Not in here to start a vendor war but based on these results I doubt that a 10w light outputs same as our 240w 40" lightbar.
You'll have to speak with @
KaiserM715. He was a neutral party that conducted all testing.
As far as our light that was tested, allow me to clarify. We refer to our Apollo4 10w as the 10watt version. That being said, each LED chip in the light is a 10 watt chip. So the total power draw of the light is 40 watts.
We offer our Apollo4 in a 3 watt, 5 watt, and 10 watt version. The 3 watt (16w total) version is reserved for our amber lights, while the 5 watt (20w total) and 10 watt (40w total) versions are white lights. All versions are available in a spot, flood, or diffused beam pattern.
