In a previous
article, we have discussed some of the key technical terminologies you must
know so it will be much easier for you to identify the best and most suitable LED light bars for your vehicle. In
this article, we bring you more important terms to discover to help you find
the auxiliary lighting equipment you need.
Lumens
A lumen
measures the total amount of light emitted by a light source, or in this case,
an LED light bar. It tells you how bright and intense the light is and it is
what most people consider when shopping for LED lighting devices. The higher
the lumens are, the brighter a light bar is. Take note, however, that lumens do
not describe the quality of light a particular light source generates. You will
need to refer to the device's colour temperature for that.
Watts
Watts measure
electric power. They basically refer to the power consumption of any tool or
appliance that uses electricity. The higher the wattage is, the more energy it
requires to operate a particular tool, equipment, or device. When it comes to a
LED light bar in Australia, it is
always advisable to get one with a higher wattage. It is because the higher the
number of its wattage is, the more light it will produce.
Lux
Lux, or
illuminance, is the amount of lumens (luminous flux) received at a surface per
unit area. Simply put, it measures the amount of light that falls on a
particular place or area. Lux depends on the distance of the light source from the
area that is being illuminated and the angle of illumination.
PMMA
Certain LED bar light 4wd and
auxiliary lighting devices describes themselves as using PMMA technology, but
what exactly is it? PMMA stands for Polymethyl Methacrylate, which basically
refers to acrylic or acrylic glass. It is a transparent thermoplastic often
used as an alternative to light bar lenses made of glass because of its light
weight and shatter-resistant qualities. It is also a much cheaper alternative
to polycarbonate or PC lens, especially when extreme strength is not required.
Heat sink
LED light
bulbs also generate heat and if they are not dispersed properly, it can shorten
their lifespan. This is why every LED light bar has a heat sink. A heat sink is
an environment or object that absorbs or helps disperse heat from the LEDs. How
the heat sink is fitted into device can affect the overall performance of the
best LED light bar 4x4
so it would be wise to take this matter into consideration.
