Ricky Joe - I found this site (http://www.accessconnect.com/piaalamp.htm) in the Accessories pages, butt not sure if they have the specific lamp you're looking for. Check it out to see for sure.

Thanks guy's !
I also found out that you can get this lamp at Lowes or Home Depot. I'll find out this weekend and let you know.

I know you can get the Motolight bulbs at Home Depot or Lowes (butt they aren't the same beam spread, so be careful), butt I didn't know you could find PIAAs there. Hmmmmmm - be interesting to check prices. Lowest I've found the Dichroic bulb/housing for my 1100Xs is ~$38.00 --- bought 'em 'bout three years ago; can't remember where perzackly, butt maybe can find the receipt, if needed.

Has anyone done any research to see what, exactly, "Dichroic" is and does? I've just done some basics and so far, what I've seen is it's a way of making glass 'pretty'.

What'm I missing?

Zotter,

Think of it as a "band pass" filter for light frequencies. It uses interference principles from two different, very thin oxide coatings to selectively let certain frequencies(color) of light to pass while reflecting others. First use was to let the infrared (heat) out of the rear of reflector projection bulbs while passing only the desired light out the front to protect the film from heat.

That's pretty much correct, but doesn't really answer the question.

Dichroic filters change the light output from basic tungsten 3200K to some degree of daylight, generally between 4800 and 5600K. We used them for years in the film business on large tungsten or incandescent lamps to 'adjust' their color for daylight balance before HMIs became available.

Dichroic supplimentary lights work better with HID headlights as the kelvin temperatures (color) are similar.

Good stuff! Thanks guys :thumb:
