That one will work! 5500K (stark white) is an excellent spectrum in flouros, and if I can find 'em, I prefer 'em over the 6500K. It's resold by agri-sun, and is a good grow light.

These same type bulbs (42W twistys) are avail in 2700K at Home Depot, Lowes, Save-On, etc. Philips Marathon brand. Usually run about $12CAN/bulb. Which is about 1/2 of what's advertised for that one. You can get 2! Green packaging is 2700K, blue packaging is 6500K. (For Philips bulbs)

You can use 2700K for veg, too. No harm.
