Hi guyz, A short while ago I made my dream (which I had for years) reality:
A mercury-arc Cyclops Thor mod:

Playing with Maxabeam for over four years I wanted to create a light that was even more powerfull, not only in lumens output, but in throw as well.

The osram HBO 103/W2 produces 3000 bulb lumens and has the highest possible surface brightness ( exept for lasers ofcource )
Combined with a high quality parabolic Rhodium reflector this gives close to 40 million cp. (measured using calibrated equipment)
It took two months to complete this monster.

Putting 54 NiMh 3300mAh cells together was a difficult job on its own !
The ballast has a 18-36 volt input range so I combined 3 groups of 16 cells to get 19.2 volt at 9.9 Ah, enough for 100 minutes of operation time.

Using mercury-arc comes with a few hazards: It radiates the complete harmful ultra violet spectrum in the book: Toxic ozone generating UV-C included ! So I made shure that the front window blocks all of the UV-C and UV-B and most of the less harmfull UV-A.

The front window also has to protect me against lamp-burst: The lamp has lower than atmospheric pressure when cold, but generates +85 atm's in full operation!
The device is thermal protected and a key-lock prevents accidental ignition, its not a toy!

The lamp is adustable in all directions with a precision of 0.01 mm, nessessary with a arc surface of just over 0.1 of a square mm.

38 million cp's create a spot on clouds up to 4 miles high with ease:

And compared to Maxabeam: see for your selves:

For max throw surface brightness is the most important, the next picture will show the difference in surface brightness of a few lamps: in the middle Maxabeam at high power, at the right the mercury-arc thor and to the left the very faint contours of my HID Thor at 50watt power! The picture was taken using a type 13 welding filter.

So,,, any questions??

WOW!
Where did you get that beautiful reflector?
I dont even dare to ask what it cost you to build this Maxabeam Crusher.

Really impressive!

Thanks pyro,

Yes, it is a quite expensive project: The reflector costs about 800 USD! Its a very high quality reflector used in lab-equipment. The total costs of the materials is about 2000 USD. But it was worth it (in my opinion...)

And to give an impression of the smoothness of the reflector:

BTW, Here Maxablaster runs with a Ushio UXL 75-XE xenon short-arc (With the same specs as the lamp of Maxabeam.)


Regards,

Ra.

Thanks Taylorf,

The led's are for voltage check during operation: low voltage can damage the electronic ballast that operates the lamp. So if the two red ones bigin to light up its advisable to turn off the lamp!

Hi Ra,

i'm impressed on all, many compliments......a couple of questions:


1) Why Rhodium plated and not silver plated? Silver is better than any coating, but Rhodium don't take oxidation...zero maintenance.

2) You have projected also the entire reflector design or it is stock thor reflector coated?

3) What brand is the ballast?

4) As you have balanced perfectly all cells to make a battery pack?

.....for now, just these questions ;)

:wave:

Re: NOT JUST ANOTHER THOR MOD !!

Rhodium is the most durable, is very hard and can easily cope with the high levels of ultra violet light produced by the lamp.

The original Thor-reflector has too many imperfections in its shape and can only be used with larger filaments or with HID.

The ballast is a Auerswald.

The batteries are hand picked and checked on their capacity.

Very nice! Good Job!

Can you post a large pic of your Avatar, it also shows the smooth reflector.

That light looks awesome, a real Throw King!

"just another mod"?? :huh:

Dude, that's awesome! Next thing you know, you'll be rebuilding a tank light. :)

Nice job.

Way to go! This light needs a catchy name so we can find it in a search months from now.
How about "Master-Blaster" ???

(bonus points: remember what movie this is from?)

Re: NOT JUST ANOTHER THOR MOD !!

Awesome light. How much does that thing weigh? That is a lot of batteries. It has got to be pretty heavy right?
