Thats why i want the finns to be ~2mm thick and 2,5-3mm space in between. This is ok aslong we are not having ultralong finns (15-20mm or so). The longest finns on the GT will be abot 5-7mm deep. So no problem with convection!
I have one question. If i understand it right the light will be having threads at 3 points (the green marked lines). Please correct me if i am wrong
Nope, more threads on top for the bezel to secure the lens and reflector. Unless the reflector is going to be threaded in from inside, or a retaining ring will hold it in. Either way, still gotta have an opening large enough to fit the 120mm reflector down into the head.
I may be fluid, but not a fluid as in liquid.
Stuff has 3 phases: Solid, liquid, gas (and plasma too, but that’s unusual).
Maybe it’s a language thing though.
Nobody mentioned “liquid”.
“Fluid” was the operative word.
In physics, a fluid is a substance that continually deforms (flows) under an applied shear stress. Fluids are a subset of the phases of matter and include liquids, gases, plasmas and, to some extent, plastic solids. Fluids can be defined as substances that have zero shear modulus or in simpler terms a fluid is a substance which cannot resist any shear force applied to it.
I don't understand. Only one, actual, specific, real reflector has been proposed. It looks nothing like the renderiings. I hope that other reflectors that perform even better, step forward. But until then, the renderings look nothing like this either internally or externally, 120mm deep:
We also have not found a manufacture yet, till then we can’t make any further progress on reflector options as we do not know what the possible options are.
Ha, Ha. Only one real reflector has come forward in all this time so far. Seems like imaginary, fantastical renderings come first. Really. Please render one with this reflector and then vote on box verses plunger.
EDIT: And, shouldn't the specs come first and then a manufacturer that is willing to meet them?
I was talking from this point the next step is a manufacture.
The specs were more or less set before we started this thread.
The render was the most important thing for finding a manufacture, it vastly improves are ability to communicate what we want.
Now we need to find a manufacture.
After that we can see what options the manufacture has for reflectors and what options they are open to. From that point we will know what reflectors are options and which are not.
It is more like begging and pleading with one of them to take on this project at our price point and the quality we demand. There are not exactly a large pool of manufactures that could handle this project.
The best way to define specs with a language barrier is with pictures, pictures are worth a thousand words as they say.
Thus the render is by far the best way to show them what we want.
Technical specs are not all that complicated, XHP35 LED @ 2.5A+ with a ~120mm reflector, 8x 18650 battery tube with 2x cell carriers and our in house designed driver.
Those specs are easy and were mentioned in the very first post.
The look and feel of the light is what took over 8 months to nail down in the Q8 project going back and forth with Thorfire. We have already cut that down to a mere month to get a design we like and that should vastly improve the rest of the process.
