Hello! I bought a flashlight Olight SR-90 measured and true values ​​are:
Hi position 7.22A
Low position 1.62A
We modified the current growing flashlight:
Hi position 8.38A
Low position 1.88A
modification consists of attaching parallel the "R sens", other 4 resistant 0.10ohmi.After the change feels a clear difference
0.10ohm resistances can be seen in one picture

Good skills and brave work. I wonder if the regulation is still so flat after the mod?
Your pictures illustrate the great heatsinking in the SR90.
This is sometimes overlooked in the demand to make lights of this power smaller.

So that's what my SR90 looks like inside. I am not brave enough to take mine apart, at least not until I have too. I am still concerned that one day I will break the glass lens, until then it shall stay in one piece but I am grateful for the "inside" pic's
Thanks

Hello fellow forum members and SR-90 owners; I've been very impressed from the reviews and posts I've read about the SR-90 and am really considering getting one myself. Couple of questions I could not find the answers to here are:
1)Does anyone know if the charger allows for 220V as well or just 110V-in case I might travel with my light overseas?

2)What is the charging time once the battery pack is completelly drained? How many charge cycles can these batteries take before you need to replace them, say compared to the 1000 cycles on Eneloops?

3) Has anyone traveled w/ this by plane internationally or at all? Would I encounter any problems at airport security taking the light and case as a carry-on or is this something that I'd be better off with in checked baggage because of its size and raw power?

I'd appreciate any sort of imput from anyone with some ideas before making the final buy decision.

Thanks

It charges fine in the UK (240V mains)

I don't know the answers to 2) and 3) but I'd love to see the expressions of the guys checking the hand luggage if you try to take one of those through.

:) I would love to see that look too, but hope it wouldn't be one of impending confiscation

The charger is rate for 100-240V on all the Olight SR-series lights that use the common handle/battery pack, so you should be fine with simply a plug connector adapter (thanks for the direct confirmation easilyled).

Charging current is rated at ~0.5A on the charger, but I have not directly measured it. My SR90 took about 4.5 hours to fully charge from a depleted state.

Not sure how many recharge cycles you can expect, but it's probably comparable to other Li-ion devices. Check out the battery/electronics subforum here at CPF for more info.

No idea about taking it on a plane, but I could imagine you might have some issues ...

Selfbuilt, nice review. As others have said, that took many many hours to get all the shots, format, organize, and present all aspects. It would be nice if there was a 2000+ L output LED that had minimal spill. The problem with any of the big lights is that most of them ignore the spill issue (with dust, ground, foliage reflection, etc.) wiping out your eye's ability to see the farther thrown objects.

The real question on the battery pack comes down to which specific cells they used. If the 6 cell pack is putting out 7.2V @8A, the 2s3p can use "less expensive" cells to cover the output needs. For the price (including the separate $150 list price of separate battery pack), I think consumers deserve to know exactly which cells (brand and chemistry) are being used in a hand held device, including full details on the PCB circuit (balancing, discharge/overcharge protection, current limit, dead short protection, etc.). This is important (chemistry) so consumers can take proper care of the pack, and know what they are paying for.

If I ever get a "serious" light, if not disclosed, I would take the pack apart and publicly disclose what cells are being used. For example, I give XeRay credit for using Samsung 18650 cells in their Barnburner HID.

Have you ever dismantled the battery pack to see what kind of cells are used?

Great work on the head, thanks for sharing this. Looks like some good quality construction in there.

Thanks, these reviews are indeed a lot of work to pull together. :sweat:

Incidentally, I am currently working on a review of the SR92 (3x XM-L U2) and Surefire UB3T, and will compare both to the SR90. As you might expect, the SR92 has a somewhat floodier beam (but still excellent throw), so it may be more suitable for those wanting extra spill.

I'm not sure how many need a more focused light, but you are right that there are few options. The UB3T may be your best bet, as it uses a TIR for a very focused beam with minimal sidespill. Of course, it is a single XM-L, so it is only rated for 800 lumen max. Still, it has impressive throw for that output, with a narrow beam (given the optic). :whistle:

Both lights are in testing now, so I hope to to have reviews up within the next two weeks.

:wave:

Yeah, one of the ? mods ? Bernie (bad memory, but it was a long time CPF member) told me to try the E2D Defender a while back with that TIR, and I was quite surprised at the result. I'll check that UB3T since you mentioned it.

Hi people, can someone in the know tell me if the battery pack has balance charging?

Not sure if they balance charge. I have emailed Olight looking for some info on the pack.

One other thing that I always think about the SR90, which can often get overlooked when I read people talking about it, is the neatness of the beam.

That huge reflector not only gives throw, but really well defined hot spot and spill area, with pretty sharp edges. No messy fussy overlapping beam here.

yes, appears that everyone concerned have no idea as to what i am talking about or they just choose to live in hope that the average user will either loose the flashlight or loose interest in it so that down the track battery pack condition is not an issue. However, as i am the driver of my fate or destiny, and not the passenger, i have opened the pack and things are under my control again. Gotta like that:)

I recently bought this light for seeing animals and people on my property. It's very impressive. It's 250 yards, measured by GPS, from my front yard to the woods at the back corner of my property. This light has no problem putting serious illumination on objects at that distance. I just ran it for 15+ mins straight on high, heat sink barely got warm, and no noticeable change in output.
