The cup shape makes it much stronger than just a cylinder type shade. i did test that shint base reflector idea originally, and the flat-white surface increases light reflection and reduces the hard-light glare and bad light distribution flaws of most factory lanterns i tested & used. (shiny or chromed reflectors cause to much glare & artifacts.
The cross section can;t really show it, but the shade would definitely need either one or two index locking notches at the head area to lock it from turning. (Same goes for the base)
added! number 849 on the list.
That tint ramping is definitely in line to be added, as this cross section is just the design of this prototype being tested. All it would need is the change to six emitters, ( three 3000K & three 4000K LEDs) and the addition of a third wire lead from the driver.
Thanks for mentioning that to remind me i missed adding that to the drawing. 
i did forget to add the upper rubber gasket/o-ring to the head & the small o-ring to the center bolt. (next updated drawing will have those)
Could you please put me on the list for one light.
Thank You
This really is coming along nicely :+1:
Is the tint range finalised at 3000K to 4000K?
I was rather hoping for 3000K to 5000K, because that would cover everything I ever do with artificial light, from reading at night to workshop stuff, respectively.
I understand that LEDs aren’t always available with high CRI at the cooler colour temperatures, though, so no worries if that’s the case. High CRI is more important to me here 
That is not the problem though.
We can get 90CRI LH351D in 5000k.
I actually ordered some. The problem? They are going to take 6 weeks to lead time.
Ditto on that. 3000 to 5000 would keep far more people happy than 3000 to 4000, without losing anything or costing more I suspect. Look at the reports on the Zanflare T1 that have come in recently, thus far there seems to be a preference for the two extremes rather than for a level in between by those who have been playing with them.
check. just a note to VOB, you also are 620 on the interest list for 2 lanterns total
double check, numbers 850 and 851 on the interest list
check for arisdes as number 852 on the interest list
Got it, your second one is number 853 on the interest list
asciiphil you are number 854 on the interest list
junglejim13660 is number 855 on the interest list
interest list sorted by entry number
interest list sorted by user names
All caught up for now.
@Zulumoose, that is easily done. There have already been tests of the 5000k LH351D, so just asking Thorfire to put in 3xLH351D 5000k 90CRI and 3xLH351D 3000k 90CRI is really easy.
The reason we considered only 3000k and 4000k options were because DBSar did not test them.
If i had some LH351 high CRI 5000K LEDs i would test those too. Right now i am testing the 3000K & 4000K because i have these, and modifying the V1 to use four of the 3000K LEDs to be able to do a direct comparison to the 4000K variants while on my trip.
Interested in one.
Put me down for 1 if I am not already on the list
No problem - if there’s one thing I’ve learned through work it’s how to point out missing things on drawings. Let me know if you need help or a more detailed cross-section for Thorfire.
Btw DigiKey has the 2700K and 5000K 90CRI immediately available so not sure why it was mentioned about 6 week lead time.
About $8 for FedEx international priority which is (1-3 days I think)
you have to use the .ca site
add me for another please.
Thank you
I’m interested, please add me.

Has there been any more interest or discussion on the reflector/deflector to allow adjustment or partial blocking of the output from something other than full time 360 degrees?
My thoughts were that it could snap into grooves at the top heatsink and bottom base plate in order to rotate or be quickly removed.
It would not only block light from selected areas of the 360 pie, but reflect blocked light (white front side black back side) back to lighted areas possibly allowing lower settings to be used for more efficiency. Less output and energy would be wasted if directed only to areas where it is needed and not to unwanted areas.
I have made makeshift shields in the past to block light from shining in certain peoples faces or tents and motorhomes with sleeping people etc. For me, having this all available in a well designed manner on this lantern would be the cats meow. There seems to be occasions where I don’t want or need a full 360 degrees of dispersion whether being carried or hung stationary. 180-270 degrees gets the most use from me.
5000K seems on the cold side for a lantern. I’d think 4000K would be better, or perhaps two 3000K + two 4000K LEDs if they mix reasonably well and don’t end up with color casts that shift over angle.
