Hi folks,
this is my latest project. A 5” psone with the new light engine.
These are the components:
- 5” psone-panel ( native reso 320x240) I know, it’s low. Its just 4 fun
- 150 W HQI-T naked ( stripped pyrex shell)
- dremeled, dichroic par20 reflector
- ir-filter
- fresnel f 210/210 mm ( approx: 8 ¼ “)
- fs mirror surplus
- lens 9” surplus
- condensor surplus
- ballast, ignitor from ebay
- 2 radial blowers
- 1 axial blower
enclosure:
- ally sheet 1mm
- mill finished ally extrusion profile ( adamhall.com )
- beech planks
- inner dimension: 10.4“ d x 12.4” w x 5.9“ h.
Here are some pics of the results and of the housing. Distance 114” . PJ is 60”.
Larger than 60” will show perturbing screen door effect.
exterior view:
from within:
light engine: this is how I built it
my cam is fuly automatically, so I cannot adjust the exposure time L
I have to paint it black inside. The brighter area is a reflection of the ally inside I have to paint black later on.
The dark spot can be seen on the last pic (lower left corner) results from the heat.
I’ve to improve the air flow coz the controller is tightened on a plywood plank stops the air flow to an “air jam”.
As you can see, the reflector works very efficiently. ;-)

An externally hosted image should be here but it was not working when we last tested it.
