The equivalent incandescent lamp value can be found in the table 6 of EU-Regulation 244/2009 (VO 244).

The following must be noted:

1.) Reg. 244 has made a simplification and taken only the luminous flux of standard (clear) incandescent lamps as a basis; it has not taken into account that the actual luminous flux of the lamps being replaced may be lower due to the white-coated glass finish.

Example:
Luminous flux of a 40 W incandescent lamp, frosted: 415 lm (lumen);
Luminous flux of a 40 W incandescent lamp, white coated interior (like a LEDON LED lamp): 370 lm;
Luminous flux of a  6W LEDON LED lamp: 400 lm;
The LEDON LED lamp has more light output than the similarly white-coated incandescent lamp, however the EU regulation 244 specifies the comparable equivalent is only 35 W.


2.) The characteristics of the light distribution of LED lamps are different from that of incandescent lamps. Incandescent lamps radiate light in all directions; LED lamps emit light more in one direction. This often has an advantageous effect on the brightness of the illuminated area and depends on the type of application. This was also not taken into account for the sake of simplicity in the Reg. 244.

 

Example:
A 60 W lamp in a pendent light fixture radiates light in all directions and some of the light is reflected indirectly downward by the reflector onto the surface of a table. A 10W LEDON LED lamp distributes the light predominantly hemispherically downward and lights the surface of the table directly, making it a more efficient.
The light emitted by the LEDON 10 W LED lamp in the application example is perceived as brighter than that of the 60 W incandescent lamp.

Similar effects can also be seen with floor lamps. Practical tests have confirmed this.*

Specially performed laboratory measurements have confirmed the practical trials. When comparing the light distribution pattern of a LEDON 10 W LED lamp and a 60 W incandescent lamp (see picture), it becomes obvious that directly below the luminaire (at 0°), the brightness of the LEDON 10 W lamp (about 99 candelas) is  approx. 57 percent higher than that of a 60 W incandescent lamp (about 63 candelas).

Unit of measurement: Candela [cd]

*Exception: In fixtures with glass shades, where the all-around light radiation is used for the effect of the luminaire itself, incandescent-like radiation is an advantage. 

Because under the EU Regulation 244/2009 the required light output (luminous flux) emitted by an LED lamp is required to be about 14% above of the light emitted by an equivalent incandescent lamp.

1. Non dimmable and Double-Click lamps must not be used with dimmers.
Operating a non dimmable or Double-Click lamp with a dimmer can destroy the lamp or the dimmer and presents a danger of overheating (Even if the dimmer always stays on maximum). Some of these lamps may appear to function on a dimmer switch; however this also presents a danger of destroying lamp/dimmer and is a safety hazard and should not be attempted.

2. Installation: VA rating.
When several lamps are operated in a single installation or on a single dimmer, the VA rating of the installation or dimmer switch must be multiplied by at least factor five to six. As a general guideline the VA rating must be sized for incandescent lamps which the LED lamps replace. This is also applicable for both dimmer and fuse sizing. For example: if five 10W lamps (5 x 10W) are operated, the VA rating must be at least 250-300VA.

If you have any doubts or questions regarding installation please consult a qualified electrician.

3. Do not operate lamps with broken glass dome or without the dome.
Because of the risk of electrical shock lamps without domes or with broken domes should not be used anymore and should be disposed of immediately even if they still are operational.

Since 1 September 2010, the European Union has regulated the labelling of packaging for LED lamps. As a picture is worth a thousand words, the following icons can be found on the LEDON packaging:

	Number of switching cycles
	Double-Click By double-clicking your light switch, the LED lamp is dimmed down to 30 per cent of its original brightness.

Demand switches need a certain minimum load to work properly. As LEDON LED lamps are very efficient, it can happen that the necessary minimum load of your demand switch is not reached. In order to solve this problem, please contact the manufacturer of your demand switch.

 

It is possible to use LEDON LED lamps in all sorts of luminaires that are suitable for the use of equivalent incandescent lamps. Therefore, every luminaire – open or closed – is suitable for the use of LEDON LED lamps. However, it is recommended to only use LED lamps that correspond with the wattage of the replaced incandescent lamps. For example if you want to replace a 60W incandescent lamp which was used in a closed luminaire you should use a 10W LEDON LED lamp.

Unfortunately, some dimmers are not suitable for use with highly-efficient LED lamps. In order to facilitate your decision to buy a dimmable LED lamp or a suitable dimmer, we test our lamps with common dimmers available on the market.

