20 watt energy saving bulb what is the equivalent
How many lumens is a 20 watt LED bulb?
It is now also possible to buy energy saving halogen bulbs and a wider range of these is now being developed. At the moment, an energy saving halogen equivalent to 20W can replace a standard halogen of 35W and a 50W equivalent can replace a traditional halogen of 65W. Pretty soon, everyone will be using energy saving bulbs. Energy used: Watt (equivalent to a 20W standard incandescent light bulb) Uses up to 87% less energy compared to a standard incandescent light bulb. Lumens per /5(88).

It's efficient too, using just 65 watts to generate lumens of brightnatural light at Kelvin. That's the equivalent light output of ten 45 watt bulbs! For instance: 40 Watt incandescent lamp produces only lumens and uses 40 Watts of energy per hour.
Direct sunlight is around k lumens and uses no amount of energy per hour. To determine the needed lumensyou will need to multiply your room square footage by your room foot-candle requirement. For example, a square foot living room, which needs foot-candles, will need 1, lumens.
A square foot dining room, which needs foot-candles, will need 3, lumens. You probably know that LED bulbs run dramatically cooler than their incandescent cousins, but that doesn't mean they don't produce heat. LED bulbs do get hotbut the heat is pulled away by a heat sink in the base of the bulb.
LED light can damage eyeshealth authority warns. The "blue light " in LED lighting can damage the eye's retina and disturb natural sleep rhythms, France's government-run health watchdog said this week.

Lumens to watts table. Once you've found those two numbers, simply divide the number of lumens by the number of watts. That will give you the standard measure of light bulb efficiency, which is the lumens per watts. It's best to use the actual wattage of the bulb, not the so-called "equivalency" value. Not a measure of brightness ; instead, it's a measure of how much electricity or energy a bulb consumes to reach its claimed brightness.

How bright is lumens? For. The light production is so much more efficient that a 25 watt LED produces the same luminosity as 1 watt incandescent, it will also last 20 or more times as long, while producing more light and less fire hazard. Even a CFC bulb will do better with a 20 watt bulb out producing a 70 watt incandescent, but only lasting about 10 times as long.

In general, however, the wattage of most energy saving light bulbs will be within certain ranges, as shown in the table below. It is now also possible to buy energy saving halogen bulbs and a wider range of these is now being developed. At the moment, an energy saving halogen equivalent to 20W can replace a standard halogen of 35W and a 50W equivalent can replace a traditional halogen of 65W.
Pretty soon, everyone will be using energy saving bulbs. Inefficient traditional light bulbs are being phased out in the UK over the next few years.
The programme of phasing them out has already started and concentrates on bulbs greater than W. Types of Energy Saving Bulb Currently, there are three main types of energy saving light bulb. The most common is the compact fluorescent lamp CFL which is available in both bayonet and screw fittings and a variety of shapes.
They are already available for use in halogen spotlights and once technical difficulties are resolved, a range of bulbs for general use should be available. To ensure that the bulbs you buy are genuine energy saving bulbs, you should look for the Energy Saving Recommended logo.
