Energy savings


Will there be a kWh savings by changing from magnet ballasts to electronic ballasts? Existing fixtures use 2 - 40 watt T12 lamps.

Thank you,
Mike

There could be if you switch to T8 35 watt tubes.

Hi Joed,

Thank you for your response.

So, there is not an actual savings if you just change the ballasts to electronic? You would also have to change the lamp wattage?

There could be. Some ballasts are more efficient than others. If it was a whole office building probably worth it. If is two lights in your basement I wouldn't bother unless the ballasts are bad and need replacing already.
