| Sr No | Discription | LEDs | Incandescent Bulb | CFLs |
|---|---|---|---|---|
| (A) | Energy Efficiency & Energy Costs | |||
| 1 | Life Span (average) | 50,000 Hrs | 1200 Hrs | 8000 Hrs |
| (B) | Watts of electricity used (equivalent to 60 watt bulb) | |||
| 1 | LEDs use less power(watts) per unit of light generated (lumens). LEDs help reduce greenhouse gas emissions from power plants and lower electric bills | 6 – 8 watts | 60 watts | 13-15 watts |
| 2 | Kilo-watts of Electricity used (30 Incandescent Bulbs per year equivalent) | 329 KWh/yr. | 3285 KWh/yr. | 767 KWh/yr. |
| 2 | Annual Operating Cost (30 Incandescent Bulbs per year equivalent) | $32.85/year | $328.59/year | $76.65/year |
| (C) | Environmental Impact | |||
| 1 | Contains the TOXIC Mercury | No | No | Yes – Mercury is very toxic to your health and the environment |
| 2 | RoHS Compliant | Yes | Yes | No – contains 1mg-5mg of Mercury and is a major risk to the environment |
| 3 | Lower energy consumption decreases: CO2 emissions, sulfur oxide, and high-level nuclear waste. | 451 pounds/year | 4500 pounds/year | 1051 pounds/year |
| (C) | Important Facts | |||
| 1 | Sensitivity to low temperatures | None | Some | Yes – may not work under negative 10 degrees Fahrenheit or over 120 degrees Fahrenheit |
| 2 | Sensitive to humidity | No | Some | Yes |
| 3 | On/off Cycling (Switching a CFL on/off quickly, in a closet for instance, may decrease the lifespan of the bulb.) | No Effect | Some | Yes – can reduce lifespan drastically |
| 3 | Turns on instantly | Yes | Yes | No – takes time to warm up |
| 3 | Durability | Very Durable – LEDs can handle jarring and bumping | Not Very Durable – glass or filament can break easily | Not Very Durable – glass can break easily |
| 3 | Heat Emitted | 3.4 btu’s/hour | 85 btu’s/hour | 30 btu’s/hour |
| 3 | Failure Modes | Not typical | Some | Yes – may catch on fire, smoke, or omit an odor |
