Direct sunlight is around 100k lumens and uses no amount of energy per hour. This was an inefficient way of lighting and there have been many advances, such as the introduction of fluorescent and compact fluorescent lighting as well as metal halide ...With traditional tungsten bulbs, it takes 1W to release 15 lumens. But with LEDs, 1W produces 60 lumens or more. So a 60W tungsten bulb may emit 800 lumens of light, but a 60W LED light could release over 2,400 lumens per bulb. That could easily ruin your eyesight, so you need to be really careful.Lumens let you buy the amount of light you want. So when buying light bulbs, think lumens, not watts. 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 fewer ... CFLs provide a lot of options to the Indian consumers and they are available in multiple shapes, watts and color temperatures. The wattages available vary from 5 to 85 with a lot of options of choosing something in between the 2 numbers. They provide better brightness (lumens) per watt and thus are a good replacement of incandescent bulbs.Now that we understand watts and lumens, we can use both terms to come up with lumens per watt or "efficacy" (or "luminous efficacy"). This is a measure of how well a light source converts energy (watts) into light (lumens). The old technology of tungsten incandescent bulbs only had an efficacy of about 15 lumens/watt. LED technology ...Most modern fluorescents have efficiencies that range from 40 to 80 Lumens/Watt, with triphosphor fluorescents (the kind of phosphor used on compact fluorescents) working on the range of 50-70 Lumens/Watt, so just multiply this by the number of Watts and you get total Lumens.
