Increasing the amount of electrical resistance in the device increases the amperage drawn. The brightness can be related to the electrical inputs, but not really in this way . . .Fred said:Pulling 110 through a lot of wire may have caused the ballast to lose some brightness
Lots of dual-voltage devices work better at the higher voltage inputs.Lost said:I don't think they are any brighter but it does half the amps
A digital ballast would need to have regulated power supply - like a buffer that takes whatever crap that comes off the wall (or an alternator or battery or power supply really - all kinds of things use voltage regulators) and turn it into a steady state voltage using some capacitance and a tad of amperage.Sirius said:That makes sense sedate.. I am still using magnetic ballasts.. My buddy and I didnt think if were using a digi this would happen either.. but a more constant supply of power seems like it would make any device perform better..
across multiple lights its is more than realistic to see a small reduction over a 120vac setup.mace said:And before anyone says anything about it, no it doesn't save you money!
