UV Lamp Replacement Cost with number of lamps in this swap of 10 lamps: a worked example

Push number of lamps in this swap up to 10 lamps and the picture changes. This example computes every intermediate figure at that operating point. Use it when comparing OEM vs aftermarket lamps, when quoting cure-intensive jobs, or when justifying a tighter PM cadence to operations.

The inputs for this scenario

  • Number of lamps in this swap: 10 lamps (raised for this scenario; the documented default is 4)
  • Unit price per lamp: 650 $ / lamp (unchanged)
  • Downtime cost during the swap: 450 $ (unchanged)
  • Scrap / rework risk allowance: 200 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Lamp material cost = lamps × unit price) to the inputs above produces each figure below.
  • At this operating point the engine returns 7,150 $ / lamp swap for true cost per swap, the number this scenario is built around.
  • At this operating point the engine returns 715 $ / lamp for cost per lamp.
  • At this operating point the engine returns 6,500 $ for lamp material cost.
  • At this operating point the engine returns 650 $ for downtime + scrap risk.

How this compares with the baseline

  • Against the tool's baseline example, where number of lamps in this swap sits at 4 lamps and the headline result is 3,250 $ / lamp swap, this scenario comes in 120% above the baseline at 7,150 $ / lamp swap.
  • It sums lamp material cost, downtime cost, and scrap/rework risk into a true cost per swap and divides by lamp count for cost per lamp. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • True cost per swap: 7,150 $ / lamp swap (headline result)
  • Cost per lamp: 715 $ / lamp
  • Lamp material cost: 6,500 $
  • Downtime + scrap risk: 650 $
