Amber Book Light Review: Blue Light Blocking Night Reading Light

Quick Verdict

The Amber Light+ amber book light does exactly what its marketing claims: it bathes your page in warm, blue-light-free amber without disturbing a sleeping partner. The battery endurance is genuinely impressive — 30-plus hours between charges — and at 70 grams it's so light you stop noticing it's there. My rating sits at 4.2 out of 5. It earns that score for its core job. It loses half a point for a clip design that still trips you up on certain book formats and a beam narrow enough to feel claustrophobic if you prefer wide-open pages. Read on before you buy.

What Is the Amber Light+ Giftable Amber Book Light?

The Amber Light+ is a clip-on reading lamp built around a single warm-amber LED rated at 1600K. That color temperature is the whole pitch: standard LEDs pump out blue-dominant white light that suppresses melatonin, the hormone your brain cuts off when daylight fades. 1600K sits near the red end of the visible spectrum, so it doesn't trigger that melatonin shutdown. According to the manufacturer, the filter removes 99.95% of blue light — a figure I'd treat as directional rather than lab-verified, but the color temperature alone tells you the shift is real.

The internal 1000mAh lithium battery charges via USB and feeds three brightness modes: 20 lumens (25%), 40 lumens (50%), and 80 lumens (100%). The whole unit weighs 70 grams — about as much as two AA batteries. The design is unabashedly gift-forward, which you'll either appreciate or find slightly wasteful depending on whether you're the end buyer.

Hands-On Review

I unboxed the Amber Light+ on a Tuesday evening, tore through the minimalist instructions — one button, one port, done — and clipped it onto my Paperwhite before my usual 45-minute reading window. The first thing I noticed was the warmth. Not yellow-warm like a desk lamp. More like holding a lit match at arm's length: distinctly orange, softly diffused, zero harshness. My partner, who falls asleep roughly three minutes after I turn off the overhead, slept right through the entire session. That alone justified the purchase.

After two weeks I can tell you the battery life claim holds up. I read most nights at the middle brightness setting and charged the unit exactly twice — once after the initial unboxing, once at the end of week two. That's roughly 14 nights of reading, 30-45 minutes each, with power to spare. The micro-USB port is snug, which is fine for a permanent bedside setup but slightly annoying when you're fishing for a cable in the dark.

The low-brightness mode surprised me. I'd assumed anything below 50% would feel pointless, but 20 lumens is genuinely useful when you're half-asleep and squinting at your last chapter before you nod off. It extends the battery further too — if you primarily read in the final drowsy stretch before sleep, you could stretch this thing to 40-plus hours without trying.

What I didn't anticipate was the clip geometry. On my Kindle the fit is clean — the light sits above the bezel and throws even illumination across the screen. On a hardcover novel, though, the clip's hinge sits right where the spine curves inward. That means text near the binding gets shadowed unless you offset the book, which defeats the hands-free pitch. For paperbacks and e-readers the design works. For thicker bound volumes, you're compromising.

I was also initially skeptical about the "warm as a lullaby" claim in the product copy regarding children's nightlights. Full disclosure: I don't have kids, so I tested this by dimming the light to its lowest setting and leaving it on overnight in a dark guest room. It's not going to replace a proper nightlight — the beam is focused, not omnidirectional — but as a soft reading companion for a child who wants "just one more page" before sleep, it does the job without the blue-light trade-off of a tablet. That's a legitimate use case.

Who Should Buy It?

• Bedtime readers with a sleeping partner — the warm amber glow is directional enough to stay on your side of the pillow without waking anyone
• E-reader owners — the clip locks onto Kindle Paperwhites, basic Kindles, and most standard e-readers without obscuring the screen
• Night-shift workers or late-night readers — if you read after 10 PM and notice it's harder to fall asleep afterward, this eliminates the most disruptive part of that problem
• Blue-light-sensitive readers — whether you track your sleep cycles or just know that bright white light makes you jittery, the 1600K shift is immediate and noticeable

Skip this one if you read physical hardcover books regularly — the clip geometry genuinely fights you on thick spines. Also skip it if you need a light that spreads across two open pages or illuminates a shared reading surface; the beam is strictly personal.

Alternatives Worth Considering

DEWENWILS Book Light — if you want a multi-angle LED design that spreads across two pages, the DEWENWILS model offers three flexible necks instead of a single fixed clip. It's not amber-filtered, but it solves the hardcover problem. Expect shorter battery life around 20 hours per charge.

Glocusent LED Book Light — Glocusent packs three color temperatures (amber, warm white, cool white) into a single unit. Great for versatility, but the cool modes reintroduce blue light, which undermines the sleep-friendliness pitch. Battery performance is comparable to the Amber Light+.

BYBLIGHT Book Light — a budget alternative that strips out the lithium battery in favor of AAA cells. Less convenient long-term, but the upfront cost is significantly lower. Color temperature maxes out around 3000K — warmer than standard LEDs, but not as aggressively amber as 1600K.

FAQ

Final Verdict

The Amber Light+ amber book light earns a recommendation if your primary goal is reading at night without wrecking your sleep architecture. The 1600K amber output is exactly as warm and melatonin-friendly as advertised, the battery life is exceptional, and the weight is negligible enough that it won't shift your Kindle's balance. The clip design holds it back from universal five-star territory — hardcover readers will feel the frustration — but for e-reader owners and paperback loyalists, this thing delivers its core promise cleanly. If you need wider beam coverage or read shared documents, look at the alternatives above. For solo bedtime reading, the Amber Light+ sits comfortably at the top of its category.
