Lighting for caulerpa in my refugium

[baruchbl]

I made a small refugium and i want to grow Caulerpa inside the refugium.
Do i can use a household fl Osram Bulb day light or i need a special bulb for aquarium plants?

As long as its daylight spectrum - 6000K - 10000K.. and I use more towards the 6000K end.. you should be fine. Macroalgae seems to be very forgiving with respect to light. A single 15watt fluorescent (NO) bulb over a 10gallon has grown Caulerpa for me, though I was not trying for high production to remove nutrients. More for pod culture.
