Blue Light Blocking Light Bulbs and Lighting

BlockBlueLight’s LED bulbs have been engineered to offer a comfortable and low-stimulation lighting environment, suitable for use in the evening hours. These bulbs have been designed to minimize exposure to blue light, feature flicker-reduction technology, and operate with low electromagnetic output.

Our Sweet Dreams amber bulbs are crafted to reduce blue light exposure below 500nm, while our Twilight red light Bulbs go even further by reducing both blue and green light up to 570nm.

Unlike many standard LED bulbs that may emit higher levels of blue light and exhibit flickering characteristics, BlockBlueLight’s bulbs are purpose-built for nighttime use, offering a softer, more relaxing light that’s easier on the eyes in the evening hours. 

While conventional LED bulbs are known for emitting high levels of blue light and often exhibit flickering, BlockBlueLight’s lighting solutions are engineered differently.

Most standard LED bulbs produce a sharp peak in the blue light spectrum and lack the warmer amber and red wavelengths commonly found in natural light. This unbalanced light profile can contribute to visual discomfort and may be stimulating when used in the evening.

BlockBlueLight’s lighting range has been carefully developed to reduce blue light exposure, eliminate perceptible flicker, and emit a warmer, more consistent glow. Our products do not emit wavelengths in the blue spectrum and are designed to support a more comfortable lighting environment at night.

All lighting products are also low EMF and use advanced driver technology for a smoother visual experience.

Not all coloured bulbs are created equal. While some red or orange light bulbs may appear to produce low-blue light, their internal light sources may still emit measurable amounts of blue wavelengths.

At BlockBlueLight, we test all our lighting products using spectrometer analysis to ensure they emit only the intended spectrum and are free from blue light emissions (and green light for our red-light range).

Many budget bulbs use coloured filters rather than engineered light spectra, which may not effectively minimise unwanted wavelengths. Additionally, lower-cost bulbs often exhibit flickering and may not be optimised for evening or night-time use.

All our products are carefully designed to support more balanced evening lighting by reducing high-intensity wavelengths, operating without perceptible flicker, and keeping EMF levels low. We make our spectral reports available to provide full transparency on the light output of each bulb.

The SweetDreams Bulb was designed as a versatile, general-purpose lighting solution to replace most 60-watt bulbs throughout the home. It provides a soft amber glow that supports a relaxing evening environment while minimising exposure to high-intensity blue wavelengths.

The Twilight Bedtime Red Bulb is a dimmer option, engineered to reduce both blue and green light. Its deeper red hue creates a calm ambiance—ideal for bedrooms, reading areas, and spaces where winding down before bed is a priority. These bulbs still provide practical brightness while promoting a more restful nighttime atmosphere.

Using a combination of both amber and red low-blue lighting throughout the home can be an effective way to create lighting conditions that align better with natural evening rhythms. Amber bulbs are ideal for overhead lighting and general use, while red bulbs are better suited for late-night use in bedrooms, children's rooms, or other relaxation zones.

Yes absolutely, we have designed these bulbs to be a general use light bulb for all areas of the home, they provide sufficient light for living areas and bedrooms, but also give off a warm, relaxing, soft light making them suitable for reading lamps and nurseries.

Because eliminating blue light at night is so important, you should use the SweetDreams bulbs in any room you or your family typically spend evening and night hours.

Ideally, you would turn off your lights and keep your room as dark as possible during sleep. However, if you are uncomfortable sleeping with the lights off, we recommend using our Red Night Lights which have been designed to provide very low wattage and just enough dim light to take the darkness out of the room, and these can safely be kept on while sleeping.

Our light bulbs are not suitable to be used with dimmer switches or to be dimmed. This is by design, because when LED bulbs are dimmed and are not running at full brightness it significantly increases the amount of flicker from the light, it also creates high EMF levels being emitted from the bulbs. We have designed our light bulbs to be flicker free and low EMF, so to not compromise this we have made them non dimmable.

We do have our flicker free NoBlue Amber Lamp, Twilight Red Light Lamp, and the NoBlue Book Light, which have 3 brightness settings which make a suitable light source to use if you would like to raise and lower the brightness of the light.
