That is a shame.
Although it is a poor substitute for previous offerings, it is better than
nothing, and continues to be in daily use here.

Sorry, no is the answer. The Lumitest has now been discontinued.
You can buy colour testers that have light probes built in, such as the
Colorstar, or you can buy Ray The Handy Mobility Aid, which also has a light
probe built in, but the Lumitest is no more.
All the best
Steve

Yes is the simple answer from a company in Austria, retailed in this country by
Comproom.
I have one such device, and the purchase process seems to be easier, and
financially equivalent, through the UK supplier rather than the import route.
My review and criticism of the device follows.
I cannot whole-heartedly recommend it as it is rather cumbersome and, in my
view, tries to be too clever in the current market of Smart Phones which can
perform the more general functions which it is designed to perform.
For my part, I would like a light probe with a small single detector of light
from dark to intense, whereby the probe could be manipulated with a single
hand, probably with an index finger guiding the end of the probe over an area
(or LED) of interest, which may have been predefined by some form of preferred
tactile marking.
Although I have a variety of apps on my iPhone, and other auditory devices, one
which can detect a small single illuminated small light, or LED, would be very
useful, maybe with the ability to determine between red and green when a TV,
VCR, or similar unit is powered or unpowered.
In these days of micro-electronics, I suspect that one could be designed to be
inserted into a biro-style holder, and designed to be switched on with either
the guiding or a supporting finger.
The electronics is incredibly simple, being either a discrete component
A-stable multi-vibrator, or with a chip such as an NE555 (or modern equivalent)
with a Light Emitting Diode in the timing chain.
Perhaps a purpose-designed chip could be designed and built should the
appropriate home, educational, or commercial facilities be available.
The level of design sophistication could range from GCSE to simple
micro-electronics at low degree level.
The issue is that of bringing it from prototype phase, through testing, and
then into production.
From then on, the usual issue is marketing, however, in the world of "the
blind", there is an established market which has its own multi-level layers
which are usually the barrier in the establishment of a new product when
launching it as a cold idea to the general public.
There is one other issue. The higher it goes up the academic chain, the
greater the expected financial return to the higher educational establishments.
Sorry to have waxed eloquent for so long, but these are my personal thoughts
and previously written notes on the subject.
In years gone by, in its catalogue, the RNIB had a simple solution which has
long-sinced disappeared owing to its swing toward low sight rather than no
sight.

Does anyone know if you can still buy a light probe now or not? with thanks in
advance.
