In the past, manufacturers relied on wattage to determine the brightness of a traditional light bulb, but with LED lights, the number of watts no longer indicates brightness. So, when choosing an LED bulb, it's better to look at the luminous flux instead of the power. The luminous flux of a bulb is measured in lumens (lm) and is stated on the packaging. In the comparison table below showing previous Philips bulbs, you can see that the Philips Ultra Efficient LED bulb offers the best values.
