Fluorescent Light Wattage Equivalent

By contrast a high kelvin figure like 4000k means the color is cool and white in appearance.

Fluorescent light wattage equivalent.

Leds require less wattage than cfl for the same amount of light. Differences will also occur between types and sizes of light bulbs. Led bulbs require much less wattage than cfl or incandescent light bulbs which is why leds are more energy efficient and longer lasting than their competitors. Color temperature measurement is in kelvin k and most colors range from 2500 to 6500k a lower kelvin figure means the color is warm and tends to be closer to orange.

Watts to lumens calculator lumens to watts calculation formula. If you are going to replace fluorescent light with led lighting you must take into consideration the color temperature. Linear t5 instantfit led tube light bulb daylight 5000k 48 in. The power p in watts w is equal to the luminous flux φ v in lumens lm divided by the luminous efficacy η in lumens per watt lm w.

New led bulbs are available in cool white light which is ideal for task lighting and warm light commonly used for accent or small area lighting. But as energy efficient low watt light bulbs like cfls and leds have become readily available watts have become an unreliable metric for selecting bulbs. Lumen wattage comparison. Say you normally use a 60 watt incandescent bulb for example.

For example a correct replacement for a 60w incandescent bulb would be a 15 watt cfl bulb 60 1 4 15. The easiest way to figure out what bulb you need is by using an incandescent led conversion cart. Energy saving lamps have high luminous efficacy more lumens per watt. A 9 watt fluorescent bulb in this case is equal to a 40 watt incandescent bulb.

The chart below illustrates the amount of brightness in lumens you can expect from different wattages of light bulbs. Instead of focusing on wattage which measures power or energy use manufacturers are indicating the brightness of their energy efficient bulbs according to lumens which measure light output. 32 watt t8 40 watt t12 4 ft. For example a 3w led is equivalent in output to a 45 w incandescent.

Fluorescent tube light wattage led equivalent wattage 70 watt 24 watt 58 watt 22 watt 35 watt 18 watt 20 watt 9 watt led equivalents to sodium lighting sodium lights can be high pressure sodium hps or low pressure sodium lps. Around 20 to 20 watts in a fluorescent bulb is the same as 100 watts in an incandescent bulb. Universal voltage t8 16 watt 5000k daylight linear led tube light bulb. Choose between warm and cool light.

While the math for the cfl bulbs is simple the led bulbs are even more energy efficient and durable than compact fluorescent light bulbs. P w φ v lm η lm w lumens to watts table. Read the package to choose desired illumination level.
