What is a “Deutsch” connector?
Deutsch connectors are electrical connectors that are specifically designed for critical applications in harsh environments where dust, dirt, moisture, salt spray and rough terrain can contaminate and/or damage electrical connections.
What is the purpose of using a relay?
Using a relay keeps the high current portion of the circuit away from the switch and pulls the current directly from the battery to your lights. The relay also allows you to tie your lights into a secondary 12-volt circuit such as your high/low beams or ignition.
What's the difference Between Lux and Lumens?


What is it?:  Lumen is a unit of light measurement otherwise known as luminous flux.

We use lumens to compare the total amount of light output from a light emitter. However, lumens isn't everything. In fact, lumens will only tell you a small part of the picture to what you're actually getting and what you're after. We need to know how the lumens are used. Lumens is comparable to the analogy of a car's brake horsepower.

Lumens is measured using a highly specialized light integrating sphere.


What is it?:  Lux is a unit of light measurement taking area into account. In other words, light intensity. 

We use lux to measure the amount of light output in a given area. One lux is equal to one lumen per square meter. Lux is a good measurement for determining and comparing the brightness of a beam. The beam is spread over a specific area and therefore we use lux to measure light intensity. However, lux is just another number and doesn't provide the complete picture of what we're after. We need to know the beam angle and look at beam shots to fully understand the picture.

Lux is measured using a lux meter.

Beam Angle (FWHM)

What is it?:  Beam angle is the angle of which a light is emitted. More specifically, it is the Full Width at Half Maximum.

Since there is no real way to measure the 'edge' of light we measure the beam angle from where the light is at 50% intensity (FWHM). By being able to measure where 50% light intensity ends, it gives us the majority of where the light is used thus representing the beam angle. Smaller beam angles will have an intense hot spot, where as larger beam angles will have a lesser intensity (due to a larger area). Take a look at our beam shots and see if you can gauge where 50% intensity ends, giving you the beam angle.


What is it?:  Watt is a unit of power consumed.

More wattage produces more lumens. We can use wattage and lumens to measure efficiency of the light emitter. In the case of LEDs the efficiency is much higher than that of older halogen lights, producing significantly more lumens per watt. However, more power also means more heat is produced.

What is the regulatory standard “IP67”?

IP67 is just one of many Ingress Protection ratings. The IP Code outlines a system of classification for the protection of electrical enclosures against the intrusion of foreign bodies such as tools, dust, moisture, etc. IP67 specifically means that a light is dust proof and is protected from temporary immersion in water 1-meter deep for 30 minutes.

IP rating system:

A fixture's International Protection Rating specifies its ability to resist the ingress of solids (first digit) and liquids (second digit).  Please refer to the table below for specific levels of protection.



First Digit Second Digit


Protected against solid objects over 12mm (e.g. fingers) Protected against direct sprays up to 15 dg. from the vertical


Protected against solid objects over 2.5mm (e.g. tools and wires) Protected against direct sprays up to 60 dg. from the vertical


Protected against solid objects over 1mm (e.g. tools and small wires) Protected against sprays from all directions - limited ingress permitted


Protected against dust - limited ingress (no harmful deposits) Protected against low pressure jets of water from all directions - limited ingress permitted


Totally protected against dust Protected against strong jets of water e.g. for use on shipdecks - limited ingress permitted



Protected against the effects of temporary immersion between 15cm and 1m. Duration of test 30 minutes



Protected against long periods of immersion under pressure

Example - IP65:Totally protected against dust (first digit) and protected against low pressure jets of water from all directions - limited ingress permitted (second digit)
