Still might be interested, my 12.5 k's are pretty white.

Actually if they have never been fired on before, there is a little rolling ball inside the glass tube that rolls around until its turned on then the little ball will evaporate. Thats the way it is with the single ended and i'm sure its the same with the DE.

I've never seen these rolling balls in the 3 times that I've purchased DE bulbs from J&L. I just checked my bulbs and they're not in them. I would think that it is only in SE that the ball is there.
