Led Tube Light Lumens Per Watt

The t stands for the tubular shape of the light bulb and the f stands for the bulbs fluorescent wattage equal.

Led tube light lumens per watt.

Up to 11 w. Linear led light bulb ballast bypass tube power either end 5500 lumens 5000k single pin 120 277v 10 pack. A typical 40w equivalent led light bulb the cree standard 40w replacement led uses just 6 watts of electricity to produce 450 lumens. 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.

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. 115 90 t8 3 ft. The greater the lumens the brighter or more intense the light. A 40 watt fluorescent tube for example is rated around 2300 lumens.

Breaking the barrier the new prototype lamp marks the first time that lighting engineers have been able to reach 200 lm w. Lumens per watt lpw is a key measure of efficacy in lighting. Of course not every fluorescent incandescent metal halide etc lamp will give its lumens. That s almost a 33 percent efficiency increase over the efficiency of the spiral cfl from ge.

120 80 t8 2 ft. Up to 9 w. Actual light output may vary by product. The lightbulb lumens to wattage chart below will help you understand which led bulb is comparable to your current incandescent bulb.

T8 4 ft. Eti 43 watt 8 ft. 120 75 t8 u bend. Simply take your current incandescent watts and select the corresponding led bulb equivalent on the lumens brightness scale.

To replace it with the same intensity led just look for one that rates around 2300 lumens. Output and wattages based on most common products available for each medium screw based light bulb. Understanding led tube size. 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.

That s a lot of light for such low wattage. For instance a f32t8 is a tube that is one inch in diameter and about the same lumen. Up to 29 w. 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.

Fluorescent tube lighting produces a record 200 lumens per watt 200 lm w. Use the chart above to determine exactly how many lumens are in a watt and vice versa.
