Led Tube Light Lumens Per Watt

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.

Led tube light lumens per watt.

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. The greater the lumens the brighter or more intense the light. The t stands for the tubular shape of the light bulb and the f stands for the bulbs fluorescent wattage equal. That s almost a 33 percent efficiency increase over the efficiency of the spiral cfl from ge.

For instance a f32t8 is a tube that is one inch in diameter and about the same lumen. Up to 29 w. Of course not every fluorescent incandescent metal halide etc lamp will give its lumens. Understanding led tube size.

A 40 watt fluorescent tube for example is rated around 2300 lumens. Up to 11 w. 120 75 t8 u bend. Linear led light bulb ballast bypass tube power either end 5500 lumens 5000k single pin 120 277v 10 pack.

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. T8 4 ft. That s nearly 75 lumens per watt.

115 90 t8 3 ft. 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. To replace it with the same intensity led just look for one that rates 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. Actual light output may vary by product. Up to 9 w. Led tube sizes are determined by the diameter of the tube and the fluorescent wattage it s replacing.

Fluorescent tube lighting produces a record 200 lumens per watt 200 lm w. 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. The lightbulb lumens to wattage chart below will help you understand which led bulb is comparable to your current incandescent bulb. Lumens per watt lpw is a key measure of efficacy in lighting.
