Having a very clear vision on how the projects I am deeply invested in should be done. As open as possible, and this requires the people in the team to act a certain way to make it work. Gently and keeping the high spirit despite negativity some people will bring, make things that could be seen as negative not so, and in a short period fires are put out.

Right now I see two methods being mixed, and causing problems.
This is costing me energy and will not stop since I see now two fundamentally different approaches are making this harder then needed or then the project and BLF deserves, I apologise for not acting on this sooner and taking this step long ago when it became clear my way of doing it does not work in this setting.

 

Brr the horror that people see me as being in charge, there are/were lots of projects being done with people actually in charge and one of the reasons for starting the Q8 the way I did was because I have the vision this is not needed and was very lucky the Q-team as a whole acts in such a way to make it possible to have the enormous positive flow I know BLF to have in many aspects Thumbs Up

 

No disrespect of other ways, they have proven to work fine many times.
Apologies for wasting time and energy trying to get the Q8 flow going here, and not seeing forces are against that.

I can be considered out of the process and will just update the OP and first posts, when team members send me a PM or email with what you want posted and where, I'll do it.

No problem in having different approaches but trying to mix the two proves to be not working fine and that is a shame. It also takes time and energy better spent on other things.

Good luck making this monster a reality Thumbs Up

That was certainly enlightening, thank you. But somehow the one question that was asked went unanswered…….. Sad

Teacher, I’m working with/on that design so at this point it is still in.

To everyone, if you want to have the gt made please drop this discussion.
There is nothing more to say, all important questions are answered and everything you need to know is said.
We will give an update when we have one.

“To everyone, if you want to have the gt made please drop this discussion.”

Amen.
Drop the drama and if need be, let the moderaters filter it out.
Let’s stick to the subject and move on.

I’m still in!

Err.. drop the conversation??
What’s going on here? I’m totally lost. There has been literally 90% less banter on here for the last 2 weeks, than anytime before.
I’m getting the impression something is going on certain members don’t want us to know about. If the conversation is to be “dropped” why even start a GT thread?
This is BS. All the drama is over, we want answers and updates and now we are being told to not discuss anything?? Bollocks. 100%.

This is exactly what I ment with ‘drop it’. There is nothing “going on”.

Obviously I was referring to all the drama. Its perfectly fine to talk about the GT. (might be better if I’ve said drop the drama)
All that need to be said from the team is said. There are no updates at this point afaik, all the questions are answered.

I don’t understand how it can be so extremely cheap? Even the smaller ones listed there are more expensive!

So,if there is a order of some hundreds of 120mm mirrors,the asked price would be a bit more expensive and not way expensive.

It looks like instead of machining the reflector they use a technical procedure called deep drawing. Once you have the form the production is be very cheap. My guess is that these reflectors are used in those cheap handheld plastic led “searchlights” where they sell high quantities.

So, if your “guess” is correct fritz15; do you think this type of reflector would be suitable for the “GT”?? Or would it just be a cheap compromise that sacrificed preformance?
Any thoughts or guesses at this point?

My guess there is that there is a reason most or basically all flashlights known to me use a reflector which is turned on a lathe. But I really don’t know very much about that so I’m probably the wrong one to ask.

Thank you, I understand; that makes sense to me.
I can’t imagine a reflector priced that cheap having much real value except for use in a crappy light.
But hey, I could be wrong; I’m no highly trained expert either. Wink

I’m going to guess that it will work with large LEDs, but not will really small ones like XP-G2.

Why??

The bigger led, the more light will be reflected in the “wrong” direction..
But whit a smaller led placed exactly in focalpoint, more lightbeams will go in the right direction for that specific reflector.
And with a mathematical perfect parabola reflector with relatively big measures, the accuracy of installing the led in the focalpoint will determine if it will send the lightbeams in the right direction.

So a smaller led (if we can imagine they have the same output) will be better in this case.

Probably what The_Driver was implying is exactly what you said. Since there is a lower expectation for collimating the beam of a larger LED, the lack of surface quality will be less noticeable than with a smaller LED.

Reason is not automatic. Those who deny it cannot be conquered by it. Do not count on them. Leave them alone.

