- Lamp efficacy
Lamp efficacy
Efficacy is important because the amount of light emitted from a lamp (in lumens) compared to the amount of power used by the lamp to produce it (in Watts) is key for energy efficiency. Both Base LED and Cruz have a high lamp efficacy.
- Ballast classification
Ballast classification
Controlling the electricity supply to the lamp (Energy Efficiency Index).
- Luminaire distribution
Luminaire distribution
Controlling light emission using optics which bend and shape the light to the correct location.
- System efficacy
System efficacy
The use of a high efficacy light source combined with precision optics results in a high system efficacy, producing maximum light output for minimum energy input.
- Presence/absence detection
Presence/absence detection
Presence: Lights automatically turn on/off with movement. Absence: Lights automatically turn off and must be manually switched on.
- Daylight detection
Daylight detection
Artificial lighting which responds to the natural light conditions.
- Constant illuminance
Constant illuminance
A function designed to produce correct light levels for the duration of the maintenance period.
- Task-scene setting
Task-scene setting
The use of dimmable luminaires in conjunction with scene setting controls allows the correct lighting levels to be set for the task in hand, resulting in reduced light levels and therefore energy consumption for a significant proportion of the time.
- Timed off
Timed off
Automatic cut-off can be installed to turn all lights off during unoccupied hours.
- Task lighting
Task lighting
Lighting task areas with the correct amount of light.
- Zoning of lighting
Zoning of lighting
Lighting is zoned according to area use.
- Maintenance schedule
Maintenance schedule
Maintenance must be performed in response to product age, performance and environment.
- Waste light
Waste light
Eliminating waste light which does not hit the intended target.

Thorn luminaires set the scene and save energy at new Elite Hotel Ideon, Sweden
The new Elite Hotel Ideon opened in the Ideon Gateway, Lund's tallest building, in 2013. A modern full-service hotel, it offers 178 rooms, a contemporary gym with sauna and modern conference facilities furnished with the latest technology.
With Thorn Lighting already enjoying a long-standing relationship with the installer, Goodtech Projects & Services AB, Ikano Retail Centre Management approached Thorn to provide a lighting solution in areas including the nine conference suites, gym and kitchen and banking area.
Cruz provides adaptable, comfortable conference lighting
The hotel has a total of nine conference rooms ranging from 17m² to 247m² with layout possibilities including cinema, school, U, board and banquet. The various functions for which the rooms are used demand adjustable lighting.
Cruz 280H 2X42W TC-TELI HFI was chosen due to its high light output (77% LOR), rapid installation (average mounting time takes only seconds) and versatility. Optimised high grade aluminium reflectors produce controlled light for efficient glare-free illumination while radial light distribution contributes to good modelling with a 65% cut-off. Uniform cylindrical lighting is especially important for communication in large conference rooms.
LED luminaires chosen for energy efficiency
Both the hotel and the entire building take sustainability seriously and have a number of energy saving innovations to allow them to be awarded with various environmental certificates. Thorn's luminaires, including Base LED downlights and the recessed modular Omega LED, were chosen because they provide high quality light while achieving energy savings of 50-75% compared to traditional alternatives. Aside from energy efficiency, the fact that Base LED offers a warm colour temperature (2700K) similar to a traditional lamp was a major benefit.
Magnus Ekvall from Goodtech Projects & Services AB says: "We have a good working relationship with Thorn and it usually always proceeds in a smooth manner for all involved parties."
Key facts
- Dimming controls provide maximum comfort and energy savings
- Base LED selected for its warm 2700K colour temperature, similar to a traditional light bowl
