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

[overdog]

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:

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

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?

Great mode :twothumbs.

How does the switch handle the the current?

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?

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

 

[overdog]

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

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.

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?
