Sony DSC-S70

I saw this week that now they’ve changed back to Sylvania for HID and to Cree for circline fluorescent. So that’s why the GE are on clearance.

@Baked bagel 11. Hi Tom! Yes. I forgot about the Italio! They are common in Norway for i saw loads when I went, and also popular in Italy I believe. I will try and get a pic of a Italio when I go to Italy after Christmas.
@LightsoftheWest the Piano is actually quite beautiful, I wouldn’t give it Stunning but I would just say it’s just Beautiful.

The Schréder Piano is, IMO, the most attractive LED street light ever produced.

I think for me that title would go to something like an AEC Illuninazione Italo 2.

Not too sure. I think my lowest is my 70w OVZ which is outside in service now.

One of the Most beautiful LED fixtures to exist. 

There atleast 3 main different types (wattages) of 3.5v mini bulb

The original ones (which were a lower current/wattage)
The 'superbright' type (which were indeed brighter, and a higher current/wattage)
The newer ones (which were a lower current/wattage than superbright (and somewhat lower than the original))
A 'energy saver' version does exist too, but is rare.

With 2.5v bulbs there are 6+ types!
All these different bulbs makes it confusing & hard for people.

Then you have different voltages ontop of that

--------
The key with mini bulbs is matching current on bulbs...
Say (as pure example) the set had 100ma bulbs, and you put in a 150ma bulb, that bulb would be dimmer.
Now say you did the opposite, put a 100ma bulb in a set with 150ma bulbs, that bulb would be brighter.
...and here's where things get interesting:
If you were to put a 12v (or any other voltage) 100ma bulb in a set with 2.5v 100ma bulbs, all would light at their correct brightness!
So as long as total bulb voltage added up to 120(or more) you can mix different voltages of bulbs in a set with zero issues.
But the thing is, light companies decided to go with different current ratings for different voltages of bulbs. (and ontop of that different currents of the same voltage)

The real danger here is fire

Wood is not a perfect insulator, it does pass some leakage current, initially tiny in the 100's uA range or less. The current breaks down the material and turns the wood into elemental carbon, slowly creating a carbon filament embedded within the thickness of the wood beam between the metal screws

As more wood is converted into carbon, the process accelerates. At some point it will abruptly turn into a runaway, with a glowing carbon filament igniting the wood from within

Additionally, this conversion to carbon removes any structural strength from the wood in the same way as rot does. It looks like they put those screws into a beam that is part of the house. This one does not seem structurally critical (it's not a huge beam, and there is no array of identical ones through the room), but if it's anything significant, something might come crashing down if the fire won't get it first

It is not about the voltage rating, but how fast the lamps heat up

The 3.5V lamps you used have lower thermal mass (possibly due to thinner filament), so they heat faster than the other lamps in the string

As the lamps heat up their resistance rises, and so does the share of the voltage they take from the series circuit. They heat up more, the resistance rises more, and so on. Suddenly they get a voltage which is not 3.5V but several times higher, before the other lamps warmed up at all

It will likely be ok if you use identical new lamps for all of the lamps in the string at once, as long as there is no variation between the individual lamps that will cause the same effect or non-uniform filament inside the lamps themselves
