Hello,
I'm Alexander from Germany and new at the forum.
For quite some time I was reading here without a Account.
Im especially interested in spotlights and unusual equipment.
Besides some custom HID builds I have a AEG XSW 30 Searchlight aswell.
Here I wanted to present my latest build, it is somewhat low cost and has a super high range.
It works without expensive optics and only a 300mm Fresnel lens for like $20.
As a front bezel I used a 3mm steel plate and drilled some holes on the milling machine.
The leftover parts from the middle will be the back of the frame:
Since it has to be somewhat lightweight it is a basket construction from 3mm steel wire.
Lamp and Ballast are mounted in some cheap drain pipe.
The one on the left is a Osram P-VIP 240/0.8, the right one a Osram P-VIP 180/1.0
The first part is the wattage and the second one is likely the arc gap.
The basket was wrapped in some acoustic foam where air can pass through it.
At the left end there is a radial blower which pulls air over the Lamp and the Ballast inside the pipe.
In the front there is the 300mm fresnel lens with a focal length of 380mm.
The lamp has a ellipsoid reflector which has two focus points, one between the electrodes and one around 20mm in front of the lamp.
So the optics work somewhat this way, so there is no need to remove the stock reflector from the lamp.
I added a mount for a tripod so the lamp could be positioned:
At 18:00 it was getting dark so a first test was done, the brightness is somewhat similar than to the eye.
The target(some hay bales) are 1070m away.
At 19:00 it was basically night.
