The switches look great
The reflector looks impressive
But that tail looks like you need to make one hole bigger and one of the guiding rods also, this way the cap only fits one way (or make one rod and hole smaller that’ll do too)
Other version for XHP35 Hi + SMO reflector ?
Oh wait you will want to use same size rods and drill for the holes
OK now the holes are at 9 and 3 o’clock position (straight line through middle)
Do them at 3 and 6 o’clock or any position they are at angle of 90° if connected with an imaginary lone through the middle
Same drill for holes, same rods but only 1 way to close the cap.
Hi Miller
Thank you for pointing it out. One hole bigger and one hole smaller will be a perfect solution
We planned to print “+” “-” marks to the batteries.One-way fitting makes it better. 
Why is TURBO HIDDEN?? Maybe Strobe,but Turbo should be instant access!!
Double-click at any time is hardly hidden IMO
I did not see that! All I saw was Turbo and Strobe were in hidden mode and not the normal sequence. I did not read the whole page!
The Cooling fins in this light can deal with the heat very well , at 6.5A turbo the host got hot very slow.
Electrical-engineer will rise the drain up to 7.5A on turbo.
Turbo date updated in the OP.
Holiday time from tomorrow here. Will keep updating the testing results next Monday when all custom-made components are back.
Or add a 3rd pin to it to make it even easier to line up visually.
Please put a generous radius on those pins. I wouldn’t go for a full radius though because that would allow the tip of the fat pin to fit partially into the small hole.
HaikeLite: Actually you only need 1 pin. The contact PCB will align itself when you turn the tailcap.
Also take a look at JETBEAM sra40, the pin and receiver hole are shaped so alignment is super easy.
I still don’t think turbo is in the normal sequence. Description says low, medium, high.
Turbo is double click. The ui would be so much better if turbo is in the sequence and so that it can be a mode that can be memorized.
I agree - turbo in the sequence is better. In Narsil, I have quick access from OFF to last mode, moon mode, and max/turbo (click, click&hold, double-click) -- what could be easier on a single e-switch? Everyone gets what they want. I normally prefer no mode memory with e-switch's, but when you have easy access to all 3 possibilities, why not?
A bunch of stock lights now have 2 of the 3 features - not sure if any do all 3.
The light looks awesome.
Very entertaining thread. 
couldn’t have said it any better.
thats what i was trying to tell their company….be unique and stand out from all the rest, put turbo in the sequence so that it can be memorized.
the ui they have now, is similiar to olight, nitecore, thrunite, sunwayman, etc…
this way the user has many options….
price range ?
According to HaikeLite it’s “reasonable”…
Highest I would go would be 75
Is there anybody who is good at doing video reviews?
