The E-Series lineup of products by Rigid Industries set the standard in forward projecting LED lights in 2004. The original patented Hybrid optical system continues to lead the field in efficiency and projection. In 2011 Rigid Industries reinvested and redesigned the original Hybrid system to work with the latest Cree and Osram LEDs. This redesign netted an almost 50% increase in center intensity over the first generation optical system. Using the new optical system, current E-Series lights project more than twice the amount of light at the same power. As LED technology evolves, so does the ageless E-Series product line.
