Big Glow by Studio Truly Truly
“We missed the sun,but also desired the gentle, comforting glow of soft light.
We wanted to achieve this with a sustainable focus”
Kate Booy - Studio Truly Truly

The Culture of Light

Remember the warmth of the sun.
It’s not just a feeling, it’s an experience.
It’s like coming home.

Light, in all its forms, welcomes us differently across the globe, shaped by geography and culture.
The Australian sun blazes with intensity, while Northern Europe basks in a gentler, cosier glow.

“Wool perfectly embodies the warm and comforting quality we were searching for. The fibres have a soft ecru colour, and the glow of the material is genuinely natural as a result.”
Joel Booy - Studio Truly Truly

The Wool Revolution

At the heart of Big Glow lies its pioneering use of Australian wool. Inherently luxurious, beautifully soft and enduringly relevant. Through intensive research and development and utilising technical knowledge from Woolmark, Rakumba has harnessed a material that combines non-woven wool with plant-derived compostable fibre formulated as bioplastic. This innovative blend combines a sense of luxury, sound absorption, and beautiful light diffusion.

Sustainability & Traceability

The entire production process of the wool, from wool-growing to final assembly, occurs within Victoria, Australia. This commitment to local production supports Australian industry, provides traceability and reduces the resource footprint of each piece.

The environmental credentials of wool – a natural, renewable, biodegradable and recyclable fibre - combined with natural bioplastic results in a certified compostable material made from renewable resources.

Creating lasting beauty without lasting waste.

Studio Truly Truly is a Netherlands-based design studio founded by Australian husband and wife team Joel & Kate Booy. Studio Truly Truly operates in a variety of creative fields including design of products, lighting, furniture, textiles and spatial installations as well as art-direction.

Studio Truly Truly focus on designing thoughtful products for the living environment that combine function with sensuality, and which result from an urge to question and invigorate the way people use and perceive objects. The studio employs art as an avenue to push the boundaries for themselves and for others. They have a growing interest to investigate future furniture typologies, and in this, question form in relation to function.

FAQs

Will Big Glow biodegrade under everyday conditions?
Toggle FAQ

No. Like all Rakumba lights, Big Glow is built to last. Its unique wool blend panels retain their physical and performance qualities when installed and maintained as recommended. Biodegradation occurs only under specific, controlled composting conditions, much like an article of wool clothing.

Is Big Glow lit from inside by a globe that needs replacing?
Toggle FAQ

No. Instead, Big Glow features permanent dual LED light sources, with one side facing downward and the other side directed internally. Light diffusing through Big Glow’s textile panels creates the impression of an internal light source.

Can the two light sources in Big Glow be controlled separately?
Toggle FAQ

Yes, this is the recommended installation method. The internal ambient glow and the downward task lighting are individually controllable (this requires two drivers and the installing electrician will need two install two switches/dimmers). For simpler installation, both internal and downward lighting can be controlled together using a single driver and dimmer. A non-dimming driver is also available, but we recommend specifying dimming to achieve the full potential of the light.

Is Big Glow suitable for kitchens or bathrooms?
Toggle FAQ

Big Glow’s unique wool blend panels need to be cared for in a similar manner to fabric upholstery and other textile furnishings. Do not use cleaning products on Big Glow’s wool blend panels.

Whilst there’s no specific restriction regarding interior spaces where Big Glow can be installed, avoid installing near heat sources, wet areas, or where moisture, smoke, oil or other cooking residue may settle on the fixture, as this will likely affect its appearance or performance over time.

Can Big Glow be used in humid or coastal environments?
Toggle FAQ

Yes. Big Glow is designed to perform reliably in humid climates, and the components used are corrosion resistant for coastal locations. Big Glow is exclusively for indoor spaces.

Can Big Glow be cleaned?
Toggle FAQ

Use a soft microfibre cloth to clean metal trims. Use a duster, compressed air, or a lint roller to clean the exterior. Do not use cleaning sprays. Big Glow is loosely sealed to reduce insect accumulation, but if insects do find their way inside, periodically remove the diffuser panel in the top of the pendant and vacuum insects out with long extension.
CRITICAL NOTE: Exercise extreme care - vacuum must be at the minimal setting to prevent damage to the textile panels.

Does Big Glow provide sound-dampening/acoustic benefits?
Toggle FAQ

Yes. The large size, rounded form, and naturally soft textile panels absorb and diffuse sound, enhancing acoustics in both small and large spaces. Acoustic performance test figures will soon be available for professional project consideration.

How is Big Glow sustainable?
Toggle FAQ

Big Glow’s textile panels are crafted from a blend of two renewable, compostable materials: locally sourced wool and a plant-derived bioplastic fibre. Additionally, Big Glow solves one of the biggest negatives of large format lighting, with a flat-pack assembly method that dramatically reduces the shipping volume and thus reduces embodied transport impact.

Big Glow is flat packed for shipping efficiency. Is any assembly required?
Toggle FAQ

Yes, some assembly is needed. To minimise shipping costs and environmental impact, Big Glow is shipped with the panels partially disassembled. For a person with practical skills, assembly typically takes between 60 to 90 minutes to prepare the product for installation. Some dealers may offer pre-assembly services. Please note that after assembly, final installation must always be carried out by a licensed professional electrician in compliance with local regulations.

Can a panel be replaced if it becomes damaged or marked?
Toggle FAQ

The square shaped side panels can be replaced in sets of two (note that this does require the pendant to be taken down and reassembled). The bottom or top ‘domes’ are replaceable as  full subassemblies (the bottom dome is inclusive of the LED lightsource).

Note that replacement panels may vary in colour and texture due to variations in natural wool batching, manufacturing variations, and sun and environmental exposure of Big Glow after installation.

Can moths damage Big Glow?
Toggle FAQ

Big Glow has not undergone any specific moth-proofing treatments. Regular cleaning and inspection is recommended to prevent moth infestation.

Does Big Glow include Dim to Warm technology?
Toggle FAQ

Big Glow is optionally available with Dim to Warm technology. As the light is dimmed, it transitions from a mid-warm colour (3000K) to a soft, amber glow (1800K), creating a cozy and inviting atmosphere.

What is Big Glow’s price range?
Toggle FAQ

Pricing varies across the range. Please contact us or your local dealer for details.
