The Prism Light
Turn any wall into a work of art.
Blank walls make a room feel flat. The Prism throws a sweeping beam of colored light that changes the whole mood of a space.
- A conversation piece. A small crystal lens casts a sweeping beam of light across your wall.
- Three moods. Warm white, golden sunset or a dreamy blue-purple.
- Tiny footprint. Just 7.5 cm long, so it fits on any nightstand, shelf or console.
- Made for evenings. It looks best in a dim room, the perfect backdrop for winding down.

How big is it?
About 7.5 cm long and 5 cm tall (3 × 2 in).
Where should I put it?
Near a wall in a dim room. The closer it is to the wall, the smaller and brighter the beam.

What if I don't like it?

Full details & specs
Paint your wall with light.
The Prism is a small crystal lens on a metal stand. Light passes through the crystal and throws a sweeping beam across your wall, turning an empty corner into something people notice.
Three moods
- Warm white: soft and elegant.
- Sunset: a golden-orange glow.
- Blue purple: a dreamy mix of pink, violet and teal.
Good to know

Our philosophy
Light isn't just for seeing.
Your body reads light as a signal. Bright, cool light tells it to stay alert. Warm, low light tells it the day is winding down. That's why the same desk can feel energizing at 10am and exhausting at 10pm.
Most homes and offices use one harsh overhead light for everything. We built the Halo so you can choose the light that fits the moment.
Cool white
Light for focus
Studies link cooler, blue-enriched light with faster reactions and higher alertness during demanding tasks. Switch to cool white when you need to lock in.
Warm, dimmed
Light for rest
Bright light late in the evening delays melatonin, the hormone that helps you wind down. Switch to warm and dim it low when the work is done.
What the research says
~90 min
Ordinary room light before bedtime pushed back the start of melatonin by about 90 minutes compared with dim light.

Cool, blue-enriched light led to faster reaction times on attention tasks and higher alertness than warmer 2500–3000K light.

In an office study, warm 3000K light at moderate brightness produced the lowest mental workload, showing that the right light depends on the task.

Reading on a light-emitting screen before bed delayed sleep and circadian timing and reduced alertness the next morning.
