Twilight Red Light Bulb (Screw & Bayonet)

Base Fitting:

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!

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.
