Led tube sizes are determined by the diameter of the tube and the fluorescent wattage it s replacing.
Led tube light lumens per watt.
That s almost a 33 percent efficiency increase over the efficiency of the spiral cfl from ge.
Up to 29 w.
Fluorescent tube lighting produces a record 200 lumens per watt 200 lm w.
For instance a f32t8 is a tube that is one inch in diameter and about the same lumen.
A typical 40w equivalent led light bulb the cree standard 40w replacement led uses just 6 watts of electricity to produce 450 lumens.

Led lighting can cut costs down drastically with its efficiency.
Up to 11 w.

The lightbulb lumens to wattage chart below will help you understand which led bulb is comparable to your current incandescent bulb.
To replace it with the same intensity led just look for one that rates around 2300 lumens.
If you re like the majority of businesses that are converting their lighting to led and your primary goal is energy savings one key metric to look at is lumens per watt.

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.
Lumens per watt lpw is a key measure of efficacy in lighting.
The greater the lumens the brighter or more intense the light.
Breaking the barrier the new prototype lamp marks the first time that lighting engineers have been able to reach 200 lm w.
By creating the world s most efficient warm white led lamp that uses half the energy of the current most efficient lamps on the market philips has set a new benchmark in led innovation.
Understanding led tube size.
Of course not every fluorescent incandescent metal halide etc lamp will give its lumens.
Linear led light bulb ballast bypass tube power either end 5500 lumens 5000k single pin 120 277v 10 pack.
Use the chart above to determine exactly how many lumens are in a watt and vice versa.
Output and wattages based on most common products available for each medium screw based light bulb.
That s a lot of light for such low wattage.
The t stands for the tubular shape of the light bulb and the f stands for the bulbs fluorescent wattage equal.
T8 4 ft.
That s nearly 75 lumens per watt.

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.
A 40 watt fluorescent tube for example is rated around 2300 lumens.
