Our neighbor's bucket light (which I suspect to be coated MV) lights a large area, but is soft and non-disturbing.
But beware of the coated MV bulbs that just diffuse the light, no actual phosphor.

Where are daylight fluorescents when you need them?

I would guess coated would give better illumination at a distance.


Really?  I would've thought the coated version would be reduced vs clear?  

Hmm.  I just might have to pick up a coated lamp to find out which one I like.  I might like the 'pink-white' lighting vs the 'green-white'.

Everything has been working fine for days. 

I decided to remain with the clear lamp.  The bugs are happy, as some decided to 'stick' around - on the bulb.   Grin

The photocell unit is working great, maybe even better, as far as turning on a bit later and off a little sooner.  This is because the cell is pointing North, where it sees the sky, whereas before, the old unit was pointed South - looking into the darker trees nearby. 

Thanks everyone.

We will have to see how long these modern photocells last.

Versus what?

The old photo controller plastic cover was quite yellowed and brittle over time, so I suspect it was there for some years, I just don't know how long.  The building looks like it was built in the 1960s.  When was the security light was installed, I don't know, but the on/off switch near the door, inside, was bypassed... so some standard outdoor fixture was originally there. 

It's raining now.  The first test of rain falling on the new lamp while it's on.  Hope it don't BLOW!  Grin

The modern "cheap" photocell/controllers seem to not be lasting long, compared to the "premium" commercial-grade ones.
And this seems to be a relatively modern bucket light.
I know of bucket lights with bare bulbs still working today, so yours should be OK.

Yeah, it made it through several days of rain so far.  I just didn't know if a new lamp would hold up to the rain like an old one.

Next, one day I just may take it down to see if I can adjust the socket so as to move the wire shadow off the yard.  Cheesy


I was thinking if I could overlay some sort of 'magnifier' over the photocell if that would help it turn on a bit later and off a bit sooner.

The problem with the magnifier is that it will make the PC degrade faster.

Oh?  Even though it's pointing North?

PCs degrade because of the UV light, which is present in sunlight.
By putting a magnifier in front of it, you are increasing the brightness, but also making it degrade faster because of the higher UV.

How about something that's anti-UV? If something like that exists.

I have never understood why they can't make glass photocells... those would never be affected by UV.

If the cell is openable you can probably tweak either the mechanic (move the tripping point of the contact, maybe there is a setting screw for that) or the electrics (lower a little the resistor value so there is more current)



If no try to put a bright "cube" in front of the cell window at some distance in front of it :

N
^
|          /\
|       /     \
|       \     /
|         \/



         (__) cell


So in dawn and dusk the cell window sees not the darkening sky but the side wall of the cube illuminated in the sunlight

I got some pics of the old controller:

There you go, use that screw to set the tripping point
