Lumintop GT4

Well, EDC does mean Every Day Carry, right? Search and Rescue is one occupation where a sizeable spotlight could be carried every day. :wink:

lol I agree except for the fact that I have a friend in S&R and 80% of their job is actually in daylight. The majority of what they end up doing is actually running crime scene object of interest searches

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

GT4 would make a great dog walking light. As such - it could be carried every day.
Well, as long as your area is not overly urbanized.

I do not own any large thrower style flashlights. The most powerful flashlight that I own is the BLF Q8.
After seeing the cooling fins, and the design appears to be setup to handle a lot of heat, I am interested in getting one of these.

If there is an interest list on this little lamp, please put me on it.

Thank you

When the list comes out, I’d like to be on it as well for 1 unit.

I too do not have any large style throwers, only some single 18650/26650 throwers and floods. I wonder what my neighbors would think should I use this as my dog walking light? :slight_smile: urban/suburban environment be damned, I’d give it a go for the simple comedy of it!

Been following since the thread inception, any new information on revisions and production release? +1 for the 4000K and highest CRI possible.

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?

Have you seen the XHP35HI MT09R?

Definitely. I really like both the 35 & 70.2

The 35 is an amazing thrower with a very concentrated hot spot while the 70.2 is a good thrower that doesn’t really have a hot spot more of a huge spilly area. lol

I really like the MT09R format for it’s very small size compared to other throwers with similar specs but I’m finding it very hard to decide on which MT09R to buy and if I should even bother considering that I’ll be buying a GT4 whenever it eventually drops anyways

I think you meant smaller. It should be much smaller.

I have both the 35 and 70.2 version. I never use the 35 version because there are plenty of lights out there that perform similarly or better. The R90C is basically a super charged MT09R 35. I think even the Sofirn SP70 should perform the same or better than the 35 version. However the 70.2 version is unique and has a very practical beam that is also super bright.

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.

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.

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.

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.

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?
