Is my ballast too inefficient?

[Powernoob]

Hi all,

Just set up a 250W system indoors, however I'm a bit concerned about the ballast: I was expecting total system watts to be about 300W, but actually it's using nearly 340W. That means, I assume, that the ballast is using 90W to produce 250W useful power, which is only about 70% efficiency. This causes the ballast to get quite hot (about 65 celcius).

Should I be looking to get a different ballast? Does anybody have any recommendations?

Thanks

The digital ballasts tend to be more energy efficient. A lot because they run cooler than the magnetic ballasts a lot of use. Heat is always the enemy of electrical effeciency.
