Bulb variations between manufacturers

[Dan Goulder]

Have any of you run comparisons between tungsten halogen bulbs of different manufacturers? Have you found any variations in color temp between different brand names for FRK (650W), FKW (300W), or any other bulb types and wattages? Have you observed any significant difference in longevity?

Thank you.

I have had great success with Ushio, specifically their HPL575 vs Osram's version (it's not as clean of a light IMO).
