LED lighting products are gaining popularity among common people these days also the chances of choosing an undesirable product is more than ever. For choosing a desirable product, the following FAQs will be useful.
1. Choose higher lumen: Don't compare the power of the luminaries compare the lumen output. This will help you achieve more performance in same power compared to the luminary having less lumen output, sometimes you can reduce the no. of luminaries also.Different make of LED luminaries having same power may deliver different lumen outputs
2. Efficiency> 85%: LED Driver: choose a driver with higher efficiency. We need at least 85% efficiency to achieve the power savings offered by the LED technology.
Which means a costlier LED luminary with lower efficiency driver may consume the same power of standard fluorescent luminary having higher efficiency driver. How ever higher the efficiency higher will be the cost of the luminary.
3. Power factor>0.9 : Power factor of the LED driver should be greater than 0.9 and THD< 15 to avoid more loading on the electrical grid and on your generators or inverters. With higher power factor you can connect more load to the existing generator or inverter compared to a lower PF one.
