Please add me to the list with issues : I ordered 2 GTs, short tube, bag, shoulder strap and 2 cover caps. Received everything except one cap ( received one cap instead of two ).
No big issue, no complain ( ), I already sent an email to Neal asking if he could ship another cap with the snail mail.
The GT measures a bit less at the further distance. Interesting.
Crees emitter bins have a tolerance of 14. So you can have the exact same bin and at 2000 lumen 14 would be 280 lumen.
So you could measure one D4 1A at 1860 lumen and another D4 1A at 2140 lumen. This is the outer limits of their tolerance, but still in spec.
Emitter tolerances might be playing a small role in the different lux readings, another would be the little bit of extra amperage the MF04S is giving. I think 0.2A (2.5A vs 2.7A)
I think the MF04 reflector is just a couple mm bigger, not much at all. Maybe that is also a very small factor.
IIRC the MF04 was around 10mm larger, which is fairly significant. They might also be using an E2 bin emitter.
Plus I have noticed that XHP35’s vary widely in performance compared to many other cree LED’s. They really seem to stress the tolerance limits of the bin more then most.
Yes indeed I use Samsung Q30 and also Sony VTC6 batteries for my flashlights. I did use these batteries in both flashlights. Did test over different distances. For me the Astrolux is the better thrower.
Because it measures turbo a tiny bit higher? You can’t even see that difference with your eyes. I would have to evaluate both lights as a whole and on many other factors to say which is better overall.
There are a lot of high drain cells that are all pretty close to each other. If you look a HJK’s comparator you see the VTC6 and 30Q are pretty much the same, even at 15A.
For heavy loads it seems the general rule is you want the less voltage drop for the particular load you are running to get the most power.
FET drivers are a bit unique because turbo is direct drive. So you really need to match the battery to the emitters voltage characteristics. A VTC6 might burn up the certain led, while a 35E high capacity might not. So you have to get the right combo.
None of this info is going through me or TA. Lumintop (maybe Neal) should be contacting the people directly to sort out the issues.
Although… I did ask everyone on the Issues list if they heard from Lumintop or Neal last week. I have not from 3 people, yet. Here is the results so far:
sp5it - no contact from LT
zelee - no contact from LT
FreeMagenta - ???
Bruno28 - no contact from LT
VRT - ???
Tete - no contact from LT
Jimmy007 - no contact from LT
k125bw - no contact from LT
Dustynell - ???
Chito - Neal contacted him on the 8th, but instead of trying to send replacement parts, he offered a $10 refund. That is not a proper solution to a light damaged in shipping (registered box).
Maliblue recieved his missing light so I removed him from the list.
Leo at Lumintop is supposed to be handling these issues, but he did not contact anyone on the Issues list last week.
Here are Sp5it’s pics from the old thread dated March 6.
If this were my light, I would file, bend or cut away the metal lip so I could at least screw the battery tube in while I’m waiting on a replacement part to fix it. It must suck not being able to try it out.
Yep… there is no doubt these people are way past due getting taken care of!!
But I’m like you Jason, I would have done whatever it took to use my GT during the wait…… A little bending, prying, and/or cutting…… that bad boy would have been shining.
I finally got around to measuring the lumen value of my GT, and it’s only coming in at around 1400 lumen, repeated. I’ve so far double checked the batteries, and compared some other lights, which measured as expected, such as a TN42 that measured at 1850 lumen.
