Is anyone familiar with Yuji VX emitters? I was looking for a high CRI emitter for the microscope. Are they the same as the VTC series? Spec: SMD Chip model 9W-VX-5000 9watt , - Vf 29 -If 450mA. I plan on putting this in my Zeiss microscope, to replace the 30watt halogen lamp. What would be a good dimmable driver to use? Is this an SMD, or is it a COB emitter?
