Aura Crystal TC Long LifeA compact Long Life metal halide for excellent shop lighting

AURA CRYSTAL TC LONG L IFE

Aura Light has developed the first real Long Life metal halide

lamp. It is an efficient and sustainable light source for profes-

sional applications. The twin arc technology creates the long-

est lifetime on the market. It more than doubles the lifetime of

standard products and has a lifetime of 43,000 hours (avera-

ge), 30,000 hours (10% mortality), or seven years.

The lamp is suited for many different environments – from

shop lighting and indoor areas to street lighting and other

outdoor decorative segments. Aura Crystal TC Long Life has

an outstanding lumen maintenance; 80% at 17,000 hours and

reduces your maintenance costs by up to 50%.

• Longest lifetime on the market.

• Reduced cost of ownership.

• Outstanding lumen maintenance

• Faster re-strike after net power breakage.

• High colour stability over lifetime.

• UV protect to prevent fading of fabrics etc.

Ideal for:

• Shop lighting

• Offices

• Street lighting

• Pedestrian areas

• City centers

• Public buildings

Lifetime

The lifetime of Aura Crystal TC Long Life is 30,000 hours

(12B10 = 90% survival rate - 12 h switching cycle). In

professional applications it means seven to eight years of use.

The average life on this 12 h cycle is 43,000 hours.

In installations where lamp replacement is difficult and

costly, the long burning time of Aura Long Life lamps enables

more cost effective lighting and extends maintenance

intervals. Group replacement of lamps provides an optimal

control of operational costs and a uniform level of light in

installations. For economical and environmental reasons Aura

Light recommends group replacement of Long Life lamps.

Long Life guarantee

Aura Light guarantees 30,000 hours lifetime for Aura Crystal

TC Long Life lamps used in installations complying with the

relevant standards. Aura Crystal TC Long Life is developed

and manufactured in accordance with the standard IEC 61167.

Continuous strict quality control processes secure high

intensity discharge lamps of top quality.

Technical Information

Aura Crystal TC Long Life metal halide lamps are designed to

operate perfectly in existing installations. They are designed

for electronic operation, which gives a highly efficient lighting

solution. Dimming is possible according to the defined lighting

levels of the electronic ballast. The lamps work equally well

also with magnetic ballast and separate igniter. The lamps can

be placed in all burning positions. They are in compliance with

IEC 61167 and data are comparable with standard products.

Overview

Aura Crystal TC Long Life is a high pressure ceramic metal

halide discharge lamp developed by Aura Light. It is an efficient

and sustainable light source for professional applications. It

uses two ceramic arc tubes to reach an outstanding lifetime

extension.

Long Life technology

Based on the Aura Long Life technology for high pressure

discharge lamps two ceramic arc tubes are mounted in an

outer glass bulb made of hard glass which results in more

than twice the lifetime compared to standard products on the

market. The arc tubes are nearly circular and placed parallel at

an angle close to the light center in the middle of the bulb. The

robust holding system resists vibration which is important for

the long lifetime.

Lamps with two arc tubes always alternate which arc tube

is ignited, when switching on the lamp. Which arc tube ignites

is determined by the one that needs the lower ignition voltage.

This constant alternating function safeguards the proper

process for the lifetime and lumen depreciation.

Metal halide lamps have a very high temperature inside,

which means that they need a cool down time of five to 15

minutes before re-igniting in case of a net power breakage.

A lamp with two arc tubes has the advantage that the resting

arc tube is less warm and can ignite faster and light will be

available in shorter time. Therefore after a short net power

breakage the inactive arc tube will ignite in up to two minutes.

This means that the light will return much faster with Aura

Crystal TC Long Life, than with comparable single arc tube

lamps.

»The lamp is suited for many different environments – from shop lighting and indoor areas to street lighting and other outdoor decorative segments.«

Aura Crystal TC Long Life offers superior colour quality and

is available in the colour 3000 K with colour rendering over 80

and colour 4200K with colour rendering over 90.

The tubular bulb is made of hard glass, which protects the

components inside and secures the functionality over the long

lifetime. The hard glass is lead free and absorbs UV radiation.

This lamp type must be operated in fully enclosed luminaires.

The luminaire must be able to contain hot fragments of

ceramic and glass in the unlikely event of lamp rupture.

The shape of the ceramic arc tubes allows the lamp to

operate with higher temperature which gives positive effects

on luminous efficacy and colour rendering. Ceramic arc tubes

also reduce the potential risk of corrosion.

High pressure discharge lamps require a run up time to

produce the full light capacity as the temperature and pressure

inside the arc tube need time to reach the full operating level.

This run up time is about four to five minutes.

All Aura Long Life lamps comply with the requirements of

the relevant EU directives, e. g. Eco-Design ErP and the RoHS.

They have to be collected and disposed at end-of-life according

to the WEEE directive.

Applications

Metal Halide lamps with single plug-in cap are used in dif-

ferent applications and in luminaires with deviating sizes. The

two main application areas are:

• Shop lighting, where often downlights are used. They usually

have a specific designed reflector and the lamps are often

positioned horizontally.

• Street lighting, where luminaires like lanterns are used and

where the lamps are installed in different positions.

If you are uncertain about the installation it is recommen-

ted to first check the suitability or contact your Aura Light-

representative.
