Light bulb wattage conversion

Lumens are the new unit of measurement for light bulbs. For decades, we’ve been buying light bulbs according to wattage. But as energy efficient, low- watt light. Buying light bulbs used to be much simpler: light fixtures were listed with a maximum wattage and buyers would simply purchase a corresponding bulb. Using the chart we can see that if you want to replace a 40W incandescent light bulb with a compact fluorescent (CFL), you will likely need a 7W CFL.

Designed for bathroom vanities or anywhere a globe bulb is require these bulbs produce light equivalent to a 40- watt incandescent bulb, yet only consume watts of power. Dimmable from 1 to , these bulbs have a 2degree beam angle to cast light in a wide area. Currently, the equivalent wattage can vary slightly between different bulbs and different manufacturers but most good bulbs will carry a conversion table on the packaging to help you to decide which bulb you need. The old days of selecting light bulbs by watts are over.

Use our lumens-to- watts conversion chart to choose the right LED bulb for your application. The good news is that determining the wattage you need from energy saving light bulbs is as easy as comparing the wattage currently used in lamps or overhead lights and comparing it with the corresponding energy saving light bulb wattage in the table below. Use this chart to see equivalent watt and lumen output for old-style incandescent and the three types of energy-saving bulbs (LEDs, halogens and CFLs).

As a rough guide, around 4lumens would be suitable for a bed-sized table lamp, whereas you might want between 5and 0lumens in total (from more than one bulb) for a good-sized living room.

Because energy efficient bulbs use considerably fewer watts , we now use lumens, which measure brightness, to select new bulbs. While there is no simple conversion formula, LED bulbs tend to be more energy efficient than incandescent bulbs at lower levels of brightness than they are at higher. We all know how much light a 60- watt bulb will produce.

But the brightness of new CFL and LED lightbulbs are measured in lumens, not watts , so heres a chart to help. The standard light bulb wattages you may be used to do not apply to LED bulbs , check theis useful comparison table below to see exactly which LED light bulbs you need. The rules have change though.

In fact, a 60- watt LED just may blind you. When replacing traditional incandescent or halogen light bulbs with a more energy efficient LED lighting system, it is important to understand the appropriate wattage. The comparison chart below shows you exactly which energy-saving light bulb or LED lamp you can replace your old incandescent light bulb or halogen lamp with to get the same amount of light (i.e. the power expressed watts ). Comparisons for the most common sizes are in the table below. A 9- watt fluorescent bulb , in this case, is equal to a 40- watt incandescent bulb.

Differences will also occur between types and sizes of light bulbs. For years, people have chosen light bulbs by the watt , learning over time about how bright a typical 40- watt or 60- watt bulb is. But wattage tells you only how much energy a bulb uses — not how bright it is.

An old-fashioned incandescent light bulb (no longer available) produced 7lumens and used 60W of power, whereas a new energy efficient LED uses only 10W. That’s an energy saving of around $per year for each bulb (when used hours per day). On dimming systems based on Xor Power Line Carrier (PLC) control technology, LEDs may flicker when modules are communicating due to the small fluctuations in power on the line. How many bulbs do you have in your house? On average, how many hours per day are your lights on for?

Watts - the amount of energy a light bulb uses. Bulb replacement wattage. CFLs and LEDs have a lower wattage than incandescent bulbs , but emit the same light output. Often used in recessed downlighters and spotlights, this wide range of GUbulbs is available in a variety of lumens, colours, shapes and styles.

The lower the watts , the lower the electric bill. Why not us our conversion tool and the right lampes for you. Using the wattage of your current halogen lamps, you can decide whether you want a brighter, dimmer, or equivalent LED alternative. You can select a non-dimmable or dimmable LED lamp that will allow for the light to be softened or brightened dynamically. The last choice would be to choose your light colour out of the following.

The brightness of LEDs, however, is determined a little differently.
