Based on an average incandescent bulb life of three months, converting to PowerLine® LEDs will pay for itself in material costs alone within the first year. This payback period takes into account only the cost of the incandescent bulb. It does not take into account the labor cost associated with changing bulbs, power savings, operating downtime, incandescent bulb inventory and ordering costs, and other significant factors.
The following graph depicts the average cost of replacing a $3.25 1835 incandescent bulb in one socket four times a year. The cost of the bi-polar 1835LS2 is fixed at $11.00 for ten years. For a facility with only 1,000 lamps, the material savings alone would be approximately $2,000 after the first year!
