Twilight bedtime bulbs are the most optimal lighting to use before bed and during the night

Featuring our relaxing red-light spectrum, that is guaranteed to be 100% blue AND green light free, produce zero flicker, and low EMF.

Blue light and sleep don’t mix

The Twilight Red Light Bulb is the ideal dim lighting to use before bedtime in reading lamps, bedrooms, bathrooms, or anywhere you spend your evening hours prior to going to bed.

Protecting your eyes from blue and green light is not enough. When your skin is exposed to blue and green light at night, it will disrupt your sleep and circadian rhythms.

The BlockBlueLight Twilight Bulb is 100% blue and green light free, has zero flicker, and is low EMF.

Using our proprietary spectrum technology we can deliver flicker free LED light that has no sleep distrusting blue or green light ensuring optional deep and restful sleep.

The twilight bulb is the ideal light source to be used before bedtime when you're ready to wind down and prepare your body for sleep. It specifically simulates the colours you see in a deep orange to red sunset, this triggers your brain to start preparing for sleep.

It’s not just blue. It’s also green.

The BlockBlueLight Twilight Bulb has been specially designed to remove 100% of blue AND 100% of green light. Research shows green light also has an impact on our melatonin production and overall sleep quality. To ensure your lighting environment is not affecting your sleep, you need to block not only all the blue light but all the green light as well.

Whats the difference between the Twilight Bedtime Bulb and the SweetDreams Bulb?

We developed the SweetDreams Bulb to be a more general purpose bulb for use throughout the home to replace most 40w and 60w bulbs. These provide sufficient brightness and colour, all while removing 100% of the harmful blue light. Swapping out most of the bulbs in your house with the SweetDreams Bulbs is a great way to give off a nice, warm, relaxing amber light throughout your home and still fully protect yourself and your loved ones against harmful blue light.

The Twilight Red Light Bulb is a dimmer light with not only all the blue light removed but also all the green light removed. These are great to use in reading lamps, bedrooms and bathrooms, and anywhere you wind down in the evening in the last few hours before bed. They still provide plenty of light to read and see and give off a sunset-deep orange to red glow. They are the ultimate bulb for ensuring the best possible sleep! If you are serious about your sleep, these are the bulbs for you!

Features

BETTER SLEEP: Use the Twilight Bulb before bedtime to wind down and relax. It produces the perfect amount of light to before bedtime without impacting your sleep.

100% of blue AND green light is blocked:This allows your body to naturally wind down at night and secrete maximum melatonin (the sleep hormone) to ensure a deep and restful sleep.

Helps to naturally regulate your circadian rhythm: Twilight Bedtime Bulbs's unique technology allows your body to prepare for sleep, and supports your natural sleep-wake cycle.

STOP HEADACHES & EYESTRAIN:The Twilight Bulb has been created with a constant light source that eliminates all flicker and harsh blue light, providing protection against headaches and eye strain.

Customised spectrum supports a deep, restful and natural sleep: This minimises the blue light energy known to cause sleep disruption.

FLICKER-FREE:Conventional LED lights produce flicker, which is quick fluctuations in brightness that occur many times per second. "Flicker" in an LED bulb is normally not visible to the human eye due to its rapid speed. Flicker has both physiological and neurological effects on our bodies, such as eye strain, fatigue, headaches, and difficulty concentrating. All BlockBlueLight lights have been designed to be flicker-free.

Standard E27 (screw) or B22 (bayonet) base: screw-in or bayonet type fitting - fits most household lamps and overhead light fittings

                      The sheet is too short for my liking
                      Color: Heather Grey(flat Sheet Only), Size: King
                      This king sized top sheet wasn’t quite long enough for a good tuck-in. Can’t comment on wearability because I won’t be using it. Did not return because I had washed it

                      I wanted a sheet that felt warm in the cold weather. Upon reviewing several other sheets, I took a chance on this type. I’m happy I did, no more cold feet in bed! It washes and dries (on low temp.) very well too.

                      So I’ve purchased these twice
                      I purchased these sheets twice because I like them that much. I’m really particular about the texture and material of the sheets I use. After trying jersey sheets about 5-6 years ago, I refused to go back to microfiber. They have the feel of a t-shirt, but it’s your bedding. I love the feeling for my pillowcases, too. This brand’s sheets fit my mattress perfectly. My mattress is a queen sized Casper mattress and 11 inches thick. I’m also a restless sleeper. If the sheets don’t have deep enough pockets, the corners become loose and the fitted sheet tries to escape the mattress. These stay perfectly in place no matter how much I move. As a general note, though, since I see this a lot—PLEASE check the thickness of your mattress! Not all sheets have the same pocket depth! If your mattress is 8 inches thick and you’re buying sheets that are for 6 inches of thickness, it’s not going to fit right! If your mattress is 8 inches thick and you’re purchasing sheets that are for 11+ inches of thickness, they’re more than likely going to be too big, but more likely to stay in place if you buy too small. Still, loose sheets tend to bunch on the actual sleep surface and create uncomfortable fabric ridges. Don’t do that to yourself. Buy the right sized sheets for your mattress! For me, these are perfect! I love the colors available. I tend to buy lighter grays and teals for my bed. They survive my restless sleeping and yucky, sticky humidity of northeastern coast summers. The color doesn’t bleed out when washed. They’re such a soft, comfy texture. The other thing about jersey knit sheets is that the top sheet drapes over your body with a bit more weight. Microfiber is lighter and doesn’t give you the ‘completely covered’ feeling that I find I love about the jersey knit sheets. The jersey knit sheets, I find, because of the material weight, naturally sit and slightly conform to the form they are draped upon. Once again, being a restless sleeper, I do not have to worry that my tossing and turning will cause the sheet to attempt escape from my bed and body on its own. But they also do not make me feel additional warmth. I do not like being hot when I sleep. They are perfectly cool on their own or with a light knit blanket on top. They won’t trap in heat that you don’t want them to. If you want to trap heat, add a warmer blanket. They do tend to be a little on the expensive side in comparison to other jersey knit sheets, so I tend to wait for the sales to grab them! But I really, really like this brand.

                      Size: Queen, Color: Blue
                      Great sheets. They are soft, wash up well, fit as stated. The fabric makes it easier to make the bed. I would recommend to everyone.
