A 50-cent, 60-watt incandescent bulb will use about $6.60 in electricity every year.
Switch's 60-watt-equivalent LED, meanwhile, uses only 13 watts of power, so it will cost only $1.43 per year.
The Switch bulb also has an average lifespan of 20,000 hours—20 years. If you count the price of replacing the incandescent bulb every year, the Switch bulb will have saved you money by its fourth year.
Over 20 years, you'll have spent a total of about $142 for the incandescent bulbs (for electricity and replacement bulbs) and less than $50 for Switch's 60-watt bulb.
In 2 years, a $10 cost would have a payback of 2 years for energy savings and lack of replacement to make the new LED the better buy.
The color of the light matches and the size and shape are as before.
* Replacement lamp design relies on inert liquid for cooling allowing Switch Lighting to drive the LEDs at higher current achieving greater brightness with fewer components.
* The lamps have a 2750K warm-white color temperature and a CRI of 85. The lamps are rated for 18 years of life based on three hours of usage per day. Switch claims the 75W replacement lamp will deliver $140 in energy savings over the life of the product relative to a 75W incandescent.
