To add to above, the Herpstat 4 can control 4 things. So, that can include lights if you're not using it for anything else. I have a Herpstat 2 on two enclosures, controlling the heat on each. But, the LED lights are on a smart switch, and goes off and on every day at the same time.

But in general, I agree that putting the LEDs on the Herpstat is overkill. But, if the Herpstat port is free, go for it.
