Led tube light lumens comparison.
T8 tubes are probably among the most common tubes available so swapping them with the latest and best led t8 tubes has fortunately been made very easy.
Led tubes have almost only advantages compared to fluorescent tubes.
After being switched on these tubes light up immediately with their full light output without flickering.
Lumens are the measure of total light intensity from a single source in this case a tube.
What is a lumen.
Turns on instantly and delivers bright clear light.
What s the difference between it and a watt.
A 40 watt fluorescent tube for example is rated around 2300 lumens.
Because fluorescent lights are often installed in high ceilings in commercial sites there are additional savings because the frequency of changing bulbs is greatly reduced.
In terms of light output or lumens output a 20 watt led tubelight is similar to an old 40 watt t 8 or 27 watt t 5 tubelight.
To replace it with the same intensity led just look for one that rates around 2300 lumens.
These days several options of led tubelights are available in the market.
The greater the lumens the brighter or more intense the 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.
The lightbulb lumens to wattage chart below will help you understand which led bulb is comparable to your current incandescent bulb.
Lighting it s all about lumens.
And how do you understand what are lumens in light bulbs and light fixtures.
Lumen wattage comparison the chart below illustrates the amount of brightness in lumens you can expect from different wattages of light bulbs.
For example our newest t5ho commercial led tube requires 26 watts w and outputs 3334 lumens lm translating into about 130 lumens per watt lm w.
Easily replaces t8 or t12 linear fluorescent bulbs with no rewiring.
But what are lumens exactly.
Simply take your current incandescent watts and select the corresponding led bulb equivalent on the lumens brightness scale.
Designed to replace fluorescent tube bulbs these led tubes are available in 8 and 16 watts which replace traditional 25 watt and 40 watt t8 t10 t12 fluorescent tubes.
Compatible with electronic or magnetic ballasts.
Led lifetime means the length of time in hours until half of the led light sources maintain at least 70 of their initial lumen output b50 l70.
Replacing your older lighting for the new led fixtures and tubes with a better lumen rating can also occur via the t8 electronic ballast method in this case the tubes are compatible.
That s a lot of light for such low wattage.
