That's the LED version if Unitys' newest post light. They've been around for ±5 years now.
More lumens than the orig incan 85w but nowhere near the throw. Longer lifespan is a big plus. LED is wall of light after 50', incan can throw ½ mile.
Was just rereading this, and you said you tested them 4 years ago, and LED is wall of light after 50 feet.
That does not make sense. If you tested 4 years ago, you likely tested the Whelen LED unit, I don't think Unity had their own spot yet, not till later in 2013. If you tested the Whelan 8 degree, ya that would be a wall of light at 50 feet, but the Whelen 2 degree is definitely not a wall of light at 50 feet by any measure. Not the throw of the Halogen, but no where near a wall of light.
You claimed the Incan can throw 1/2 a mile. No doubt a bit of hyperbole, but let's look at that. The Halogen at 1/2 mile (2640 feet), assuming 275K candela typical for the 85W HIR would be 0.42 lux on target. The Whelen, at 125K candela would be 0.42 at 1780 feet. Unity claims 215K candela for their unit, which would hit 0.42lux at 2330 feet. Sure the beam patterns would be different, but generally TIR optics LEDs have less spill, so their spots can often be more useful.
Your claim of wall of light after 50 feet makes me think you are were not looking at the narrow spots, but maybe the Whelen 8 degree. That would have appeared as a wall of light. The 2 degree is not going to appear as a wall of light, certainly not at 50 feet.
