Difference between Osram NAV T 4YR and SUPER 4YR « on: September 29, 2026, 02:22:32 PM » Author: Jovan
I noticed that some Osram HPS lamps have written SUPER 4YR while others are just 4YR. Is there any difference in lamp specs ?

The "Super" meaning higher output, because of higher xenon pressure.

The Super 4Y, don't have enhanced blue-green spectrum. It only brighter, and also have longer lifespan due to higher xenon pressure.

No. Osram sold both 4Y and Super 4Y at the same time.
