Service life

Years in service. The band runs from the shortest to the longest life the sources state, so it shows how much they disagree, not how long 80% of units last. The line is the median of the stated lives.

Work out when yours is due for replacement

Basis

• 25–30 years · CNA e-Tool Estimated Useful Life Table, p14 · HUD CNA 3.4.4.3.3 “Lighting- interior common space” — U.S. Department of Housing and Urban Development (planning life)
  Family properties 25 years, elderly 30. US multifamily housing. HUD's row is interior common-space lighting and does not name the lamp technology.
• 15 years · Purchasing Energy-Efficient Commercial and Industrial LED Luminaires (web page, modified 2025-10-30) · Table 2 assumptions “"Lifetime Energy Cost: Calculated as the sum of the discounted value of the annual energy cost and assumed product life of 15 years."” — U.S. Department of Energy, Federal Energy Management Program (planning life)
  Interior commercial/industrial LED luminaires (example: 2-ft. x 4-ft. LED troffer at 3,600 h/yr). Assumed life for life-cycle cost; fixture type and operating hours stated, no other basis given.

Open questions

• HUD's row is interior common-space lighting in general and does not name the technology; LED drivers and modules often fail before the fixture body. A source specific to LED fixtures is needed.
• Every source here is a published planning, design or accounting life. None is observed replacement data.
