Fluorescent Light Wattage Equivalent

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.

Fluorescent light wattage equivalent.

Linear t5 instantfit led tube light bulb daylight 5000k 48 in. Say you normally use a 60 watt incandescent bulb for example. The easiest way to figure out what bulb you need is by using an incandescent led conversion cart. 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.

Choose between warm and cool light. Lps are more efficient than hps but emit a very dim yellow light. 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. 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.

Watts to lumens calculator lumens to watts calculation formula. The chart below illustrates the amount of brightness in lumens you can expect from different wattages of light bulbs. P w φ v lm η lm w lumens to watts table. 32 watt t8 40 watt t12 4 ft.

Leds require less wattage than cfl for the same amount of light. 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. For example a 3w led is equivalent in output to a 45 w incandescent. Read the package to choose desired illumination level.

While the math for the cfl bulbs is simple the led bulbs are even more energy efficient and durable than compact fluorescent light bulbs. If you are going to replace fluorescent light with led lighting you must take into consideration the color temperature. Differences will also occur between types and sizes of light bulbs. 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. Bulbs only come in certain wattages which make equivalent versions slight different.

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. Lumen wattage comparison. 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.
