Chroma Sky Portal 2.1 desk light

Chroma Sky Portal 2.1: desk light that follows the day

Most indoor lighting is either too harsh or too dim for how our eyes and body clocks work. The Sky Portal 2.1 is Chroma’s desk‑scale answer: zero‑flicker daytime white when you need focus, then deep amber with 660 nm red when you want evening calm.

"I keep these on my desk and they’ve completely changed how I feel through the day - more focused, more energised, and way less sluggish. I love how they support my circadian rhythm while I work, especially when I can’t get outside as much." - Darren

Why we love it

💗 Day mode that feels like proper light. Circadian‑aligned white for work blocks, per Chroma [1].

💗 Night mode with amber + 660 nm red. A gentler evening spectrum on the same device [1].

💗 Flicker‑free, per Chroma. Built for long hours at a desk without the buzz of cheap LEDs [1].

💗 Darren’s daily driver. Keeps it on the desk for focus when outdoor time is short.

What the research says

Daytime bright light supports alertness; evening light that’s rich in blue can push sleep later. Reviews on melanopic light and circadian timing explain why spectrum and schedule both matter [2].

Chroma’s framing — zero‑flicker, circadian‑aligned white by day, deep amber with 660 nm red by night — is Chroma’s product design claim [1]. It’s the reason Darren leaves his on the desk instead of relying on overhead office LEDs alone.

How to use it

🌿 Daytime white during morning and deep‑work blocks [1]

🌿 Switch to deep amber / 660 nm red in the evening [1]

🌿 Place it in your peripheral view at a comfortable height

🌿 Pair with outdoor daylight when you can — this supports the hours you can’t get outside

Who it’s perfect for

✅ Desk‑based work with too little natural light

✅ You want one device for day focus and evening wind‑down

✅ You like Chroma’s IronForge / Sky Portal family

✅ You’re ready for a fixed desk light rather than a travel Mini

Your questions, answered

Mini or 2.1?
Mini is portable with an 8000 mAh battery. 2.1 is the fuller desk model with daytime white plus amber/red evening mode [1].

Is the red the same as IronForge?
IronForge is a dedicated red/NIR therapy device. Sky Portal 2.1 adds 660 nm red in its evening mode alongside amber — different jobs [1].

Do I buy it from Glowing Healthy?
