WebJan 21, 2012 · SW Ohio. I can only speak for the Samsung MR16 bulb I reviewed in this forum a week or two ago. It has a regulated driver and it doesn't matter if the voltage is 8 or 16 volts DC, it puts out the same amount of light. It falls out of regulation under 8 volts (~7.75v). On a 12 volt AC transformer it performs the same. WebFor this much voltage, if this was the voltage across that device, then the power across that, power dissipated would be 50 watts. But clearly, in this example, the voltage across the …
