Review dateDecember 2021


The Obulb MCs we are reviewing here is the 3rd Obulb generation. While the first Obulb only had 2 LED colors, the MC added Multiple Colors (see the abbreviation). This is a bit more advanced even, and includes a sensor. If you want to go all out, have a look at the Olight Obulb PRO.

Olight keeps producing interesting ‘light sources’. Be it a pen, a lantern, or an Obuddy, they keep inventing new and cool stuff. On top of the multi-color setting of the Olight MC, the MCs has a few more tricks up its sleeve.

This time, the Olight MCs includes a power adapter with a built-in Magnetic charge system as well as Obuddy, Obulb’s friend.

Package quality

Like all Olight flashlights, the Obulb MCs was shipped in a uniquely designed box with the necessary accessories. The package Olight sent us for review, also included the Obuddy.

  • The Olight Obulb MCs lamp
  • Olight MCA charge adapter
  • Eye- stickers
  • Base with sticker for attaching the magnetic Obulb MC
  • (Osling)
  • Manual

And I also received the following:

  • Olight Obuddy

There was no charging cable included this time. But instead, they included the Olight MCA (a USB charging adapter) with a built-in magnetic charger and USB-A port. This way, you can use the Obulb MCs as a motion sensor anywhere in your house. (Specially great near bedrooms), as well as charging your phone or any other device with the USB charge port.

Flashlight in use

The Olight Obulb is a little lantern, and I believe this is one of the most fun Olight toys for kids. Its predecessor added multiple colors to the already cool Obulb, and the MCs has even more options with the built-in motion sensor, and the addition of the Obuddy and Olight MCA (Magnetic Charging Adapter)

There’s multiple ways of using the Obulb MCs, and one of them is attaching it to anything metal with the built-in magnet. Just stick it to anything and you’ll have your hands free. If there is nothing metal around, you can use the included metal badge, and stick it anywhere you want.

Besides the built-in Magnet and Meta badge, Olight also included the Obuddy, and the Olight MCA charge adapter.

First something about the Obuddy. It’s not just a holder, but a charger at the same time. If you don’t want to use the MCA charge adapter, you can connect any MCC (magnetic charging cable) to the rear and make it work that way.

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 shouldn’t be used to toss in your toolbox.

There’s 2 parts on the lantern. The top part, which is a translucent type of diffuser, and the base with the battery. Keep in mind that the MCs also has a motion detector that will activate the light when plugged in, and in a dark room.

LED, Lens, Bezel, and Reflector

If you like having multiple colors, get the Obulb MC. If you want to use it as a bedside lamp, get the MCs. 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.

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.

Then there is also the hidden random mode/ challenge mode. I don’t really understand the point of it, but it’s in there, just in case you get bored.

Dimensions and size comparison

  • Height :  48.5 mm / 1.9 ”
  • Diameter: 54.1 mm / 2.13 ”


  • Weight in total: 62.1 g / 2.19 oz.

This is a little heavier than the Olight Obulb MC.

Flashlight comparison

Size compared to other Olight lanterns

From left to right: Olight Obulb, Olight Obulb MC, Olight Obulb MCs

Driver & User Interface:

I liked the UI of the first Obulb a lot. A simple click for on/off and along-press for changing modes. Unfortunately, the Obulb MC, and the Olight Obulb MCs likewise, have 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 (and a Random mode and Challenge mode)

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
  • Press and hold 3 sec when in Moonlight mode: turn Motion sensor on/off
  • Press and hold 3 sec in any mode: challenge mode turns on


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

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 from off to activate.. Lock out is actually momentary on in low mode


  • Not visible

Motion Sensor mode:

  • By default, the motion sensor is on, when the Obulb is connected to either the charger, the Obuddy (and charger) or on top of the MCA while plugged in.
  • The output can be manually adjusted by pressing the Obulb while the light turns on after activating in a dark room. Press and hold to increase/decrease the brightness, till the point you want it to be. Simply release the Obulb and the output is memorized. Next time you move in a dark room, the light will turn on in the manually set output.

Challenge mode:

  • I really have no idea how to use it, and at the moment I think it’s a bit pointless. If you know how to use it, or better, how to enjoy it, let me know.

Firmware / UI Conclusion:

I still like the original Obulb a lot, and still prefer it over the MC and MCs. Single press for on and off.

Olight MCA, Olight Obuddy & Charging

Olight includes the Olight MCA (Magnetic Charging Adapter) instead of the normal MCC (Magnetic Charging Cable). The adapter looks like an every USB power plug, but with an Olight magnetic charging ring on top.

When the charger is plugged in, and the Olight MCs is attached to the magnetic charging thing, the Olight will behave like a motion sensor. When the room gets dark enough, and it notices movement, the light will activate. You can also deactivate the motion sensor by doing the following:

  1. Turn the light on
  2. Go to the low output mode
  3. Press and hold for 3 seconds
  4. After 3 seconds, a green light will tell that the sensor is activated and a red light will tell that it is deactivated.

Olight Obuddy

The Obuddy behaves the same as the MCA while connected with the MCC charging cable. It’s just another way to plug it in, and activate the motion sensor.


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 lumens65.2565.25 lumens


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. I also included the Olight Obulb MC runtime graph for comparison.

High is a little short of 4 hours, and Low is good for 37 hours and 22 minutes. A few hours shorter than the Obulb MC.

Throw Measurement

No measurements were taken.


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 adapter
  4. Includes an motion sensor (works when plugged in)
  5. Obuddy is another great option for the Olight Obulb


  1. Single click to change modes instead of on/off
  2. Charging speed is low
  3. Its not clear how to use “challenge mode”
  4. Obulb doesn’t work when attached to the Obuddy, without being plugged in

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

5 stars: ★★★★★

The Obulb MC is a nice little lantern, especially for kids. And with the new motion sensor built in, it makes it an even better gift! You can use the motion sensor with the included Olight MCA (Magnet Charging Adapter), or with the optional Obuddy.
