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??
