Lumens Guide: Which LED Bulb Should I Buy?

In the past, we buy light bulbs based on watts, however, in today’s modern era, higher wattage does not mean having a brighter light, but rather, a higher wattage only means higher electric bill. Lumens is the new measurement use today, and what’s good about this is that it’s always accurate. With that in mind, it leaves us with the question of “How many lumens do we need?” The answer is it depends on your purpose and how big your room is. Below is a rough guide to help you decide, courtesy of Engineering Tool Box:
