Blog posts — lumen value

Select the right lumen valueHave you ever bought a low energy light bulb and were disappointed by the level of brightness it gave out? You may have bought a bulb with too small a lumen value. Lumens are a measure of how bright a bulb is.With traditional bulbs, we used watts to figure out the brightness of a bulb. However, watts measure power consumption rather than brightness. Energy saving light bulbs use fewer watts, so it’s best to look at lumens.
