** Note electricity rate @ .12 ₵ per KWH
** This Calculator will work for lights or any appliance in your house 
(ignore the CFL & LED cost comparison for appliance calculating)

1) Enter Hours of use per day (average is 6hr)
2)
Enter Watts per Light (Watts = Volts x Amps)
3)
Enter Number of Days used
4)
Enter Number of bulbs (Default is one)

Example: 
A 60 watt light bulbs on for 6 hours used for 30 days. Your electricity rate is 12 cents per KWH.
The charge for this consumption of electricity

 Can an LED be used in an enclosed fixture?
my info source for article  by salanthousewatch@gmail.com
Yes, but only some brands and/or types
The issue is the amount of heat that can build up in the enclosed fixture.
LED bulbs are very sensitive to heat Enclosed fixtures will shorten the life of an LED
Testing of LED lamps occurs with  100° open fixture, but a closed fixture will well exceed 140°
The main factors that shorten life of LED are cheap or plastic capacitors & a poorly design 
of heat sinks that draw the heat away from light 
Consider where you'd like to place your LED bulbs.
If you have fully or semi-enclosed fixtures, look for LEDs that are approved for recessed or enclosed spaces.
 Another thing I found was that turning LED's on and off does not effect the life of bulb

Some A19 LED packaging says “Full Light Distribution,” “360 Light  All-Around” 
Is this important?
Yes. It means that the light-emitted bulb is “omnidirectional” — it goes in all directions
and the bulb can be used for both general lighting and task lighting.
The old incandescent were all omnidirectional.
Most of the A19 LED's have this feature, so you have to check the packaging.
When an A19 LED is not omnidirectional, the light only goes up,
illuminating a smaller area.
This type of LED, which generally costs less, works well for creating
“atmosphere” but it’s unsatisfactory for reading and other close work.
