 >From a bit of reading it seems that my concerns would be physical form and equivalent wattage.  Appears to be plenty of T3 G4 type LEDs with acceptable equivalent wattage.  What am I not considering?  Any comments or pointers appreciated!! 



 	


     Looks like the OEM lamp is an incandescent

     20w lamp in a g4 envelope. No LED lamp in

     that same envelope is going to be a 20 watt

     device . . . it may approach the same total

     light output as the original with less than

     20watts of energy consumption but I'm

     skeptical. Further, no LED replacement

     will have the same radiation pattern.

     Pattern can have a profound effect on the

     quality of the projected image.



     The LED products are less expensive and

     risks for trying one are low. Give

     it a try and see what the display looks

     like . . . please share your discoveries.

Thanks Bob, my main concern was inadvertently trashing the 

Sandel somehow.  If that is a non-factor I'm game to see what the LED presentation would be like.  Will indeed report back when I've got some field test info!
