Aura Thermo Long Life

Lighting in low temperature application areas

AURA THERMO LONG LIFE

Aura Thermo Long Life is a tri-phosphor lamp with a very good 

colour rendering designed especially for environments where 

the temperature is low. 

The unique construction contains a Long Life fluores-

cent lamp cased in an outer glass tube, there are four types 

available; Aura Ultimate Thermo Long Life (T8) with an outer 

glass tube of Ø 38 mm or Ø 32 mm, Aura Universal Thermo 

Long Life (T8) with an outer glass tube of Ø 38 mm and Aura 

Supreme Long Life with an outer glass tube of Ø 26 mm. 

This group of lamps are designed for applications such as 

sign lighting, tunnel lighting, car parks, refrigerated counters, 

cooling cabinets and frozen storages. 

•  


Extremely high light output at low temperatures.

•  


Very good colour rendering.

•  


Reduces maintenance with two thirds.

•  


Excellent starting characteristics at low temperatures.

Ideal for:

•  

Sign lighting



• 

Tunnel lighting

•

Technical Information

Both Aura Ultimate Thermo Long Life (T8) and Aura Universal 

Thermo Long Life (T8) have a basic fluorescent diameter 26 

mm lamp inside the outer glass tube with connection pins 

as G13. Operation of these lamps is possible with electronic 

ballast (preferably warm start) and with magnetic ballast and 

starter.

The Aura Ultimate Thermo Long Life (T8) and the Aura 

Universal Thermo Long Life (T8) have an outer diameter 38 

mm and  are very well utilised in luminaires developed for low 

temperature areas which also result in the best light efficacy 

at low temperatures compared to an ordinary diameter 26 mm 

lamp, up to five times as high. 

The Aura Ultimate Thermo Long Life (T8) with an outer dia-

meter 32 mm is predominantly offered in case the diameter 38 

mm does not fit. At low temperatures  Aura Thermo Long Life 

lamp produces up to three times more light than an ordinary 

diameter 26 mm lamp.

The Aura Supreme Thermo Long Life has a fluorescent 

diameter 16 mm lamp with a special design inside the outer 

glass tube with connection pins as G5. Operation of the lamp 

is possible with electronic ballast (preferably warm start).

The Aura Supreme Thermo Long Life has an outer diameter of 

26 mm and is well utilised in luminaires for low temperature 

and outdoor areas if dimensions are not too minimised. The 

special design of the integrated T5 Long Life lamp makes it 

possible to almost reach the same high level of light as the 

Thermo lamp with diameter 38 mm. 

The Aura Thermo Long Life is a high colour rendering tri-

phosphor lamp (Ra 85) and is available in several colours.

Overview

The outer glass tube of Aura Thermo Long Life provides a 

thermal insulation which results in excellent high light output 

at low temperatures. At -20°C Aura Thermo Long Life lamps 

produce up to five times more light than standard lamps under 

the same ambient temperature conditions.  

Group replacement of fluorescent lamps provides an 

optimal control of operational costs and gives a uniform level 

of light. For economical and environmental reasons Aura Light 

recommends  a group replacement of Long Life fluorescent 

lamps.

Lifetime


A lamp’s service life is defined as the elapsed time when the 

amount of light in an installation reaches 80% of its initial 

100 hour value. According to IEC/EN 60081, the service life of 

the lamp failure rate and the lumen depreciation is calculated 

based on the lamp being operated with a switching cycle of th-

ree hours. The three hour switching cycle is defined as having 

the lamp switched on for two hours and 45 minutes and then 

switched off for 15 minutes. 

A switching cycle that is more close to common use is the 

12 hour switching cycle, this is defined as having the lamp swit-

ched on for 11 hours and then switched off for one hour. The 

lifetime shown is accounted for 10% mortality rate. 

Long Life Technology

Aura Thermo Long Life is developed based on our patented 

cathode shield construction. This design provides a unique flu-

orescent lamp with an exceptional long service life combined 

with an improved end-of-life protection against overheating. 

The lumen depreciation process is minimized with a protection 

layer inside the glass tube. 

Long Life Guarantee

Aura Light guarantees 48,000 (Aura Ultimate Long Life), 

36,000 (Aura Universal Long Life) hours service life (Magnetic 

ballast + Starter) and 70,000 hours (Aura Ultimate Long Life) 

50, 000 hours (Aura Universal Long Life) and 48,000 hours 

(Aura Supreme Long Life) (Electronic ballast, warm start) for 

Aura Thermo Long Life for installations that comply with the 

relevant standards. 

Aura Thermo Long Life is developed and manufactured in 

accordance with the IEC/EN 60081-standard. Continuous strict 

quality control processes ensure that fluorescent lamps are of 

top quality.
