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. WebThe resistance of a light bulb filament changes with temperature, but if we ignore this, we can at least roughly estimate the current flow and power dissipation in the series circuit. We have 120 V/ (360 + 360 + 360) ohms = 1/9 A. The power dissipated in each bulb is either (1/9) 2 × 360 = 4.44 watts, or (1/9) × 40 = 4.44 watts. WebLight color is measured on the Kelvin (K) temperature scale. Some bulbs offer more yellow light, while others offer a white or blue light. A lower Kelvin rating means more yellow light, as higher means more white or blue. Soft white bulbs — which fall in the yellow range — are ideal as bedroom or living room light bulbs, while warm white ... iron creek properties asheville nc
