Emergency Lighting
YES - Our 2D Retrofit range includes our 2DRE and 2DRME series which combine an energy efficient lamp with integrated emergency functionality. Emergency options for our LED flat panels is also now available.
Our emergency portfolio is growing to include self contained emergency luminaires. Click here.
A. The backup light source in our 2DRE LED lamp, whilst integrated into the lamp, is actually independant electrically. As a result, the 2DRE main lamp can be connected to a switched supply. The emergency backup pack included with the 2DRE is designed to operate in non-maintained mode, so MUST have a permanent supply. On a power fail, the whole luminaire with lose its power, and the emergency gear will illuminate the High Power LED backup lamps inside the 2DRE for a minimum of 3Hrs. All of our Emergency gear is ICEL approved.
Installation
YES. In a standard switchstart fitting, removing the existing starter and replacing it with the VI starter (supplied with the LED tube) is all that is required.
YES. All you need to do is isolate the HF gear from the circuit so that mains power is supplied direct to the LED tube.
YES. All you need to do is bypass the HF gear and connect the mains direclty to the 2DR lamp.
LED Technology
An LED or Light Emitting Diode is a semiconductor based light source. They come in various colours including white.
A White LED is usually made up of a blue LED with a yellow phosphor on top. The more phosphor is applied the more yellow(warm) the light will be.
LEDs have the advantage of not emitting Infrared or Ultraviolet light ao their heat generation is much lower than an incandescent or fluorescent lamp and hence their efficacy (Watts to lumens generating efficiency) is higher.
A common misconception is that LEDs do not generate heat. An LED efficiency is only around 15%. Therefore, 85% of the power used by an LED generates heat.

NO. Absolutely not, unlike fluorescent based lamps which have to rely on high energy 'strikes' to start the lamp and thus reduce its lifetime. LED lamps are solid state electronic devices and do not suffer with consistant on/off cycles.
Lighting Efficiency
A. LED flood lamps produce a higher colour rendering and appear 'brighter' compared to tradional flood lamps. As a guide, our 20W Flood would be equivalent to a 300W Halogen or 70W SON, and the 50W Flood equivalent to a 500W Halogen. Our 120W dual emitter LED flood lamp would produce the same amount of light as a 400W Halide based lamp.
As an specialist in LED lighting, we are suprised at the misinterpretation of the the word EFFICACY. Be aware that many companies less experienced will simply quote efficacy as the lm/W figure based on the power which is consumed by the LED lamp. This gives false information and not a true representation of the 'actual' power being taken from the system. When we say 'system', we mean the inclusion of the actual AC/DC converter that takes the AC mains and turns it into a low voltage supply required to drive the LED circuit. There is no such thing as 100% efficient power supply, and most LED drivers have efficiencies ranging from around 75 - 85%.
When we quote our efficacy figures, we always take into account the 'system' power.
The higher the efficacy (lm/W) the better the lamp / luminaire in terms of the amount of lumens (lm) per Watt (W) of circuit power.
Stay clear of any products with an efficacy of less than 50lm/W (due to Part L Buiding Regulations)
2DRM Motionsense Specific
A. Yes we do. It is called the 2DRME series. Same emergency options as our standard 2DRE series.
A. The 2DRM turns fully off ad fully on when movement is detected. In the 2DRMD version, the lamp reduces to 10% brightness when off and 100% when activated.
A. Our in-house designed high frequency sensor is very low power, so on the 2DRM version, standby power of <1W can be realised. When the 2DRMD version (10% DIM) mode version is used, the power is just 2W.
A. Our product uses high frequency microwave energy, similar to that used on advanced security systems. As a result, the sensor relys on bouncing radio waves rather than detecting infra-red body heat changes like a PIR.
A. Turn the timing (T) control pot fully anti-clockwise to minimum.
In this mode, the timing is set to just 3 seconds, and adjusting the sensitivity (S) pot clockwise, will allow range tests to be performed. Once set, the timing control can be adjusted clockwise to the required ‘time-out’ period from 6 seconds to 45 minutes.
General FAQ's
A. No. We dont sell direct to the public, and as a UK OEM manufacturer/supplier, our route to market is through wholesalers and energy partners. We are more than just a lamp supplier, and go that extra mile to work with our clients to understand their objectives and provide costings on a project by project basis.
