Most folks find the usable limit of throw to be about 1/2 to 1/3 the rated limit. I fall into the 1/3 category.
So if I need to see 500 meters, I get a light rated at 1500 meters.
If I buy a light rated at 600 meters, I know I can probably see well out to 200 meters.
These are all rough guides and throw ratings for lights aren’t always correct.
Tom, your using a 1 to 10 ratio? You might be losing some of your night vision or maybe you just really prefer to light things up brightly.

No, I'm just mak'n this stuff up.
I have an acebeam L30 rated 370m+… barely lights up anything decently at 50m range. Totally depends on the individual’s output perception of course, some folks are ok with a 200lm edc.
Everyone should learn what they find acceptable. I’m okay with 1/3 the rated distance. I’ve heard some folks say they are okay with 1/2 the rated distance, but that seems about the limit.
if the GT4 uses removable 21700 size cells and optional short tube, this light would be perfect!
Any update on this light?
Gotta say, I’m stunned at the silence on the status of this project. Figured more people would be chomping at the bit to know what’s going on with it.
Well, we’re no strangers to “long silence” on project threads. It happens sometimes. The FW3A burned a lot of us out from “chomping at the bit to know what’s going on with it.” But other projects have had long silences too, at times. Hopefully, we get some good news on this one soon. 
i hear its "a few weeks" until we get news ;)
Yeah, 4 1/2 months is nothing. The FW3A was 2yrs, and the BLF lantern is going on 3 1/2yrs.
Look on the bright side (pun intended), you’ve got time to accumulate funds to buy it and, if needed, time to find someplace to hide it from your wife.
Neal has a new (final) prototype...
where is the photo?

whats the price range on this? probably out of my limits but curious… and that thing looks insane big
If I may guess (without having inside knowledge of price): 400 dollar.
If it’s really $400… Suddenly the other monster lights from acebeam and imalent with several more emitters, integrated battery charging and massive power handling boost drivers don’t seem that expensive.
Other than very nice form factor for great thermals I don’t see anything revolutionary that makes it worthy of such price tag, I really hope it gets close to the GT’s price, 3 more emitters in exchange of a huge reflector, should be a fair trade.
wow thats almost too expensive and this is without batteries i asume?, compared to olights and acebeams, but ok it will probably have super good passive cooling.
Looks like the handle has a design flaw, your hand placed right over the roasting hot head.
