Used to (250W DE), but switched to Ushio because the Hamilton's were not lasting. One bulb lasted 6 months, and the other two only got a month each before burning out (posted
here).
I really liked the colour, was the crisp white with a bit a blue. Find the 14K Ushio look yellow in comparison.
Did find the look with the actinics a little better than just with the Hamiltons alone.
