M20LED Illuminator module

Introducing the M20LED Illuminator as a direct replacement for the Wild M20, M21, and the Q-Illuminator for the M11, M40, etc.  Basically, any Wild microscope that uses the OQ49W bulb socket can be directly replaced with this new LED.  The OQ49W bulbs (aka 70249B) are getting hard to find and expensive.  We have upgraded several M20's in the past with fiberoptic flexible illuminators, but this is a much more elegant solution.  Brighter, even illumination, and cooler - the M20LED module breathes new life into those older Swiss microscopes.
