This lamp is a retrofit for 250W mercury lamps, and designed to operate on 250W mercury ballasts. If this whiter color is actual, the lamp is overdriven as a result of using a wrong ballast.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

I used 250W ballast for MV lamps. Working current, measured by current clamp, was 2,05A vs 2,15A
