Traditional Lighting is not efficient. The challenge is to replace with more efficient lighting. LED offers at least 50% savings with a payback of less than 1 year. For 24×7 operation, this means positive cash flow after one year, less maintenance, brighter light with no UV or hazardous material. Not all LED tubes are the same. Gemwel offers Flicker-free Industrial grade with 3 years warranty; thus replacing with peace of mind.
