Older Venture 250w PSMH Na-Sc lamp comparison

Top is a new tri-salt Philips HPI-T Plus 250w lamp.
Center is a new Sunmaster 400w Conversion (Na-Sc) lamp.
Bottom is an older 250w Venture PSMH (Na-Sc) lamp.

Common to all are the mercury & sodium lines and surprisingly the lithium line at 670nm. Lined up perfectly afaic. The richness of the the Sunmaster lamp is somewhat gone in the older Venture 250w lamp. Note the yellow Hg pair is more prominent in the older lamp. Visually the older 250w Venture lamp is distinctly bluer than normal Na-Sc lamps.

You can see my spectrum of Na-Sc in my comment of your former picture of Sunmaster MH spectra. I think that you even seen it before.

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.

So yes, I "stole" your spectra pic, I cropped and rotated it, then manipulated the contrast, brightness & saturation. Then finally I fit it in with the other spectra in the above pic. See the results & tell me what you think.
