REVIEW - Rofis MR30 - rechargeable and dischargeable - 21700 battery

Review copy was sent in by Rofislight to me here in Italy, whom I thank very much.
Site page: http://www.rofislight.com/products/rofis-mr30/

Premise:
1) last spring Rofis asked me if I wanted to review their new R3 (I had already reviewed the R1 and the MR70) and I said ok, asking to review the R2 as well, to complete the series;
2) after more than a month, seeing that nothing was coming, I contacted Rofis; they assured me that they would make another shipment; also the second shipment had no results;
3) after a long time, in early September, Rofis asked me if I wanted to review their new MR30 and again I said ok, recalling the problem of R2 and R3 non-delivery, without receiving any answer to this last observation;
4) on October 10th I found in the letterbox a notice of non-delivery a parcel from Singapore, available at the post office, after two days: I understood it was Rofis expedition;
5) on October 12 I went to the post office thinking to get only the MR30, but, to my surprise, from box came out R2 and the R3 too:

so now I have three flashlights to review!

Let’start from MR30 (and sorry for my bad English!)

The first element to highlight in this last child at Rofis home is 21700 battery power supply, in order to have only a slightly larger tail diameter than flashlights using 18650, but moooore runtime. Wink
It’s a relatively new battery size, but already used by other brands (see Manker U22, Acebeam EC65/T36, Wuben A21, Astrolux FT01/FT02, etc.) and by the same Rofis in MR50 model.
The second element to highlight is CREE XHP35 High Intensity Cool White led, in order to deliver maximum candela, in a throw-flashlight.

in following image are briefly summarized all the characteristics and operation modes (according to Rofis):

here is the full text of the instructions manual:
___________________________________________________________________________________________________________________________
Main Features:

  • Uses a 21700 5000mAh high-rate discharge lithium battery.

2) The green indicator light flashes continuously 3 times, indicating the remained capacity of the battery is 50%-79%.
3) The green indicator light flashes 2 consecutive times, indicating that the battery power is 20% – 49%;
4) The green light flashes, means the remaining battery power is less than 20%;
5) When the battery power is less than 5%, stop charging the external device.

IV Explaining Matters
When the battery power is less than 2%, the flashlight stops working.

Here’s how it comes and what’s coming:

packaging:


in the box: flashlight with included 21700 5000 mAh battery marked Rofis (total weight with clip 152 gr.) – cable for integrated battery charging (microUSB – USB male length 52 cm.) – microUSB – USB female cable length 9,8 cm., wich, coupled with integrated charging cable, convert MR30 in a power-bank (this cable is an OTG adapter, which can also be used to connect smartphones or tablet to accessories such as pendrives, external hard disks, cameras, mouses, keyboards and in some cases even printers) – holster (weight 24 gr.) – lanyard – transparent sachet with spare microUSB protection cover and two spare black 21/24 O-rings – manual in English, Chinese, French, German, Spanish, Italian and Japanese – warranty coupon

inside flashlight 21700 5000 mAh protected battery (weight 74 gr. – diameter 21 mm. – lenght. about 76 mm.), with the negative terminal protected by contacts by a transparent plastic tab

Battery details:


battery positive terminal:

dimensional comparison with some 18650 (protecteted/unprotected) at my disposal:

dimensional comparison with two 26650 unprotecteted:

I tested MR30 with 18650 batteries at my disposal: Eagletac (68.5 cm length), Nitecore (69 cm length) and Rofis (68.8 cm length) and it works; it doesn’t work with flat-top Samsung Q30 (65 cm length), because it dances inside and circuit doesn’t close.

To use 18650 unprotected batteries, 65 cm. I found these adapters:

while charging, red indicator in the middle of the button lights up; green indicator lights up when charging is been completed:

charge time for battery completely discharged with the supplied USB cable goes from 4 hours and 30 minutes to about 5 hours
charging current reaches max. 2 A
flashlight is equipped with Low Voltage Protection circuit

flashlight exterior look:

details:

glass AR treatment, OP reflector and Cree XHP35 HI led:

tailcap detail:

body thickness:

contact to positive terminal detail:

threads detail (sliding and well lubricate)

as you can see in following image grommet of microUSB door follows perfectly the flashlight profile: it’s a little difficult to lift it (better for waterproofing):

micro-usb port and its cover:

the contents of the sachet:

but what is this?:

spare micro-usb cover:

cables:


with attached lanyard:

holster:

