The short answer
If price is the only number that matters, the SereneLife costs less. If you want more heat and more in the box, the Pulse PRO is rated to ~160°F against SereneLife's listed 140°F, runs on 1600W instead of 1050W, and adds a built-in 660-850nm red light panel that SereneLife does not list. As of September 14, 2026, SereneLife's own store shows its infrared unit as backordered.
