Icecap 660 ballast

[bkvreef]

I presently have an Icecap 660 ballast.
It has several different wiring directions. I have it wired for my retrofit t-5's that are 80 watts and 60".
I noticed that there is another wiring for four lights.
Can I set up another 80 watt?

You can wire 2 or 4 bulbs....you cant do three though.

Out of the IC instruction book for a 660-009
660
2 lamps 16' max 2 X 8',6,5,4 or 2
3 lamps 15' max 3 X 5',4 or 3
4 lamps 16' max 4 X 4',3,2
Go to the IC web page for wiring three bulb. I don't think the 660 drives the longer bulbs as well as the 4' but I thnk they say you'll get 90w-95w out of them.

You can drive 3 lamps with them, and the lamps can be of differing lengths, as long as you don't exceed 72" on a single lamp, and do not go over 16 total feet of lamps, and 440 total lamp watts.
However, My experiences with mixing lamp sizes/wattages has been... disappointing. I've found that when mixing different lamp sizes, the smaller wattage lamps have severely reduced life... and I mean VERY severely. I was going through a set of lamps per month before I took them out and rewired to run just the bigger lamps.

So I presently have 3 x 60" so I will probably be best to leave it at that then.

For the T5 lights the 660 can run as many as 4 lamps for the 54 watt and smaller T5s/ For the 80 watt lamps you are maxed at 3.
