Lumintop GT4

I know I could just re-flow them but I live in Canada and it’s very hard to find dealers who carry these high tint/cri bins that ship here

You can get the 4000K 80CRI XHP70.2 from Arrow for under $6.50 per LED with free shipping, but they are the lowest M4 flux bin – XHP70B-00-0000-0D0HM440G.

Kaidomain also sell the 4000K 80CRI XHP70.2. They have a photo of the product label that reads XHP70B-0-5A0-N20-D0-H-01. Not sure which bin that correlates to on Cree’s data sheet. Not sure if that’s still the exact bin they’re selling either, considering the seal date in the photo is November 2017.

@California_Prepper

Any ideas if this light will come in a nice case or a cardboard box?

I would say almost certainly it will be a cardboard box. Maybe there will be an optional carry bag like the original GT. But cases are not cheap, so would likely drive the price up too high.

I’ve been debating purchasing the MT09R. I just realized that you’re the only person with a GT4 and obviously have many MT09R to compare it to.

If you’re considering the MT09R, I would also recommend looking at the AceBeam X45, which has a boost driver resulting in stable output as the batteries drain. The MT09R, on the other hand, uses a FET driver and output drops as the batteries drain. You can get the X45 from hkequipment.net for even cheaper than the MT09R if you exclude the value of the batteries included.

@TexasAce I’ve been debating purchasing the MT09R. I just realized that you’re the only person with a GT4 and obviously have many MT09R to compare it to. Obviously runtime is completely different but lumens I’m assuming are similar? I’m curious just how much larger the hotspot is on the GT4 and if you notice a serious difference between the MT09R and the GT4? I’m aware the MT09R only has like 650m throw and the GT4 has 1500m (or so) but in the real world those numbers don’t matter much beyond 300-500m. I night hike and some of the biggest clearings I find are only 600m long. So for instance, at the creek you take beamshots at or in your testing just how different are the two?

Not sure if you realize it, but the rated distances on flashlights is to moonlight level light, and that isn't very bright. So, using a 1000m rated light for 100m targets is get'n close to daylight - nicely lit up, but using a 300m rated light at the same 100m target will be little brighter than moonlight, maybe sunset level.

For me, I'd like to use the 1000m rated light for 100m targets so I can actually see them, but I'm an ol' guy...

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.

[JasonWW]

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!

[mgracia85]

Any update on this light?

[Coyotehawk]

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.

[DavidEF]

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.

[M4D_M4X]

i hear its "a few weeks" until we get news ;)

[RobertB]

Yeah, 4 1/2 months is nothing. The FW3A was 2yrs, and the BLF lantern is going on 3 1/2yrs.

[Gj1 (Gj)]

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.

[M4D_M4X]

Neal has a new (final) prototype...

[Theodore41]

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.

[will34]

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.
