The fan I have is fine now, but it's aging, and I'm worried about the time between its failure and the time I shut off the lights. I work, and I worry about the ten hours when I'm away. I've split the two--light and fan--between two circuits, but one time the fan's fuse blew and the light's didn't. Nearly ruined my crop. I've since kept them on the same circuit, but I don't want a repeat. I like the idea of the CAP HLC-3e.
