Olight keeps producing interesting ‘light sources’. Be it a pen, or a lantern, they keep inventing new and cools stuff, including the Olight Obulb MC. MC stands for multi color, because this Obulb does a few tricks, including a red, green, blue colors, also a special color wave mode, and a color blinking mode.

Package quality.

Like all Olight flashlights, the Obulb MC was shipped in a uniquely designed box with the necessary accessories. This is what you get:

  • The Olight Obulb MC lamp
  • USB charging cable
  • Eye- stickers
  • Base with sticker for attaching the magnetic Obulb MC
  • (Osling)
  • Manual

Flashlight in use

The Obulb is a little lantern, and I believe this is one of the most fun Olight toys for kids. The Obulb MC is the successor of the Obulb, with multiple colors. To turn it on, you simply press the bottom of the lantern (the place where you attach the magnetic USB cable).

There’s multiple ways of using the Obulb MC, and one of them is attaching it to metal with the built-in magnet. Just stick it to anything and you’ll have your hands free for repairing some stuff or reading a book at night. One thing that I think is a pity, is the UI. Clicks will change modes, and a long-press will turn the light off/on. I’d prefer the click for on/off.

Besides the magnet, Olight included the Osling (read O Sling), which is a translucent, silicone lanyard that you can insert the Obulb in. Quite a neat little thing to be honest. This way, you can actually carry it, or hang it in your tent. You also get to choose in which direction you insert the Obulb, so you get complete control of the direction you want the light to point.

Oh, and I almost forgot to mention the adhesive metal badge Olight includes. If there’s nothing metal to stick it to, you can use the metal badge, and stick it to wood or plastic, and get yourself a place to stick the Obulb to.

Build Quality, and Warranty

We’re not talking about a regular flashlight, but a plastic lantern that is likely focusing on a specific audience: kids. I’m not saying these are just great for kids (because I like the previous Obulb a lot), but I hope you get the point. It’s made of plastic, and should be used to throw or toss in your toolbox.

There’s 2 parts to the lantern. The top part, which is a translucent type of diffuser, and the base with the battery.

LED, Lens, Bezel, and Reflector

If you like having multiple colors, get the Obulb MC. If you simply want a High, Low, and a hidden red mode: Get the original Obulb.

There’s no LED visible, so I can’t really tell much about the type of LED. There’s no bezel or reflector to talk about either. All I can see this is not your regular type of flashlight.

Besides a High and Low white light, you get a red, green, and blue led. The next mode is flowing colors, a mode with blinking colors, and a red blinking mode. So 5 constant color modes, and 3 special modes.

Driver & User Interface:

I liked the UI of the first Obulb a lot. A simple click for on/off and long-press for changing modes. Unfortunately, the Obulb MC has a different UI, with a long-press for on/off, and clicks for changing modes.

Available modes:

  • White Low, White High, Red, Green, Blue
  • Special modes: Fading colors, blinking colors, blinking red

From OFF:

  • Single-click: to last used mode, mode memory, all modes
  • Double click: just jumping to next mode after memorize mode
  • Press and hold 1 sec: to low mode (white)
  • Press and hold 3 sec: lock out mode

From ON:

  • Single-click: change modes
  • Double click: nothing, just skips to next modes
  • Press and hold: turn off


  • To Turbo: none
  • To Low: press and hold from Off
  • To Strobe: none

Mode memory:

  • Yes, but with long press from off will go directly to Low

Blinky modes menu:

  • Yes, and they are also memorized

Low battery warning:

  • There’s a low battery warning: the light will blink when the battery runs low.

Lock-out mode:

  • Yes, press-and-hold for 3 seconds to activate.. Lock out is actually momentary on in low mode


  • Not visible

Firmware / UI Conclusion:

I’d prefer to have a long press for changing modes, and a single click for on/off.

There’s also a hidden Special mode, where you have to click the switch 20-200 times in 5 seconds, but I couldn’t do it, unfortunately.

Batteries & Charging

Olight includes a magnetic charging cable. The magnet connects to the charging base (bottom of the obulb) with a magnet. There’s a small indicator LED to show the charge status. Red=charging, Green=finished charging

Seeing green would make you feel the battery is fully charged, but in reality, it still charges at a very low current till it is really full. The current reduces till it is fully charged.

The charging cable is labeled: MCC 1A (which is different from the cables included with the 18650 and 21700 flashlights, and charges slower).


Lumen measurements:

All output numbers are relative for my home-made Integrating Sphere. It is set up with an Extech SDL400 Lux Meter for measurements including a Kenko PRO1D ND-16 filter. The base measurement is done with a Convoy S2+ that has been tested at 255 lumens.

Specifications lumens @ 30seclumens @ start
High75 lumens76.90 lumens77.19 lumens

These numbers are pretty close to specs.


The runtime test was done with the 50cm integrating sphere, including the Kenko Pro1D ND-16 filter and Extech SDL400 data logging Lux Meter.

This is a pretty boring runtime graph. But here you go:

High is a little short of 4 hours, and Low is good for 42 hours and 21 minutes.

Throw Measurement

No measurements were taken because of the nature of the beast.


Disclaimer: This flashlight was sent to me for review at no cost by Olight. I have not been paid to review, nor have I been holding back on problems or defects.

Final Verdict


  1. Great for kids
  2. Magnetic base
  3. Includes charging cable
  4. Includes a Osling (translucent lanyard for Obulb)


  1. Single click to change modes instead of on/off
  2. Charging speed is low

Explanation on star ratings:

1: Avoid: my phone flashlight would be a better choice – 2: Poor: significant defect or issues, much better options available at the same price – 3: Average: some defects or issues – 4: Good: recommended (minor issues) – 5: Great: highly recommended

4.0 stars: ★★★★★

The Obulb MC is a nice little lantern, especially for kids. But for my use cases (and my kids) the original Obulb was even nicer with a single click for on/off, and long press for changing modes.

The Obulb MC is a multi-color lantern that can be a great gift for kids who love to go camping.
