Wattage
Used to measure LED
light bulb power consumption.
Lumens describe the
''brightness'' of a led light, "wattage" describes the power it takes
(on your utility bill) to drive that led lamp.
In general, however, a higher
wattage lamp will normally produce more light (more lumens) than a
lower wattage lamp
OF THE SAME TYPE. The unit for measuring electrical power. It defines
the rate of energy consumption by an electrical device when it is in
operation.The energy cost of operating an electrical device is
calculated as its wattage times the hours of use. In single-phase
circuits, it is related to volts and amps by the formula: Volts x Amps
x PowerFactor = Watts.
LED's use about 1/5
of the energy of their equivalent incandescent flood replacement and
1/2 of their equivalent compact fluorescent (CFL) replacement.
Please note:LEDs
have a lumen to watts rating
LED bulbs: 70-80lm/W
CFL bulbs:50-70lm/W
Incandescent
bulb:5-6lm/W
Lumens
The measurement of
that light energy is the lumen (lm). Simply put: lumens are the measure
of the total light output we see. This 'brightness' is now required to
be listed on light bulb packaging. Lower numbers are duller and higher
numbers are brighter.
When purchasing
light bulbs the best measure to determine suitability is the lumen.
LEDs have a lumen
to watts rating that far surpass incandescent bulbs and even have
better ratings that compact fluorescent bulbs (CFLs).This means that an
LED light will cost you less in electricity and still shine bright.
Lux
Typically used to
measure the light intensity produced by a lighting fixture. The higher
the lux reading the more light the lighting fixture is producing over a
given area. Known as lumens per square meter.
