Heavy duty LED work lights are designed to deliver the brightest white light under harsh operating conditions. They need to be tough because, depending on where they are installed, LED work lights will to have endure any of the following:
– salt water,
– high temperatures,
– freezing cold temperatures,
– deluging rain,
– repeated jolting,
– and in some settings, such as the mining industry, they operate 24 hours a day.
So let's ask:
Why are LED work lights such a brilliant idea?
Okay, I admit it. That's a bit of pun, but it's also true. LEDs produce high intensity, brilliant light. How's that? Because an LED is a special type of electrical component (called a diode) which allows electricity to flow through it in such a way as to generate light. LEDs make light electronically which means they don't get hot and they also use significantly less electricity. And as I was saying a moment ago, the light which they give off is ultra bright.
Contrast them with incandescent lamps. Most of the electricity they eat up is used to generate heat (not light) which is why conventional globes are hot to touch after they've been on for a little while.
Not so with LEDs. Most of the power they eat is used to produce light. They are 400 per cent more energy efficient.
But that is not the only feature which makes them so attractive.
LED technology does not use a filament, so LED lamps can handle the bumps and thumps that industrial and heavy commercial usage often involves. Not having a fine filament means these units are tough. They can take a lot of punishment and they're hard to break.
REDUNDANCY IS BUILT IN
Also, redundancy is built right into the design, because most LED lamps contain multiple diodes. If one does happen to fail (a rare event!), There are other light sources in that housing and these will to continue to blaze powerfully.
VOLTAGE SPIKE PROTECTION IS BUILT IN
Sophisticated LED light bars use PWM (that's Pulse Width Modulation) to control the current. PWM turns the LED on and off at a controlled rate which is so fast it is measured in milliseconds. There is no flickering effect because the on / off rate is well above anything the human eye can detect.
As a result, there is one invisible benefit which this system delivers – and that is protection against voltage spikes from the vehicle's electrical systems.
Now let's ask:
What industries require heavy duty LED work lights?
Actually it's a surprising number of situations that call for superior illumination. Here are just a few.
– Earth moving. Such as excavators, bulldozers where the entire machine is subjected to frequent and substantial impacts.
– Forestry. Think of logging vehicles crashing their way through uneven terrain.
– Marine. Any water craft, from the large passenger cruisers to small fishing boats, can be subjected to extremes of weather with little advance notice. Plus, for ocean going vessels, there is the corrosive effect of salt.
– Recreational vehicles (RVs). Off-road vehicles in particular get a solid pounding and their lighting systems need to be rugged.
– Trucks. Such as tow trucks and pickup trucks.