I do hope, and I belive we all know, this flashlight needs e good reflector…so please don’t use a low-quality reflector in this build.. Facepalm

In my mind we have to build this flashlight around a pretty high-end reflector..and have the china’s to make the housing for us.
The led we have chosen will do our job, that I’m sure of. Thumbs Up

Then we will (maybe) reach our goal of +-100$ price..maybe.

But what do I know about this.. Wink

(DavidEF and the_driver, I hope we don’t need a bigger led to make up for a low-quality reflector.. Wink )

So a smaller led (if we can imagine they have the same output) will be better in this case.

I said this based my knowledge of spotlights and the experiences from multiple modders, notably Vinz. If the parabola shape of a reflector is not accurate it is impossible to get a small light source in the optimal focus point so that the entire reflector surface is lit up uniformely (which is needed for maximal throw and efficiency). This is why HID spotlights (those with short-arc bulbs) like the Maxabeam (and even the Polarions and XeVisions) use high-precision electroformed reflectors (larger ones cost multiple hundreds of dollars). Short-Arc bulbs have very small arcs (<10mm) and in these arcs most have a very small, much more intense part of the arc. The 75W Xenon bulb of the Maxbeam for example has a 0.3mm hotspot in the arc. The reflector needs to be precise enough to be lit up completely by this small hotspot in the arc if you want maximum throw.
Now, with LEDs this is much easier because they are much larger than the hotspots in the arcs of short-arc bulbs. The XP-G2 for example has a size of 1.6mm^2 to 2mm^2 (depending on how old it is) when de-domed. The XP-L HI with 3.67mm^2 and XHP-35 HI with 5.9mm^2 are already much larger. Still though the XP-G2 (de-domed) and smaller LEDs like the XP-E2 and Osram Black Flat are much smaller than the XHP-35 HI.

Mostly problems arise when large plastic reflectors are used like the one in the Fenix TK-61. I have read a post of someone who had problems getting a de-domed XP-G2 into focus. The XP-L HI worked though.

EDIT: here is a nice example of what I wrote. There are 6 different HID spotlights which all have large reflectors of varying quality. You can ignore the size and actual brightness of each reflector. Just look at how uniformely bright each one is. The last two lights have high-quality reflectors. The Polarion (second from the right) has a electroformed reflector and the light on the right has a glass reflector.
A note regarding the Polarion: because of the position of the light in the picture, the arc was not straight. This causes part of the reflector to be darker in the picture. LED lights don’t have these problems.

EDIT2: this might be interesting for some people here – the brightness of the reflectors in the pictures shows the luminance (“surface brightness”) of the different lightsources. All of the lights except for the last one (last two pictures) have standard automotive HID bulbs. You can see that they are very similar, but the Polarion and the Vector are better because they overdrive the bulbs. The last light has a 120W Philips UHP (ultra high pressure) mercury short arc bulb used in projectors. They have an extremely high luminance. Even though it has a slightly smaller reflector than the Polarion it produces more than 5 times the Candela/Lux. Candela is the product of reflector size and luminace of the light source.

I was reading our post in the sleep almost.. Wink

But I now see we do agree in specs of a good thrower, and as I said: I hope we can get a pretty high-end reflector in this build.. Wink

I don’t think it will be too much of a concern as long as the reflector is made out of metal and works with the XHP-35 HI. Most people will just use this configuration. You can’t expect a 150$ reflector in a 100$ light Big Smile .

I do think that the reflector should be tested with the XHP-35 before planning continues. Otherwise it makes no sense to design a host specifically for this reflector.

You can have the most precision Reflector in the world, but if you put it in a POS receptacle, like a TK61or a Courui D01 being even one of the worse for example, good Luck tuning it!! So a precision engineered and manufactured receptacle is just as important to match and support this reflector. You think you got it till that last turn of the bezel and it twists or the body shifts on the loose POS threads your precision reflector is thrown off axis or cantered!! Facepalm

The bigger and taller the reflector the easier it is to throw it out! Big Smile

I have heard the complaints of the TN42 costing way to much ( I paid $164.00 shipped DHL ) maybe so, BUT the engineering, design, and manufacturing, machining, the precision is there. I have done numerous mods to it, taken it apart 8-9-10 times maybe, using a de-domed XHP35HD and it went back together perfect every time, and the results were and are repeatable! Try that with a TK61 for a $130.00! Big Smile

Just saying! WinkThumbs Up
