animals with enough and the right UVB to allow it to produce its own vitamin D3.
While broadband UV meters like the Solartech 6.2 cannot be simply used for comparing lamps they are still
very well suited to judge the aging of a lamp and indicate when the lamp should be replaced. We recommend
replacing the Bright Sun if the UVB output has dropped by more than 50%.
Which Bright Sun fits to my terrarium?
Since the requirements of the animals can be quite different and the terrarium size affects the usability of
a UV lamp as well, we are offering a wide line of different Bright Sun models:
Bright Sun UV Desert
35W, 50W & 70W
Bright Sun FLOOD Desert
70W
Bright Sun ULTRA Desert
150W
Bright Sun UV Jungle
35W, 50W & 70W
Bright Sun FLOOD Jungle
70W & 150W
There are “Desert” and “Jungle” models which are designed for different habitats.
The “Desert” was designed for reptiles from open landscape (e.g. deserts or savannahs) and offers an
unfiltered, whitish light with high UVA performance. It enhances the earth-colours of such habitats. This
model is excellent for bearded dragons and Co.
The “Jungle” has a lower colour temperature with higher yellow, red and green contents as the “Desert”
lamp. The light of this lamp appears warmer and resembles the natural light conditions in forests where
leaves and branches filter and bend the sunlight. The green colours in such habitats are enhanced by the
“Jungle” spectrum. The UV performance is slightly lower in correspondence with the habitat. This model is
excellent for forest species like green iguanas but also chameleons and Co.
The Bright Sun UV models are used for creating local sun spots. The heat performance in the light cone is
comparable to incandescent spot lamps of the same wattage but the total heat output is lower.
The Bright Sun UV ensures high light intensities and the right sun spots thanks to a relatively tight focus.
Contrary to that the Bright Sun FLOOD have a larger reflector which distributes the light over a wider area.
They are designed for a wide scale illumination and are therefore excellent for large terrariums. Due to
the great light diffusion the local light intensity and UV performance is slightly reduced compared to the
Bright Sun UV. However, they are more suitable for large animals which might not fit fully under a Bright
Sun UV for proper sun basking.
A very special product is the Bright Sun ULTRA which essentially is a combination of the previous two mo
-
dels. Thanks to a special front glass construction the light is distributed over a large area as with the FLOOD
lamps but also focuses a lot of light, heat and UV in the middle of the light cone. This makes the lamp perfect
for higher terrariums in which it will show a not yet known performance. It is absolutely necessary to
maintain a minimum distance of 50 cm to the animals
