>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!! Very Happy


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!
