Thanks everyone for the nice comments. Blushing You guys make it fun here at BLF. Thumbs Up
It has been a tough to get time to finish with all our family things going on thru the holidays.
The light is finished but time ran out to add some extra lenses with beam shots, so I will do that later in a separate thread.
Never thought about naming it the …Hulk… ‘G0OSE’, LOL, good one. Cool
.
It has been a nice surprise to see more members join the contest.
I hope next time more will enter and not be afraid or feel unable to build something, we are all here to help each other.
Every entry is important and welcome in many ways, so jump in there and join the fun !

I finished the Skeleton flashlight BUT, there were some things I was going to add, but ran out of time. I should have been more attentive.
.
This addition is AFTER the competition ended and did not get judged.
.
After the contest ended and further inspection and testing, it was noticed the new xhp70.2 was defective, only operating with 2 of 4 diodes.
So I replaced it with a new one and tested with Samsung 30Q batteries.
.
The light was more than twice as bright after fixing it.
.
Just for the record, here is what was planned.
.
.
258,735cd
7200lm
1,017m throw
6v @ 11.2 amps
Transparent body
Active cooled
clear flat AR coated lens
Green lens
Red lens
Aspheric lens
.

Clear AR coated flat lens



.
Green lens was less noticeable on high.




.
Red lens, not very useful.


.
The Aspheric lens was so horrible it was not taken.
Looks impressive on the light, that is all, LOL. Wink

My favorite element of this light is the turbine heatsink combined with the clear body (so you can see it). How does it handle the heat in use on a turbo run?

It seemed to do real good.
The heat can be felt coming out the exhaust holes, the fan could be stronger, maybe I will bump it up to 6v.
I will do a heat test today and post some numbers for you. Wink

After this test, it was noticed the Turbo Timer was pre-set at 120 seconds from Mtn Electronics.
This driver was initially purchased for a small light. Facepalm
So I threw together some available parts and ordered a bigger reflector and lens for this project and did not remember the specs on the driver. There was time to order another one too. Silly
.
At turn on + 30 sec. 10 amps, 7112 lumens, 22c at the led base.



.
After 2 minutes 9.67 amps, 5600 lumens, 30c, the thermal step down started after 2 minutes and continued until it was off completely.



.
In conclusion, the temp had stabilized prior to the 120 seconds Turbo Timer cutoff. Beer
It runs cooler and does not cut off at lower setting. Beer
I wish a longer Turbo test was possible. Tired
