 CR CRYSTAL LED 78 Watt 76mm Post Top Lantern


The CR Crystal is an LED Luminaire that excels

in optical performance, thermal management, 

compatibility and serviceability, resulting in an

uncompromised outcome of  efficiency and 

versatility that is future-proofed for an optimised


The CR Crystal has been designed to meet

most demanding lighting requirements, being

easy to install and maintain. It combines the

latest LED light source with state-of-the-art

esign, achieving longevity for both LEDs and

the drivers. The installation is simple and fast,

and the luminaire is easily upgradable on-site

if required. The CR Crystal is the ultimate solution

to replace traditional HID sources. Being

lightweightand having a low profile wind area

enables the CR Cystal to be safely installed on

existing lighting columns and brackets.

Exceptional Optical Performance

Standard Neutral White LEDs ( CCT = 4000K )

Colour Rendering Index > 70

Improved mesopic vision


High quality PMMA lenses

Exceptional uniformity

Dark sky-friendly ( zero upward light )

Minimal glare ( up to G6 ) 

The CR Crystal uses widely spaced LED chips,

combined with a large surface cooling area as

well as longitudinal fins to avoid any centralised

heating problems which occur in a typical

modular LED luminaire design, thus maintaining

all LEDs at a low temperature. The complete

separation of the driver compartment from the

LEDs keeps the drivers very cool, significantly

increasing the luminaire operating life in high

ambient operating temperatures.
