Simply put, the market is changing. Previously, we looked at how many watts did the light give. With the advent of LEDs, they use a different measurement to show what this lamp can generate, lumens. According to the US Department of Energy, they listed this chart:
The brightness, or lumen levels, of the lights in your home may vary widely, so here’s a rule of thumb:
- To replace a 100 watt (W) incandescent bulb, look for a bulb that gives you about 1600 lumens. If you want something dimmer, go for less lumens; if you prefer brighter light, look for more lumens.
- Replace a 75W bulb with an energy-saving bulb that gives you about 1100 lumens
- Replace a 60W bulb with an energy-saving bulb that gives you about 800 lumens
- Replace a 40W bulb with an energy-saving bulb that gives you about 450 lumens.
So when buying replacement lamps, these numbers will make it easier to make an informed choice.
