Frequently Asked Questions (FAQs)

The PowerDisc™ is a sophisticated solid-state rectifier that converts 120 volts of alternating current (A.C.) to approximately 85 volts of direct current (D.C.). It mounts on the base, by way of 3M adhesive tape, to any standard incandescent or halogen light bulb up to 350 watts and is inserted into the socket with the bulb. The PowerDisc reduces the energy used by the bulb by 42%. It also proportionately reduces the heat produced by the bulb.
As it is well known in the industry, all energy efficient light bulbs will have some reduction in lumens (light output), initially up to 30% over the first couple of months. Take note of the packaging for CFL and LED bulbs, they claim they will operate at 70% efficacy - which means they know their bulbs will lose 30% in lumens. Example, the packaging states 1000 lumens but they "guarantee" that the bulb will operate at 700 lumens. Also the "long life" incandescent and halogen bulbs which operate at 130 volts, when you use it in a 120 volt socket, there is an immediate 25% lumen loss from what is stated on the packaging. Example, the packaging states 1000 lumens but in a 120V socket it is really 750 lumens. With the PowerDisc there is also an initial lumen loss, the difference is the bulb will maintain that lumen level for the life of the bulb- it won't get dimmer and dimmer over time until it burns out. If it is necessary to maintain similar lumen levels it is recommended to increase the wattage of the light bulb used. The lumen level of the light bulb is dependent upon the manufacturer, clear or frosted and type of light bulb being used. Also keep in mind the lumen level you have upon insertion will be the lumen level for the rest of the life of your bulb until the day it burns out, which means it does not diminish over time, whereas with CFLs and LEDs you get around a 30% lumen loss in the first couple of months, then it slowly decreases until it is very dim. This makes for safety and security issues in certain areas.
By achieving a 10+ year life extension of a bulb, the amount of natural resources that can be saved is staggering. Starting with the trees not needed for packaging, the gas to go to and from the store multiple times and the gas to go to and from the hazardous recycling center to dispose of the CFL bulbs. Then there is waste (paper towels, plastic bags, etc.) needed to clean up a mercury spill, a broken CFL. Additionally, the energy costs from the transport of a CFL to the special machine that has to break down and safely recycle the CFL bulb. If you haven't watched the video on our home page scroller of a clip from the TV "The Doctors", please watch and take note of how much waste and energy is needed to clean up ONE broken CFL bulb. Example, of course after you have evacuated the room and cleared it out for at least 15 minutes, when it "should" be safe to go back in, you will need a pair of rubber gloves, paper towels, cardboard, 2 large ZipLoc bags, duct tape and then when all of those contents are secure in your final ZipLoc bag you then get in your car and drive to the nearest Hazardous Material recycling center! Because as you know, in most states it is against the law to throw the CFL and its' clean up material in your home trash!!
Light bulbs generally burn out due to filament deterioration. By decreasing the applied power to the filament to a level far below the rated power of the bulb, the filament life is extended. According to Jack L. Lindsey’s Applied Illumination Engineering, the trade-off is a very good one, too. A very small decrease in voltage and lumens leads to a huge increase in life and a considerable decrease in energy usage (watts). Lowering the voltage only 8%, for example, leads to a 300% increase in life and nearly 15% decrease in energy usage with only a 25% loss in light output!
It extends the life of the bulb up to 100 times the rated life of the bulb. For example, a 1000 hour rated bulb will last 100,000 hours (11.5 years- burning 24/7) or more depending upon the hours used. So basically, to calculate, take your brand new bulb locate the stated life "hours" rating and multiple by 100. That will be the approximate life of your new bulb with the PowerDisc™.
Since there is no active circuitry, there is virtually nothing that should wear out. Therefore, the PowerDisc™ should outlast the life of the socket.
Yes, the PowerDisc™ is UL tested and listed.
The PowerDisc™ can be used with any medium base candelabra, incandescent or halogen bulbs up to 350 watts and 120 volts. The PowerDisc™ is not recommended for use with a 3-way bulb. It can be used with newer dimmer switches. This also includes outdoor security flood lights, no matter what the weather- freezing or scorching hot! Also, canned lights and enclosed fixtures have no effect on the performance of the PowerDisc™.
Commercial space can cost from $1.00 to $1.50 per square foot per month, at a, minimum. Most of a 4' X 8' storage area in a local office is devoted to lamp storage. This area, worth about $35.00 per month is charged indirectly to clients. For larger facilities this space can be very expensive. If lamp storage space could be reduced or eliminated, valuable, commercial footage could be employed in other more productive ways.
Arcing is a common occurrence in all electrical fixtures. It is NOT a result of using the PowerDisc™. A small percentage of lamps will become loose in the socket during operation. If a slight gap appears between the base of the bulb and the socket contact, an arc, a jump of electrical current - can occur. An arc produces brief, intense heat. This usually results in a lamp burn-out and, sometimes, will damage a socket beyond repair. In the worst case complete replacement of the socket, lamp and/or fixture is electrical "impact" of an arc in some lab and field experiences. By utilizing the PowerDisc the more expensive socket and fixture are protected from damage. Using the PowerDisc™ does not cause or prevent arcing, but if arcing does occur, the PowerDisc™ acts as a buffer, and absorbs the entire impact of the high amperage and voltage production. The foam adhesive on a PowerDisc™ keeps pressure on the bulb and retards its tendency to work loose in a socket.
