I have been wondering as of the last 4 months if the M250R2 is in the PROCESS of being retired. I ask this because in the Marion, IL Ameren operations center, it appears as though they have replaced the M250R2 250w HPS luminaires with M400R3 250w PSMH & 400w HPS luminaires. In replacing cobra heads around here, where an M2RR or M2RC would go, an MSRL25 is being put up instead. It's been 4 months since I last saw an M250R2 installed. Old M250R2s that die are being replaced by '40' HPS luminaires or '25' PSMH (with sodium lamps installed in both.) But no new '25' HPS M250R2 have been installed. Now, I know the M400R3s are about double the price of an M250R2, so I'm simply wondering why. Now any new 400w M400R3 has a Yellow NEMA tag indicating it is for use with HPS lamps, and they are bright as a gasoline fueled fire. The 250w M400R3 has the Red/White '25' NEMA tag indicating it should have a PSMH lamp installed, but a HPS lamp is ALWAYS installed, and it "appears" dimmer than the same lamp does in the M250R2. (I mean it looks more like a 150w-200w HPS, but it is fully warmed up). So back to the original question. Is GE or Ameren in the process of retiring the M250R2 to make more room for the Evolve family? Sorry this is so long, but I wanted to be thorough.
