Any 150w DE bulb should work in that fixture. The higher the K
temp, the bluer the bulb should be. Alot depends on the manufacturer. 2 diff brand 10K bulbs can look totally different.
Here's Sanjay's Performance Data
on all the 150w bulbs he tested.
PPFD - Photosynthetic Photon Flux Density, which is the amout of usable light the bulb puts out
CCT - Correlated Color Temp, which is the true K
temp of the bulb as tested
Also note the difference in results when a shield is used. You are using DE shielded bulbs.
The AB 10k bulbs look nice according to those results. XM (XDE) 15k looks like they have nice color, but not very good PPFD. I think cmor recently bought the Ushio 10k's.
Here's the results
for the 175w bulbs I use. Look at the CCT. These bulbs are a crisp white color.
