What is meant by "Beam Pattern"?
Our lights come in 3 different configurations: Spot, Flood, or a combination of both.
A spot beam produces a cone of light in a narrow 8 - 10 degree spread (depending on the exact light). This is good for specific task type lighting, or additional visibility when driving at night.
A flood beam produces a cone of light in a wide 90 degree spread. This is good for general work lighting, lighting up an off road trail that may have overhead tree limbs that you want to see, etc.
A combination combines these both. They have lights on the outside of the bar that produce a flood pattern while the inner lights produce a spot pattern. These are a great overall light with a lot of versatility and are our best selling lights for that reason.
That said, we normally recommend and mostly stock the combo pattern. Why? Because these lights offer the greatest versatility. Due to their small size, the pods only come in either spot or flood, not combo. The spots produce enough light spread that they seem to be more effective and a better all around light, and as such we carry mostly the spot configuration of the pods.
