Indoor question about my ballast

[listen2marley]

this is the set up I bought
http://www.htgsupply.com/Product-HTGSupply-150w-High-Pressure-Sodium-Grow-Light

but then ended out uprgading the bulb to a 400W bulb. two questions, since the balast is 150W should I not be running a 400W bulb? Also how do I know if its a digital ballast or not?

Just wondering because I just heard of people having issues with their digital ballast knocking out wifi signals and stuff and just want to make sure I dont screw with my neighbors or anything. any help would be appreciated. thanks

O man please don't put that 400 in the 150 ballast! that's not a digi ballast , i can see the magnet and coil. please don't start a fire.

you still cant change the wattage around on a digi unless you turn the knob. i use the apollos and have no issues.
that's a nice lamp bro. just use the 150 hps bulb. Im not even sure you can use a MH bulb.. but you can ask the vender.

you cant you will need a veg lamp to run MH
