LED Lighting
General Info:
MinionsWeb offers a number of different LED lighting options for your home and haunt. This FAQ is to help you understand and capitalize the benefits from using LEDs.
LED bulbs and candle alternatives help set the atmosphere and mood of your display.
Some of the benefits to using the LEDs are:
No Hot Wax or bulbs - LEDs run exceptionally cool, and are inherently safer than flames or incandescent lighting.
No Fire Hazard - You are not burning any wax, and generally using batteries for the power source.
No Wind Effect - Illuminate indoors and out without the fear of the lights going out on windy days, or from drafts inside.
Strong and durable - Withstand shocks, vibrations, frequent switching and temperature extremes that rapidly incapacitate fragile incandescent lamps.
Flame flickers like real candle - Circuits driving LED tealights and candles are far more sophisticated than you suspect, making stunning realistic flame lighting.
No smoke or carcinogens to worry about - LED tea lights we offer look like candles without the wax! Many can be retro fit in hurricane style lamps easily, no soot, no smell, no smoke, no CO2!
Beauty - LEDs produce sharp, vibrant colors… even pure white. Response times are 100 to 1,000 times faster than incandescents so there’s no flicker — just pure dramatic light.
Versatility - The only limit is your imagination.
Long life - Typical LED lifetime 100,000 hours, that equals thousands of candles or light bulbs, at a tremendous savings over years. Compare it to a job, you work roughly 2000 hours per year, if the LED bulb or candle were to be on 40 hours per week, it will last 50 years!
Why use LED lighting?
LED lights are extremely efficient compared to standard incandescent lighting. No other lighting source outputs as many lumens per watt. They are particularly efficient at producing a single color of light. Other light sources have to produce the entire spectrum and optically filter out unwanted colors. However, LEDs can be manufactured to produce only one wavelength of light. This makes them particularly useful in stop lights.
Another advantage to LEDs is their operating temperature. Most available today can be function for hours and remain cool to the touch. Directionality is another key property. They only emit light over a relatively small angle. This can be advantageous for reading lights, but hinders performance when attempting to light an entire room.
Energy saving - The candles and teallights typically run several days on a set of batteries. 50 LED Floods can run off the same power as 1 - 100 watt incandescent flood. The bulbs are 10 to 50 times more energy-efficient, thus reducing your operating costs by up to 90%.
How much energy can be saved with solid-state lighting?
A little over one-third of all primary energy is used for generation of electricity, and a little over one-fifth of all electricity is used for lighting. Hence, around one-fifteenth of all energy is used for lighting in the United States.
Doubling the average luminous efficacy of white lighting through the use of solid-state lighting would potentially:- Decrease by 50% the global amount of electricity used for lighting.
- Decrease by 10% the total global consumption of electricity (projected to be about 1.8 TW-hr/year, or $120B/year, by the year 2025).
- Free over 250 GW of electric generating capacity for other uses, saving about $100B in construction costs.
- Reduce projected 2025 global carbon emissions by about 300 Mtons/year.
That is very green! Every day, LEDs are replacing incandescent lamps all around the world.
Applications:
Safe portable night light
Window displays
Ideal for decor ambiance mood lighting
Restaurant/club candle table light
Ideal for night party candle lights around garden, pools, decks, or patios
LED Candle Unit may be suitable for other candle holders
Inside pumpkins, no melt or burm or rot!
Question: LED intensity comparisons
How do I compare the brightness of different LEDs?
Answer:
Generally LED intensity is measured in mcd (millicandela).
Due to advances in technology some very bright LEDs are now called out in cd (candela).
It is always important to know the intensity in mcd/cd and the full angle of illumination taken at specific drive current (measured in milliamps, mA). To accurately compare one LED to another, the Angle of Illumination and current levels must be the same. One must also be careful to verify the published specifications from any supplier.
Recently the latest technology wide-angle LEDs that put out light flux similar to incandescent bulbs have intensity readings called out in Lumens. These lumen readings, taken at a set drive current (mA), remain the same regardless of beam angle.
