If you are updating your light bulbs then no matter if you are updating your bulbs to halogen, CFL or LED, the chart below will help you convert your bulbs correctly so you know what wattage you need for your new bulbs. Did you know, for example, that a w incandescent standard bulb is the equivalent to just 18w in an LED bulb? The chart below should help you make the correct choice when you update your light bulbs:.
Below, we take a closer look at the things you need to consider when choosing the best light bulb wattage:. You should never buy your light bulbs in bulk and later use them randomly around the house. Adequate amount of light for each room depends on typical activities taking place there, as well as the size of the room. The living room probably deserves several separate light sources equipped with high wattage bulbs, but a small storage room would be better served with less luminous bulbs.
By customizing the wattage for each room, you can define identity of the space and make your home more comfortable to live in. Choosing the best wattage is not a simple matter of picking a number. In addition to standard general service light bulbs, you can also find a lot of other options in the market.
Incandescent light bulbs are available in the 15ww range, although these are being phased out. Halogen bulbs top out at w and give a different kind of light. Well, sort of. For so long, many of us have associated watts with the amount of light a bulb gives off.
In general, that works well with traditional incandescent light bulbs. A 60W incandescent bulb typically gives off around lumens. A 25W incandescent bulb typically produces around lumens — much less light. The photos above are representative of the technology, not specific product specifications. So, as you are comparing light bulbs, remember that wattage is a measure of how much energy the light bulb will use as it produces light, and the lumens will give you a measure of how much light it will produce.

To convert W to kW, divide the total wattage by 1, Imagine that you turn on those ten light bulbs and a 3,watt clothes dryer at the same time. The utility company needs to be able to supply enough electricity to meet that 4kW of demand at the moment you turn everything on. Your energy usage, though, depends on how long you keep everything on, which leads us to….
The kWh measurement is a way to quantify how much energy is used over a period of time. This can be calculated by multiplying the kW of energy consumption by the total number of hours the lighting has been operated. How much energy would you use of the course of a month if you turn them on for 10 hours a day? So why is kWh so important if you can compare lighting products based on wattage and light output? In the end, a significant portion of your electricity bill is based on your energy consumption in kilowatt-hours.
How about a practical example to explain the difference between kW and kWh? Price kWh : Enter the cost you are paying on average per kilowatt hour, our caculators use the default value of 0. To find an exact price check your electricity bill or take a look at Global Electricity Prices. Incandescent light bulbs have been discontinued from sale above a certain wattage in many regions, as they are not very energy efficient.
