Choosing an led light bulb.
1 watt led lumen output.
Our products are amongst the highest efficacy available in the industry.
Efficacy the number of lumens a bulb produces for each watt it.
Energy saving lamps have high luminous efficacy more lumens per watt.
Lumens are the overall light output or quantity of light produced and a watt of course is a unit of power that is used to measure the power consumption of a lamp.
Linmore led labs begins by working with leading diode manufactures that create superior lumens watt offerings.

Because lumens measure brightness and watts measure energy output there is no simple method for converting wattage to lumens.
With energy efficient lighting like leds and cfls how many lumens are in a 60w bulb or 100w bulb depends on the lumen output of the bulb not its energy use.
Here s a wattage equivalence chart but note that lumen per watt ratios can range mildly even from led to led products.
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.
Energy saving lamps have high luminous efficacy more lumens per watt.

As lighting becomes more and more energy efficient the same number of lumens is being achieved with lower and lower wattages.
On the low end replace a 40 watt bulb with an energy saving bulb of about 450 lumens.
Many different models and styles of led bulbs are available in today s marketplace.
When choosing a bulb keep in mind the following.
Compare lumens to watts.
Lumen is the term used to describe the total amount of light emitted by a light source while wattage merely indicates the amount of energy it uses.
Cfls and leds use much fewer watts than incandescents with the same brightness.
Read the package to choose desired illumination level.
For example a 3w led is equivalent in output to a 45 w incandescent.
Rely on new bulb labeling standards to show lumen output and help you choose the.
As a rule you ll replace a standard 75 watt bulb with an energy saving bulb of about 1100 lumens.
Simply the more lumens you can get from a watt the more efficient the lamp is at doing its job.
