What is brighter 60W or 100W?

Answer: The bulb rated at 100 W will be brighter. When both bulbs are connected to the rated voltage, they will dissipate the rated power. The brightness of a bulb depends on the power it dissipates, so the 100 W bulb will be brighter than the 60 W bulb.

Which is brighter cool white or daylight?

Color temperature is measured in Kelvin (k) – a thermodynamic temperature. The lower the Kelvin rating, the warmer the bulb will appear; the higher the rating, the cooler, and seemingly brighter, the bulb. When most people think of LED bulbs, they picture a bright white; or daylight (5000K).

Are daylight bulbs better for your eyes?
