8W06T8SW 8W T8 LED TUBE 0.6M 4000K

Scenario

• Radio Parts has approximately 500 fluoro tubes [item 25582495] in current use.
• Current cost of power is 0.152¢ per kWh [3 phase]
• We will start replacing these with LED tubes [25600110]

Workings

• The Doss T8 is rated at 16W as opposed to the 36W ofa standard T8 fluorescent tube
• Using a Fluke 771F we confirmed the current draw
• By roughly adding the material, labour and power costs, we investigated costs over a 25 year period

Assumptions

• Cost of LEDs are reducing in price over time, but we are assuming that prices remain the same
• Usage is based on 8 hours per day for 365 days a year
• Energy costs are likely to increase over time, but we are assuming energy prices remain fixed
• The assumed install price is the same. Though LEDs involve the removal of the starter and ballast, the fluoros are hotter (cannot be touched) and are more fragile

Conclusion

• For our existing site, it's nearly cost neutral forthe first 2-3 years. After 25 years, we expect to save over $80,000