Note fixed ring (sewed) and M.O.L.L.E. attachment with double security, automatic button and velcro:

N.B.:thanks to elastic band flashlight doesn’t move from its holster, even upside down

flashlight inside holster in both positions:

when battery power is too low, red light start flashing:

using as power-bank:

during use as a power-bank flashes of green light indicate remaining battery power (in the GIF with 4 intermittent flashes it is more than 80%):]

dimensional comparison with some 18650 flashlights in my possession (from left: Zebralight SC600w MkII L2, Convoy S3, Rofis R3, Convoy L4, Rofis MR30, Solarforce L2P, Emisar D4):

dimensional comparison with two 26650 flashlights in my possession (from left: Rofis MR70, Rofis MR30, Haikelite SC02):

Reduced diameter of tailcap allows me to use flashlight holding between index and middle like a cigar and at same time helping me with a trekking pole in mountain walking

my runtime test (indoor – temp. 20°C – Rofis 21700 battery):

Turbo/Mid:

other tests:

PWM: at low level, detected to the naked eye:

its first little bath:

after half an hour soaking, (condition much more difficult than possible in real use, in my opinion), I don’t detect any infiltration or trace of condensation, even in microUSB socket )

Some indoor beamshots (shoot distance from wall: 50 cm.; spill diameter at this distance is about 76 cm.:

spill angle:

Holding flashlight parallel to the ground at a height of one meter, spill starts at about 140 cm. from feet

Outdoor beamshots:
daytime scene:

Drawing conclusions from my tests with Rofis MR30, in my opinion, real throw is about 180 meters

Conclusion

What i like:

  • contained weight and dimensions, for a flashlight with such an extended runtime;
  • 21700 protected rechargeable battery included;
  • power-bank function;
  • excellent anodization – excellent grip / handling;
  • solid construction;
  • sliding threads;
  • responsive button in a balanced way;
  • output max 1600 lm;
  • OP reflector;
  • two-way clip
  • location mode
  • good beam geometry, with pleasant tint (CW without dominant, with yellowish spot);
  • battery charge level indication (especially in power-bank function);
  • LVP protection circuit for use with unprotected cells, which near the lower limit value of the voltage, stops the supply;
  • range of infinite use;
  • wellmade holster included;
  • aesthetic;
  • very interesting price, considering the constructive level, functions and equipment;
  • tailstand possibility

What I don’t:

  • only CW color available: I would prefer a version with NW color (5000 K);
  • High level with timed step-down (from about 750 Lm to 450 Lm after 7 minutes): this configuration is incomprehensible to me; it would have made sense to separate the two levels, being 450 Lm. (H1 – flat) the most usable level and not being immediately accessible, having to wait for step-down, IMHO is really annoying. A High level of 750 Lm. (H2), on the other hand, could also be useful with stepdown, when necessary to have more brightness for a few minutes;
  • PWM at Low level

At last my final evaluation:

Would I recommend it? Really, I don’t know!
It is a nice multipurpose flashlight, to be kept at home or in a garage/car or for outdoor use, with its great autonomy – suitable for those who practice hiking and camping, but could also be of interest in searching, law enforcement, inspection industrial areas, and other endless everyday uses, constructively solid, and it seems to me that between 21700 flahlights out there is the less expensive, even considering equipment and functionalities
but
I’m afraid that the High level with stepdown, for which I expressed strong perplexities just above, can be a deal-breaker for many people (… or not?).

Thanks for reading/watching my review (the tenth I did, but the first in BLF) and forgive my bad English.

I leave you with some photos taken in the woods:

Great review – Thanks

I think the stiff red wire you mention in the contents list (“but what is this?”) is to aid in threading the lanyard onto the light

just fold a 6” piece of dental floss around the lanyard. Feed the thin floss through first and pull the lanyard through…works every time on any type of lanyard hole.

No risk of damage with a needle or anything metal.

I think you’ve missed the boat.

I posted the vipon deal a few days ago for the MR30 and there was an additional 10% off coupon available from the seller, which is no longer there when I checked it moments ago.

