Comparing the following key areas and determining whether or not they are relevant to your situation will help you to simplify the decision-making process.

A solar tube or a skylight?

Although they may seem similar, there is a significant difference between these two lighting options especially when it comes to cost and installation.

First, solar tubing can be woven into the structure of a roof with fairly minimal interruption to its design. A skylight, on the other hand, is a very large feature that requires a sizeable gap to be created in your roof in order to achieve successful implementation.

Whereas tubing can offer lighting levels that are likely to be more than adequate for the majority of people’s needs, a skylight differs by offering a fairly expansive window that will bring in a higher level of light. More is not always better though, as you might get more illumination than you need.


Solar tube installation cannot be summed up in one set of steps because the process is slightly different depending on the type of building you have. It is all about your roof type and, therefore, the shape and sometimes materials of the product you are going to need.

It probably goes without saying that a flat roof is very different from a slanted roof just as an asphalt roof is significantly different from a shingle roof. As a result, there are a variety of models available to cater to the needs of any and all homeowners.

You are going to have to pay very close attention to the specifications of your desired product. If you can, try to view the related manual online before making a purchase so that you are fully aware of what to expect.


Realistically, it is actually very difficult to damage a sun tunnel (as they are sometimes called) due to its mostly concealed infrastructure. But where this aspect can and rarely does go wrong, is with the exterior cap.

You will have a variety of options at your disposal when it comes to material choices, but the most durable tunnel covers are typically made out of impact-resistant glass. This makes them very resistant to force and weather damage. It is important that you buy the right solar tube to prepare for the risks posed in your specific location.

Although you are not likely to encounter any tampering from other people due to the tubes’ inaccessible location, curious critters are still likely to find their way onto your roof. Your tube caps need to be sturdy enough to withstand everything from clawing to nibbling.

What is the warranty like?

A warranty might not be the first thing on your mind when you are shopping for most solar tube products because of the low price and lack of major real-world disruption possibilities. When you are installing something within the structure of your house though, peace of mind is paramount.

Some models carry up to a 25-year warranty, meaning that, in most cases, you will probably be covered for the entire duration of your stay in one particular home. Alternatively, some have a significantly shorter warranty and may be less durable.

Tube size and brightness

Tube size is typically measured in inches, and you can get a reasonably good idea about how much light is going to be produced based on the wattage capacity of the tube. The range is usually anywhere from 300 watts to as much as 1500 for larger options.

If you are looking to light a bigger area, a bigger tube is required. For a smaller area, it is going to require a smaller tube. Gauge your options based on your exact needs. Once the tubing is in place, removal or replacement would be a very difficult undertaking.


Sometimes, it is best to go with a well-established brand rather than trying to scour the market and review every available option. For those who want to make a fairly quick but still assured decision when purchasing a product within this category, the following manufacturers are known to produce high-calibre items: Velux, Solar Blaster, Radiant, ODL, and Natural Light.

Since this is a niche market, there are not an overwhelming number of manufacturers to choose from. But this is not necessarily a bad thing because those available have been able to focus on being specialists in their area for a considerable amount of time.

For those who want a light that will shine over a large area, this kit offers the perfect solution and an incredibly durable and easy-to-install design.

The 10-inch tube can provide up to 300 watts of brightness, which is going to be more than adequate to meet the needs of those who want to cover a relatively small area. You will need something bigger for a large room, but generally, there is enough illumination here to please most. This is especially true when you consider that this wattage can be projected up to 150 feet.

It is one of the few options that has been hurricane tested and offers an excellent warranty length. You have no reason to be concerned once your initial installation has been completed. This tubing system is very unlikely to be damaged, and if it is, you are covered.

1. 14 in. Sun Tunnel Tubular Skylight Acrylic Dome


14 in. sun tunnel tubular skylight acrylic dome - solar tube

For those who are not totally confident about installation, this model is going to offer some much-needed peace of mind thanks to the flexible ribbed tube design that allows for maximum flexibility and optimum placement. So accessible is this model, in fact, that it only takes 2 hours to install on average.

The cap is made from a flat glass plate, meaning that you are unlikely to encounter any serious external or internal damage. The size of the tube is 14 inches. This gives way to an impressive level of internal light concentration and will meet most people’s visibility requirements.

If you are confident that you know exactly what type of roof you are working with and have minimal obstructions within the roof, you can also opt for a rigid-tube model. However, the level of tube flexibility is slightly diminished with this variant, which may make placement harder.

  • Excellent light output from 14-inch head
  • Durable glass cap with protection from external elements
  • Sufficient 20-year warranty

  • Very, very cost effective and no financial outlay after initial installation
  • Cheaper to buy than windowed light access
  • DIY installation without labour costs
  • Not as disruptive as windows or skylights and much easier to install
  • Not as invasive to your home’s exterior appearance as a skylight
