The Bright Sun lamps are the newest innovation in reptile lighting.
They offer heat and UV radiation and most importantly a very high
light intensity.
Finally it is possible to imitate the sun inside the terrarium. In nature
reptiles enjoy a light intensity of over 100.000 lux which is beneficial
for their well being. Normal terrarium lighting will only reach a frac-
tion of this and most terrariums will have a light intensity of less than
10.000 lux which is corresponding to the brightness of shade.
The Bright Sun UV lamps achieve more than 100.000 lux at a distance
of 30 cm which brings them closer to the sun than any other reptile
lighting. The Bright Sun FLOOD lamps have a wider beam angle and
achieve a larger scale and more efficient illumination of the terrarium.
The Bright Sun are metal halide lamps which require a ballast for ope-
ration. Please read carefully the chapter "Information on the
use of metal halide lamps".
Information on UV:
UV radiation (UVA and UVB) in general has a beneficial effect on live or-
ganism but can also be harmful (e.g. sunburn, skin cancer with humans).
The influence of UV on reptiles is not very well researched. It can be
assumed though that reptiles can see inside the UVA spectrum and that
this part of spectrum plays an important role in their life (e.g. choosing
a breeding mate). UVB allow reptiles (and also humans) to synthesize
Vitamin D3 from elements available inside the body. Vitamin D3 is im-
portant for the utilisation of calcium and ensures a healthy bone and
carapace growth. UV radiation can therefore help to prevent metabolic
bone diseases. It can also be assumed that there is a positive effect on
the general wellbeing of the animals.
Accurate research and scientific data for reptiles is hardly available
though. It is not know what the UV dosage should be in order that
the animals benefit properly as well as at which dosages UV might be
harmful.
Since humans will synthesize the maximum amount of Vitamin D3 that
is biologically possible within 10 minutes of being exposed to natural
sunlight, it can be assumed that reptiles will also not need a UV exposu-
re of several hours at high dosages.

Manual
Due to the potential dangers of UV radiation we consider it safer not to
expose animals to extremely high UV outputs. Over the years reptile
UV tubes have produced good results and also the long experience with
other UV bulbs suggest that reptiles do not need the same UV intensity
like in nature when being kept inside a terrarium.
The Bright Sun UV lamps have been constructed to supply about half
of the Central European sun's UVB dosage at distances of 30 cm. The
maximum distance to the animals should not exceed 50-60 cm for the
Bright Sun UV Jungle (both wattages) and Bright Sun UV Desert 50W
and 70 cm for the Bright Sun UV Desert 70W. The minimum distance to
the animals should be at least 20 cm for the 50W models and 30 cm for
the 70W models. The Bright Sun SPOT and the Bright Sun ULTRA were
developed for larger vivariums and achieve at 50 cm distance about the
performance of the Central European sun. For safety reasons we cannot
recommend to expose animals at lower distances to this lamp. The UV
radiation is effective up to a distance of 120 cm. The Bright Sun ULTRA
has a wider reflector which allows for a large scale illumination while
the Bright Sun SPOT has a tight focus.
The Bright Sun FLOOD were developed for large scale illumination of
the terrarium but also provide UV. For species with lower UV require-
ments they can be used as sole light source. The minimum distance to
the animal should not be lower than 20 cm.
Please note that the UV performance will decrease to about 50% of ist
original within 2000 hours of use.
