Buying Guide for the Best Solar Tube Skylight
Choosing a solar tube skylight is a fantastic way to bring natural sunlight into rooms that may not have access to exterior walls or traditional windows. Unlike standard skylights, solar tubes are smaller, easier to install, and funnel sunlight down through a highly reflective tube, lighting up even deep or dark areas of your home. When selecting a solar tube skylight, consider your room’s size, ceiling type, and where you want the light to shine. Think about the roof structure, as well as your goals: Do you want a gentle light accent, or are you aiming to brighten up a large space? Keep your own home's layout and lighting needs at the front of your mind as you look at different options.Tube DiameterThe tube diameter determines how much sunlight will be brought into the room. Smaller tubes (around 10-14 inches) are ideal for hallways, bathrooms, closets, or small spaces, offering a subtle glow that lights up smaller areas without being overpowering. Larger tubes (16-21 inches or more) are suited for kitchens, living rooms, or bigger spaces where you want more daylight. Consider how bright you want the room to be; if you're lighting a large area or a room with few other light sources, a bigger diameter tube will be more effective.
Tube Length and FlexibilityTube length refers to the distance from your roof to your ceiling. Shorter distances (for single-story homes or installations directly under the roof) are easier and more efficient, while longer runs (multi-story homes, or when obstacles require routing around structures) will need higher quality, highly reflective tubes to minimize light loss. Flexible tubes can be bent around obstacles but might reflect less light than rigid tubes, which give brighter results but need a more direct path. Think about your roof-to-ceiling path to decide which type suits your space best.
Diffuser TypeThe diffuser is what sits on your ceiling and spreads the light around the room. Some diffusers are frosted for a soft, even light that reduces glare and hot spots, while others are clear for maximum brightness. There are also decorative diffusers that mimic traditional light fittings. Choose the diffuser type based on your lighting preference: If you want gentle, dispersed light in a bedroom or bathroom, opt for frosted; if you need lots of bright light in a kitchen or workspace, a clear version might be better.
Roof Flashing CompatibilityFlashing is part of the skylight system that keeps it watertight where it passes through your roof. Solar tube kits come with different flashings meant for various roof types like shingle, tile, or metal. Make sure that the flashing type matches your roof’s material to avoid water leaks or installation headaches. Take a close look at your roof’s surface and pitch to ensure you’re choosing the right flashing for your installation.
Light Control AccessoriesSome solar tube skylights offer accessories such as light dimmers, night lights, or insulating shades. Dimmers allow you to control the amount of daylight entering your room; this can be handy in bedrooms, nurseries, or media rooms where light levels need to be adjusted. Night lights offer subtle after-dark illumination, while insulating shades help control temperature in extreme weather. Think about when and how you use the room to decide if any of these extra features would add comfort or convenience.
