This is my 2nd Short Arc Mod, a sequel to the Mega Blaster as seen here:
This light has approximately 20 Million Beam candle power, the second longest throwing spotlight behind Ra's lengendary Maxa Blaster! Exact CPs to be measured at 100 meters distance coming this spring
I wanted to keep the name in the MB family, The Moon Blaster name
was inspired by this thread Maxa Beam vs. the Moon:
The photo was amazing: http://www.candlepowerforums.com/vb/...d.php?t=199795
Since the Mega Blaster did 6 Million cp on 4.5" lens, the Blitz is 9" reflector,
when you double the diameter, you get roughly 4x the CPs, thus the performance for the Moon Blaster Target over 20 Million of real CPs, at ~7000 Lumens, itll blow even the enhanced version of Maxa Beam (12 million cp version) out of the water with both throw and lumens!
I know I wanted to go with 9" reflector host. Not sure which one I want to go with, I got both. I compared the popular 15Millip CP Thor style host (A Camo Thor clone in the photo) Lightforce Blitz 240 before deciding to go with Blitz for 3 reasons:
1, It looks a lot smaller than the Thor 15 Mil type
2, The reflector looks like much better quality
3, It has Focus ability, at this level of CPs, a proper re-focus upon target distance change can easily gain a few million cps.
Again, I am taking the Ballast from DLP Projector. Instead of short the lamp On signal, I wired a switch to it, so I can shut the lamp keep the fan running for the after-cool (the red yellow Wire). I also kept the small board above the ballast that supplies 12v to the Fans kept the two fans for collling the ballast.
I used the same switch as factory one mounted at where the VGA port used to be to make it look natural (The Switch on Top)
Testing with the Factory P-VIP lamp that came with the Projector: Everything works!
One more thing I should mention: MY ballast has two Lamp control Signal
that need to be tricked. Besides the one I wired a switch on (Jumper the out put legs of Opto coupler), there was another trigger that was originally wired to a factory momentary switch. That switch will only be pressed when the OEM lamp is installed. When lamp door is open, it wont fire up. A safely feature I suspect may be on quite a few DLP projector models. I cut the wires soldered them together (The white piece with two brawn two blue wires, the momentary switch has two set of wires, no idea why).
Tricking the DLP projector ballast for me has been hit or miss. Here is
one that I was not able to trick: I was not able to fire up the ballast after taken everything apart neither was I able to put it back together
This is the same lamp as used in the Mega Blaster, 120W P-VIP P24 1.0mm short arc lamp,
So I am not go to repeat the specs here. However, for use with Blitz, I must take the bulb out of the built-in reflector.
The two Bulb I peeled: left Philips UHP 120W, Right Osram P-VIP 120W
I'll be using the P-VIP as it has a smaller arc cleaner arc chamber, possible less hours on it (Both lamps were used with unkown hours)
The Blitz Blitz 100W lamp holder is Bi-Pin, I needed to re-mount the P-VIP lamp with a ceramic holder. After extensive internet ebay search: Look what I found: A Ceramic Tube Socket that I think its going to work!
I got the 12 Pin style that has an diameter almost perfect fit for the Blitz,
took some pins out, kept a few to allow me to pull adjust while testing it.
Before I mount the lamp, I wanted to make sure it's still working.
I had used needle nose plier to break the glass reflector (I did this with a full face shield on, safely first! The Lamp can explode, this is dangerous! Search projector lamp explosion on U-Tube see for your self, some dudes got bloody)
Testing the bare lamp with the help of alligator clamp, Yeah still works!
Test fitting making sure the Arc location is where the factory bulb filament used to be, so I know its within factory focus range.
The lamp is potted to the center hole using Automotive Exhaust Potty with a home made aluminum spacer. Now, I need to let it cure overnight.
