"Dark Star" quad SST-90 Elephant II @ 9000 lumens -video added-

Hello,
tonight I had to put some parts together:
-Fivemega´s Elephant II
-Fivemega´s 3X Turbo Head
-Custom made heatsink
-Ledil Lily-S reflectors from PhotonFanatic
-4x SSR-90-W65S-R11-GN-100
-4x AW IMR 18650 cells

All the parts ready to go:




The SSR´s on the heatsink, wired in series:




Everything in it´s place:




Here it is:




Current measured at the tailcap, once I got over 10Ah, but got no pic:

Wow... 9000lm I hope the night come soon.

Re: "Dark Star" quad SST-90 Elephant II @ 9000 lumens

What is the cost of all parts you have used to build the light, in total?

Re: "Dark Star" quad SST-90 Elephant II @ 9000 lumens

Pay attention, you could sizzle your retina while taking those beam shots

I think the OP could make a "cake recipe" for us [all jealous]!

Wow! 9000 lumen AND you were able to convince your Gf/wife to help holding the multimeter probes?

Good spot.

This is insane.

Re: "Dark Star" quad SST-90 Elephant II @ 9000 lumens

nice work ...

Re: "Dark Star" quad SST-90 Elephant II @ 9000 lumens

lol .... Runtime until it ? 2 or 3 minutes? :green:

cheers

Re: "Dark Star" quad SST-90 Elephant II @ 9000 lumens

I was just drooling over the beamshots from the Black Star, and now this... ..subscribed for the darkness

Awesome mod again! :thumbsup:

Re: "Dark Star" quad SST-90 Elephant II @ 9000 lumens

Great mode :twothumbs.

How does the switch handle the the current?

Re: "Dark Star" quad SST-90 Elephant II @ 9000 lumens

Is that 10Ah for the battery with the cells in parallel? But you say the LEDs are in series, direct drive. Wouldn't the battery capacity be about a quarter of that, then?

Re: "Dark Star" quad SST-90 Elephant II @ 9000 lumens

Very sweet light, overdog! We did not see any driver - is this (gasp...) direct drive? Good work! Jeff O.

Re: "Dark Star" quad SST-90 Elephant II @ 9000 lumens

Thank you for nice words!
@ Torchboy and Jeff: this light is direct driven- batteries and emitters in series.
@rayman: switch is little bit modified- too thin electrical leading contacts inside are thikened with solder- sorry, cannot better explain this...

best regards,
Steffen

Re: "Dark Star" quad SST-90 Elephant II @ 9000 lumens

Man, that thing is so bright. . You made us all jealous. :thumbsup:. I wouldn't call it dark star instead i call it shining star.

Re: "Dark Star" quad SST-90 Elephant II @ 9000 lumens

It's nice to see that someone do it and builds a really monster LED light

What kind of betteries do you use?

I would liked to ask you at the Black Star's thread, but I ask you now: so, why don't you use some bigger, deeper and smoother reflectors? A lot of light just go out at the sides, so it's a big waste of power and light...

What's the temperature of this thing? After 5-10 minutes? Anyway, can it go for 5 mins?
