that ballast is the shit ..........built in timer remote control digital pulse (the lights they offer are higher lumens then the counter part have a look) ........by the way since it is digital u can Select a watt 400/600/1000 .......those dimable ballast are not good they lower the amount of power it sends tho it does not adjust .......so when u put a bulb in and use it on anything other then 100% it is doing damage to the bulb lowering the light and altering the lightwaves (since it not at 100% it not working correctly does more damage and since all the engery it needs is not passing the lumens and lightwaves are off )..........dimable is bad ..........select a watt is good
now for the hood anything will work aslong as the plug head matches ..................but u want to get yourself a cool tube or sealed hood system (they make all kinds of sizes ...........6 inch dia is the normal)
