Food, water, sleep—three things every person would name as human necessities. However, sleep is one we compromise way too often, and now is the time to stop. Are you tired of restless nights and unnecessary early mornings because of annoying light? Desperate for the best blackout shades that effectively block the sun? We have the answers with Hunter Douglas’ latest innovation: LightLock™.
What Makes the Best Blackout Shades?
Not every dark fabric creates a true blackout experience. A shade can block light through the fabric itself, but small amounts of light may still sneak in around the edges of the window. These are called light gaps, and while they block the majority of light, they can make a big difference in bedrooms, nurseries and media rooms.

The best blackout shades combine opaque fabrics with a custom fit and light-blocking details that reduce side gaps. That’s what creates the darkest possible environment for sleep, movie watching or any room where light control really matters.

If you’re still comparing your options, start with our guide to room darkening vs blackout shades. Room darkening shades reduce light, while blackout shades are designed to create the darkest possible environment.
LightLock™ Unveiled

Offered with Duette® Honeycomb Shades, LightLock™ is one of Hunter Douglas’ most impressive blackout innovations. This system is designed to block light from entering through the shade fabric and along the sides of the window, creating a room that feels calm, dark and ready for rest.
Why Duette® Shades with LightLock™ Are Considered the Best Blackout Shades
One of the biggest challenges with blackout window treatments is preventing light from entering around the edges of the shade. Hunter Douglas addressed this issue with LightLock™, a system designed specifically for Duette® Honeycomb Shades. LightLock™ uses specially engineered side channels that help block light from entering along the sides of the window. The result is an exceptionally dark environment that is ideal for bedrooms, nurseries and media rooms.

Designer Roller Shades can also be customized with blackout side channels, offering another solution for homeowners who prefer a clean, contemporary look. Your designer can help determine which blackout system best fits your windows, style and light control goals.
Which Blackout Shades Are Best?
The best blackout shades depend on how dark you want the room, how the window is shaped and how much flexibility you need throughout the day.
| Shade Type | Blackout Potential | Best For |
|---|---|---|
| Duette® Honeycomb Shades with LightLock™ | Excellent | Bedrooms, nurseries and media rooms that need maximum darkness |
| Designer Roller Shades with Blackout Side Channels | Excellent | Modern spaces that need strong blackout performance with a clean roller shade look |
| Roman Shades with Room Darkening Fabric | Very Good | Bedrooms where softness, style and privacy matter |
| Woven Wood Shades with Blackout Liner | Good | Natural texture with added light control |
| Dual Shades | Flexible | Rooms that need light filtering by day and room darkening at night |
Best Blackout Shades for Bedrooms
Many homeowners searching for blackout shades for bedrooms are looking for a solution that blocks early morning sunlight, streetlights and distracting outdoor light. Master bedrooms, guest rooms and children’s rooms can all benefit from a darker, more restful environment.

If the setting sun makes bedtime feel too early—or morning light wakes everyone before they’re ready—the right bedroom blackout shades can help your family stay on a better sleep schedule. The darkened atmosphere of the room makes it easier to wind down at night and sleep longer in the morning.
Blackout Shades for Nurseries
Nursery blackout shades are especially helpful when nap time happens during bright daylight hours. A darker room can make it easier for little ones to rest, even when the sun is still shining outside. Cordless or motorized options also help create a safer, simpler setup for children’s rooms.

Motorized Blackout Shades for Better Sleep
Getting your family on a solid sleep schedule is easier when your shades can adjust automatically. With motorized blackout shades, you can schedule your window treatments to close at bedtime and open in the morning.

PowerView® Automation allows you to create routines that support the way your household lives. Let the rooms darken themselves in the evening, then bring in morning sunshine when it’s time to start the day.
Best Blackout Shades for Media Rooms & Home Theaters
Blackout shades aren’t just for bedrooms. They’re also a strong choice for media rooms, family rooms and home theaters. When glare gets in the way of movie night or game day, blackout window treatments help create a theater-like environment.

They can also improve comfort in sunrooms, guest rooms and home offices where bright sunlight causes heat, glare or privacy concerns.
Control More Than Light
The best blackout shades do more than darken a room. They can also help create a better atmosphere. Temperature, glare and even sound can all influence how comfortable a room feels.

Energy efficient shades can help maintain temperatures, while darker fabrics and blackout liners can improve comfort in rooms with intense sunlight. If heat is part of the problem, explore our energy efficient window treatments. If bright light is the bigger issue, we can also help you reduce glare with custom window coverings.
Do You Need Blackout or Room Darkening?
If you want the darkest room possible, blackout shades with features like LightLock™ are the best choice. If you simply want to reduce light for comfort, privacy or screen visibility, room darkening may be enough.
