Another important feature of the SolRx 500 Series UVB Narrowband device is its
superior Power Density.
Most competitive devices use eight or ten 20 watt 2-foot long single tube "T12" bulbs,
(Philips TL20W/01)
for a total of 160 to 200 watts input power.
These bulbs have a
published
5-hour UVB radiation of 2.3 watts each.
The SolRx 500 Series, on the other hand,
uses up to five 36 watt "long compact fluorescent" twin-tube bulbs,
(Philips PL-L36W/01)
for a total of 180 watts of input power.
Benefited by their superior shape,
these smaller yet more powerful bulbs have a
published
5-hour UVB radiation of 6.2 watts each;
2.7 times that of the TL20 bulbs, with only 1.8 times the input power.
What does this mean to you?
More UVB light power (Irradiance) means
shorter treatment times,
while providing totally adequate coverage
for hand/foot & spot targeting.
It also means an overall smaller device, less weight and far better portability.
Other benefits include lower re-bulbing costs,
because there are fewer bulbs.
PL-L36W bulbs are also considerably more robust than the TL20's,
reducing the chance of breakage.

Narrowband UVB is now the treatment of choice for psoriasis and vitiligo.
More than 90% of SolRx devices use this waveband.

After removal of three fasteners on one side of the guard,
the guard swings open to access the bulbs.
|
The anodized aluminum reflectors behind the bulbs reflect about 90% of the ultraviolet light
and are mirror-like in appearance.
They greatly improve the device's total UV light output. (Irradiance)

The
SolRx 500 Series
is designed for maximum long term utility in a compact, cost effective package.
The various models all use the same main frame,
and differ only in the number of ultraviolet bulbs.
Within the model number, the second digit indicates the number of bulbs.
For example, a 530 has 3 bulbs.
All devices are UVB-Narrowband; however,
the device will also accept UVA (PUVA) bulbs (PL-L36W/09).
While these UVA bulbs are interchangeable,
Solarc does not actively sell any 500 Series UVA devices.
No Users Manuals are available.
PUVA users will have to consult with their physicians for treatment protocols.
A device with more bulbs provides shorter treatment times.
It follows that the best device value can be determined by simply comparing their cost-per-watt.
For example, for a 550UVB-NB, divide its cost by its 180 watts of power,
and compare it to that of other competitive units.
The 500 Series generally always has the lowest cost-per-watt and the highest value,
not to mention its far greater versatility.
The pictures below describe the various models.

520UVB-NB
2 Bulbs, 72 Watts
The 520UVB-NB is the least powerful 500 Series UVB-Narrowband device.
It is suitable for people that require lower dosages, such as vitiligo patients;
or for those needing to treat only a small area, such as the fingers.
These people may wish to also consider the
SolRx 100 Series Handheld.
|
530UVB-NB
3 Bulbs, 108 Watts
The 530UVB-NB is a good choice for basic "Spot" treatment.
It provides reasonable treatment times for most people.
Those treating hands or feet may wish to consider the 550UVB-NB because it has better UV-light
uniformity at the guard surface, and will provide shorter treatment times,
which can be lengthy for the thick skin in these areas.
|
550UVB-NB
or
550UVB-NB-CR
5 Bulbs, 180 Watts
The 550UVB-NB is the most powerful device in the 500 Series family.
It will provide the shortest treatment times and the most uniform UV-light at the guard surface.
The 550UVB-NB-CR is a special "Clinic Rated" unit designed specifically for heavy use in a phototherapy clinic.
It has a blower fan to keep the hood and bulbs cool,
and is electrically rated for "low leakage" hospital use.
Home users do not need to consider this model.