Using a dimmable LED lamp in combination with an unsuitable dimmer may lead to a mechanical hum in the dimmer as well as in the lamp. Furthermore, it is possible that the LED lamp starts to flicker.

Non-dimmable LED lamps and LED lamps with a double-click option are not suitable for use with dimmers. Using non-dimmable and double-click drivers with dimmers could cause a mechanical hum. With some dimmers, this sound can occur even if the light switch is set at the maximum of light output. The reason for this, is that some dimmers regulate the light output even when set at the maximum. Therefore, only dimmable LEDON LED lamps should be used with dimmers.

LEDON LED lamps rated at 10W are mostly compatible with commonly available motion detectors. Lamps with a lower energy consumption, however, can be incompatible with some electronic motion detectors.

As opposed to incandescent lamps the beam angle of LED lamps is significantly smaller. In an ideal situation they are used with luminaires setting the distribution direction. Taking the beam angle of the luminaire into account means that LEDON LED lamps achieve an even greater light output compared to conventional light sources.

LEDON LED lamps should only be used outdoors with a suitable luminaire. The respective protection class is determined by the luminaire.

LEDON LED lamps can be switched on and off without wear (up to a million switching cycles).

The limiting factor for the service life of LED lamps is the ambient temperature during its operation time. The indication on LEDON LED lamps concerning the service life applies for ambient temperatures ranging from -25°C to +45°C and an average use of 2.7 hours per day when stated in years.

The most important factor determining the service life of LEDON LED lamps is the ambient temperature. Considering the fact that it is theoretically possible to use the lamps for 17,520 hours in two years (365 days x 24 hours x 2 years), the warranty period of two years is realistic. By comparison incandescent lamps have an average service life of only 1,000 hours.

At the end of the indicated service life period, the luminous flux of LED lamps should be at least 70% of the original light output. All LEDON LED lamps meet this requirement.

In Central Europe, warm-white light with a colour temperature between 2,500 and 3,000 Kelvin is considered comfortable. LED lamps produced by LEDON mainly cover this range of colour temperature and the light can be compared to the one we are used to having with incandescent lamps.

When comparing various suppliers of LED lamps, the most significant difference in quality can be seen in terms of luminosity and light quality. Luminosity is indicated in lumen (luminous flux) and constitutes an important means of measure. Leading consumer magazines, for example classify 60W and 40W incandescent lamps with 600 and 400 lumens respectively. LEDON Lamp offers corresponding replacements in this field by producing and selling its 10W LED lamp (600 lumens) and its 6W LED lamp (400 lumens). 
In terms of light quality it is the colour temperature and colour rendering that counts. LED lamps produced by LEDON cover the whole spectrum of visible light – they have a similar colour temperature and colour rendering to incandescent lamps.

Only use low-voltage LED spotlights with appropriate transformers providing specified load ranges. In case of use below the base load, increased voltage output may occur, which could damage the LED spotlight. They can be used with virtually all magnetic transformers, however, please note that in case of electronic transformers LED spotlights are not compatible with all commercially available devices.

'The lamp is screwed into the light'. Generally, luminaires are known as lights. But actually the correct word is 'luminaire', and a desk lamp for example is properly known as a desk luminaire. This means that a lamp is fastened into the luminaire and the lamp emits the light within the luminaire.

LED lamps are much more complex to manufacture because they consist of various components: an integrated ballast, the light module and a comparatively complex heat sink.

The 'heart' of each LEDON LED lamp consists fundamentally of a lighting module (amalgamation of several LED chips) and an integrated ballast. As well as the socket for fixing into the luminaires and the glass dome, each LED retrofit lamp also requires a heat sink. This metal housing ensures that the lamp does not become overheated and in addition gives the LED lamps from LEDON their typically elegant design.

Most of the LED modules and integrated ballasts are produced in our own facilities in Europe (Austria and Great Britain). Final assembly is carried out in external, certified manufacturing locations in China.

The engineers working for LEDON Lamp are constantly developing new and more efficient LED lamps. The launch of more powerful LEDON LED lamps is scheduled for 2012.

The most demanding technical challenge concerns cooling of the LEDs. Limitations therefore exist due to the pre-defined maximum dimensions of a lamp. But because of the rapidly advancing technological development, 100 W LED lamps can already be seen on the horizon.
