Fluorescent Light Wattage Equivalent

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.

Fluorescent light wattage equivalent.

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. 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. 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.

Lps are more efficient than hps but emit a very dim yellow light. 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. Read the package to choose desired illumination level. Universal voltage t8 16 watt 5000k daylight linear led tube light bulb.

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. By contrast a high kelvin figure like 4000k means the color is cool and white in appearance. While the math for the cfl bulbs is simple the led bulbs are even more energy efficient and durable than compact fluorescent light bulbs. Bulbs only come in certain wattages which make equivalent versions slight different.

The easiest way to figure out what bulb you need is by using an incandescent led conversion cart. Differences will also occur between types and sizes of light bulbs. Lumen wattage comparison. Linear t5 instantfit led tube light bulb daylight 5000k 48 in.

If you are going to replace fluorescent light with led lighting you must take into consideration the color temperature. Around 20 to 20 watts in a fluorescent bulb is the same as 100 watts in an incandescent bulb. Say you normally use a 60 watt incandescent bulb for example. The chart below illustrates the amount of brightness in lumens you can expect from different wattages of light bulbs.

For example a 3w led is equivalent in output to a 45 w incandescent. Choose between warm and cool light. 32 watt t8 40 watt t12 4 ft. P w φ v lm η lm w lumens to watts table.

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.
