Wattage is a measurement of the power that a traditional bulb outputs and is often used to get an idea of how much light the bulb outputs. In LED bulbs, however, wattage is not talked about as much.
This is because LED bulbs don’t consume as much power as halogen and incandescent bulbs and their brightness is therefore discussed in lumens. Lumens directly refer to the amount of light output opposed to the power that they consume. That said, you can have a general conversion of lumens to wattages, so you can still purchase lights according to the light power you need.
Before deciding the wattage amount you want to use, think about what the purpose of the lighting is going to be. If you want accent lighting, lower wattages of three to six are ideal. For general illumination, opt for medium wattage amounts, and higher wattage for security.
The beam angle you choose also matters. Narrower beam angles can concentrate light and appear brighter while still having lower wattages. Wider beam angles will diffuse light and make it seem a bit dimmer, therefore requiring higher wattages to make up for it.
A general rule of thumb for lighting various locations around the house is as follows:
- Front door and porch areas: 6W to 10W
- Garage and driveway areas: 10W to 15W
- Garden Walls and features: 3W to 6W
- Patio and entertainment areas: 6W 10 12W
- Side passages and alleys: 8W to 12W
- Rear facade areas: 10W to 15W
