In your quest to upgrade the lighting on your off-road vehicle, most will encounter confusion and frustration. These emotions are often brought on by the myriad of both brand and industry specific terms used to measure brightness, types of lighting, measurement, and purpose. For example, some companies may discuss the brightness of their lights by using lumens, lux, or even effective lumens. Going even further their measurements may not even be taken using the same methods and tests. For example, one company may use one distance to measure the effective brightness of their lights while another company uses a completely different distance, dissimilar mounting position…or an entirely offbeat testing method. As a consumer, you need to educate yourself in order to find the perfect off road lighting solution for you. With that in mind, the crew here at Drops Mobile would like to help you make a wise and informed decision.


Uses For Off Road Lighting

Aside from looking cool on your lifted truck or Jeep, off road lighting has quite the number of practical applications. If you’re looking for an off road lighting solution, you may already have a couple of these practical applications in mind.

Added Illumination For Off Road Driving-When off the beaten path, a higher number of obstacles often exist. A solid lighting solution will help you to see these obstacles before they become a problem.

Yard Clean Up-Most off-road vehicle owners are hard working folks that don’t stop when the sun goes down, flip a switch on your truck and you can extend your work day so that the job gets done!

Field Parties-Like a country song, owning an off-road vehicle means that you work hard and play harder. Keep the good times going with a little light from your truck.

Safety-We’ve all driven in foul weather, a little extra illumination often increases the safety factor and gets you to your destination.


Measuring Illumination For Off Road Lighting

Like I mentioned above, most off road lighting companies measure the brightness of their lights using either Lumen, Lux, or Effective Lumens. While measuring them against each other will get you an “apples to oranges” comparison most often, understanding exactly what each unit of measurement is can give you a decent base point for comparing off-road lighting solutions.



According to Merriam-Webster, a Lumen is “a unit of luminous flux equal to the light emitted in a unit solid angle by a uniform point source of one candle intensity”. While this definition in itself doesn’t help most of us when shopping for off road lighting perhaps a comparison can. For example, a 23-watt spiral “green bulb” that most of us are using in our household lamps emits about 1100-1400 lumens. While that may be bright enough to light up the living room, we may want a little more to light up the wilderness that lies ahead of our off-road vehicle. Most Cree LED light bars are in the range of 18000-24000 Lumens.



LUX is another method of measuring illumination and is actually based off of the Lumen. Once again we’ll consult the Merriam-Webster dictionary for the definition. LUX is defined as “the SI unit of illuminance, equal to one lumen per square meter”. See what I mean? It is based on the Lumen! While not as commonly used as the Lumen, it is important to understand what LUX range most off road lighting units come in. For example, a 9” circular light will usually have illumination between 2000 and 2500 LUX for spot and 600-900 LUX for flood.


Effective Lumens

Another common measurement of illumination is the effective lumen. Where the raw lumen is a simple measurement of math…say we have 10 bulbs that are 100 lumens each we have a raw lumen of 1000, simple right? What the raw lumen doesn’t take into account are certain “real world” considerations that can reduce that number by up to 75%. Factors such as mounting position, the shape of the light cluster, and power being provided to the light can all play a factor in reducing the raw lumen measurement. It is for this reason why we have the measurement of the effective lumen. Measuring effective lumens requires the use of high-tech photometry equipment, which is why most manufacturers opt to advertise the raw lumen rating of their lighting solutions. Absent this equipment to check out the actual illumination of the lighting solution you are shopping for, using product reviews, and word of mouth advice goes a long way in selecting the right lighting solution for your off-road adventures.


Color Spectrum

The final measurement of off-road lighting we will discuss is the color spectrum. Simply put, it is the “color” of your lighting output. Measured in Kelvin or K, it ranges generally from 1000-10000. At the lower end of the spectrum is the “warmer” colors, for example, the orange/yellow of a candle sits at 1900k and the blue sky sits at 10,000K and above. As a general rule, LED lighting sits between 2700K and 7000k.
