Hi all - new member here - great website -
I have an Infocus LP350 with a blown lamp (supposedly some of the these things have a dodgy power supply)
I bought a non-std 270W UHP lamp which lights up and I made a modified holder, but the output was dim - presumably due to a diff reflector shape - so I thought I would try a lens in front of the lamp - set up a test rig with a metal target and I can get a nicely sized circle to match the aperature of the DLP unit - BUT - I originally had white paper on my target and POOF - up she went almost immediately - so in focussing the lamp I am also concentrating the heat - my question is does anyone know what these units can take ?? - the aperature has a semispherical lens in front of the colour wheel unit and although I haven't stripped it down, it FEELS like plastic rather than glass
Even without the lens the heat generation immediately ion front of the lamp is quite high, so they must be fairly temp resistant -
Any assistance would be appreciated before I melt the projector!

Hi !
your need a 270w SHP,not UHP!
SHP is a DC lamp,the reflector is ellipsoidal,but UHP is a AC lamp.
if you need 270w SHP and the reflector , I can supply.

Thanks ywh - my error - slip of the mind- the lamp is an SHP - too many types available!! - Tho one I bought is electrically compatible but not geometrically - it's slightly bigger and has a diff reflector shape
ywh - does your reflector match the orig broken one??
The outside diameter of the front of the broken reflector is about 56mm and the dia of the recess in the ceramic 'ring' is about 57mm
the overall height including the rear ring is 39mm. The dia of the rear ring is 21mm to fit into the 22mm recess in the rear ceramic. Height of the rear ring is about 5mm - see attached photo
how delicate are the bulbs and where can I get lamp cement from (I'm in Australia)
Would certainly be simpler to rebuild the orig lamp but I'm still interested in the focussing issue - even with the orig lamp there must be a fair amount of wasted light not entering the DLP aperature - more precise focussing with the lamp means lower wattage and less heat

Hi ywh
I'm happy to do the assembly if only for the learning involved, but the reflector needs to be EXACTLY the same dimensions as the original otherwise it simply won't work
I saw a previous post showing a parabolic reflector of yours which was 75mm dia and 60mm focus distance - that one is too big
Do you have one the same size as the measurements given in my previous post??
If you have one the right size - how much for all the parts + cement and postage
