Mr.Go 4-inch Cube Light

*(for 4-inch version)* >LIGHT: I am very pleased with the light output of this cube. The colors are rich, and pleasingly fill up most of the cube's volume, getting only a bit dimmer in the cube's lower 1/3rd or so. The "white" color setting is especially good, since it is quite truly white (not blue-tinged like cheap LEDs can be). At max brightness, the cube is definitely bright enough to light up a room (depending on color choice), but only perhaps to about the level of a small desk lamp. Meaning, it won't replace central room lighting or anything. The brightness adjustments also maintain the integrity of the chosen color very well. I also own a competing RGB LED lamp purchased here on Amazon, and when changing the brightness on that one, the overall hue/color changes drastically. This cube doesn't do that - the colors stay true when changing the brightness. Also, contrary to the description, there are quite definitely 8 brightness levels (not 5), which I consider to be a good thing. >BUILD: The cube itself is very solid, but there is a slight rattle inside when moving the cube... This hasn't caused any noticeable problem, though. There are no rubber feet/bumpers on the bottom of the cube - it just rests right on the main plastic shell when set down, and is a bit slippery. Other reviewers have mentioned that the charging port is on the bottom, which means the cube must rest on its side if used while charging. I don't see this as much of an issue, since the only other design adjustment would be to put the port on the side, and this would break up the clean aesthetic of the whole cube. >BATTERY LIFE: I haven't timed it in hours, but this is now two weeks after the initial charge, and I've used the cube almost every night as a "winding down for bed" nightlight, and it's still going... I consider that to be quite good. >REMOTE: Honestly, the remote feels a bit cheap. It's an infrared remote (like a good old-fashioned TV remote) so you definitely have to point it at the cube, with nothing obstructing it. That aside, the range/responsiveness is pretty good. When turning the cube on, I almost always have to push the "on" button twice before it responds. Not sure if this is to overcome some sort of battery-saving sleep mode...? Every other setting adjusts with the first press of the appropriate button. >CONCLUSION: I would recommend this cube to others, and I see myself probably buying more at some point. It does what I wanted it to do, it does what is advertised, and it does it all reliably with only mild gripes. A solid product. P.S. There was an issue with my cube when first received, and Mr. Go's customer service responded in about an hour with a completely satisfactory solution, even though the problem was determined to be Amazon's fault. EXCELLENT customer service.

Very relaxing. Nice, smooth color fade.

I recently got my hands on the Mr.Go 4‑inch Dimmable LED Night Light Cube, and I’ve been pleasantly surprised—this little cube packs a lot more personality than its size suggests. First off, it’s ridiculously easy to use. It ships with a slim remote that lets me cycle through 16 vibrant colors, adjust brightness across eight levels, and toggle between four lighting effects like flash, strobe, fade, and smooth. Whether I’m setting a soothing blue glow for bedtime or ramping up party vibes with pulsing hues, the controls are intuitive and responsive. The rechargeable lithium-ion battery is solid—Mr.Go claims 8 to 48 hours depending on settings, which lines up with my real-world use. I can go multiple evenings without recharging, and when it does die, it takes just a couple of hours to recharge via USB. It’s fully cordless and IP65 waterproof, so I’ve even used it by my shower, worry-free. I appreciate how durable and kid-friendly it is—cool to the touch, BPA‑free material, and tough enough to survive a drop or two. My niece loves carrying it around in her room; it’s the perfect “companion light” for bedtime. On the flip side, since it’s made of hard plastic, the light output is diffuse rather than sharply directional, which means it's more for mood lighting than reading at night. And while the remote is convenient, I sometimes misplace it. A small button on the unit itself helps, but I wish it offered a touch sensor or app control option. Overall, I’d say for anyone looking to add a bit of color and ambiance—whether on a bedside table, patio, or kids’ room—this cube is a charming, reliable, and affordable pick. It’s not a reading lamp, but it excels at setting a vibe without fuss or fussiness.

The first one was defective but the company replaced it immediately and the new one works great

I love this little cube but one complaint-to make it waterproof, there’s a little flap/cover that goes over the charging port where you plug in the cord to protect it. When my cube arrived this cover was broken-I found the little piece in the box, looked like it got ripped off. It’s made of a rubbery material, not sure if this was mishandled or just defective. I don’t think this thing is really waterproof anymore-which is a bummer if you wanted to be able to bring it outside. Didn’t reach out to Amazon because the hassle of sending this one back didn’t seem worth it. Make sure to inspect yours, especially if you’re bringing this outdoors and need that little water-proofing piece. Otherwise though this thing is very cute and I like the variety of the brightness settings-there’s a big difference between the lowest and highest and the colors are vibrant. I would consider buying another one in a different size eventually because they’re so cute!
