I'm running Reef Brite 250 watt electronic ballasts and I'm looking for an SE white/blue bulb that does not require an hqi setting to run properly. I'm currently using the Reef Brite 14k Twin Arcs and I find them to be quite yellow, look almost like a 6500k to my eyes. The bulbs grow and color coral well, but I would like more blue without having to use the XHO"s (I'm using the Reef Brite mh/led fixture). I'd like to use the XHO's for sunrise and sunset and then let the halides run for 6 hours on their own, the shimmer is so much better when the xho's are not on.
