Lights in 4000-5000k that can do at least 1.5hr at 700 or more lumens

LED Flashlights – General Info
1

I’m okay with the head being 1.5 inches wide. I’m not a fan of sharpie sized lights, I don’t care about weight either, but do want them to b remotely pocket sized.

I’m already aware of Zebralight sc700, convoy s21d, acebeam e75,e70, sofirn sc33, are there others?

I’m also aware that olight baton 3 pro max can do almost 700 lumens for almost 2 hours.

I’m curious about other lights.

What else?

The big one that I see missing from your list is the Wurkkos TS22.

From 1lumen.com:

From selfbuilt’s review here on BLF:

I’m not sure which graph is correct, but they’re both impressive. They could both be correct, if the ambient temp was vastly different (winter vs summer testing, for example.)

Edit: I forgot to mention the Sofirn SP33S. Another really good light for sustained brightness, at least in high mode and not turbo (as long as you’re OK with it being 26650. Some don’t like the girth.)

IIRC selfbuilt’s one is XHP70.2, 1Lumen one is XHP70.3 HI R9050 5000K. So they are both correct, just different emitters…

Ah, OK. I didn’t realize that the 70.2 and 70.3 were so different from each other (electricly speaking, the tint shift is clearly way worse on the 70.2.)

I think more of the difference lies in the fact the 70.3 is R9050 than it being 70.3 HI

As for lights that meet the requirements, most of the recent Firefly lights do eg. X1L, X1S, X7

Then You have the Convoy M21H and M26D. Probably most Convoys with the XHP70.3 HI 4000K can manage this.

What’s more, I’d guess all Emisars with the new Lume1 driver will manage 750 with the right emitter.

Another example would be Armytek lights with warm white XHP70 (whichever version) and 21700 cell

There are probably plenty more, 750 is not that hard with a decent driver and a 21700 host (or larger ofc)

Based on the runtime charts those emisars can’t seem to hold more than 300 lumens. Even d4sv2.

Has anyone done runtime tests on emisar? I’d like to see charts.

Those all use old drivers, mostly linear. The Lume X1 Is a highly efficient boost, same as in some (most?) newer FFLs.

Sustained brightness almost exclusively depends on the physical size/surface area of the host and the driver. And ofc on LED choice, but that’s a given.

As for the older Emisar lights, I see that the D4K even with the older boost driver manages about 850lm for over 2h with 4500K Nichia 519As. I’d guess getting the same platform but with the new Lume1 driver would bump that result a bit higher still
