It’s the first time in my life when I see a pleading for theft publicly committed by a person. Using your logic you can say for example that a crime is virtuous because the victim gets to a better place, without the everyday problems .
Perhaps it does not make sense to do any homework anymore, copies from colleagues and ready. But still … if everyone goes on this principle, it will come to a given memento that everyone will expect to copy from the other and will do nothing. But then who else will it be? Perhaps innovation in stealing technique.
I have not heard anyone in the EU encourage the theft.
If we look at the obvious simplistic problem that all flashlights have a battery, a driver, a reflector and a light bulb or led. Everything put into a casing. Evidend no one brings anything new. Not even BLF GT. You can not find the wheel again.
However, to come up on this forum say that BLF GT does not bring anything new I find something unthinkable. I’ve dreamed it like a flashlight for years. Why has not Astrolux done so far? Why exactly now? How do they have similar performance? I bet the reflector, the most important and laborious part to which GT has worked and tested and tested again simulations over simulations, is the same. How can you say GT has not brought anything new !!! ??? It’s crazy to say that!
Astrolux does not bring anything new. Perhaps only a weaker and cheaper copy.
Very good. She will find her place in many collections. But it’s just a copy.
While the BLF GT is a road opener !!! She opened a new era. It passed the 1M cd bar at an acceptable price !!!
And on the other hand, it does not seem right for you to make such claims that GT did not bring anything new. A little respect for the work of such enthusiastic people would not hurt you.
I have read many times what you have written and it seems hallucinatory. Copying is a virtue!
I mean, if I copy one of William Shakespeare’s works and assume it’s mine is that I’m a virtuoso?
Not even in Chinese culture copying is a virtue. It’s just tolerated for economic reasons. Do not confuse efficiency and effectiveness with virtue.
Produce at a lower cost. And obviously the easiest way is to get a ready-made product and copy it. Modify something around here is not exactly the same and the development cost is zero. As you said, the guests have to win. A similar product at low cost.
But my first post was just that. Do we encourage such behavior? We decide whether or not we tolerate such behavior. What means do we have? For example, could we buy this product or not?
Let’s end here, it’s a big offtopic.
I meant precisely what I said, that copying is a virtue.
And, BTW, Shakespeare would agree - he copied a lot.
ADDED:
BTW, I do respect the GT creators.
Okay, boss. Copying is indeed a virtue but for the copied one. I think that’s what you really meant.
Perhaps Shakespeare would have bought Astrolux and not BLF GT. It’s a matter of taste. All the best
We already know there is no benefit to making the reflector deeper.
You can’t push the current any higher. The xhp35 just can’t handle it. Even other top throwers, like the TN42, only use 2.25A. Anything above 2.5A just creates more heat and no real increase in brightness. (Maybe you can get 100 more lumens?)
I’m pushing my XHP35HD E4 that I de-domed to 3amps in my BLF GT. and in my TN42’s.
Is it an extra 125 lumen?
Is that worth the extra heat and battery drain?
To change the subject slightly, have you tried out a sliced xhp50.2 in a big thrower? It’s a little bigger die size compared to the xhp35-HI (2.35mm2 x 2.94mm2), but about double the lumens.
It’s about the same die size as the cft90, but a bit less output. Since the cft90 is doing about 1.5mcd in the GT, I wonder if the sliced 50.2 would do about the same as the xhp35-HI (1.2mcd), just with a bigger hot spot. The GT’s driver could be still be used, you’d just have to resistor mod it to about 6A at 12v.
looklike it’s the limit of 3535 package right now, there is no way to pass that
led wait for xhp35.2
That’s strictly incorrect. What was determined is that it’s a good size to performance tradeoff, not that deepening it doesn’t help.
- Deeper reflectors have smaller centre opening and therefore more area, so they throw better. Not much though.
- They collect more light into the beam making it wider while narrowing the spill. We’ve seen complaints that the spill is blinding, so that may bring some improvement.
Two of my interventions have been marked as rude. I want to know what the reason is.Truth is rude? Thank you
Hi Tom, do not think too much of getting a few rude marks, ignore them and in a few days you are back to zero . Every time someone writes posts that disagrees with someone else, all of a sudden rude marks appear, I had that happen too. Although in the forum rules it is explained very well what he button is for and explicitly what it is not for, some people misuse the button if they just do not like an opinion. Our administrator in the end decides what to do with posts and people who are marked rude and he will sort out what is really going on. Still the button has proven to be very useful for the administrator in signalling bad behaviour on the forum so he can act upon it, so overal the system works well.
The E4 bin XHP35 that’s been de-domed hasn’t been tested for Lumen output that I can find. But my GT with the de-domed E4 at 2.5 amps and 3amps shows more throw than the other stock GT that I had (before changing it into a Lumen Monster XHP70.2)) with what ever binned LED was in the Stock GT and more throw than the E2-3A HI I had in it at 2.5amps. Nobody else has one like it, so it’s worth it to me, and that’s all that matters 
I bet it will smoke your stock GT! :sunglasses:
I think your technically correct.”
The best kind of correct.
This is an example of depth/diameter ratio vs lux and spill angle
Nice!
And where’s GT?
As I’ve read in this forum that the XHP35 HI E2 can easily (provided excellent heat dissipation/transfer) to 3A, I wouldn’t mind a driver that pushes my BLF GT to that level.
At 2,5A this led might do around 140cd/mm2 and at 3A it will do around 170cd/mm2.
That’s quite a difference.
Easy calculation: @ 2,5A - 1.142.000Cd / 140 = 8157*170 = 1.386.714Cd.
244.000Cd improvement? Yes please.
.
Apart from the heat transfer, the driver would need to be top notch and have an accurate heat sensor, dimming the light at a set temperature.
Suggestion: turbo at 3A, high at 2,25A.

Close enough to a depth/diameter ration of 1, so going deeper will not help throw, it will make the hotspot wider :THUMBS-UP: , the spill narrower :THUMBS-UP: and the flashlight longer 
So well into the diminishing results on intensity, with still small possible improvements to beam width. It would be interesting to also chart light collection into the main beam. I’m sure there are charts somewhere…
The BLF GT driver can do 6A easily (maybe a bit more) with just a resistor swap. So if you want to change it to 3A, you can.
Yep.
A longer reflector will give a tighter hotspot, narrower spill and a larger corona.
Example deep reflector: Thrunite Catapult V2/V6.
Example shallower reflector: Olight M2X.
