I wholeheartedly agree with you Jag. How did this ever be allowed to get
this far with something so fundamental. In the era of UTMC when we are
supposed to be working towards interoperability between systems, we will
end up with the very basic of Traffic signal equipment, not being
compatible!

Further to my email of 30th October regarding 'ELV supplies and HA
specification' you will now appreciate that the problem will be further
exarcerbated by the fact that ELV controller outputs will be different
for the controllers from Blue and Red corners.
We must force the HA to be prescriptive on ELV supply!

Jag

I replaced all Mellor heads about 3 yrs ago at a junction with the
original Blue corner LED's. Unfortunately the failure rate was too high
to make them cost effective: 3 lamps in one year.
However, the new LED heads with the Centre mounted Led Source (***) have
proven very reliable and I am happy with them. In Sefton, we now have
many sites with these lanterns... good lantern design too.
The only dampener is that these particular heads cannot be converted (so
I'm told) to work with the new Extra Low Voltage controllers, they will
have a specifically designed LED head which obviously does not need a
power supply. So creating an ELV site where you have existing LED heads
would not seem as simple as replacing the controller and removing some
PSU's.
I don't know if any kind of converter may become available, I will check
with Mr Blue. (Blue sky thinking required, presumably).

Quick straw poll.
What are peoples experiences with the robustness of signal heads from
the red and blue corner?
From practical experience does one survive up better than another.
