The bulbs are probably not a good deal. I've got a bunch of 5500k fluorescent bulbs I bought from Target for around $4 a piece. I'm not sure if they interfere with sound equipment.
Home Depot sells 150W
Home Depot sells 150W versions of these bulbs. That is what I use in the fill-light kit.
They are only useful in a few specific scenarios. They are daylight matched, so you can either use them in conjunction with the sun - or not at all. And since they do not emit a whole lot of light, using them with the sun rarely works.
You are better off using a 1k halogen work lamp and putting a daylight gel on it. $30 total investment for 15X the light you'd get from the best daylight florescent bulb.
I only find these small bulbs useful when trying to subtly change the lighting by clamping on a fill.
