As bulbs in your ceiling are pointed down, all of the light produced by the LED bulb makes it into the room. See the Incandescent vs. CFL vs. LED light lumens chart: Wattage Lumens Useful Lumens LED 9W 800 lm 800lm CFL 20W 1000lm 500lm Incandescent 60W 1000lm 500lm Here you can ...
Light bulb types There are four prominent light bulb types: light-emitting diode (LED), compact fluorescent (CFL), incandescent, and halogen. For a helpful quick-select tool, check out our light bulb size chart! Now, let’s explore the light bulb types and codes you are most likely to...
How to Match Bulb Wattage to Light Fixtures When matching light bulb wattage to light fixtures, there are many factors to consider. Recessed lights, chandeliers, and pendant lights are the most common in residential buildings. Since chandeliers usually have multiple bulb holders, you can purchase n...

Similarly we cancalculate luminous flux(lumens)of a light bulb if we knowwattageandluminous efficacyof the bulb, by transforming the same formula: lumens = wattage * lumens per watt hour 10W * 60 lm/W = 600lm Lumen comparison How many lumens are in a watt will depend on thetype of bulb...
We have used the following number of efficacy (lumens /watts) to establish our wattage comparison figures:* Incandescent bulbs – 7 (LED bulb lumens / 7 = our comparison) Approximately 90% of all the power consumed by an incandescent light bulb is emitted as heat rather than visible light....

The site also has a handy light bulb base chart. 2. Determine how much light you need Wattage is no longer the best way to determine which bulb will be a direct replacement for the bulb that just burned out. LED bulbs use a lot fewer watts than incandescents to produce the same level...
We did a little experiment in Polly's room switching out light bulbs to demonstrate the difference a light bulb can make. First up, Lumens. Sources I'm sure you've heard about watts, but fortunately almost every bulb has become more energy efficient so while a box will list the watt equ...
