1. Lamp technology - luminescent material - LOW-PRESSURE TUBES
Ultraviolet luminescent lamps consist like normal fluorescent lamps, which are used for general lighting, of a glass bulb which is changed on the inside with a phosphorous luminescent layer and is melted together on both ends and is air-tight.
~On both ends of the lamp there are electrodes (1).
~The glass bulb is filled with mercury vapor which is under a low pressure (low-pressure discharge lamp).
~If voltage is applied to a lamp, after starting electricity flows through the electrodes and the electrons (electrically loaded particles) are sent from one electrode to the other (2). On the way, the collide with mercury atoms (3) and are activated to radiate (4), whereas in the lamp at the first short wave ultraviolet C radiation results.
~When impinging on the luminescent coating (5), the ultraviolet C radiation is changed into ultraviolet radiation with longer waves (6) with a defined spectrum.
~The spectrum produced by the lamp is above all determined by the characteristics of the used illumination material as well as the spectral permeability of the bulb glass determined and changed through the optical components of the solarium mostly only unessentially in its composition.
~If for example ultraviolet A radiation is desired, a luminescent phosphorus is used which radiates a spectrum with a maximum of approx. 340 to 360 nm.
~Through variation of the luminescent material and through the use of glass bulbs with differing ultraviolet transmission, above all the size of the given ultraviolet B share and the radiation capacity of the lamp can be influenced.
2. Reflector - TECHNOLOGY
With reflector lamps in the glass bulbs a reflector layer is added (integrated reflector).

~With these lamps, outside reflectors are no longer needed since the radiation already directedly leaves the glass bulb.
~In most common solariums today, reflector lamps can be used since the devices are correspondingly constructed.
~In particular with home devices in which often there is also an external reflector built in, but also in some professional solariums with which the distance of the built in lamps is very far, it is recommended to insert a lamp which radiates from all sides. Find out more information about the discribed devices at your NEW TECHNOLOGY dealer.
~Reflector lamps reach approx. 25 % higher ultraviolet radiation strength than lamps without reflector.
~Depending on the model of a lamp, the reflector angle can be between 180° and 230°.
3. Quality characteristics of LOW-PRESSURE TUBES
Ultraviolet A capacity
High ultraviolet A capacity of a lamp secures the desired immediate tanning (direct pigmentation).

Ultraviolet B capacity
Ultraviolet B radiation causes, through stimulation of the cells which form pigments, the indirect pigmentation of a long-lasting tan.

Transmission of the bulb glass:
The distinction is made between the "closed glass" and the "open glass". With the use of the "open glass" for the production of the bulb glass, the permeability (transmission) increases of the radiation spectrum pruduced in the lamp. Low-pressure tubes with an "open glass" generally have a higher ultraviolet capacity.
Electrode technology
The electrode technology differentiates standard lamps and high-performance lamps. Standard lamps have a shorter electrode framework, high-performace lamps have generally a longer electrode framework. The long electrode framework has an influence on the cooling of the lamp and correspondingly on the performance and the use life span. In addition to the electrode technology, there are numerous further components which add to the quality of ultraviolet lamps.

Useful lifetime
Standard lamps and high-performance lamps differentiate themselves in their useful lifetime. Standard lamps have a useful lifetime of approx. 400 - 600 hours. High-performance lamps have a useful lifetime of approx. 800 - 1000 hours.
4. UV-A and UV-B performance of LOW-PRESSURE TUBES

Important parrameters for the use of the optimal ultraviolet tubes in the professional solarium are in addition to the useful lifetime the ultraviolet A and the ultraviolet B performance of a low-pressure tube.

The ultraviolet A performance ability of the NEW TECHNOLOGY low-pressure tubes is given in the ultraviolet A radiation strenght in mW/cm² (E UVA in mW/cm²).
The energetic radiation strength of the ultraviolet a characterizes mainly the direct or immediate pigmentation of a low-pressure tube which is decisive for a quick tanning result through ultraviolet A radiation.
The ultraviolet B performance ability of the NEW TECHNOLOGY low pressure tubes is represented through the sun-erythema-factor (SEF). The sun-erythema-factor (SEF) gives the relationship of of the given erythema effective radiation strength of the ultraviolet tubes to the approximate maximum of the erythema effectiveness of the equatorsun at noon at sea level with a clear sky (reference sun). A sun-erythema factor of lower than 1 means a low erythema effectiveness of a higher erythema effectiveness of the ultraviolet tubes in comparison to the reference sun. A sun-erythema-factor of SEF 2 for a low pressure lamp thus means twice the erythema effectiveness radiation strength as the reference sun on the equator.
