The LED Upgrade Kit I
The LED Upgrade Kit I got from Microscope Central saved my Nikon eclipse E200 from being an expensive door stop. The LED light works very well. Installation was challenging but working with an assistant it took less than two hours. It helps to have a good selection of tools for working with microscopes or other delicate mechanical instruments. The step by step directions are easy to follow, with photos of each stage. Note that a blue filter helps with color balance for photomicrography.
