Ok, thanks for the added information.Looking at the specifications, the lamp has a 4K color temperature, so they should be in the white area and not in the pink tone for sure.It appears the issue would be bulb related and not the ballast but some ballasts may not be striking and providing the proper energy to keep the vapor ignited at the proper temperature.Bulbs have a gas inside and that is what ignites and provides the light you see. HID fixtures can sometimes be difficult to determine which is at fault, but the one true method is very easy.Take one of the bulbs that is producing the pink hew and swap it with one that is burning properly.If swapping gives the same pink hew and the other one is bright as normal, then you know it is your bulbs.If it burns correctly being moved and the other goes to the pink hew, then you know it is the ballast assembly. It may seem odd, but that is the best way with any HID or even fluorescent fixtures, because of the gases and ignition.I think it is bulb related, as I have seen cases produce odd results from some manufacturers.Only have to do one swap and that will give the needed information.Keep me posted,Thanks
