Atlantis Solar  LED Court Yard Light Model AS-GL052


High pressure sodium left versus LED lighting right. LED lighting is closer to true daylight because temperature can be more precisely controlled. True to daylight translates to the perception of greater safety in parking garages. On roadways it means less visual fatigue. In architectural and accent lighting LED's allow improved lighting rendition. LED's start instantaneously and do not flicker or hum. They produce almost no heat and maintenance is reduced because of fewer replacements, and of course the main advantage: they require less energy.

 

Lighting Efficiency Comparison

Just as an automobile's fuel efficiency is measured in miles per gallon, light bulb efficiency is measured in terms of lumens per watt—the amount of light produced for each watt of electricity consumed. More lumens per watt means more light for your money

 
Fluorescent (tubular)
Life span: 10,000 - 20,000 hours
Pros: bulb burns cooler; very efficient; can come in various CRI ratings; comes in different color temperatures
Cons: not dimmable; fixtures are more costly; known to flicker at times.
Efficiency: 33 - 100 lumens per watt
Uses: General, floodlights
Notes: frequent switching on and off reduces efficiency.

Compact Fluorescent
Life span: Up to 10,000 hours  
Pros: efficient  
Cons: cost of bulb; sometimes they can't physically fit; to replace incandescent bulbs  
Efficiency: 44 - 80 lumens per watt  
Uses: General lighting  
Notes: frequent switching on and off reduces efficiency.

Metal Halide
Life span: 6,000 - 10,000 hours  
Pros: extremely efficient; give a brilliant light; bulbs come in different color temperatures; good color rendering.  
Cons: cost of both fixture and bulb; burns hot  
Efficiency: 60 - 125 lumens per watt  
Uses: places where a lot of light is needed such as outdoor areas and retail shops. Used frequently in sports arenas, stadiums, auditoriums, and convention halls  
Notes: not to be used near flammable materials. Bulbs usually must burn in a certain position.

LED
Life span: 30,000 - 80,000 hours (100,000 hours)  
Pros: High durability - no filament or tube to break; long life span; low power consumption; low heat generation.

Pays for itself immediately.
 
Cons:    
Efficiency: 80 - 200 lumens per watt  
Uses: wide variety of uses including general lighting, accent lighting, decorative lighting, home, parks, shopping centers, streets and highways. (Uses are unlimited)  
Notes: LED technology is relatively new, and is changing every day. The quality and efficiency of the bulbs / chips are improving all the time.

The ratings in parentheses (above) are the predicted improvements which are expected to come about within the next few years.

Mercury Vapor
Life span: 1600 - 6000 hours  
Pros: more efficient than incandescent and halogen; gives a nice color to landscapes.  
Cons: lowest efficiency of the HID type bulbs; dims rapidly; bad color rendering  
Efficiency: 20 - 63 lumens per watt  
Uses: landscape illumination, outdoor lighting  
Notes: produce a blue-green light  
 

(TOP)

 
High Pressure Sodium
Life span: 18,000 - 24,000 hours  
Pros: extremely efficient, long lasting,  
Cons: bad color rendering, produces yellowish light; slowly lose their brightness with  short period of time, operates very hot and uses a lot of energy.  
Efficiency:  60 - 125 lumens per watt  
Uses: very popular for indoor horticulture, outdoor and industrial applications  
 

(TOP)

 
Low Pressure Sodium
Life span: approximately 16,000 hours  
Pros: one of the most efficient bulbs there is, long life span.  
Cons: worst color rendering (monochromatic) of all the bulbs, initial setup can be costly  
Efficiency:  90 - 180 lumens per watt  
Uses: security lighting or indoor applications like stairwells  
Notes: monochromatic -  all colors under this light appear black, white, or shades of gray.
 

The customer should be made aware of lamp efficiencies and operational life in situations where a lamp is to be left on for long periods of time or is not easily accessible for replacement. The energy consumption of a large lighting system is considerable. For example in a commercial building the energy costs of the lighting system may be 30 to 50% of the total energy costs.
