Can anyone recommend a 250 watt se bulb that can work as a stand alone option on a standard electronic ballast without an hqi setting? I'm currently using reefbrite mh/led fixtures and I'd like to be able to achieve a blue/white color without using the xho's while the halides are on. The shimmer is so much better with only the halides running. I would be using the xho's for sunrise and sunset. I'm currently using reefbrite twin arc 14k bulbs and I find them to be too yellow.
