Review: Olight X7 Marauder

Thank you for an informative review.

Correct me if I am wrong, but it seems from the photographs that non-protected batteries need to be button-top is this correct?

Also is their a range on the length of the battery to work in this light?

Lack of information? I don’t see it at criticism. In fact, I have this test on its way.
However, consider the following:

- how do you identify the 50% level of a battery?

- if you can identify that voltage, how would it be compared to the ones of other batteries?

- the result you get from your test, done at RT, can be the same when the cells are 50%… but have been charged quicker? or you are in the freezing snow?

  • all the above, how will it compare to other batteries? If you have 3500mAh that are able to get turbo only above 50% charge, would you rather run 2100mAh that are able to get turbo only above 20% charge?
    You just CAN’T have enough information.

After the runtime at mid mode, I’ll run the “50%” test.

Thank you for a prompt reply and again for a very good review. :slight_smile:

You are welcome.
Also, the on-off test is very very tricky.
Simple to do, but how do you do it?
at Room temperature? with a fan?
how well does the light in between these conditions?

Yes, the users does on-off many times, but how many times do they on-off at RT, on a table? or in front of a fan? in winter? or summer?
what will happen in winter, where you get extra heat removal, but lower battery efficiency? And vice versa?
with a temperature sensor the interpretation that you can get from the data, is very “situational”.

What I would do is do a runtime test, but in ~5min (or 2min) intervals, allowing enough time for the light to cool between intervals. This would simulate more closely actual usage. Of course, you are right it might perform differently with different cells.

I don’t like the 5 minutes, I prefere to do it closer (30”).
Again, I like to make the “worst” situation, so you should at least expect something better.

Consider also this. I can make the test , but my test are run with the light sitting on a table.
If you keep your hand on the light, you actually make it cooler.

Everything is relative.

Yesterday 9/21 was on my calendar (unspecific to location) said it was the Autumn Equinox, but in my location it will not occur until 9/25; four days later.

A good example of relativity in a flashlight test, as Budda has just written, is that there is a difference between holding a light with your hand and having it mounted. :slight_smile:

All these variables have an impact on test results. This is also one of the reasons that car mileage tests are done in laboratories. The side effect is that unrealistic scenarios where ridiculous low acceleration values are used etc. The outcome is a set of unrepresentative data. It’s hard to come up with standard test methods. I’m very happy with the runtime graphs produced here, and the only additional interesting thing I would like to know (asked Maukka yesterday) is whether the full 9000 lumens can be achieved with semi depleted cells (answer: no, only about 4500 lumens). Anyhow, thanks a lot Budda for the hard work! :wink:


For this test I had to let my hand on the light for the whole test.

Budda thanks for the review, excellent product of Olight.

I like the way you think about worst situation.
Thank You Budda, I think I fall in love with this light :slight_smile:

should be online in half an hour, or so

Is this normal behavior when shutting down the light?

Thanks for the awesome review OP, btw.

Perfectly normal leds shut down at varying voltages, so yes, that could be normal behaviour.

My R50 Pro and X7 both do that.

Nice review Budda, thank you for good details.
Even if is not a new model anymore, few days ago I receive mine.
Was hard to choose between Olight X7 and Acebeam X45 (even if is a big difference in throw, I was looking for a big lumen light ) , the thermal control was the main reason why I choose the X7.
I absolutely nice to know that in some circumstances you can leave the flashlight unattended even on highest level . In real life situations this can be happen, and is unacceptable (for me) to can not touch the light (X45 can reach more than 90degrC unattended… ) .

On long period I’m not confident in the rubber switch if have an intensive use, but seems to be good quality rubber.
Also I wished to have a tripod support because X7 is very suitable also for camping.

I use Samsung 30Q with 3mm neodim magnets, works perfect, at 3,6V (rest) is still able to provide TurboS.
At 3,3V the main levels still work (even 3000 lm)

Hello Budda, thx for the review.

Can you give me the exact diameter of the thread in the bezel? I need it to mount a photographic ring.
Maybe I can mount it inside the bezel or in its place?

Thx
