Olight Obulb MC Multi-Color Lantern Review

Olight Obulb MC Multi-Color Lantern Review

The Obulb MC is a new “bulb” lantern by Olight with multi-color features! It uses the standard Olight charger, and has a neat carry handle!

Official Specs and Features

Here’s a link to the Olight Obulb MC Multi-Color lantern product page.


There’s just one Olight Obulb MC Multi-Color lantern, but there are options.  The first option is body color – black, white, or brick red (seen here).  You get to pick this option.  The second choice is with the Osling (you’ll see later):  blue, white, or red.  The color here is chosen randomly; you do not get to pick.


Olight has a sale going right now that puts the Olight Obulb MC Multi-Color lantern at $23.96, including Osling.

Short Review

Every time I’ve seen these before, I’ve just overlooked them.  This Obulb MC is my first Obulb of any sort, and I have to say, I really, really like it.  The very warm temperature of white output is great as a nightlight.  And with full waterproofness (and ability to float), it’s a very fun toy!

I’m not going to test the Olight Obulb MC Multi-Color Lantern with runtime graphs, and charge graphs…. At $24, it’s very easy to say you need one of these.  Even if you have opinions about Olight.  Even if you don’t need one.

It’s really just too fun to pass up.

I only learned after using the lantern for a while, that despite having exposed charge contacts, this thing is “so fully waterproof” that it can be used as a floaty light in a bathtub!!

If the flashlight will headstand, I’ll show it here (usually the third photo).  If the flashlight will tailstand, I’ll show that here, too (usually the fourth photo).

Here’s the test light with the venerable Convoy S2+.  Mine’s a custom “baked” edition Nichia 219b triple.  A very nice 18650 light.

And here’s the light beside my custom engraved TorchLAB BOSS 35, an 18350 light.  I reviewed the aluminum version of that light in both 35 and 70 formats.

Retention and Carry

I honestly thought this little metal coin was just that – an Olight challenge coin of sorts.

But no, this thing cleverly has a sticky back, and can be stuck somewhere…  Couple that with the magnet base of the Olight Obulb MC Multi-Color Lantern, and you have a “stick anywhere” (once) base for placing the lantern!  I find that to be exceptionally clever.

Of course, the magnetic base of the Obulb MC itself can be stuck to more places than just this metal sticky thing.  The magnet holds the Obulb MC very securely.

The second option for carry is the “Osling.”  Mine came in a separate package, and according to the fact that Olight says you can’t pick a color, your Osling will probably be separately packaged too.  Mine’s white.  Maybe translucent, or opaque.

It’s very silicone-y, and overall…. again better than you’re probably thinking it is.  It’s very compelling.

When in the Osling, the Obulb MC can still be charged.  The Obulb MC can go into the Osling the other way too, and maybe have more water protection.

The charging base for the built-in battery in the Olight Obulb MC Multi-Color Lantern is the standard Olight MCC 1A.  This is the same as any other MCC charger, and any of those will work too.

I’ll throw in that when the Obulb MC is sitting on a flat surface, the button can’t be pressed by pushing down on top of the Obulb MC.  But when on the charging base, pushing down from the top does actuate the switch.  This is a nice feature.

There are also other charging bases available now in the MCC format.  One is built into the side of a wall wart, such that the Obulb MC can be used very much like a nightlight.  Unfortunately, in what testing I could do (without this type of charger), it does not seem to come on when the power goes off.  This would be a great feature.

One more option for charging this Olight (or really “any” Olight with this type of connection) is a charging base that has room for four items at one time.  I don’t have one of those either, so no testing on that, too.

Modes and Currents

Mode Mode Claimed Output (lm) Claimed Runtime
White High 75 3h
White Low 3.5 40h
Color Fantasy 3-7 7h

Pulse Width Modulation

None of the outputs have PWM.

For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor.  Also, here’s the light with the worst PWM I could find.  I’m adding multiple timescales, so it’ll be easier to compare to the test light.  Unfortunately, the PWM on this light is so bad that it doesn’t even work with my normal scale, with is 50 microseconds (50us).  10ms5ms2ms1ms0.5ms0.2ms.  In a display faster than 0.2ms or so, the on/off cycle is more than one screen, so it’d just (very incorrectly) look like a flat line.  I wrote more about this Ultrafire WF-602C flashlight and explained a little about PWM too.

User Interface and Operation

The switch is on the bottom of the device.

It’s an e-switch, and I think the user interface will be very familiar.

Here’s a UI table!

State Action Result
Off Click On (Mode Memory)
Off Hold On (White Low)
On Click Mode advance (White Low > White High > Red > Green > Blue > “Fade between colors” > Cycle between colors > Flashing Red > Off
On Hold Off
Off Click >20x “Special mode” where “flowing colorful light appears, and the speed slows down over time.”  Switches to White Low after 30s.
At random. (I was unable to activate this mode!)
Off Hold >2s Lockout (indicated by short flash)
Lockout Hold >1s Unlock to White Low

LED and Beam

Nothing about the emitters is specified by Olight.  There are some interesting results below, though.

LED Color Report (CRI and CCT)

I tested all the steady colors.  They’re in order of appearance through the mode cycle (which can be seen in the UI table above.

White Low > White High > Red > Green > Blue

My spectrometer didn’t know how to report the Green and Blue, so I made those two reports in a more manual way.  I’m extremely pleased that the white mode is around 2500K.  It’s …. super perfect.  I could not be happier with that emitter.  CRI is 86 too, so not even all that bad.


These beamshots are always with the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure.  You’re not expecting much.  Even the 75 lumen output level is so floody, it’s nearly impossible to see on the ceiling.

Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)

I keep the test flashlight on the left, and the BLF-348 reference flashlight on the right.

I compare everything to the KillzoneFlashlights.com 219b BLF-348 because it’s inexpensive and has the best tint!

Go buy the Olight Obulb MC Multi-Color lantern at $23.96, including Osling!!


What I like

  • Easy access to White Low
  • 2500K CCT on the white is fantastic
  • Floats!
  • Easy user interface
  • There are some fun modes with the colors
  • Osling seems gimmicky but is actually quite neat
  • Actually, the whole thing seems kind of gimmicky, but honestly, it’s great
  • Magnet base works very well
  • Very floody output
  • Low cost

What I don’t like

  • Special mode sounds neat but I couldn’t access it
  • Pretty much nowhere to hold on to the thing, except to completely hold the thing.

  1. It looks like the special mode happens at random. So I guess if you press 20 times, and repeat that 10 times, there is a high chance to access it
