Searching for 7 led, 2000lm+ sustained single 26650 or 26800 compact

Oh, and 2000lm vs 1000lm is visually only about 30% brighter, not twice as bright.

My MF01 mini XPL HI can sustain close to 1000lm. It is fully regulated at this output and also too hot to hold unless the ambient temp is low.

I would be looking at lights like the Wowtac A4 or A5, Sofirn SP33 or Rofis MR70. (The A5 and Rofis will be all flood “wall of light” though). I would think these lights should be fine with 350~450 lumens continuous, on a moving bike with plenty of air cooling.

I like the side-button interface for my commute, Fenix E35UE shown. I run it on HI continually at 350~400 Lumens and have never had an issue with overheating or anything like that. I have ridden it on pack-dirt XC trails (no hills) and its been fine for that. I have never taken it on mountain trails though. I would need a better mount for that, and more lumens wouldn’t hurt.

The other variable is your max stop distance. That should be used to determine how much throw you will need. This will vary from one person to the next. You always want your light to throw farther than you can stop, so you can identify obstacles with sufficient stopping distance.

How many lumens can a soda can light sustain such as a Q8 or SP36? It’s gotta be close. The Sofirn Q8 throws pretty good.

The thrunite TC20 is also a contender… but its going to be all flood like the A5 and MR70.

You should probably update the original post to let people know you are specifically looking for a bike light for night mountain-forest rides. Thats a pretty unique requirement, IMHO.

Good luck though!!

Fireflies E12R is close in some ways but doesn’t meet every requirement you have.

NSx4 can probably do 2000 continuous off a single cell. No anduril though and throw is non existent as far as I know.

Looks like it can do it.

Wow… thats impressive.

The upcoming Fireflies E12R should be as close as it gets. Specs say it can sustain 2,580 lumens for 10 minutes and 1,200 lumens for and absolutely incredible 2.8 hours if it is true. No other light in this size range comes close but these numbers have not been confirmed as the E12R is not released yet.

The MT07/MF01 Mini have a weird heatsinking issue with the driver, resulting in poor sustained performance at the top of their ramp. I think with the mod that fixes its heatsinking, it should be able to sustain as much or more than the E12R. Get 7 6500k XPL2s in there and I think it should be able to sustain quite a lot of lumens.

That NSX4, with its 4 XHP50.2s and massive amount of cooling fins, that seems like the perfect light for this application though.

No way the MT07/MF01 Mini can sustain more than the E12R even with the copper mod. I have 2 of those. The problem is the 7135 driver. The new FF uses a premium grade Lume buck driver so the E12R will be unmatched at least for the time being. Also 12 LEDs will alow it to run more efficiently than 7 LEDs.

The NSX4 is huge. Not going to be anywhere near pocketable. I love the heat fins though.

They’ve fixed the overheating 7135 issue on the MF01 mini. I measured mode 6/7 at 2.35A. It can sustain this until the battery is depleted.

2.35A with 7 emitters on the MT07 vs 6A with 12 emitters on the E12R

The E12R is going to get hot with 6A. My Supfire M6 with 3xXHP50.2 3V is pretty uncomfortable to hold at 6A after awhile, and it’s a much larger light.

We’ll see. Specs say it can maintain 2,580 lumens for 10 minutes before stepping down. Hopefully with driver don’t shed much head given the very high efficiency and also the emitters will be operating in its high efficiency range therefore minimizing heat.

How did you find out that E12R using Lume buck driver? Does this mean loneoceans is making the driver? I do not see where it is listed that the new flashlight is a Lume driver on the website, unless you confirmed with FF or loneoceans? Maybe we can ask what the spec is.

At first I thought the E12R was using the same optic as the ROT66.2, but looking at it again, it looks as though the optics are crammed closer together. Looks to be same diameter as ROT66.2’s head, just larger, throwier optics? It is an interesting light, indeed. XPL2s are so damn efficient, with all 12 being able to run at 1200 lumens for 3 hours.

NSX4 doesn’t seem too much larger than the E12R. It is a little longer, but it never gets wider than 44mm. Seems perfect for jacket pocket carry, even though it is an inch longer.

Fireflies E12R: Very nice looking, can’t find a good review with sustained lumens, but top candidate at the moment. Head diameter 47.6mm
NSX4: i ordered this light a while ago but nothing ever came from nealsgadgets (after months) so i cancelled the order. 2500lm for 47 minutes! Shame it’s so big. 44mm

That’s cause they haven’t shipped yet. Est ship 15th Jan.
