Like the ink-jet printer nonsense. Loads of nominally working video projectors around where the lamp has worn out after its 1000 to 2000 hours and a complete new projector is a little more than the cost of a replacement discharge lamp . Anyone done a conversion to high power LED emitter lamp? tips/pitfalls ? Obviously a number of opto-coupler functions need fudging as well as disconnecting the original lamp supply and HV ignitor sub-circuit lamp supply input side optos , ignitor-on , lamp on, half/full brightness output side optos , ignitor cct ok, lamp on (drawing correct current) confirmation Perhaps should only consider projectors that allow colour temperature setting within the menu structures any other considerations? I just saw reference to this LED lamp cluster , anyone sen the spec of the beam angle for it
