250 Watt Double Ended lights

I'm sure that RC will have something on those bulbs. I may be mistaken though, I'm not 100% sure BLV makes anything but a 10000K and a 20000K bulb.

Here is link to Sanjay Joshi's 10000K DE bulb comparison:

I'm not sure if it will help you, but you may find it useful. I forgot that Giesmann bulbs are also suppose to be quite good as well as the Aquaconnect 14000K which I have never seen in Canada.
