So, based on the "lipstick on a pig" rule, DigiTails' website use of "Extra bright" language language in their advertising makes me think that they might not be as bright as they should be? After all, when was last time you bought at 1157 tungsten bulb and saw on the package that it was "extra bright!"
Call me skeptical, but DIGITAILS Website conveniently neglects to post the lumen number under their "specifications" section. Why? I would ask the salesman to define in specific engineering units (lumens, foot candles, or LUX) the light output of the LED panel IN application.