Nope, lucky for me the ‘Vipon Coupon Boat’ had not sailed. Wink . I got it for $29.97 using the Vipon Coupon.

But as you stated, the additional coupon from the seller was gone. I think that would have got it down to $23 & change. Oh well, live & learn. Smile

For the life of me I can’t figure out how I have not heard of Vipon until today. Facepalm

I appreciate you guys sharing this so I can spend some more money. Cash . Cash . Thumbs Up

Received my MR30 last night. I’m very pleased with this light so far. The emitter may be cool white, but it’s quite good- not the harsh blue of some lights (Wuben TO46R comes to mind). I was worried about mikobiker’s comment “PWM: at low level, detected to the naked eye:”, but I’m happy to report that my eyes don’t see the PWM at all.
The protected cell that comes with the light is too long for my Opus BT-C3100, XTAR WP-6, XTAR Dragon, and MiBoxer C8 chargers, but it fits easily in the new MiBoxer C4 Plus charger. And, of course, the lights internal charger works just fine.
One very nice feature is that while the light is plugged into the USB charger, you can still turn the light on. It is a single mode light and appears to be on the medium level. You can even remove the battery and the light will still work just on USB power alone.
I hope the next version of this light uses a USB C port. That’s about the only thing I want changed.

Thanks mikobiker for the review and all those great pics. I got my MR30 recently from an Amazon and Vipon good deal. I didn’t think I’d actually use it. It’s not the brightest. The tint is white which I’m fine with but usually I edc more neutrals. It’s kinda big for an edc. There’s no moonlight. The UI forces holding the button to change modes. The button is nearly impossible to feel in the dark. I mean there is a lot not to like, however I really like the knurling on the body tube and it feels good in the hand. I keep it on high and carry it in the holster. Again I’m not sure why I have been carrying it quite often. Can you tell me why, have I been hypnotized? TIA

Mine was waiting by the front door when I just now got home. It sure looks to be an impressive little light!! Well packaged, plenty of accessories (21700 Battery, USB Cables, sheath, lanyard, spare rubber parts, & instructions) & fit n’ finish appears perfect.

Charging battery now. Wink

Edit: Battery charged, by on board USB charger; to 4.16 V. Not bad at all.

I am liking this light. It is my first ‘21700’ light too. Wink

The light is awesome but the mode spacing is horrible

If they add a 0,7lm mode, add the 450lm mode to the mode secuency and make the 750lm the Max sustained mode, the light will be almost perfect. A 2 min step down instead of 1m would be good too

I like the MR30 so much, I bought 3 of them: one for me, one for my wife, and one more for me Big Smile
So I was bummed when the switch stopped working in my first light after just a couple of weeks of very light use (me playing with it).
Turned out to be an easy fix. I clamped the head in a vice with several layers of heavy paper for protection, then I twisted the body tube out with a large pair of pliers using one of those rubber, jar lid opener pad, thingies between the pliers and the tube for protection.
After that, the driver just drops right out. I did not disconnect the leads to the emitter; there was enough slack to get to the switch. I cleaned the switch with a Qtip and Isopropyl alcohol and the light works good as new.
You can see some of the strands from the Qtip in these pictures.

Edit- 10 minutes later the switch is flaky again. I’ll have to do some micro solder surgery if I can find a replacement switch. Tired

Edit 2- Sent an email to Rofis support asking them to send me a replacement driver. Got a response 25 minutes later. Looks like they are mailing me a new driver Thumbs Up

I got 2 of these from Amazon US I'm in the UK.

 

Should they come with spare O rings and a spare USB cover?

Mine came with spare rings, spare USB cover, lanyard, and 2 USB cables: one for charging and one for powering other devices from the light.

I have two of these lights and like them quite a bit. The UI takes a little getting used to but it’s not bad. The cell however has some issues in both my samples. The light wont sustain Turbo at all unless the cell is fully charged and won’t go into Turbo at all even for a second if it’s not. I put in the Red Vapecell 4200 and a Samsung 40T and both work perfectly. It’s a little disappointing that Rofis selects a cell that doesn’t perform well in their light. I can’t even use the cell in other lower demand lights because it is VERY long.

light addict....yeah I've got the bug.

Have you tried bypassing the springs?

That can help a lot.
