250 Watt electronic ballast
Electronic ballasts have many advantages over the old magnetic models.
They give off less heat, produce no hum and perhaps most importantly have a higher light output.
If you would like to work with an HPS lamp in the Bonanza 0.35 model, this is the best choice.
We recommend using this 250 Watt digital ballast in combination with a Powerlux reflector and Sunkraft 250 HPS lamp
At a height of 30 cm, this gives the light output below.
