CoolLED pT-100 White Light LED Replacement Illuminator

The pT-100 (formerly the pE-100wht) is a compact and simple-to-use LED illumination system for transmitted light applications and comprises a pT-100 LED Light Source, control pod, and power supply.  The user is given instant on/off and intensity control in 1% steps from the manual control pod which can be positioned close at hand.  Adapters are available for most new and older research microscopes to replace 12V/50W or 12V/100W Halogen lamphousings.  Please email us a photo of your microscope, and we'll confirm which adapter is correct.
