Why don U-Tron LED lamps use lenses?
Other manufacturers of LED lamps use lenses to direct the LED light output over the area to be illuminated. However lenses have a number of disadvantages: lenses are expensive to produce, a lens absorbs up to 20% of the light output by an LED and lenses get dirty, thus further reducing the usable light. U-Tron uses its patented “reflective cup” technology to produce an even distribution of light from the LEDs in a luminary. Reflective cups are cheaper to produce than lenses, they do not absorb light and produce an even light distribution as effectively, or more effectively, than lenses.
