An upgrade

Find the constraint in your current setup before comparing bigger power labels.

Which constraint are you trying to remove?

Keep the power basis explicit.

The B1, RAY5, B4 and P3 pilot entries retain published power labels. The reviewed MIRA entries have separately stated optical-output and electrical-input values. Those labels and measurements cannot be combined into a single meaningful power ranking.

One reference, different power bases

Separate facts
≠

Original fact comparison, not an efficiency calculation, wiring diagram or power ranking. A name such as B1 “20W” stays a label where its optical basis is unresolved; source type, process and setup may change the decision.
