Light Emitting Diode (LED) manufacturers sort their products into “bins” based on forward voltage, with the purpose of delivering the most consistent light possible. Despite the tight grouping of forward voltages in these bins, manufacturing tolerances continue to lead to significant variations in both current draw and temperatures inside the LEDs, resulting in a range of colors, even within the same batch.

Retailers Light up the Holidays with LEDs

Jay Black, VP of Development & Communications

‘Tis the season for festive lighting, longer store hours and everyone’s favorite, costly energy bills. Retailers know this struggle all too well as the combination of extra lighting displays and energy needed to keep stores open longer often results in added energy costs building up between the months of November and January. The holidays can put a damper on energy expenses but it is possible for retail facility managers to cut costs while keeping stores ‘merry and bright’ with the help of solid-state LED lighting solutions. We’ve seen LEDs take over the holiday light sections with strands of colorful LED lights giving off a brighter glow, but where the real energy savings come from is a store’s overhead lighting, and LEDs offer the best solution for reducing energy costs.
