Seasonal LEDs

Eco-Chic's picture

SLEDs (Seasonal Light Emitting Diodes) are great replacement seasonal lights to your regular incandescent lights. SLEDs are made from tiny solid-state chips that are similar to those used in computers. These chips convert electricity directly into light without the need of a filament or glass bulb, as it is required with incandescent lights. SLEDs use a solid plastic that is virtually unbreakable, and can be made into a variety of shapes, sizes and colours.

Below are some facts regarding seasonal LEDs:
-SLEDs are very energy efficient, thus are environmentally friendly. An individual SLED string of 70 lights consumes about 3.22 watts, as compared to an incandescent string of 70 lights that consume 350 watts. Each LED bulb consumes 0.046 watts.
-One single C-9 incandescent light bulb consumes 7 watts, enough to power over 140 LED bulbs. That is almost two 24-foot strings of LEDs.
-SLEDs last at least seven times longer than incandescent lights (about 20 years).
-Because SLEDs are made with solid flameproof epoxy plastic, they are virtually unbreakable and do not produce heat, reducing the risk of fire and are safer to use both indoors and out.
-SLEDs cost more to purchase than incandescent lights but they will last much longer and use less electricity, which makes them less expensive to operate. They will eventually pay for themselves.
-SLEDs use approximately 95% less electricity than incandescent holiday lights. The following shows the cost savings: ($0.10 was used as an example; insert your electricity costs to figure your seasonal costs)

SLEDs

4 strings (25 bulbs per string) = 100 bulbs
100 bulbs, each consuming 5 watts = 500 Watts
500 Watts x 5 hours per day = 2500 Wh
2500 Wh x 31 days = 77,500 Wh, or 77.5 kWh (kilowatt hrs)
77.5 kWh at 10 cents per kWh = $7.75 per season

4 strings (70 bulbs per string, to give equivalent light output) = 280 bulbs280 bulbs, each consuming .046 watts = 12.88 Watts
12.88 Wh x 5 hours per day = 64.4 Wh
64.4 Wh x 31 days = 1996.4 Wh, or 1.9964 kWh (kilowatt hrs)
2 kWh at 10 cents per kWh = $ .20 per season

There have been many questions regarding the use of SLEDs, such as the cost difference between one colour than another, and the issues regarding no
replacement bulbs. Below are common questions (and answers) regarding SLEDs.

-Colour Price: Reasons for the difference in prices for one colour versus another is because of the manufacturing costs: different coloured LEDs cost more to manufacture than others. For example, red, green and yellow are the cheapest to make than blue and white.

-Non-Replacement Bulbs: There are three reasons why there are non-replacement bulbs for SLEDs:

  1. SLEDs are polarity specific, like a plug. Reinserting a bulb the wrong way will result in an inoperative bulb.
  2. Each LED colour requires a certain amount of power in order to work at its highest efficiency. For example, if a blue LED is replaced with a red LED,
    the bulb will eventually burn out because of the wiring: a blue LED socket is wired to produce more power than needed for a red LED.
  3. Any moisture that comes in contact with the bulb or any other wiring part will cause the bulb to rust, causing the bulb to fall out of the socket within a
    few months. LED string bulbs are watertight to prevent any moisture from entering the area of the connection.
