Some more of my observations .... (but not of the Glamox FL60N Wide beam floodlights) - or - (the features seen mounted to the outboard surface of the port deck-edge walkway/catwalk screen.... this time


obviously someone has outstanding works to complete judging by the pack of cable ties left in the bag stuffed in the joint to the left of the access panel to the right of the picture Harry ..... ;)

Never having seen a plethera of installation such as this - has anyone got the answer as to the purpose of these features?

Further to the series of posts on the previous page (starting midway down) with the following post - this is the first image I have observed these titlting antenna in the raised position.

Nice touch.

Do I see three HF radio masts forward of the main bridge? I thought the QLZ class had new technology that meant they didn‘t need them. I haven‘t seen them before....

Well; the tweeter GS is correct - but only in part:-
- correct that the two normally horizontally stowed (and cleated down) tilting whip aerials/antenna have now been photographed/observed in the raised position (vertical).
- not necessarily correct in the assumption that the two tilting whips are in fact HF.
- incorrect in the assumption that the aftmost mast is a radio 'mast' - since it is actually a PIN mast (rigged and de-rigged as and when?) with a main light and standby light mounted at/near it's top (poss navigation and/or working light).


The tilting whip aerials/antenna lowered to horizontal and cleated.

Some more of my observations .... (but not of the Glamox FL60N Wide beam floodlights).... this time the feature can be seen mounted to the outboard surface of the 'stbd qtr deck edge catwalk screen'

This feature was noted when the two QEC carriers were alongside in Portsmouth Dockyard.

Having noticed the variation it was then obvious (in hindsight) that QNLZ R08 had sailed for Westlant 19 so adorned :oops: ... in fact further viewing of images revealed that the appendage was already in situ on QNLZ 08 in June 2019.

David, re your:- How is the 'blue' colour produced?

Since reading your question (copied above), the subject has played on my mind.

The answer might now be contained in this and the following post - so let's see what you think.


1st some observations that might identify the deck edge/cat walk screen floodlights used to illuminate the islands:-

Thank you for the trouble you have gone to Harry, my thoughts went back to when we used to have red night lighting below decks to prepare the eyes for night vision. Never really thought about the reason or theory, so asked Uncle Google who came back with this amongst others:

Blue versus red light for preserving night vision
I read on this forum an earlier post from a strong proponent of blue light for preserving night vision. As a pilot, I've been using red cockpit lighting for decades, and I know the FAA expended a lot of effort in biomedical research -- finally concluding red light was best.

So why the disagreement? I did some research and found the following three reasons for favoring red light over blue:

1) Producing dim blue light from an incandescent bulb that is dimmed by running at reduced voltage produces no blue light (in accordance with Planck's law), so in pre-LED days it was practically difficult to produce dim blue light without running an incandescent lamp at higher voltage (higher color temperature) and using a dense blue filter to make it dim.
2) The center of the human fovea, the part of the eye that you use to read printed materials and finely detailed charts, is blind to dim blue light: https://www.osapublishing.org/josa/abst ... 57-11-1289
The rods can take over for blue-blindness in brighter light.
3) The rods, which we depend on to see dimly lit objects, are much less sensitive to red than to green or blue light. So at equal intensities dim red ambient light has much less of an effect on degrading night vision than does blue light. (Note the qualification: "at equal intensities." You don't need as much blue light to see in the dark.)

In the past, pilots had analog instruments and spent a great deal of time reading printed procedures and studying paper charts using ambient light. They needed to use the blue-blind parts of their eyes. Today, modern aircraft and boats frequently have "glass" cockpits with electronic displays with direct lighting where resolving fine details on paper are less frequently needed. Here, blue light is less of a hindrance, and producing dim blue ambient light with LEDs is easily accomplished. And since the blue cones are more sensitive than red cones, so you need less blue light than you need red to see nearby objects. If you don't need to read finely detailed charts, analog instruments and printed matter, you may be better off with blue light.

All of this assumes normal color vision. In the case of pilots, they are tested for color vision and are usually restricted no night flying if they have any color blindness. The FAA research completely disregards the night vision effects for color blind pilots.

The above comes from - https://www.cruisersforum.com/forums/f1 ... 09780.html - which being a Forum has other comments below it.

Appears you are on the right track.
