according to sanjay's website the bulbs would be a little higher in Kelvin on a magnetic ballast. I have them on icecaps and love the color. Nice crisp white color and the vhos add a tint of blue.
Oh cool, thanks for your reply.
I like the colour in the pics but they all seem to be on magnetic ballasts.
I was afraid that they went really yellow on an electric ballast.
are you talking about my pic? if you are, those are old old pics and not the XMs, but at first they'll be a little yellow, then whiten up within a couple weeks.
The one I posted up a bit is the XM's on magnetic ballasts i think. I like that colour but was unsure if the electric ballast would make it too yellow.
When I bought my ice cap for a 250 DE, I was told the XM's 10k wouldn't run on it (after I had bought them of course). And they were right, they did not run. They accepted the return with no problems. I don't know if this issue exists with the SE or not.
I am running them (IC 250w ballasts) to drive single ended XM10k lamps. I dont have any additional lighting on this tank.
To me its crisp white. I love the color.
