My 6500K Philips daylight spirals are from HD - I'm assuming we're talking spirals here. If you're not able to find something in the 5000K - 6500K range and need something right away, most 'cool white' bulbs are 4100K - still not ideal, they wash colours out a little, but they're not orangey like 'soft white' bulbs (2300K - 2700K) and are generally quite cheap.
