From what I have heard. The biggest problem with LED lights is the moisture leaks in. I just now purchased 4 4" LEDS for the sides of rack on my truck and it says these are waterproof. We will see. I guess the cure is pretty easy. Just silicone around the glass and where the case splits. I think unless you spend several hundred $$ you are kind of stuck in the cheap o zone. Then I see rigid lights are the preferred brand
I had Rigids on my my Gobi roof rack for a long time. They're fantastic. I'm probably moving them to the Commander project if I don't sell them with the roof rack.
I also have VisionX lights, and many people in my SAR unit have them. They are also great lights.
The VisionX seem to be brighter and a bit better focused, and the Rigids seem to be a little more durable (Though, I haven't broken, or seen either brand broken). Both are completely waterproof and take a beating and have great electronics, optics, and heat sinks. Both companies have fantastic support and are guaranteed for 50k hours
Probably late to this thread, but I have 8" LEDs on the sides and rear of my rig, with PIA old schools for driving. I like the look and ease of the LEDs but I find the light falloff to be too shallow. Meaning, the light does not project as far as a lensed light. They are definitely bright at the source, but....
On that it depends on the degree pattern of the reflector. I have both 30 and 60 degree lights, and the 30s (spot beam) reach out further than the 60s (flood) do.
I have a new light bar on the way that is classified as a ultra spot (5 degree) and I'm hoping that takes care of my distance issues. I have some piaa 525s and I cannot see them with my unknown brand curved bar
