All of our devices are built with Photonis Echo Gen2+ White Phosphor tubes. Why? Because from our experience sampling most of the Photonis line, they offer the best combination of price-to-performance.
Echos have an EBI range from 0.1 to 2.5 with most falling in the 1.2 to 1.8 mark.
If you have specific EBI requirements, you can choose the Hand-Select option and we can work with you to pick the right tube out of our inventory.
