Olight O Bulb Plus Review: A Palm-Sized Ambient Light With Surprising Depth

Introduction

Olight has been developing its O Bulb line for a while, and the O Bulb Plus represents the fullest version of the concept yet: a tiny, palm-sized orb of light that punches well above its dimensions. The design is deliberately simple, and the company has even leaned into a bit of humor, including stick-on eyes in the box. But beyond the charm, this is a genuinely capable ambient light with touch controls, a companion app, and a maximum output of 300 lumens.

The core experience is refreshingly uncomplicated. You tap, hold, and double-tap, and the light responds. Deeper features live in the app, where you find color presets, brightness sliders, and a few unexpected extras. This review walks through who it suits, what it does well, and what to weigh before picking one up.

Who This Product Is For

The O Bulb Plus is best suited to anyone who wants a portable, flexible ambient light rather than a dedicated task lamp. Campers and van owners get a lot here: with roughly a 30-foot Bluetooth range, you can leave the light inside a camper or tent, control it from your phone, and fire up to 300 lumens of brightness on demand. That is plenty of light for a small interior space.

It also works as a tabletop light at home. The preset modes, including flame, romantic, fireworks, and aurora effects, turn it into something closer to a mood lamp than a utility light. If you only ever need one fixed brightness level, this may be more light than you need, but for people who like options in a tiny package, it fits well.

Main Strengths

The headline strength is the combination of size and output. At 300 lumens maximum, this little orb is seriously bright for its class, and the standard settings step down through 180 and 40 lumens so you can match the level to the situation.

The touch-sensitive top is another standout. Unlike earlier designs that used a push button at the bottom, this version senses input even when it is not resting on a surface. A press-and-hold adjusts brightness, a single tap cycles through modes, and a double tap shuts everything off. The interface is easy to internalize within a few minutes of use.

Then there is the app. Using the O Hub app, the light connects over Bluetooth and unlocks a broader set of controls: on/off, a brightness slider, a long list of color presets, and quick access back to plain white at maximum or minimum. Olight has also slipped in a few playful touches, including a whack-a-mole style game and a mode that reacts to music. None of these are essential, but they give the light a personality that most portable lamps lack.

Things to Consider Before Buying

A few practical points are worth thinking through. First, the touch controls are sensitive by design, which means accidental inputs are possible if the light gets jostled in a bag. It is worth learning the double-tap off gesture early so you are never caught out.

Second, the more advanced features require the companion app and a Bluetooth connection within roughly a 30-foot range. If you prefer fully standalone hardware with no phone involved, the onboard tap and hold controls still work well, but you will miss out on the color presets and remote operation. Finally, the maximum 300-lumen output is strong for a light this size, but it is an ambient and area light, not a long-range flashlight. Set expectations accordingly.

Buying Advice

If you want a portable light for camping, a camper van, or casual use around the house, the O Bulb Plus covers an unusually wide range of needs in one small object. The straightforward tap controls handle everyday use, and the app unlocks the flame, aurora, fireworks, and music-reactive modes when you want something more atmospheric.

For serious buyers, the app is where the long-term value sits, so it is worth exploring the full preset list before settling on how you plan to use the light. If you mostly need plain white light at a few brightness levels, the onboard controls alone justify the purchase.

Conclusion

The Olight O Bulb Plus takes a simple idea, a glowing orb, and executes it with more depth than expected. Bright for its size, easy to control by touch, and genuinely fun through its app, it is an easy recommendation for campers, van dwellers, and anyone who enjoys a well-made piece of ambient lighting.
