About PowerDiscTM: converts AC to DC power…
By converting to DC power, this significantly reduces energy consumption and maintenance costs as well as extends bulb life up to one hundred times. It consists of a nylon reinforced thermoset plastic disc, a solid-state rectifying diode and a foam washer with an adhesive surface. The PowerDiscTM is attached to the base of a light bulb by means of the 3M adhesive coated foam so that the center contact of the bulb is in contact with one end of the diode. When screwed into a light socket, the other end of the diode contacts the center contact of the light socket.
The PowerDiscTM is UL tested and listed!
Your Incandescent Light Bulb will now last 10+ years!!!*
Once contact is established and power applied only the positive waves of current may pass through the lamp filament while the negative-going waves of current are blocked. In other words, 120 volts of alternating current (AC) are rectified or converted to approximately 85 volts of pulsating direct current (DC). The light bulb filaments, that actually create the light we see, will burn at a much cooler temperature on pulsating DC as opposed to AC power. The degree to which the filament is heated is directly related to the life of the bulb. Thus, a 100-watt bulb with a standard life of 1000 hours (41 days running continuously) will now burn for up to 100,000 hours, or 24 hours a day for 11-1/2 years running continuously, over 10+ years with normal use. To achieve maximum life-extension the PowerDiscTM MUST be used with a brand-new halogen or incandescent bulb.**
See Figure #1: THE GENERAL ELECTRIC INCANDESCENT BULB LIFE EXTENSION CALCULATION
To determine the life extension of a 100 watt A-19 bulb, let’s assume the life expectancy of a 100 watt A-19 bulb is 750 hours. Let’s assume the PowerDiscTM reduces the standard line voltage from 120V to 85V.
By using the formula from the General Electric Incandescent Lamps Booklet (ref. GE #TP-1100R2 5/84) we calculate the life of the bulb with the reduced voltage.
The PowerDiscTM can be used from your medium-based chandelier and up to your 350 watt flood lights!
Energy consumption is reduced approximately 42%
A 100-watt bulb will now operate at 58 watts with PowerDiscTM, thus reducing energy consumption. However, light output is reduced. If it is important to maintain the visible light level, a higher wattage bulb should be used. Although overall energy savings are reduced with the higher wattage bulb, extended bulb life remains the same, virtually eliminating bulb replacement and the maintenance costs associated with changing bulbs. In fact, as bulb wattage increases, efficiency in the transformation of electricity to light also increases. The PowerDiscTM is designed to work on 60-cycle AC current.
The PowerDiscTM has an 8-year product replacement warranty*** The actual extended life of the bulb is dependent on the original life rating of the bulb.
Ex. 1000 hours is now 100,000 hours! **To qualify for the warranty, a brand new incandescent or halogen bulb which has a minimum life rating of 750 hours must be used with the PowerDiscTM
