Latest LED lighting facts by DOE

The DOE’s Lighting Facts program recently recently released a report and tracked that LED luminaires are competing with their traditional counterparts in many applications, at least in the highest-performing products.

I too feel that in India Commercial outdoor luminaires — including area and roadway, parking garage, Street lights etc — are getting more efficient. Also in recent times it is seen in India that the municipalities, utilities, and retailers that typically use these devices are willing to pay up for them because these applications have high baseline wattages and long hours of daily use.

The efficacy of LED outdoor luminaires varies considerably, but many of them surpass the efficacy of MH and HPS systems (which can range from 45 to 75 lm/W), with the highest LED efficacy levels approaching 100 lm/W. In terms of color quality, DOE says most LED outdoor luminaires have CRIs that exceed those of MH (CRI typically 65) and HPS (CRI typically 20) systems and range in CCT from 4,000 K to 7,000 K, which is cooler white light than traditional fixtures (2,000 K to 6,000 K).

For those who aren’t fans of CFLs : DOE says the majority of LED recessed downlights meet or exceed the light output levels of their incumbent CFL counterparts. The efficacy of LED downlights varies a great deal (from 11 to 80 lm/W), but the average (45 lm/W) exceeds average CFL benchmark levels (35 lm/W).

However the real mix of success  in LED lighting, I personally believe would only come to companies able to excel in the optics, electronics, and overall development that will let fixtures fit into applications like a glove. The key lies very much into the efficient fixture designs for the glowing future of LED lighting……..
