Economic

  • Life Expectancy of Bulb
    • 40,000 hr lifespan (equivalent to 25 years!)...fewer bulbs to buy
  • Sharing
    • Will be a cart with lamps that can be checked out and returned when not needed.
  • Cost:
    • Initial Purchase: $135
    • Cost to Operate
      • Over LED Lamp Life Time: $32.50
    • Total Cost: $167.5
Comparison to 20W Staples Lamp

Cost: $29.99 .... say $30

  • Cost to Operate 40,000 hours:
    • Electricity: $100
    • Lamps: 20Watt GE Halogen Desk Lamp Bulb @ $5.99 each with 2,000 life + Shipping or Travel $4.00 = $9.99...say $10.
    • Numnber of Lamps to serve 40,000 hours = 20 lamps (40,000/2,000)
    • Lamp Cost = $200 for 40,000 hours

Total Life Cycle Cost = $330 over the life

Conclusion: Z-bar Mini LED Lamp is about one-half the life cycle cost ($167.50 vs. $330.00).
