Buying A 400w HPS From InsideSun

Hello all....again. I am purchasing a 400watt High Pressure Sodium light from InsideSun however I sent a couple e-mails to them with no response. Don't get me wrong their customer service is top notch but it's like they don't read far enough down my e-mail to see the questions since I have a habit of rambling on forever and ever. So my question was Does anyone know what brand 400watt bulb comes with the "InsideSun 400watt HPS system? I'm thinking it is a 400 watt GE Lucalox standard but I'm not sure. For any of you pro's out there I have another question. The Lucalox bulb has a CCT rating of 2.2K which is the range for blossoming and flowering so I was considering getting the upgrade bulb which is a "Eye Hortilux Super HPS" as it is supposed to have 25% more blue light in the blue and green spectrums which all you old skool growers know. However that bulb's CCT rating comes in at 2.0K which is still in the deep red and orange spectrum. So what's the big difference? I think I may just have to get a Eye Hortilux Metal Ace Conversion Bulb instead but catch me if I'm wrong before I buy it. Thank you for listening to my stoned ass. Have a good day.
