All cells fully charged.

The beamshots were taken from my porch, as you can see it's snowing lightly which reduced throw. I aimed the lights down the driveway at the road running left to right in the distance.

In the foreground the small tree at center is at 35', and the far bank of the pond to the right at 80'.
To the downhill left bend of the drive it's 200', the road is 350', and across the road is a grove of trees at 450' of which some trunks are visible.

In all the pics you can see the edge of the beam except for Trinity; her beam's too wide to capture with the focal length of 18mm. The small tree to the very right at 10' gives a good indication of beam width and spill.

I'd like to thank to MJ and Mac for their help with parts and expertice, and DFiorentino for planting the seed in my head.

EDIT: Shark micro sink installation

While waiting for LuxLuthor's pack, I've been testing the light running on the 18 AA, 10.8 V holder. I found that due to thermal issues the Sharks were shutting down after 1 1/2 minutes on hi.

The Sharks were getting hot due to the level of boost (to be somewhat alleviated by the 14.8 V pack being built), and due to the total power running through them. Wayne recommends 15 Watts max in the stock configuration, and these are pushing over 25 Watts each.

I disassembled the light and fabricated two micro sinks for the top of each Shark from brass shapes and Romex core. The box sink with the soldered Romex epoxies to the top of the IC, and the bent leg sink to the top of the diode. Both create thermal mass and a path to the tube.



After reassembly, I tested the light running off my power supply at 16 V, 4.8 A, and after four minutes the head got very hot, but the Sharks were still happy. I reinstalled the partially depleted 18 AA holder and ran for 5 minutes, the last of which the cells couldn't keep up and the Sharks were flickering, straining to maintain the increasing level of boost. Again the head got hot, but the Sharks were still going strong.

:faint: :drool::bow::wow:

Words fail me when I look at these masterful lights of yours Dennis.

Yet another fantastic creation.

I guess it must be outputting about 3000 - 3500 lumens at max?

What is the beam like with the narrow Fraens?

Does it project far or is it floody?

Thanks easilyled.

The beam is still floody even with the narrow Fraens.

It doesn't throw as well as the 9 Cree MD, but the beam is much wider with brighter spill. Definitely brighter than the Cree MD, and your guess about lumen output is as good as mine. It has a nice white tint too, makes the Crees look more green.

Once I receive the Emoli pack from LuxLuthor, I'll take some beamshots. The 18 AA holder is temporary, and the Sharks don't have any headroom. The Sharks throttle back the last 1/4 turn of the pot running on the AAs.

Re: Moby **** Trinity (3 X Ostar, 3 X Cree, 3 X Shark)

wow, thats a very beautiful flashlight !

waiting for some beamshots and compares :popcorn:

i think this light will get very hot under fully brightness - 25V*0,930mA=23,25 * 3 = 69,75 Watts :eek:

my BigMag³ runs at near conditions: 3,7 volt@ 20Amperes = 74 Watts. After 5-10 Minutes @ 100% it will be very hot and you have to dim the light.

I thought the original moby **** was impressive (and it still is) but this shows some serious ingenuity :wow: good work dude.

Thanks guys.

This one is really pushing all aspects of the mod. The cells, the Sharks, the fit, and heatsinking. Using just the (3) Ostars and not the Crees is a bit more rational. Ostars need to have a relatively low Vf of 21V or less when paired with the Cree to stay under the Shark boost ceiling.

wow, thats a very beautiful flashlight !

The light does get hot, but I'm waiting for the battery pack to really give it a workout and take beamshots. It draws nearly 80 Watts so it's pretty demanding on the cells.

Zep,

The Moby **** Trinity is state-of-the-art, you are the cutting edge of multiple LED mods! You set the bar very high, you'll have many CPF'rs following your lead. I can't wait to see all of the other competitors!

Awesome work!

Zep, what exact model number of Fraen narrow beam reflector did you use for the Ostars?

And, the light is beautiful, but the pictures of the machine work that was done for the Crees is even more impressive.

Amazing!

Is there any way to get a shorter setup.4s2P maybe?