The locations of many lighting fixtures pose hazards for the person changing burned out lamps. While exact figures are unavailable, it is obvious that ladder work can, and does, involve many fall injuries every year. Such a risk increases where non-professionals find themselves changing hard-to-get-at ceiling lamps or outdoor floodlights. Senior citizens and homeowners are not immune from the difficulty, risk and inconvenience of replacing spent lamps. Why encourage the potential hazard of unnecessary ladder work when lamps can actually last 11.5 years or longer without need for replacement? It seems obvious that injury liability can be reduced if a socket requires only one labor operation over eleven years instead of 100 such operations.
Many individuals believe that bulb maintenance costs are negligible. The true fact is that these costs to change a light bulb will vary from $1.00 per change to upwards of $30.00 per change. Factors that will determine the actual will be:
  • Union versus Non-Union Shop - If a ladder is required, unions necessitate two individuals. The first individual to hold the ladder while the second individual climbs up the ladder.
  • Locations of Bulb– If bulbs are located in hard to reach areas, many applications necessitate hydraulic trucks or scaffolding to be constructed in order to have access to bulbs.
  • Type of Labor Used- Depending on location, skilled labor (an electrician) as opposed to non-skilled labor may be required. It is obvious that an electrician will cost on an hourly basis considerably more than a non-electrician.
  • Type of Fixture- A fixture that has to be unassembled to have access to the bulb will require more time and thus higher cost for bulb replacement than one not having to be disassembled.
Additional factors which will lead to bulb replacement costs may include accessibility of replacement bulbs, location of availability of labor force and scheduling of necessary equipment for bulb replacements.
Lamps both prevent and provide hazards as they operate and burn out. When lamps fail to perform they may also fail to provide the light required to safely complete a task. If stairwell, hallway or carport lamps are not functioning the opportunity for Injury or assault may be increased. As a proven deterrent to injury and crime, the proper functioning of electric lights has been encouraged for years. The use of PowerDisc™ greatly reduces the likelihood of insufficient illumination due to lamp failure.
Do you speed up (or slow down) as you drive a long stretch of highway and not notice the change until you check your speedometer? Everyone does. Cars have speedometers because eyes do not measure speed.By the same token, eyes do not measure light outputs they merely sense general degrees of light - dark, dim, and bright. Estimating the relative light output of two light sources with the naked eye will give an erroneous result because the eye is sensitive only to brightness differences (contrast), not the amount of light. This is an extremely subjective matter. In an article by Donald K. Ross from "Lighting Design and Application", April, 1979, it was noted that an actual change in brightness of approximately 26% must occur before it can be perceived. Therefore, in virtually any application, except that of reading, the drop in light output in general will not be serious.
Air conditioning is a higher drain (and cost) on energy consumption than light bulbs. Since 90% of the energy consumed by a light bulb is emitted as infrared or heat energy, this excess heat has to be compensated for in the air conditioning load. Any reduction in operating temperature of a light bulb translates into reduced load on the air conditioning system, which contributes to overall reduced energy consumption.
As it is well known in the industry, all energy efficient light bulbs will have some reduction in lumens (light output), initially up to 30%. This also occurs with the Powerdisc™ - life extender in place. If it is necessary to maintain similar lumen levels it is recommended to increase the wattage of the light bulb used. The lumen level of the light bulb is dependent upon the manufacturer, clear or frosted and type of light bulb being used.
When lamps fail, the choice for replacement is generally made by a maintenance laborer with no appreciation of lamp operating costs. The selection of replacement lamps can, if incorrect, be a costly error in judgment. In almost any commercial enterprise the lack of lamp uniformity becomes obvious upon inspection - even when a company mandate has stated policy on correct type/wattage lamp for use in particular areas. When an outdoor floodlight is incorrectly substituted for an indoor floodlight through improper selection or lack of correct inventory at the time of replacement; the price difference in the lamps acts like a penalty of $2.00 to $5.00 per lamp. When a 100W lamp is incorrectly substituted fora 60Wlamp, the difference in electrical consumption for one socket can be as high as $25.00 (or more!) per year. A survey of a.major retailer's cashier lamps recently demonstrated this problem: Where the light of a 25W lamp was sufficient for the purpose at hand, lamps of 25, 40, 60, 75 and 100 watts were found in 14 different fixtures!
Eliminate the cost associated with discarding hazardous waste (CFL/LED). Reduce harmful side effects of having fluorescent lighting, thereby making for a healthier atmosphere. In a business setting, you minimize liability for broken CFL bulbs, especially in guest rooms –phosphor coated glass, the mercury, UV radiation, EMFs (dirty electricity), etc. In a residential setting, you will keep your family safer and healthier!! Just as important, you will help save our planet!
Costly decorative lamps have become the norm for commercial enterprises used as accent or non-task illumination, these small bulbs require considerable service and expense to maintain. The small amount of light that these lamps produce is rarely related to safety, security or task performance. Why are they so expensive and short-lived? The PowerDisc™ has demonstrated over and over that these non-task lamps can be made to tolerate far beyond their rated lives, without affecting task requirements or the desired ambiance.
Advanced Lighting Technologies 2X Line (as featured in Time Magazine May 2013) – Their 72 watt bulb has the same lumen output as a 100 watt bulb, and with the PowerDisc™ will only use approximately 37 watts. It is a great bulb, and is new technology. The filament is a little more fragile, so if it is used in an area where it won’t get bumped, the results should be very pleasing. Rule of thumb – if you need to maintain the same lumens try going up to the next wattage level. 60W go with 75W, 75W go with 100W, etc. Remember the PowerDisc™ can also be used outdoors for any light or flood light up to 350 Watts, even motion detector fixtures. Weather is also not a factor, unlike CFLs and LEDs. COMING SOON: Look for the new incandescent bulb line from Intelligent Lighting Corp.
Yes there is! 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 PowerDisc™ 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 Formula: General Electric Incandescent Bulb Life Extension Calculation
