Rouge Pro G4
Best for people who want the widest spectrum, honest output numbers and real controls at a mid-range price.
- Eight published wavelengths, from 630 to 1060 nm, that you can dim one by one
- Two irradiance figures at 6 in (164 on a solar meter, 90 on a spectrometer) plus a linked lab report
- 3-year warranty and a 60-day return window
The catch: Rouge publishes no EMF figure for the Pro G4, and its successor, the Pro G5, was already listed at $1,233 with shipping from December 7. Buying the G4 now means buying last year's model at a good price.
