Warranty

Is measured in life hours, so if it is 50,000 hours @ 12 hours useage per 24 hour period, then the warranty is 11.5 years.

Check each page for full warranty details

Lifespan

The lifespan is measured by quoting the industry standard L70.This is the measurement in hours before the unit reaches 70% of the brightness from its original - this is called 'lumen depreciation', and for all our lights is > 100,000 hours.

This compares to a life expectancy of 22,000 hours for HPS, and 17,000 hours for LPS.

To help you make informed chooses, here is more detail as to what some of the technical terms mean:

LED Power:  Wattage needed to power the LED chips

 

Total Power:  Total wattage needed to power the complete light unit - sometimes called circuit wattage

 

Power Efficiency:  Is a percentage measurement on how efficient the unit is in converting energy into light.

Luminous Flux:  This is the measurement in lumens of the perceived power/brightness of the light by the human eye

 

Real Luminaire Efficiency: Is a measurement obtained by dividing the Luminous Flux by the LED Power

 

Lux and Lumens:  A single lux is equal to one lumen per m2

 

Colour Rendering Index [CRI]: The CRI of a light source is the ability on a scale of 1 - 100 to reproduce the true colours and sharpness of objects in comparison with natural light  

Operational Temperature Range:  The range of ambient temperatures that it is safe for the unit to operate within, that will not harm its design life

 

Junction Temperature: Is the highest operational temperature of the semi-conductor in the LED unit.

It is critical for the life of the unit that the temperature is kept as low as possible.

This is achieved by quality designed chips, driver and heat sink.

Lower junction temperatures generally result in a longer life.

 

Power Factor:  This is a the ratio of the real power that is used to work and the apparent power that is supplied to the circuit. It is measured in a range of 0.1 - 1.0

Colour Temperature [CCT]:

The colour temperature of the LED light you choose, is important for quality of life for humans, animals and our environment.

The ranges are: Cool White: 5000k - 7000k, Neutral White: 3700k - 5000k, Warm White: 2600k - 3700k.

We recommend:

Housing Area street lights between 2700k - 3200k [3000k is max to comply with Dark Sky legislation

Commercial Areas, Road Junctions and Security areas, 3700k - 4200k, this will supply a clean crisp light that will make it clearer in defining cyclists, people and colours. This range is good with CCTV capture.
