I've installed many of these mini lightbars, and they are very bright.

I got a Centurion on my paid dept's frontline engine and we have a spare that was donated. The one on the engine is gonna be replaced with an LED bar soon, but we're moving it to our heavy rescue. The Centurion puts out the best light output IMO compared to any other halogen bar and the size of the rotators helps. I believe the Guardian and Centurion rotators are the same.

countryboy1365 said:some one please correct me if im wrong but wouldn't the light output and beam pattern be slightly less on a filter and lens combo as the beam would have to pass through 2 pieces of plastic vs one? Im sure it would be only a slight difference but it makes you wonder.

Only the dimmest and least eye-catching strobes ever made. The European versions may be better, but most American Vista strobe lightbars like that were terribly dim. The halogen rotator version, on the other hand, was very bright and effective.FGS said:On an off topic. Anyone know whether the blues on the Tennessee State Trooper are halogen flashers, steady burns, or strobes?
It's not that colored lenses make LEDs actually produce brighter light - they don't. What I think happens is that when sun is shining on a light with a clear lens, the light gets reflected off (just like any other surface) and since the clear lens doesn't filter out any light, that's a lot of light being reflected. With a colored lens, a lot of the light is filtered out, so it appears darker. When the light is actually turned on is when this becomes much more significant - the increased amount of light being reflected from a light with a clear lens interferes with the colored light produced by the LEDs, and the perceived difference in brightness between the "on" and "off" periods is decreased. With a colored lens, less light is reflected, so this effect is diminished, and so the light appears brighter. At night when there isn't any light to reflect off a clear or colored lens, this is a total non-issue and the lights will be of nearly equal brightness.JohnMarcson said:Yeah... I love love the pseudo science online.... hazed lens doesn't effect some lights... colored filters make colored LEDs put out MORE light....
