Does the Cloudray CR40 come with pre-soldered high voltage leads?

Yes. The Cloudray CR40 comes factory-equipped with pre-soldered high-voltage silicone wire leads and molded insulating silicone boots on both the anode (+HV) and cathode (-GND) terminals, eliminating dangerous soldering onto delicate glass tungsten pins.

What is the expected operating lifespan of the Cloudray CR40?

When operated under 15mA continuous current and maintained with distilled water cooling between 16°C and 20°C, the Cloudray CR40 has an engineering design lifespan of 2,500 to 3,000 working hours. Over-driving at 20mA+ reduces lifespan to under 200 hours.
