- Note: the plastic components can not.
- Avoid Toxicity
- Paint is water based paint

People / Community Wellbeing
- Ergonomics - lighting as if the planet and humans matter
- Head rotates 360 degrees
- 3-point adjustability
- Built-in 4-step dimmer...level needed

- Color Temperature: Natural 5,000K or Warm -- 3500 K

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).
