IC660 and 5' T5 bulbs... how many?

[reefcam]

IceCap or Ash or Andy,

How many 5' T5 bulbs can I run with an IC660. I'm hoping the answer is going to be 3, but wanted to double check.

Thanks
Jim

You got it! Three is the max on a 660. Just make sure to heat sink the ballast.

Thanks. I have 3 IC660 and would like to cut it down to 2. Thanks a million.
